วิธีการเผื่อระยะความกว้าง สูง ของเหล็กฉากบ่ารับแผ่นตะแกรง
ควรออกแบบเตรียมบ่ารับให้กว้างและสูงพอดีกับแผ่นตะแกรง เพื่อความแข็งแรงและปลอดภัยของการใช้งาน การติดตั้งตะแกรงระบายน้ำจะต้องออกแบบเตรียมบ่ารองรับให้กว้างและสูงพอดีกับแผ่นตะแกรงระบายน้ำ โดยมาตรฐานทั่วไป ตะแกรงเหล็กและพลาสติคมีความกว้าง 2 ขนาด ได้แก่กว้าง 25cm. และ 30cm. ดังนั้นบ่ารับตะแกรง(รูปตัว L) จะต้องใช้เหล็กฉากวางลงไปก่อนเทคอนกรีต โดยเว้นความสูงไว้ 25-30mm. (ขึ้นอยู่กับประเภทของตะแกรง) เพื่อให้ตะแกรงที่วางลงไปเสมอพอดีกับพื้น ไม่สะดุดเวลารถเข็นหรือคนเดินผ่าน ส่วนความกว้างของบ่ารับเมื่อวัดแล้วจะต้องเว้นเผื่อไว้ 6-10mm. ดังนี้

ระยะความกว้างของบ่ารับแผ่นเกรตติ้ง จะต้องบวกเพิ่มข้างละ 3-5mm.รวม 2 ข้างเป็น 6-10mm. เพื่อให้สามารถวางแผ่นตะแกรงลงไปได้พอดี ไม่แน่นหรือหลวมเกินไป

Ex-1 กรณีใช้ตะแกรง กว้าง 25cm. จะต้องเตรียมบ่ารับเผื่อไว้ = 25.5-26.0 cm.

Ex-2 กรณีใช้ตะแกรง กว้าง 30cm. จะต้องเตรียมบ่ารับเผื่อไว้ = 30.5-31.0 cm.

ไฟเบอร์กล๊าสคืออะไร | FibreGlass Definition

ผลิตภัณฑ์ไฟเบอร์กลาส เป็นคำแปลมาจากคำว่า Fiberglass Reinforced Plastic หรือ Glass Reinforced Composite หรือผลิตภัณฑ์พลาสติกที่ใส่วัสดุอื่นเพื่อเสริมความแข็งแรง (มีวัสดุมากกว่า 2 ชนิดมาประสานกัน) วัสดุที่นำมาเสริมแรงให้พลาสติกคือ “ใยแก้ว” ซึ่งมีลักษณะอ่อนนุ่มแต่เหนียว ทนความร้อนได้สูง ส่วนพลาสติกที่นำมาใช้เป็นเนื้อ ต้องเป็นชนิดที่มีความแข็งมาก ซึ่งถ้าไม่มีการเสริมแรงแล้วจะเปราะ ดังนั้นเราจึงเลือกเอาพลาสติกประเภท โพลิเอสเทอร์เรซิ่น ไวนิลเอสเทอร์เรซิ่น และอีพอกซี่เรซิ่น พลาสติกจำพวกนี้เป็นพลาสติกเหลวซึ่งภายหลังจากการผสมกับ ตัวช่วยเร่งปฏิกิริยา หรือ ตัวทำให้แข็ง แล้วจะเกิดปฏิกิริยาทางเคมี มีความร้อนเกิดขึ้นสูงกว่า100?C. แล้วจะเปลี่ยนเป็นพลาสติกแข็งและจะไม่คืนรูปอีกซึ่งเรียกว่ากระบวนการ เทอร์โมเซ็ตติ้ง (Thermoseting)
โรงงานผู้ผลิตเกรตติ้งฝาบ่อฝาท่อตะแกรงระบายน้ำ grating manhole ดังนั้นการสร้างผลิตภัณฑ์ขึ้นมาโดยวิธีการดังกล่าวแล้ว จึงเรียกได้ว่าเป็น ผลิตภัณฑ์พลาสติกเสริมแรง ด้วยใยแก้ว หรือ FRP ซึ่งเราเรียกง่ายๆ ว่า ผลิตภัณฑ์ไฟเบอร์กลาส หรือ ผลิตภัณฑ์เอฟอาร์พี
ไฟเบอร์กลาสหรือเส้นใยแก้วแบ่งได้เป็นสองประเภทตามลักษณะของเส้นใย คือเส้นใยต่อเนื่องคล้ายกับเส้นด้าย ที่สามารถนำมาถักทอให้เป็นผืนผ้า (fiberglass fabric) ผ้าที่ได้จะไม่ดูดซึมน้ำ ไม่หดตัว ป้องกันความร้อนได้ดี ส่วนมากจะนำไปใช้ในด้านอุตสาหกรรม เช่น ทำเป็นผ้าม่านกันสะเก็ดไฟ ส่วนเส้นใยแก้วอีกประเภทหนึ่งจะเป็นเส้นใยที่สั้นไม่ต่อเนื่อง มักนำมาใช้ทำเป็นฉนวนกันความร้อน และ ฉนวนกันเสียง ซึ่งมีลักษณะเป็นแผ่นหนานุ่ม
ส่วนผสมหลักที่ใช้ผลิตเส้นใยแก้วคือ ทรายแก้ว (silica sand) ใช้เป็นสารสร้างแก้ว โซดาแอช (soda ash)และ หินปูน (limestone) สารสองอย่างหลังจะช่วยลดจุดหลอมเหลว นอกจากส่วนผสมหลักทั้งสามแล้วอาจมีส่วนผสมอื่นๆที่ใช้เพื่อปรับปรุงสมบัติต่างๆของเส้นใยแก้วเช่น บอแรกซ์ (borax) ฟันหินม้า (feldspar) แคลไซน์อะลูมินา (calcined alumina) แมกนีไซต์ (magnesite) เนฟฟีลีนไซยาไนต์ (nepheline syenite) และ ดินขาวเคโอลิน (kaolin clay)

Definition of polyester resin
any of various synthetic resins or plastics consisting of or made from polyesters: such as a resin that has the same chemical composition as the common polyester fiber but that is extruded as a film (as for use in packaging, as electrical insulation, or as a base for magnetic recording tapes) c : a thermosetting resin that is made from an unsaturated polyester (as one formed from a glycol and maleic acid or fumaric acid), cured by copolymerization (as with styrene), and often reinforced with fillers (as glass fibers) and that is used chiefly in impregnating and laminating and in making cast and molded products

For the thermal insulation material sometimes called fiberglass, see glass wool. For the glass fiber itself, also sometimes called fiberglass, see glass fiber. For similar composite materials in which the reinforcement fiber is carbon fibers, see carbon-fiber-reinforced polymer. Fiberglass (or fibreglass) is a type of fiber-reinforced plastic where the reinforcement fiber is specifically glass fiber. The glass fiber may be randomly arranged, flattened into a sheet (called a chopped strand mat), or woven into a fabric. The plastic matrix may be a thermosetting plastic – most often epoxy, polyester resin – or vinylester, or a thermoplastic.
The glass fibers are made of various types of glass depending upon the fiberglass use. These glasses all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes boron. To be used in fiberglass, glass fibers have to be made with very low levels of defects.
Fiberglass is a strong lightweight material and is used for many products. Although it is not as strong and stiff as composites based on carbon fiber, it is less brittle, and its raw materials are much cheaper. Its bulk strength and weight are also better than many metals, and it can be more readily molded into complex shapes. Applications of fiberglass include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, casts, surfboards, and external door skins.
Other common names for fiberglass are glass-reinforced plastic (GRP),[1] glass-fiber reinforced plastic (GFRP)[2] or GFK (from German: Glasfaserverst?rkter Kunststoff). Because glass fiber itself is sometimes referred to as “fiberglass”, the composite is also called “fiberglass reinforced plastic.” This article will adopt the convention that “fiberglass” refers to the complete glass fiber reinforced composite material, rather than only to the glass fiber within it.

โรงงานผู้ผลิตเกรตติ้งฝาบ่อฝาท่อตะแกรงระบายน้ำ grating manhole : Glass fibers have been produced for centuries, but mass production of glass strands was accidentally discovered in 1932 when Games Slayter, a researcher at Owens-Illinois, directed a jet of compressed air at a stream of molten glass and produced fibers. A patent for this method of producing glass wool was first applied for in 1933.Owens joined with the Corning company in 1935 and the method was adapted by Owens Corning to produce its patented “fibreglas” (one “s”) in 1936. Originally, fibreglas was a glass wool with fibers entrapping a great deal of gas, making it useful as an insulator, especially at high temperatures.
A suitable resin for combining the “fibreglass” with a plastic to produce a composite material was developed in 1936 by du Pont. The first ancestor of modern polyester resins is Cyanamid’s resin of 1942. Peroxide curing systems were used by then. With the combination of fiberglass and resin the gas content of the material was replaced by plastic. This reduced the insulation properties to values typical of the plastic, but now for the first time the composite showed great strength and promise as a structural and building material. Confusingly, many glass fiber composites continued to be called “fiberglass” (as a generic name) and the name was also used for the low-density glass wool product containing gas instead of plastic.
Ray Greene of Owens Corning is credited with producing the first composite boat in 1937, but did not proceed further at the time due to the brittle nature of the plastic used. In 1939 Russia was reported to have constructed a passenger boat of plastic materials, and the United States a fuselage and wings of an aircraft. The first car to have a fiber-glass body was a 1946 prototype of the Stout Scarab, but the model did not enter production.

นำส่วนผสมทั้งหมดหลอมในเตาไฟฟ้าที่อุณหภูมิสูงมากถึง 1370 องศาเซลเซียสเพื่อให้ได้น้ำแก้ว จากนั้นจะเข้าสู่กระบวนการรีดเป็นเส้นใยยาวโดยเส้นใยจะถูกดึงออกจากหัวรีดและถูกม้วนเก็บด้วยความเร็วที่สูงกว่าความเร็วของใยแก้วที่ถูกอัดออกจากหัวรีด ซึ่งเท่ากับเป็นการยืดดึงในขณะที่เส้นใยยังอ่อนตัวทำให้ได้เส้นใยขนาดเล็กลงก่อนการแข็งตัว หากต้องการทำเป็นเส้นใยสั้นก็ทำได้โดยการตัดด้วยแรงลม สามารถทำให้เส้นใยมีความยาวแตกต่างกันออกไป
อย่างไรก็ตาม ในขั้นตอนการหลอม ถ้าหากไม่มีการควบคุมคุณภาพของส่วนผสมให้บริสุทธิ์แล้วก็จำเป็นต้องหลอมและทำน้ำแก้วให้เป็นลูกแก้วก่อนเพื่อคัดลูกแก้วที่บริสุทธิ์มาหลอมให้เป็นน้ำแก้วใหม่อีกครั้ง แต่ถ้าหากมีการควบคุมคุณภาพของส่วนผสมแล้ว ก็สามารถรีดเส้นใยจากน้ำแก้วในเตาได้เลย
ส่วน”ไฟเบอร์กลาส”ในความหมายของวัสดุเสริมแรงนั้น ผลิตได้สองวิธี คือ วิธีแรกนำชิ้นส่วนต้นแบบมาขัดผิวด้านนอกด้วยขี้ผึ้งถอดแบบ วางผ้าใยแก้วบนชิ้นส่วนต้นแบบ ทาด้วยเรซินที่ผสมตัวทำให้แข็งให้มีความหนาตามต้องการ เมื่อเรซินแข็งตัวแล้วดึงชิ้นส่วนไฟเบอร์กลาสออกจากชิ้นส่วนต้นแบบ นำมาขัดแต่งผิวด้านนอกให้เรียบร้อย การสร้างชิ้นส่วนไฟเบอร์กลาสด้วยวิธีนี้จะขาดรายละเอียดและความสวยงามแตกต่างจากวิธีที่สองที่ใช้แม่พิมพ์ วิธีนี้จะเหมาะสำหรับชิ้นส่วนจำนวนมาก แต่มีขั้นตอนยุ่งยากกว่าวิธีแรก โดยเราต้องสร้างแม่พิมพ์ขึ้นมาจากชิ้นส่วนต้นแบบเสียก่อน เมื่อได้แม่พิมพ์ แล้วจึงนำมาสร้างชิ้นส่วนไฟเบอร์กลาสที่ต้องการ ชิ้นส่วนที่สร้างขึ้นมามีความสวยงามเหมือนกับต้นแบบทุกประการ และสามารถเสริมความแข็งแรงในบริเวณที่ต้องการโดยเพิ่มความหนาของใยแก้วหลายๆ ชั้น
The process of manufacturing fiberglass is called pultrusion.[citation needed] The manufacturing process for glass fibers suitable for reinforcement uses large furnaces to gradually melt the silica sand, limestone, kaolin clay, fluorspar, colemanite, dolomite and other minerals to liquid form. It is then extruded through bushings, which are bundles of very small orifices (typically 5–25 micrometres in diameter for E-Glass, 9 micrometres for S-Glass). These filaments are then sized (coated) with a chemical solution. The individual filaments are now bundled in large numbers to provide a roving. The diameter of the filaments, and the number of filaments in the roving, determine its weight, typically expressed in one of two measurement systems: yield, or yards per pound (the number of yards of fiber in one pound of material; thus a smaller number means a heavier roving). Examples of standard yields are 225yield, 450yield, 675yield. tex, or grams per km (how many grams 1 km of roving weighs, inverted from yield; thus a smaller number means a lighter roving). Examples of standard tex are 750tex, 1100tex, 2200tex.
These rovings are then either used directly in a composite application such as pultrusion, filament winding (pipe), gun roving (where an automated gun chops the glass into short lengths and drops it into a jet of resin, projected onto the surface of a mold), or in an intermediary step, to manufacture fabrics such as chopped strand mat (CSM) (made of randomly oriented small cut lengths of fiber all bonded together), woven fabrics, knit fabrics or uni-directional fabrics. Chopped strand mat
Chopped strand mat or CSM is a form of reinforcement used in fiberglass. It consists of glass fibers laid randomly across each other and held together by a binder.
It is typically processed using the hand lay-up technique, where sheets of material are placed in a mold and brushed with resin. Because the binder dissolves in resin, the material easily conforms to different shapes when wetted out. After the resin cures, the hardened product can be taken from the mold and finished. Using chopped strand mat gives a fiberglass with isotropic in-plane material properties.

An individual structural glass fiber is both stiff and strong in tension and compression—that is, along its axis. Although it might be assumed that the fiber is weak in compression, it is actually only the long aspect ratio of the fiber which makes it seem so; i.e., because a typical fiber is long and narrow, it buckles easily.[7] On the other hand, the glass fiber is weak in shear—that is, across its axis. Therefore, if a collection of fibers can be arranged permanently in a preferred direction within a material, and if they can be prevented from buckling in compression, the material will be preferentially strong in that direction.
Furthermore, by laying multiple layers of fiber on top of one another, with each layer oriented in various preferred directions, the material’s overall stiffness and strength can be efficiently controlled. In fiberglass, it is the plastic matrix which permanently constrains the structural glass fibers to directions chosen by the designer. With chopped strand mat, this directionality is essentially an entire two dimensional plane; with woven fabrics or unidirectional layers, directionality of stiffness and strength can be more precisely controlled within the plane.
A fiberglass component is typically of a thin “shell” construction, sometimes filled on the inside with structural foam, as in the case of surfboards. The component may be of nearly arbitrary shape, limited only by the complexity and tolerances of the mold used for manufacturing the shell.
The mechanical functionality of materials is heavily relied on the combined performances of both the resin (AKA matrix) and fibres. For example, in severe temperature condition (over 180 ?C) resin component of the composite may lose its functionality partially because of bond deterioration of resin and fibre.[8] However, GFRPs can show still significant residual strength after experiencing high temperature (200 ?C).

Composite (GFRP) Gratings : What is GFRP (Glass Fiber Reinforced Plastic)? GFRP is a composite material made of a polymer matrix reinforced with fiber, aiming to form better physical and chemical properties. GFRP is a production material such as metal, wood, glass, concrete. GFRP materials has important advantages as against other production materials, new features can be acquired according to requirements. What is GFRP Grating? Molded GFRP gratings are produced in special molds with wet lamination process, consist of glass fiber, resin, additives and pigment. After these raw materials harden, GFRP gratings are pressed out of the mold. Molded GFRP gratings are light, anti-corrosive, have high chemical and physical resistances and electrically non-conductive. Components: Resin, glass fiber, additives and pigment are the basic components of the GFRP materials. It can be produced any material which are proper for the requirements by changing these components. Resin: Chemical resistance, flexibility and UV resistance of the GFRP gratings are determined by the resin. Resins are chose according to the environment; orthophthalic resin for general usage, isophthalic resin for chemical environment and vinyl ester resin for extremely heavy chemical environment. Glass Fiber: Multi-layered continuous glass fibers are used in production. Molded GFRP gratings have high mechanical resistance due to glass fiber. Additives: Additives such as UV stabilizers, flame retardants and low smoke density retardants increase mechanical and chemical resistance and add new superior features. Pigment: Pigments make it possible to give the GFRP gratings any color. This makes it happen to use GFRP gratings in architectural projects.

Fibre-reinforced plastic (FRP) (also called fibre-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinylester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.
FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armor as well.
A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers the result is referred to as a plastic. Composite plastics refer to those types of plastics that result from bonding two or more homogeneous materials with different material properties to derive a final product with certain desired material and mechanical properties. Fibre-reinforced plastics are a category of composite plastics that specifically use fibre materials to mechanically enhance the strength and elasticity of plastics. The original plastic material without fibre reinforcement is known as the matrix or binding agent. The matrix is a tough but relatively weak plastic that is reinforced by stronger stiffer reinforcing filaments or fibres. The extent that strength and elasticity are enhanced in a fibre-reinforced plastic depends on the mechanical properties of both the fibre and matrix, their volume relative to one another, and the fibre length and orientation within the matrix.[1] Reinforcement of the matrix occurs by definition when the FRP material exhibits increased strength or elasticity relative to the strength and elasticity of the matrix alone.
FRP can be applied to strengthen the beams, columns, and slabs of buildings and bridges. It is possible to increase the strength of structural members even after they have been severely damaged due to loading conditions. In the case of damaged reinforced concrete members, this would first require the repair of the member by removing loose debris and filling in cavities and cracks with mortar or epoxy resin. Once the member is repaired, strengthening can be achieved through wet, hand lay-up of impregnating the fibre sheets with epoxy resin then applying them to the cleaned and prepared surfaces of the member. Two techniques are typically adopted for the strengthening of beams, relating to the strength enhancement desired: flexural strengthening or shear strengthening. In many cases it may be necessary to provide both strength enhancements. For the flexural strengthening of a beam, FRP sheets or plates are applied to the tension face of the member (the bottom face for a simply supported member with applied top loading or gravity loading). Principal tensile fibres are oriented in the beam longitudinal axis, similar to its internal flexural steel reinforcement. This increases the beam strength and its stiffness (load required to cause unit deflection), however decreases the deflection capacity and ductility. For the shear strengthening of a beam, the FRP is applied on the web (sides) of a member with fibres oriented transverse to the beam’s longitudinal axis. Resisting of shear forces is achieved in a similar manner as internal steel stirrups, by bridging shear cracks that form under applied loading. FRP can be applied in several configurations, depending on the exposed faces of the member and the degree of strengthening desired, this includes: side bonding, U-wraps (U-jackets), and closed wraps (complete wraps). Side bonding involves applying FRP to the sides of the beam only. It provides the least amount of shear strengthening due to failures caused by de-bonding from the concrete surface at the FRP free edges. For U-wraps, the FRP is applied continuously in a ‘U’ shape around the sides and bottom (tension) face of the beam. If all faces of a beam are accessible, the use of closed wraps is desirable as they provide the most strength enhancement. Closed wrapping involves applying FRP around the entire perimeter of the member, such that there are no free ends and the typical failure mode is rupture of the fibres. For all wrap configurations, the FRP can be applied along the length of the member as a continuous sheet or as discrete strips, having a predefined minimum width and spacing. Slabs may be strengthened by applying FRP strips at their bottom (tension) face. This will result in better flexural performance, since the tensile resistance of the slabs is supplemented by the tensile strength of FRP. In the case of beams and slabs, the effectiveness of FRP strengthening depends on the performance of the resin chosen for bonding. This is particularly an issue for shear strengthening using side bonding or U-wraps. Columns are typically wrapped with FRP around their perimeter, as with closed or complete wrapping. This not only results in higher shear resistance, but more crucial for column design, it results in increased compressive strength under axial loading. The FRP wrap works by restraining the lateral expansion of the column, which can enhance confinement in a similar manner as spiral reinforcement does for the column core.

Applications of Fibre Glass Grating โรงงานผู้ผลิตเกรตติ้งฝาบ่อฝาท่อตะแกรงระบายน้ำ grating manhole

A cryostat made of fiberglass Fiberglass is an immensely versatile material due to its light weight, inherent strength, weather-resistant finish and variety of surface textures.
The development of fiber-reinforced plastic for commercial use was extensively researched in the 1930s. It was of particular interest to the aviation industry. A means of mass production of glass strands was accidentally discovered in 1932 when a researcher at Owens-Illinois directed a jet of compressed air at a stream of molten glass and produced fibers. After Owens merged with the Corning company in 1935, Owens Corning adapted the method to produce its patented “Fiberglas” (one “s”). A suitable resin for combining the “Fiberglas” with a plastic was developed in 1936 by du Pont. The first ancestor of modern polyester resins is Cyanamid’s of 1942. Peroxide curing systems were used by then. During World War II, fiberglass was developed as a replacement for the molded plywood used in aircraft radomes (fiberglass being transparent to microwaves). Its first main civilian application was for the building of boats and sports car bodies, where it gained acceptance in the 1950s. Its use has broadened to the automotive and sport equipment sectors. In production of some products, such as aircraft, carbon fiber is now used instead of fiberglass, which is stronger by volume and weight. Advanced manufacturing techniques such as pre-pregs and fiber rovings extend fiberglass’s applications and the tensile strength possible with fiber-reinforced plastics.
Fiberglass is also used in the telecommunications industry for shrouding antennas, due to its RF permeability and low signal attenuation properties. It may also be used to conceal other equipment where no signal permeability is required, such as equipment cabinets and steel support structures, due to the ease with which it can be molded and painted to blend with existing structures and surfaces. Other uses include sheet-form electrical insulators and structural components commonly found in power-industry products. Because of fiberglass’s light weight and durability, it is often used in protective equipment such as helmets. Many sports use fiberglass protective gear, such as goaltenders’ and catchers’ masks.
Storage tanks
Several large fiberglass tanks at an airport Storage tanks can be made of fiberglass with capacities up to about 300 tonnes. Smaller tanks can be made with chopped strand mat cast over a thermoplastic inner tank which acts as a preform during construction. Much more reliable tanks are made using woven mat or filament wound fiber, with the fiber orientation at right angles to the hoop stress imposed in the side wall by the contents. Such tanks tend to be used for chemical storage because the plastic liner (often polypropylene) is resistant to a wide range of corrosive chemicals. Fiberglass is also used for septic tanks.
House building
Glass-reinforced plastics are also used to produce house building components such as roofing laminate, door surrounds, over-door canopies, window canopies and dormers, chimneys, coping systems, and heads with keystones and sills. The material’s reduced weight and easier handling, compared to wood or metal, allows faster installation. Mass-produced fiberglass brick-effect panels can be used in the construction of composite housing, and can include insulation to reduce heat loss.

Some surfaces like tile and laminate are prone to becoming extremely slippery when moist. Accidents that occur as a result of a misplaced foot can be embarrassing, painful, and very costly. It is always a good idea to have anti-slip floor mats set in place, especially in an area prone to wet conditions. Rubber-Cal’s line of safety flooring mats is an ideal and affordable solution to safeguarding your area from the dangers of moisture while making sure that you and your guests are secure on your feet. A huge part of this safety lies in the rubber material used to make our anti-skid flooring. It enhances traction and inhibits moisture at the same time. Every type of floor, whether it is residential, commercial, or industrial, can benefit from the presence of rubber traction mats. The primary feature about anti-slip floor mats is that they increase the safety of wet areas. Business owners take an interest in rubber non-slip mats because of this reason. Some commercial venues like restaurant kitchens are hazardous areas that see lots of loose liquids getting onto their existing floors. Without any safety flooring in place, the risk of workers slipping and injuring themselves is far greater. In addition to kitchen areas, these mats are ideal to place at entryways when there are wet weather conditions. With rubber anti-slip floor mats placed in such areas, people will experience more security while on their feet. This safety is provided in large part thanks to the rubber material that is used in our traction mats.

Types of glass fiber used Main article: Glass fiber Composition: the most common types of glass fiber used in fiberglass is E-glass, which is alumino-borosilicate glass with less than 1% w/w alkali oxides, mainly used for glass-reinforced plastics. Other types of glass used are A-glass (Alkali-lime glass with little or no boron oxide), E-CR-glass (Electrical/Chemical Resistance; alumino-lime silicate with less than 1% w/w alkali oxides, with high acid resistance), C-glass (alkali-lime glass with high boron oxide content, used for glass staple fibers and insulation), D-glass (borosilicate glass, named for its low Dielectric constant), R-glass (alumino silicate glass without MgO and CaO with high mechanical requirements as Reinforcement), and S-glass (alumino silicate glass without CaO but with high MgO content with high tensile strength) Naming and use: pure silica (silicon dioxide), when cooled as fused quartz into a glass with no true melting point, can be used as a glass fiber for fiberglass, but has the drawback that it must be worked at very high temperatures. In order to lower the necessary work temperature, other materials are introduced as “fluxing agents” (i.e., components to lower the melting point). Ordinary A-glass (“A” for “alkali-lime”) or soda lime glass, crushed and ready to be remelted, as so-called cullet glass, was the first type of glass used for fiberglass. E-glass (“E” because of initial Electrical application), is alkali free, and was the first glass formulation used for continuous filament formation. It now makes up most of the fiberglass production in the world, and also is the single largest consumer of boron minerals globally. It is susceptible to chloride ion attack and is a poor choice for marine applications. S-glass (“S” for “stiff”) is used when tensile strength (high modulus) is important, and is thus an important building and aircraft epoxy composite (it is called R-glass, “R” for “reinforcement” in Europe). C-glass (“C” for “chemical resistance”) and T-glass (“T” is for “thermal insulator”—a North American variant of C-glass) are resistant to chemical attack; both are often found in insulation-grades of blown fiberglass. ใยแก้วหรือไฟบอร์กลาสเป็นวัสดุสังเคราะห์ชนิดหนึ่ง เป็นวัตถุดิบหลักที่ใช้ในการขึ้นรูปงานไฟเบอร์กลาส โดยทั่วไปจะแบ่งประเภทใยแก้วออกเป็นชนิต่างๆตามคุณสมบัติ ดังนี้

การแข็งตัวของเรซิ่น

โพลีเอสเทอร์เรซิ่นสามารถแข็งตัวได้หลายวิธีดังนี้
1. โดยใช้ตัว catalyst หรือตัวทำให้แข็ง + ความร้อน
2. โดยใช้ตัว catalyst หรือตัวทำให้แข็ง + ตัวช่วยเร่งปฏิกิริยา promote/accelerator ที่อุณหภูมิห้อง
3. โดยใช้แสงอุลตร้าไวโอเลต
4. โดยใช้อิเลคตรอน
5. โดยใช้แสงแดด
6. โดยใช้ความร้อน
โดยทั่วไปการแข็งตัวของเรซิ่นแบ่งออกเป็น 2 ช่วงคือ ช่วงที่ 1. gel time คือช่วงหลังจากเติมตัว catalyst แล้วจนเรซิ่นจับตัวเป็นวุ้น ช่วงที่ 2. cure time คือช่วงที่เรซิ่นแข็งตัวเต็มที่และเป็นช่วงที่เรซิ่นเย็นตัวลงหลังจากที่มีความร้อนสูงในขณะทำปฏิกิริยา

องค์ประกอบที่มีผลต่อการแข็งตัวของเรซิ่น

1. อุณหภูมิ อุณหภูมิสูงเรซิ่นแข็งตัวเร็วกว่าอุณหภูมิต่ำ
2. ปริมาณตัวเร่งฯ และ ตัวช่วยเร่งฯ ปริมาณที่มากแข็งตัวเร็วกว่าปริมาณที่น้อย
3. ความชื้นหรือน้ำ ความชื้นสูงการแข็งตัวของเรซิ่นจะช้าลง ผิวงานขึ้นฝ้ามัว โดยปกติปริมาณน้ำที่อยู่ในเรซิ่นจะต้องมีค่าไม่เกิน 0.05%
4. ปริมาณออกซิเจน ออกซิเจนเป็นตัวป้องกันการแข็งตัวของเรซิ่น ถ้าปริมาณออกซิเจนสูง เช่นการกวนเรซิ่นมากๆ นานๆ การแข็งตัวของเรซิ่นจะช้าลง และออกซิเจนมีประโยชน์มากในเรื่องการยืดอายุการเก็บของเรซิ่น หากเริ่มเก็บเรซิ่นไว้นานขึ้น ควรสร้างออกซิเจนให้เกิดในถัง หรือปีบด้วยการกลิ้งถังไปมา เพื่อให้เรซิ่นข้างในเกิดการเคลื่อนไหว จะเกิดออกซิเจน และจะทำให้เรซิ่นมีอายุการเก็บเพิ่มขึ้นอีกเล็กน้อย

6. ABS (Acrylonitrile-Butadiene-Styrene)

ABS is a low cost engineering plastic that is easy to machine and fabricate. ABS is an ideal material for structural applications when impact resistance, strength, and stiffness are required. It is widely used for machining pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue. Natural (beige) ABS and black ABS are FDA compliant for use in food processing applications. The following physical property information is based on typical values of the base acrylonitrile-butadiene-styrene resin.
ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The polybutadiene, a rubbery substance, provides toughness even at low temperatures. For the majority of applications, ABS can be used between -20 and 80 C (-4 and 176 F) as its mechanical properties vary with temperature. The properties are created by rubber toughening, where fine particles of elastomer are distributed throughout the rigid matrix.
The most important mechanical properties of ABS are impact resistance and toughness. A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. The impact resistance can be amplified by increasing the proportions of polybutadiene in relation to styrene and also acrylonitrile, although this causes changes in other properties. Impact resistance does not fall off rapidly at lower temperatures. Stability under load is excellent with limited loads. Thus, by changing the proportions of its components, ABS can be prepared in different grades. Two major categories could be ABS for extrusion and ABS for injection moulding, then high and medium impact resistance. Generally ABS would have useful characteristics within a temperature range from ?20 to 80 C (?4 to 176 F). Lego bricks are made from ABS.
The final properties will be influenced to some extent by the conditions under which the material is processed to the final product. For example, molding at a high temperature improves the gloss and heat resistance of the product whereas the highest impact resistance and strength are obtained by molding at low temperature. Fibers (usually glass fibers) and additives can be mixed in the resin pellets to make the final product strong and raise the operating range to as high as 80 C (176 F). Pigments can also be added, as the raw material original color is translucent ivory to white. The aging characteristics of the polymers are largely influenced by the polybutadiene content, and it is normal to include antioxidants in the composition. Other factors include exposure to ultraviolet radiation, for which additives are also available to protect against.
ABS polymers are resistant to aqueous acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils, but they are swollen by glacial acetic acid, carbon tetrachloride and aromatic hydrocarbons and are attacked by concentrated sulfuric and nitric acids. They are soluble in esters, ketones, ethylene dichloride and acetone. Even though ABS plastics are used largely for mechanical purposes, they also have electrical properties that are fairly constant over a wide range of frequencies. These properties are little affected by temperature and atmospheric humidity in the acceptable operating range of temperatures.
ABS is flammable when it is exposed to high temperatures, such as those of a wood fire. It will melt and then boil, at which point the vapors burst into intense, hot flames. Since pure ABS contains no halogens, its combustion does not typically produce any persistent organic pollutants, and the most toxic products of its combustion or pyrolysis are carbon monoxide and hydrogen cyanide. ABS is also damaged by sunlight. This caused one of the most widespread and expensive automobile recalls in US history due to the degradation of the seatbelt release buttons.
ABS can be recycled, although it is not accepted by all recycling facilities. Production
ABS is derived from acrylonitrile, butadiene, and styrene. Acrylonitrile is a synthetic monomer produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking; styrene monomer is made by dehydrogenation of ethyl benzene — a hydrocarbon obtained in the reaction of ethylene and benzene.
ABS combines the strength and rigidity of acrylonitrile and styrene polymers with the toughness of polybutadiene rubber. While the cost of producing ABS is roughly twice the cost of producing polystyrene, it is considered superior for its hardness, gloss, toughness, and electrical insulation properties.

7. Polypropylene (PP) Plastic

What is Polypropylene (PP), and What is it Used For?
Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles. Polypropylene was first polymerized in 1951 by a pair of Phillips petroleum scientists named Paul Hogan and Robert Banks and later by Italian and German scientists Natta and Rehn. It became prominent extremely fast, as commercial production began barely three years after Italian chemist, Professor Giulio Natta, first polymerized it. Natta perfected and synthesized the first polypropylene resin in Spain in 1954, and the ability of polypropylene to crystallize created a lot of excitement. By 1957, its popularity had exploded and widespread commercial production began across Europe. Today it is one of the most commonly produced plastics in the world. CNC Cut Polypropylene Living Hinge Prototype Child Safe Lid, CNC Cut Polypropylene Living Hinge Prototype Child Safe Lid by Creative Mechanisms
According to some reports, the current global demand for the material generates an annual market of about 45 million metric tons and it is estimated that the demand will rise to approximately 62 million metric tons by 2020. The major end users of polypropylene are the packaging industry, which consumes about 30% of the total, followed by the electrical and equipment manufacturing, which uses about 13% each. Household appliances and automotive industries both consume 10% each and construction materials follows with 5% of the market. Other applications together make up the rest of the global polypropylene consumption.
Polypropylene has a relatively slippery surface which can make it a possible substitute for plastics like Acetal (POM) in low friction applications like gears or for use as a contact point for furniture. Perhaps a negative aspect of this quality is that it can be difficult to bond Polypropylene to other surfaces (i.e. it does not adhere well to certain glues that work fine with other plastics and sometimes has to be welded in the event that forming a joint is required). Although polypropylene is slippery at the molecular level, it does have a relatively high coefficient of friction – which is why acetal, nylon, or PTFE would be used instead. Polypropylene also has a low density relative to other common plastics which translates to weight savings for manufacturers and distributors of injection molded Polypropylene parts. It has exceptional resistance at room temperature to organic solvents like fats but is subject to oxidation at higher temperatures (a potential issue during injection molding).
One of the major benefits of Polypropylene is that it can be manufactured (either through CNC or injection molding, thermoforming, or crimping) into a living hinge. Living hinges are extremely thin pieces of plastic that bend without breaking (even over extreme ranges of motion nearing 360 degrees). They are not particularly useful for structural applications like holding up a heavy door but are exceptionally useful for non load-bearing applications such as the lid on a bottle of ketchup or shampoo. Polypropylene is uniquely adept for living hinges because it does not break when repeatedly bent. One of the other advantages is that polypropylene can be CNC machined to include a living hinge which allows for faster prototype development and is less expensive than other prototyping methods. Creative Mechanisms is unique in our ability to machine living hinges from a single piece of polypropylene.
Another advantage of Polypropylene is that it can be easily copolymerized (essentially combined into a composite plastic) with other polymers like polyethylene. Copolymerization changes the material properties significantly, allowing for more robust engineering applications than are possible with pure polypropylene (more of a commodity plastic on its own).
The characteristics mentioned above and below mean that polypropylene is used in a variety of applications: dishwasher safe plates, trays, cups, etc, opaque to-go containers, and many toys.

What are the Characteristics of Polypropylene? โรงงานผู้ผลิตเกรตติ้งฝาบ่อฝาท่อตะแกรงระบายน้ำ grating manhole
Some of the most significant properties of polypropylene are:
Chemical Resistance: Diluted bases and acids don’t react readily with polypropylene, which makes it a good choice for containers of such liquids, such as cleaning agents, first-aid products, and more.
Elasticity and Toughness: Polypropylene will act with elasticity over a certain range of deflection (like all materials), but it will also experience plastic deformation early on in the deformation process, so it is generally considered a “tough” material. Toughness is an engineering term which is defined as a material’s ability to deform (plastically, not elastically) without breaking..
Fatigue Resistance: Polypropylene retains its shape after a lot of torsion, bending, and/or flexing. This property is especially valuable for making living hinges.
Insulation: polypropylene has a very high resistance to electricity and is very useful for electronic components.
Transmissivity: Although Polypropylene can be made transparent, it is normally produced to be naturally opaque in color. Polypropylene can be used for applications where some transfer of light is important or where it is of aesthetic value. If high transmissivity is desired then plastics like Acrylic or Polycarbonate are better choices.

Polypropylene is classified as a “thermoplastic” (as opposed to “thermoset”) material which has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (roughly 130 degrees Celsius in the case of polypropylene). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics like polypropylene liquefy, which allows them to be easily injection molded and then subsequently recycled. By contrast, thermoset plastics can only be heated once (typically during the injection molding process). The first heating causes thermoset materials to set (similar to a 2-part epoxy) resulting in a chemical change that cannot be reversed. If you tried to heat a thermoset plastic to a high temperature a second time it would simply burn. This characteristic makes thermoset materials poor candidates for recycling.

Properties and Meaning of Fiberglass Reinforced Glass GFRP FiberGlass Vinyl Resin Food Grade

What is| FibreGlass Definition

fiberglassFiberglass products. It is translated from the term Fiberglass Reinforced Plastic or Glass Reinforced Composite, or plastic products with other materials to strengthen it. (There are more than 2 materials to join together) The material used to reinforce the plastic is “glass fiber”, which is soft but tough. High heat resistance As for the plastic that is used as meat It must be a very hard type. Which without reinforcement then becomes brittle Therefore, we choose to remove the plastic type Polyester resin Vinyl Esther Resin And epoxy resin This type of plastic is a liquid plastic which after mixing with Catalyst or hardening agent will then undergo a chemical reaction. It is heated above 100? C. It will turn into hard plastic and will not return to form again, which is called a process. Thermosetting (Thermoseting) A

factory, grating, sump cap, pipe cover, drain grate, grating manhole, so the product is created by the above method. Therefore can be called Glass fiber reinforced plastic products or FRP, which we simply call fiberglass products or FRP products.

Fiberglass or glass fibers can be classified into two types according to their characteristics. Is a continuous filament similar to a thread That can be woven into a fabric (fiberglass fabric) fabric that will not absorb water, do not shrink, and prevent heat well. Most of them will be used in industrial applications such as fire protection curtains. The other type of fiber is short, intermittent fibers. Often used as a heat insulation and sound insulation, which is characterized by a soft thick sheet.

The main ingredients used to produce glass fibers are silica sand, used to create glass, soda ash and limestone, the latter two to help reduce the melting point. In addition to the three main ingredients, there may be other ingredients used to improve the properties of glass fibers, such as borax, feldspar, calcined alumina, magnesite, nepheline. Cyanite (nepheline syenite) and kaolin clay (kaolin clay)

Definition of polyester resin

any of various synthetic resins or plastics consisting of or made from polyesters: such as a resin that has the same chemical composition as the common polyester fiber but that is extruded as a film (as for use in packaging, as electrical insulation, or as a base for magnetic recording tapes) c: a thermosetting resin that is made from an unsaturated polyester (as one formed from a glycol and maleic acid or fumaric acid. ), cured by copolymerization (as with styrene), and often reinforced with fillers (as glass fibers) and that is used chiefly in impregnating and laminating and in making cast and molded products

For the thermal insulation material sometimes called fiberglass, see glass wool. For the glass f iber itself, also sometimes called fiberglass, see glass fiber. For similar composite materials in which the reinforcement fiber is carbon fibers, see carbon-fiber-reinforced polymer. Fiberglass (or fibreglass) is a type of fiber-reinforced plastic where the reinforcement fiber. is specifically glass fiber. The glass fiber may be randomly arranged, flattened into a sheet (called a chopped strand mat), or woven into a fabric. The plastic matrix may be a thermosetting plastic – most often epoxy, polyester resin – or vinylester, or a thermoplastic.

The glass fibers are made of various types of glass depending upon the fiberglass use. These glasses all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes boron. To be used in fiberglass, glass fibers have to be made with very low levels of defects.Fiberglass

is a strong lightweight material and is used for many products.Although it is not as strong and stiff as composites based on carbon fiber, it is less brittle, and its raw materials are much cheaper. Its bulk strength and weight are also better than many metals, and it can be more readily molded into complex shapes. Applications of fiberglass include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, casts, surfboards, and external door skins.

Other common names for fiberglass are glass-reinforced plastic (GRP), [1] glass-fiber reinforced plastic ( GFRP) [2] or GFK (from German: Glasfaserverst? Rkter Kunststoff). Because glass fiber itself is sometimes referred to as “fiberglass”, the composite is also called “fiberglass reinforced plastic.” This article will adopt the convention that “fiberglass “refers to the complete glass fiber reinforced composite material, rather than only to the glass fiber within it.

  

From about fiberglass | History of FRP FibreGlass

Some people know “fiberglass” as a composite material. Or reinforced plastics It is used to produce the roof for pickup trucks or bathtubs. But actually “Fiberglass” is “glass fiber” with a literal meaning. Glass fibers are used as reinforcing materials for plastic resins and molded into products such as truck roofs, bathtubs, boats, small aircraft parts, water tanks. Big racing car parts Glass reinforced concrete products (Glass Reinforced Concrete, GRC) etc. In addition to strength properties It can withstand very high tensile strength. Glass fibers also have Heat insulation Used as insulation in stoves, refrigerators, or building materials. In addition, glass fibers can be woven into fabric, sewn into pieces and with a structure that makes The product is made of Optical fibers have gaps within them. That is trapped, making it capable of preventing heat as well Suitable to make a cloth as a backing. For good insulation as you would for a refrigerator or a winter jacket. Glass fiber fabric does not absorb water. Use as a waterproof cloth No shrinkage and no wasted effect from water.

Glass fibers are available in various sizes and lengths. The fibers can be as long as threads. Extremely long to very short fibers that cannot be seen with the naked eye. Glass fibers are made from a mixture of sand, limestone, horse tooth, boric acid and other additives. Smelt inside Electric stoves at very high temperatures up to 1370 degrees Celsius, which, if well controlled, ingredients are purity. There is no need to make a crystal ball to select a good crystal ball. To melt into new glass water again, after which it will go into the process of rolling into long fibers With fibers being removed from the extruder head And is coiled at a higher speed than that of glass fiber. Extruded from the extruder head Which is equal to stretching while the fibers are still soft Get fiber size Smaller before erection This long fiber is often used to make curtains. If you want to make a short fiber. Will be cut by the wind to a different length Which is commonly used to make tapes or cloth products In industry To protect the sound Temperature and fire

“Fiberglass” in the language of commonly known reinforcing materials. In making the pickup roof Or parts that require that strength It is produced from the use of prototype parts to be polished on the outside surface as well. Replica wax Place the fiberglass cloth on the prototype piece. It is applied with a resin that has been hardened to the desired thickness. Once the resin has hardened, the fiberglass part is removed from the prototype and polished to finish the exterior finish The fiberglass part construction from this method lacks detail and aesthetics unlike the method used by mold. This is ideal for a large number of parts, but is a more difficult step than the first method. We have to build a mold from prototype parts first. When the mold And then used to create the desired fiberglass parts The crafted pieces are as beautiful as Prototype in all respects And can strengthen the desired area by increasing the thickness Of many layers of glass fibers

Fiberglass is made from many chemicals and materials. This is dangerous to health such as eyes, skin, respiratory system, so be careful and wear protective equipment when making fiberglass parts.

Grating manhole: Glass fibers have been produced for centuries, but mass production of glass strands was accidentally discovered in 1932 when Games Slayter, a researcher at Owens-Illinois, directed a jet. of compressed air at a stream of molten glass and produced fibers. A patent for this method of producing glass wool was first applied for in 1933.Owens joined with the Corning company in 1935 and the method was adapted by Owens Corning to produce its patented. ” fibreglas “(one” s “) in 1936. Originally, fibreglas was a glass wool with fibers entrapping a great deal of gas, making it useful as an insulator, especially at high temperatures.

A suitable resin for combining the” fiberglass “with a plastic to produce a composite material was developed in 1936 by du Pont. The first ancestor of modern polyester resins is Cyanamid’s resin of 1942. Peroxide curing systems were used by then. With the combination of fiberglass and resin the gas content. of the material was replaced by plastic. This reduced the insulation properties to values ​​typical of the plastic, but now for the first time the composite showed great strength and promise as a structural and building material. Confusingly, many glass fiber composites continued to be called “fiberglass” (as a generic name) and the name was also used for the low-density glass wool product containing gas instead of plastic.

Ray Greene of Owens Corning is credited with producing the first composite boat in 1937, but did not proceed further. at the time due to the brittle nature of the plastic used. In 1939 Russia was reported to have constructed a passenger boat of plastic materials, and the United States a fuselage and wings of an aircraft. The first car to have a fiber-glass body was a 1946 prototype of the Stout Scarab, but the model did not enter production. Production

melting all ingredients. In an electric stove at high temperatures up to 1370 degrees Celsius to obtain glass water. The fibers are then extracted from the extrusion head and rolled up at a speed higher than the speed of the extruding glass fibers. This equates to stretching while the fibers are still soft, resulting in smaller fibers before coagulation.

If you want to make a short fiber, you can cut it by wind. Can make fibers of different lengths,

however, in the melting process If there is no quality control of the ingredients to be purified, then it is necessary to heat and refine the glass water into glass beads first so that the pure glass is re-melted into glass water again. But if the quality of the ingredients is controlled Then can iron the fibers from the glass water in the stove

The “fiberglass” in the meaning of the reinforcing material. It can be produced in two ways. First, the prototype parts are polished to the exterior with wax removing. Place the fiberglass cloth on the prototype piece. It is applied with a resin that is mixed with a stiffener to the desired thickness. Once the resin has hardened, the fiberglass part is removed from the prototype. To be polished to finish the outer surface to be complete Fabricating fiberglass parts this way lacks detail and aesthetics, unlike the second method that is molded. This method is suitable for a large number of parts. But there is a more difficult step than the first method. We have to build a mold from prototype parts first. When the mold And then used to create the desired fiberglass parts The crafted pieces are as beautiful as the prototype in all respects. And can be reinforced in specific areas by increasing the thickness of the glass fiber multi-layered

The process of manufacturing fiberglass is called pultrusion, limestone, kaolin clay, fluorspar, colemanite, dolomite and other minerals to liquid form. It is then extruded through bushings, which are bundles of very small orifices (typically 5–25 micrometres in diameter for E-Glass, 9 micrometres for S- Glass). These filaments are then sized (coated) with a chemical solution. The individual filaments are now bundled in large numbers to provide a roving. The diameter of the filaments, and the number of filaments in the roving, determine its weight, typically. expressed in one of two measurement systems: yield, or yards per pound (the number of yards of fiber in one pound of material; thus a smaller number means a heavier roving). Examples of standard yields are 225yield, 450yield, 675yield.tex, or grams per km (how many grams 1 km of roving weighs, inverted from yield; thus a smaller number means a lighter roving). Examples of standard tex are 750tex, 1100tex, 2200tex.

These rovings are then either used directly in a composite application such as pultrusion, filament winding (pipe), gun roving (where an automated gun chops the glass into short lengths and drops it into a jet of resin, projected onto the surface of a mold), or in an. intermediary step, to manufacture fabrics such as chopped strand mat (CSM) (made of randomly oriented small cut lengths of fiber all bonded together), woven fabrics, knit fabrics or uni-directional fabrics. Chopped strand mat

Chopped strand mat or CSM is a form of reinforcement used in fiberglass.It consists of glass fibers laid randomly across each other and held together by a binder.It

is typically processed using the hand lay-up technique, where sheets of material are placed in a mold and brushed with resin. Because th e binder dissolves in resin, the material easily conforms to different shapes when wetted out. After the resin cures, the hardened product can be taken from the mold and finished. Using chopped strand mat gives a fiberglass with isotropic in-plane material properties.

An individual structural glass fiber is both stiff and strong in tension and compression — that is, along its axis. Although it might be assumed that the fiber is weak in compression, it is actually only the long aspect ratio. of the fiber which makes it seem so; ie, because a typical fiber is long and narrow, it buckles easily. [7] On the other hand, the glass fiber is weak in shear — that is, across its axis. Therefore, if a collection of fibers can be arranged permanently in a preferred direction within a material, and if they can be prevented from buckling in compression, the material will be preferentially strong in that direction.

Furthermore, by laying multiple layers of fiber on top of one another , with each layer oriented in various preferred directions, the material’s overall stiffness and strength can be efficiently controlled. In fiberglass, it is the plastic matrix which permanently constrains the structural glass fibers to directions chosen by the designer. . With chopped strand mat, this directionality is essentially an entire two dimensional plane; with woven fabrics or unidirectional layers, directionality of stiffness and strength can be more precisely controlled within the plane.

A fiberglass component is typically of a thin “shell” construction, sometimes filled on the inside with structural foam, as in the case of surfboards. The component may be of nearly arbitrary shape, limited only by the complexity and tolerances of the mold used for manufacturing the shell.

The mechanical functionality of materials is heavily relied on the combined performances of both the resin (AKA matrix) and fibers. For example, in severe temperature condition (over 180? C) resin component of the composite may lose its functionality partially because of bond deterioration of resin and fiber. [8] However , GFRPs can show still significant residual strength after experiencing high temperature (200? C).

Composite (GFRP) Gratings: What is GFRP (Glass Fiber Reinforced Plastic)? GFRP is a composite material made of a polymer matrix reinforced with fiber, aiming to form better physical and chemical properties. GFRP i sa production material such as metal, wood, glass, concrete. GFRP materials has important advantages as against other production materials, new features can be acquired according to requirements. What is GFRP Grating? Molded GFRP gratings are produced in special molds with wet lamination process , consist of glass fiber, resin, additives and pigment. After these raw materials harden, GFRP gratings are pressed out of the mold. Molded GFRP gratings are light, anti-corrosive, have high chemical and physical resistances and electrically non-conductive. Components : Resin, glass fiber, additives and pigment are the basic components of the GFRP materials. It can be produced any material which are proper for the requirements by changing these components. Resin: Chemical resistance, flexibility and UV resistance of the GFRP gratings are determined. by the resin. Resins are chose according to the environment; orthophthalic resin for general usage, isophthalic resin for chemical environment and vi nyl ester resin for extremely heavy chemical environment. Glass Fiber: Multi-layered continuous glass fibers are used in production. Molded GFRP gratings have high mechanical resistance due to glass fiber. Additives: Additives such as UV stabilizers, flame retardants and low smoke density retardants. increase mechanical and chemical resistance and add new superior features. Pigment: Pigments make it possible to give the GFRP gratings any color. This makes it happen to use GFRP gratings in architectural projects.

Fiber-reinforced plastic (FRP) (also called fiber-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass, carbon, aramid, or basalt. Rarely, other fibers such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinylester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.

FRPs are commonly used in the aerospace, automotive , m arine, and construction industries. They are commonly found in ballistic armor as well.

A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers the. result is referred to as a plastic. Composite plastics refer to those types of plastics that result from bonding two or more homogeneous materials with different material properties to derive a final product with certain desired material and mechanical properties. Fiber-reinforced plastics are a category of composite plastics that specifically use fiber materials to mechanically enhance the strength and elasticity of plastics. The original plastic material without fiber reinforcement is known as the matrix or binding agent. The matrix is ​​a tough but relatively weak plastic that is reinforced by stronger stiffer reinforcing filaments. or fibers.The extent that strength and elasticity are enhanced in a fib re-reinforced plastic depends on the mechanical properties of both the fiber and matrix, their volume relative to one another, and the fiber length and orientation within the matrix. [1] Reinforcement of the matrix occurs by definition when the FRP material exhibits increased. strength or elasticity relative to the strength and elasticity of the matrix alone.

FRP can be applied to strengthen the beams, columns, and slabs of buildings and bridges. It is possible to increase the strength of structural members even after they have been severely damaged due. to loading conditions. In the case of damaged reinforced concrete members, this would first require the repair of the member by removing loose debris and filling in cavities and cracks with mortar or epoxy resin. Once the member is repaired, strengthening can be achieved through wet. , hand lay-up of impregnating the fiber sheets with epoxy resin then applying them to the cleaned and prepared surfaces of the member. Two techniques are typic ally adopted for the strengthening of beams, relating to the strength enhancement desired: flexural strengthening or shear strengthening. In many cases it may be necessary to provide both strength enhancements. For the flexural strengthening of a beam, FRP sheets or plates are applied to the tension face of the member (the bottom face for a simply supported member with applied top loading or gravity loading). Principal tensile fibers are oriented in the beam longitudinal axis, similar to its internal flexural steel reinforcement. This increases the beam strength and its stiffness (load required to cause unit deflection), however decreases the deflection capacity and ductility. For the shear strengthening of a beam, the FRP is applied on the web (sides) of a member with fibers oriented transverse to the beam’s longitudinal axis. Resisting. of shear forces is achieved in a similar manner as internal steel stirrups, by bridging shear cracks that form under applied loading. FRP can be appli ed in several configurations, depending on the exposed faces of the member and the degree of strengthening desired, this includes: side bonding, U-wraps (U-jackets), and closed wraps (complete wraps). Side bonding involves applying FRP to the sides of the beam only. It provides the least amount of shear strengthening due to failures caused by de-bonding from the concrete surface at the FRP free edges. For U-wraps, the FRP is applied continuously in a ‘U’ shape around. the sides and bottom (tension) face of the beam. If all faces of a beam are accessible, the use of closed wraps is desirable as they provide the most strength enhancement. Closed wrapping involves applying FRP around the entire perimeter of the member, such that there are no free ends and the typical failure mode is rupture of the fibers. For all wrap configurations, the FRP can be applied along the length of the member as a continuous sheet or as discrete strips, having a predefined minimum width and spacing. Slabs may be strengthened by applying FRP strips at their bottom (tension) face. This will result in better flexural performance, since the tensile resistance of the slabs is supplemented by the tensile strength of FRP. In the case of beams and slabs, the effectiveness of FRP strengthening depends on the performance of the resin chosen for bonding. This is particularly an issue for shear strengthening using side bonding or U-wraps. Columns are typically wrapped with FRP around their perimeter, as with closed or complete wrapping. This not only results. in higher shear resistance, but more crucial for column design, it results in increased compressive strength under axial loading. The FRP wrap works by restraining the lateral expansion of the column, which can enhance confinement in a similar manner as spiral reinforcement does for the column. core.

Applications of Fiber Glass Grating Grating manhole

A cryostat made of fiberglass Fiberglass is an immensely versatile material due to its light weight, inherent strength, weather-resistant finish and variety of surface textures.

The development of fiber-reinforced plastic for commercial use was extensively researched in the 1930s. It was of particular interest to the aviation industry. . A means of mass production of glass strands was accidentally discovered in 1932 when a researcher at Owens-Illinois directed a jet of compressed air at a stream of molten glass and p roduced fibers. After Owens merged with the Corning company in 1935, Owens Corning adapted the method to produce its patented “Fiberglas” (one “s”). A suitable resin for combining the “Fiberglas” with a plastic was developed in 1936 by du Pont. The first ancestor of modern polyester resins is Cyanamid’s of 1942. Peroxide curing systems were used by then. During World War II, fiberglass was developed as a replacement for the molded plywood used in aircraft radomes (fiberglass being transparent to microwaves). Its first main civilian application was for the building of boats and sports car bodies, where it gained acceptance in the 1950s. Its use has broadened to the automotive and sport equipment sectors. In production of some products, such as aircraft, carbon fiber is now used instead of fiberglass, which is stronger by volume and weight. Advanced manufacturing techniques such as pre-pregs and fiber rovings extend fiberglass’s applications and the tensile strength possible with fiber-r einforced plastics.

Fiberglass is also used in the telecommunications industry for shrouding antennas, due to its RF permeability and low signal attenuation properties. It may also be used to conceal other equipment where no signal permeability is required, such as equipment cabinets and steel support structures, due to the ease with which it can be molded and painted to blend with existing structures and surfaces. Other uses include sheet-form electrical insulators and structural components commonly found in power-industry products. Because of fiberglass’s light weight and durability, it is often used in protective equipment such as helmets. Many sports use fiberglass protective gear, such as goaltenders’ and catchers’ masks.

Storage tanks

Several large fiberglass tanks at an airport Storage tanks can be made of fiberglass with capacities up to about 300 tonnes. Smaller tanks can be made with chopped strand mat cast over a thermoplastic inner tank which acts as a preform during constr uction. Much more reliable tanks are made using woven mat or filament wound fiber, with the fiber orientation at right angles to the hoop stress imposed in the side wall by the contents. Such tanks tend to be used for chemical storage because the plastic liner (often polypropylene) is resistant to a wide range of corrosive chemicals. Fiberglass is also used for septic tanks.

House building

Glass-reinforced plastics are also used to produce house building components such as roofing laminate, door surrounds, over-door canopies, window canopies and dormers, chimneys, coping systems, and heads with keystones and sills. The material’s reduced weight and easier handling, compared to wood or metal, allows faster installation. Mass-produced fiberglass brick-effect panels can be used in the construction of composite housing, and can include insulation to reduce heat loss.

Some surfaces like tile and laminate are prone to becoming extremely slippery when moist. Accidents that occur as a result of a misplaced foot can be embarrassing, painful, and very costly. It is always a good idea to have anti-slip floor mats set in place, especially in an area prone to wet conditions. Rubber-Cal’s line of safety flooring mats is an ideal and affordable solution to safeguarding your area from the dangers of moisture while making sure that you and your guests are secure on your feet. A huge part of this safety lies in the rubber material used to make our anti-skid flooring. It enhances traction and inhibits moisture at the same time. Every type of floor, whether it is residential, commercial, or industrial, can benefi t from the prese nce of rubber traction mats. The primary feature about anti-slip floor mats is that they increase the safety of wet areas. Business owners take an interest in rubber non-slip mats because of this reason. Some commercial venues like restaurant kitchens are hazardous areas that see lots of loose liquids getting onto their existing floors. Without any safety flooring in place, the risk of workers slipping and injuring themselves is far greater. In addition to kitchen areas, these mats are ideal to place at entryways when there are wet weather conditions. With rubber anti-slip floor mats placed in such areas, people will experience more security while on their feet. This safety is provided in large part thanks to the rubber material that is used in our traction mats.

Fiberglass.

Types of glass fiber used Main article: Glass fiber Composition: the most common types of glass fiber used in fiberglass is E- glass, which is alumino-borosilicate glass with less than 1% w / w alkali oxides, mainly used for glass-reinforced plastics. Other types of glass used are A-glass (Alkali-lime glass with little or no boron oxide), E -CR-glass (Electrical / Chemical Resistance; alumino-lime silicate with less than 1% w / w alkali oxides, with high acid resistance), C-glass (alkali-lime glass with high boron oxide content, used for glass staple fibers and insulation), D-glass (borosilicate glass, named for its low Dielectric constant), R-glass (alumino silicate glass without MgO and CaO with high mechanical requirements as Reinforcement), and S-glass (alumino silicate glass without CaO but with. high MgO content with high tensile strength) Naming and use: pure silica (silicon dioxide), when cooled as fuse. d quartz into a glass with no true melting point, can be used as a glass fiber for fiberglass, but has the drawback that it must be worked at very high temperatures. In order to lower the necessary work temperature, other materials are introduced as ” fluxing agents “(ie, components to lower the melting point). Ordinary A-glass (” A “for” alkali-lime “) or soda lime glass, crushed and ready to be remelted, as so-called cullet glass, was the first type of glass used for fiberglass. E-glass (“E” because of initial Electrical application), is alkali free, and was the first glass formulation used for continuous filament formation.It now makes up most of the fiberglass production in the world , and also is the single largest consumer of boron minerals globally. It is susceptible to chloride ion attack and is a poor choice for marine applications. S-glass (“S” for “stiff”) is used when tensile strength (high modulus) is important, and is thus an important building and aircraft epoxy composite (it is called R-glass, “R” for “reinforcement” in Europe). C-glass (“C” for “chemical resistance”) and T-glass (“T” is for “thermal insulator” —a North American. variant of C-glass) are resistant to chemical attack; both are often found in insulation-grades of blown fiberglass. It is the main raw material used in fiberglass molding. Generally, glass fibers are classified into different types according to the following properties:

1. Type A glass (Alkali) is used for applications requiring resistance to alkaline chemicals.

2. Type C glass (Chemical) is used for applications that require chemical resistance. That is acidic and corrosive.

3. Type E glass (Electrical is used for applications that require strength and a good electrical insulation.

4. Type S glass (High Strength) is used for applications that require higher loads than Type E. glass

Glass fibers are divided into the following types:

1. Chopped strands mat, short fiber glass fibers, approximately 1-2 inches long, sprinkled onto a dispersed patch by bonding glue (binder), there are two types:

• Emultion type is a flat, tight sheet suitable for work that requires constant smoothness. Does not move.

• Powder is a loose woven fiber sheet. Suitable for jobs that need to enter a niche There are many corners and niches. Size called by weight per square meter, there are sizes 100, 200, 300, 450, 600 and 900 grams / square meter. Used for general

fiberglass applications. 2. Woven roving is a short glass fiber woven into a woven mesh with sizes 400, 600, 800, 900, 1,000 and 1,200 grams / square meter. Strengthen it higher In the direction of glass fibers (2 directions)

3. Glass cloth, woven glass fibers, thread-like fibers woven into a dense fabric, size 30, 60, 90, 100, 160, 200 and 300 g / square meter. Help to get strength well. Able to do thin and light workpieces Used to strengthen the edges of the workpiece And the top and bottom surface of the work.

4. Stitch mat, a chopped strand mat, sewn with polyester fibers. When put into use, the fiberglass will not move. Makes a work piece that is strong and complete power, size 300, 450, 600 and 900 g / square meter.

5. Fiberglass surface (Surfacing mat) is a thin piece of glass fiber like tissue paper. Size, weight 20 30 50 g / square meter. Helps to strengthen the adhesion of the gel coat layer. And reduce the amount of air bubbles of the gel-coat layer with glass fibers.

6. Glass tape is a fiber tape, woven into a piece of 2 inches, 3 inches, 4 inches wide, used for connecting the joints between the glass fiber sheets. And reinforcing the edge of the workpiece.

7. Fiberglass yarn (Roving) is a long glass fiber throughout the roll. Called by weight / length of 1 km, for example, TEX1200 = 1 km length, 1 kg weight, popularly used size 1200 2200 2400 4800 etc. Divided by the following usage characteristics

• Spray (spray up roving) used with a spray machine. Glass fiber is commonly used number 2400

Polyester resin

It is a kind of liquid plastic. It looks thick like engine oil. The pungent smell hardens with high heat. Is a type of flammable substance Has a shrinkage rate of 2-8% after the full set. Resins can be molded into a wide variety of applications. Resin for casting general works, casting monks, casting souvenirs Casting dolls, etc. Resin for fiberglass casting And resin for coating work such as science frame coating While casting Resin releases a chemical odor which has a pungent odor. Therefore, the workplace should be well-ventilated. Should not work in a place that is a solid room. And there is not enough air flow or ventilation.

Resins are classified according to the grades of their properties:

1. ortho-phthalic type is a commonly used

grade 2. isophthalic type is acid-alkaline resistant type

3. bisphenol type is an acid-resistant type. – alkaline high

grade 4. chlorendics type of acid – basehigh-grade

5.  vinyl ester is resistant acid – base very strong, second only to qualified epoxy resin

as a resin extract the meat into 2 types:

1. nonpromote the race. Resin that has not mixed with catalyst. The nature of the resin will be a thick oil like oil. Have a yellowish clear color The highlight is the shelf life of 3 months (for Thailand, which is hot and humid, should be used within 1 month because when entering the 2nd and 3rd months The resin will begin to have a thicker viscosity), and many more formulations can be applied. To suit various forms of work Non-promote polyester resin type

2. promote is a type of resin that is mixed with catalysts. The nature of the resin is a slurry like engine oil. But fuchsia pink because it is a resin that has been mixed with catalyst When used, just add the accelerator. In terms of color resins, some manufacturers may use different accelerators, so some resins with water like grass jelly have a darker color. And for the type that is used with clear casting, the resin will have color Light bluish clear The advantage is that it is easy to use and fluent without difficulty, but the disadvantage is that it has a short shelf life. Shelf life not more than 2 months in actual use should be used within 1 month

Properties of polyester resin

Resins are cast plastics with physical, electrical and chemical

properties. It has the properties of hard, clear, shiny, resistant to high temperatures better than thermoplastic plastics (termoplastic), but less than metal. When reinforced with glass fibers Will get more strength, light weight, strong toughness, not brittle, electrical properties Resin has complete electrical properties. It can be used as an insulator (insulator).

Usage characteristics of polyester resin.

Resin can be used in many applications. But divided into 3 large groups that are commonly used in our home, including:

1. The casting (casting), such as casting Buddha images, casting gifts, casting buttons, artificial glass casting, etc.

2. The coating (laminate), such as coating work. Science frame

3. Molding work groups such as fiberglass fabrication or FRP (fiberglass reinforce plastic), glass fiber reinforced plastics.

Solidification of resin

The polyester resin can be cured in several ways:

1. By using a catalyst or a hardening+ heat

agent2. by using a catalyst or a hardening agent + catalyst. promote / accelerator At room temperature

3. Using ultraviolet light

4. Using electrons

5. Using sunlight

6. Using heat

In general, the solidification of the resin is divided into two periods: 1. gel time is the period after the catalyst is added until the resin coagulates. Phase 2. cure time is the period when the resin is fully cured and the period when the catalyst is added. The resin cools after being heated during the reaction.

Elements affecting the hardening of the resin

1. At high temperature, the resin hardens faster than the low temperature

2. The large quantity of accelerator and the accelerator hardens faster than the small amount

3. Moisture or water The high humidity, the coagulation of the resin slows down. The work surface is hazy. Normally, the water content in the resin must not exceed 0.05%.

4. Oxygen content. Oxygen is a resin antifreeze. If the oxygen content is high Such as stirring the resin for a long time, the solidification of the resin will slow down. And oxygen is very useful in extending the shelf life of the resin. If starting to store resin for longer Should generate oxygen in the tank. Or peep by rolling the barrel back and forth To allow the resin inside to move Will produce oxygen And will cause the resin to have a slightly longer shelf life

Innovative synthetic materials

1. Plastic (Plastic) 2. Composites (Composite) 3. Kevlar “Kevlar” 4. Carbon Fibers (Carbon Fibers) 5. Polyurethane foam. (Polyurethane Foam) 6. ABS (Acrylonitrile-Butadiene-Styrene) 7. Polypropylene (PP) Plastic

1. What is plastic? (Factory manufacturers grating the pond lid, pipe cover, drain grate, grating manhole)

plastic is a kind of synthetic material. Which has a very broad meaning (Like the word life Plastic is a synthetic material known to mankind for more than 130 years and is used as a substitute for metal, wood or other natural materials such as textiles, boats and packaging materials. Including many other equipment and appliances Plastics are materials that synthesize naturally derived raw materials such as petroleum. To separate into compounds Many kinds of pure When taking each compound The reaction type will result in “plastic”. Plastics formed from different compounds will have different properties as well.

Types of plastics

1. Thermoplastic (Soft plastic) Soft

plastic, when heated, will soften, melt. And while cooling, it becomes stiff This plastic can be fused back and used again. Therefore, scrap or used items made from this type of plastic can be crushed and reused, such as polyethelene, polypropylene, polyvinyl chloride. (Polyvinyl Chloride), etc.

2. Thermoseting (hard)

plastichard plastic when heated and not softening. But will be scorched This kind of plastic product. When extruded or mixed for use, it cannot be melted again. Therefore, scrap or used items that will make this type of plastic. Therefore cannot be crushed and used again Due to solidification causing the plastic to undergo chemical changes This plastic is made from soft plastic. By adding a catalyst called Hardener to soft plastic. Will immediately harden the meat It has relatively high strength, such as melamine, formaldehyde (Melamine Formaldehyde), phenolic (Phenolic), polyester (Polyester) well known as polyester in the form of fiberglass products. Polyurethane (Urethane) E-Fox (Epoxy)

2. What is composite (Composite)?

Composite is the name for a product that contains a material. Two or more Come together or collaborate To use the salient properties of each material Examples of composite materials Clearly understood are tires, which are made up of two main materials: rubber and steel wire. By using the properties of steel strength and elasticity of rubber for softness Which could not be used in any way Or, but not good, for example, if using only iron, it will not be soft. Or use only rubber, it will have a lot of weight And not strong Reinforced concrete is another example of its outstanding properties. Concrete in terms of compressive strength and low cost, durable, easy to find, with outstanding steel, both compressive and tensile, but the price is high and Highly serviceable due to being easily rusted

Many people know fiberglass. Whether it is a composite material or a reinforced plastic Like fiber-reinforced plastics (fiber-reinforced plastic, FRP) or glass-reinforced plastic (glass-reinforced plastic, GRP), but actually fiberglass is a fiber of glass that spun into a thin fine line. To be used as a reinforcing material in many types of polymers. Including plastic resins that can be molded into products such as pickup truck roofs, bathtubs, boats, small aircraft parts. Large water tank Racing car parts, etc., because glass fibers have strength properties High tensile strength, never rust and corrosion resistance.

In addition, glass fibers have good insulating properties and are suitable for insulation in stoves, refrigerators or building materials.

3. Kevlar “Kevlar”

is an aramid type of fiber discovered by Stephanie Kwolek, a company. DuPont in the year 1971 (1971) with synthesis Based on the condensation action of terephthaloylchloride (TPC) acid chloride (TPC) and p-phenylene diamine (PDA), Kevlar fibers are often used in industrial applications. In the case of long fibers, Kevlar is used to make canvas, tires, pipes and belts in the industrial industry.Kevlar 29 is also in the form of long fibers used to make cables, parachutes, and Kevlar reinforcement tapes. LAR 49 in the form of long and short strands of sheets. Mainly used in the fields of fiber-reinforced plastics, aerospace, hull and related construction applications. It has good resistance to high temperatures. And excelling in strength Which can withstand heat up to 427 degrees Celsius, 7 times more resistant than steel, but not resistant to abrasion And inflexible Fragile When being bended strongly.

4. Carbon Fibers

are classified as composites. And the properties change according to the nature of production The basic structure is characterized by a very small single fiber. The strength in the fibers is very high. Higher than metals of the same weight When the carbon fiber is aligned fiber in the same direction. Using epoxy resin as a binder You will get a material that looks like a plank that we can tear apart in the wood burr. But cannot interrupt the line of the web To use carbon fibers it is necessary to weave them in such a way that the fibers are crossed or crossed like a plywood board. Thus making it possible to maintain a strong line of strength The design must therefore be suitable for the nature of use and the load line is important. For the adoption of carbon fiber The production has to take into account the nature of their use is important. The strength of carbon fiber materials, such as tubes and discs, is stronger than metal. It can therefore be made lighter while still being stronger than metals of the same size. The service life of carbon fiber is very durable. The strength or durability of carbon fibers is partly due to epoxy resin that is a binder between the fibers and between layers.

5. Polyurethane foam. (Polyurethane Foam)

is a liquid plastic thermosetting type. (Thermosetting) that is commonly used in artificial work, such as imitation of artificial wood. (The size of the foam beads is very small) to make a car bumper. Interior components such as steering wheel and console panels, prosthetics and mold strengthening (larger foam beads), as well as cold storage insulators. There are two typesliquids.

ofType 1 is yellowish like polyester resin, called white foam or polyol.

Type 2 is almost burnt brown, called foam black or diI. Socyanate (diisocyanate)

Polyurethane is a group of polymers. Widely used because It is an elastic material Soft to strong materials And lightweight polyurethane is divided into three groups:

– Flexible polyurethane foam (flexible polyurethane foam)

– polyurethane rigid polyurethane foam (rigid polyurethane foam)

– electronic. Lastomers (polyurethane elastomers)

6. ABS (Acrylonitrile-Butadiene-Styrene)

ABS is a low cost engineering plastic that is easy to machine and fabricate. ABS is an ideal material for structural applications when impact resistance, strength, and stiffness are required. It is widely used for machining pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue. Natural (beige) ABS and black ABS are FDA compliant for use in food processing applications. The following physical property information is based on typical values ​​of the base acrylonitrile-butadiene-styrene resin.

ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40. to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly (styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The polybutadiene, a rubbery substance, provides toughness even at low temperatures. For the majority of applications, ABS can be used between -20 and 80 C (-4 and 176 F) as its mechanical properties vary with temperature.The properties are created by rubber toughening, where fine particles of elastomer are distributed throughout the rigid matrix.The

most important mechanical properties of ABS are impact resistance and toughness. A variety of modifications can be made to improve impact resistance, toughness , and heat resistance. The impact resistance can be amplified by increasing the proportions of polybutadiene in relation to styrene and also acrylonitrile, although this cause s changes in other properties. Impact resistance does not fall off rapidly at lower temperatures. Stability under load is excellent with limited loads. Thus, by changing the proportions of its components, ABS can be prepared in different grades. Two major categories could be ABS for extrusion and ABS for injection molding, then high and medium impact resistance. Generally ABS would have useful characteristics within a temperature range from? 20 to 80 C (? 4 to 176 F). Lego bricks are made from ABS.

The final properties will be influenced to some extent by the conditions under which the material is processed to the final product. For example, molding at a high temperature improves the gloss and heat resistance of the product whereas the highest impact resistance and strength are obtained by molding at low temperature. Fibers (usually glass fibers) and additives can be mixed in the resin pellets to make the final product strong and raise the operating range to as high as 80 C (176 F). P i gments can also be added, as the raw material original color is translucent ivory to white. The aging characteristics of the polymers are largely influenced by the polybutadiene content, and it is normal to include antioxidants in the composition. Other factors include exposure to ultraviolet radiation, for which additives are also available to protect against.

ABS polymers are resistant to aqueous acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils, but they are swollen by glacial acetic acid, carbon tetrachloride and aromatic. hydrocarbons and are attacked by concentrated sulfuric and nitric acids. They are soluble in esters, ketones, ethylene dichloride and acetone. Even though ABS plastics are used largely for mechanical purposes, they also have electrical properties that are fairly constant over a wide range of frequencies. . These properties are little affected by temperature and atmospheric humidity in the acceptable op e ra ting range of temperatures.

ABS is flammable when it is exposed to high temperatures, such as those of a wood fire. It will melt and then boil, at which point the vapors burst into intense, hot flames. Since pure ABS contains no halogens, its combustion does not typically produce any persistent organic pollutants, and the most toxic products of its combustion or pyrolysis are carbon monoxide and hydrogen cyanide. ABS is also damaged by sunlight. This caused one of the most widespread and expensive automobile recalls in US. history due to the degradation of the seatbelt release buttons.

ABS can be recycled, although it is not accepted by all recycling facilities. Production

ABS is derived from acrylonitrile, butadiene, and styrene. Acrylonitrile is a synthetic monomer produced from propylene and ammonia; butadiene is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking; styrene monomer is made by dehydrogenation of ethyl benzene – a hydrocarbon obtained in the re. a ct ion of ethylene and benzene.

ABS combines the strength and rigidity of acrylonitrile and styrene polymers with the toughness of polybutadiene rubber. While the cost of producing ABS is roughly twice the cost of producing polystyrene, it is considered superior for its hardness, gloss. , toughness, and electrical insulation properties.

7. Polypropylene (PP) Plastic

What is Polypropylene (PP), and What is it Used For?

Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles. Polypropylene was first polymerized in 1951 by a pair of Phillips petroleum scientists named Paul Hogan and Robert. Banks and later by Italian and German scientists Natta and Rehn. It became prominent extremely fast, as commercial production began barely three years. af ter It alian chemist, Professor Giulio Natta, first polymerized it. Natta perfected and synthesized the first polypropylene resin in Spain in 1954, and the ability of polypropylene to crystallize created a lot of excitement. By 1957, its popularity had exploded and widespread commercial production began across Europe. Today it is one of the most commonly produced plastics in the world. CNC Cut Polypropylene Living Hinge Prototype Child Safe Lid, CNC Cut Polypropylene Living Hinge Prototype Child Safe Lid by Creative Mechanisms

According to some reports, the current global demand. for the material generates an annual market of about 45 million metric tons and it is estimated that the demand will rise to approximately 62 million metric tons by 2020.The major end users of polypropylene are the packaging industry, which consumes about 30% of the total , followed by the electrical and equipment manufacturing, which uses about 13% each. Household appliances and automotive industries both c ons ume 10% each and construction materials follows with 5% of the market. Other applications together make up the rest of the global polypropylene consumption.

Polypropylene has a relatively slippery surface which can make it a possible substitute for plastics like Acetal (POM) in. low friction applications like gears or for use as a contact point for furniture. Perhaps a negative aspect of this quality is that it can be difficult to bond Polypropylene to other surfaces (ie it does not adhere well to certain glues that work fine with other plastics and sometimes has to be welded in the event that forming a joint is required). Although polypropylene is slippery at the molecular level, it does have a relatively high coefficient of friction – which is why acetal, nylon, or PTFE would be used instead. Polypropylene also has a low density relative to other common plastics which translates to weight savings for manufacturers and distributors of injection molded Polypropylene parts. It has ex cept ion al r esistance at room temperature to organic solvents like fats but is subject to oxidation at higher temperatures (a potential issue during injection molding).

One of the major benefits of Polypropylene is that it can be manufactured (either through CNC or injection molding , thermoforming, or crimping) into a living hinge. Living hinges are extremely thin pieces of plastic that bend without breaking (even over extreme ranges of motion nearing 360 degrees). They are not particularly useful for structural applications like holding up a heavy door but are exceptionally useful for non load-bearing applications such as the lid on a bottle of ketchup or shampoo. Polypropylene is uniquely adept for living hinges because it does not break when repeatedly bent. One of the other advantages is that polypropylene can be CNC machined to include a living hinge which allows for faster prototype development and is less expensive than other prototyping methods. Creative Mechanisms is unique in ou r ab ility to machine living hinges from a single piece of polypropylene.

Another advantage of Polypropylene is that it can be easily copolymerized (essentially combined into a composite plastic) with other polymers like polyethylene. Copolymerization changes the material properties significantly, allowing for more robust engineering applications than are possible with pure polypropylene (more of a commodity plastic on its own).

The characteristics mentioned above and below mean that polypropylene is used in a variety of applications: dishwasher safe plates, trays, cups, etc, opaque to -go containers, and many toys.

What are the Characteristics of Polypropylene? Grating manhole

Some of the most significant properties of polypropylene are:

Chemical Resistance: Diluted bases and acids don’t react readily with polypropylene, which makes it a good choice for containers of such liquids, such as cleaning agents, first-aid products, and

more.Elasticity and Toughness: Polypropylene will act with elasticity over a certain range of deflection (like all materials), but it will also experience plastic deformation early on in the deformation process. , so it is generally considered a “tough” material. Toughness is an engineering term which is defined as a material’s ability to deform (plastically, not elastically) without breaking ..

Fatigue Resistance: Polypropylene retains its shape after a lot of torsion, bending , and / or flexing. This property is especially valuable for making living hinges.

Insulation: polypropylene has a very high resistance to electricity and is very useful for electronic components.

Transm issivity: Although Polypropylene can be made transparent, it is normally produced to be naturally opaque in color. Polypropylene can be used for applications where some transfer of light is important or where it is of aesthetic value. If high transmissivity is desired then plastics like Acrylic. or Polycarbonate are better choices.

Polypropylene is classified as a “thermoplastic” (as opposed to “thermoset”) material which has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (roughly 130 degrees Celsius in the case of polypropylene). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics like polypropylene liquefy, which allows them to be easily injection molded and then subsequently recycled. By contrast, thermoset plastics can only be heated once (typically during the injection molding proc e ss). The first heating causes thermoset materials to set (similar to a 2-part epoxy) resulting in a chemical change that cannot be reversed. If you tried to heat a thermoset plastic to a high temperature a second time it would simply burn . This characteristic makes thermoset materials poor candidates for recycling.

玻璃纤维增​​强玻璃纤维的性质和含义玻璃纤维乙烯基食品级

什么是|玻璃纤维定义

玻璃纤维玻璃纤维产品。它是从术语玻璃纤维增​​强塑料或玻璃增强复合材料,或带有其他材料的塑料产品来增强它的翻译而来的。 (有两种以上的材料可以连接在一起)用来增强塑料的材料是“玻璃纤维”,它柔软但坚韧。高耐热性至于用作肉的塑料它必须是非常难的类型。如果没有加固,那么它会变脆因此,我们选择去除塑料类型聚酯树脂乙烯基酯树脂和环氧树脂这种类型的塑料是液体塑料,与催化剂或硬化剂将发生化学反应。加热到100℃以上。它会变成坚硬的塑料,并且不会再次恢复成形,这称为过程。热固性(热定型)

工厂,格栅,集水槽盖,管盖,排水格栅,格栅人孔,因此可以通过上述方法制造产品。因此可以称为玻璃纤维增​​强塑料产品或FRP,我们简称为玻璃纤维产品或FRP产品。

玻璃纤维或玻璃纤维根据其特性可以分为两种。是类似于线的连续细丝吗可以将其编织成不吸水,不收缩,防热效果好的织物(玻璃纤维织物)。它们中的大多数将用于工业应用,例如防火窗帘。另一种类型的纤维是短的,断续的纤维。通常用作隔热和隔音材料,其特征是柔软的厚板。

用于生产玻璃纤维的主要成分是硅砂,用于制造玻璃,苏打灰和石灰石,后两种有助于降低熔点。除了三种主要成分外,还可以使用其他成分来改善玻璃纤维的性能,例如硼砂,长石,煅烧氧化铝,菱镁矿,霞石,蓝晶石(霞石正长岩)和高岭土。  

关于玻璃纤维| FRP玻璃纤维的历史

有人知道“玻璃纤维”是一种复合材料。或增强塑料它用于生产皮卡车或浴缸的屋顶。但实际上“玻璃纤维”是字面意义上的“玻璃纤维”,玻璃纤维被用作塑料树脂的增强材料,并模制成卡车顶棚,浴缸,船,小型飞机零件,水箱等产品。玻璃纤维增​​强混凝土制品(玻璃纤维增​​强混凝土,GRC)等它可以承受很高的拉伸强度。玻璃纤维也有绝热用作炉子,冰箱或建筑材料的隔热材料,此外,玻璃纤维还可以织成织物,缝成碎片,并且其结构该产品是由光纤内部有缝隙。被困住了,使其也能够防止热量适用于做布作为背衬。与冰箱或防寒外套一样,具有良好的绝缘性。玻璃纤维织物不吸水。用作防水布无收缩,无水分浪费;

玻璃纤维有各种尺寸和长度。纤维可以与线一样长。肉眼无法看到的极长至极短的纤维。玻璃纤维由沙子,石灰石,马齿,硼酸和其他添加剂的混合物制成。闻到里面电炉在高达1370摄氏度的极高温度下,如果控制得当,其成分就是纯净的。无需制作水晶球即可选择优质的水晶球。再次融化成新的玻璃水,然后将其卷成长纤维从挤出机头上取下纤维并且以比玻璃纤维更高的速度卷绕。从挤出机头挤出等于在纤维仍然柔软时进行拉伸获取纤维尺寸勃起前较小这种长纤维通常用于制造窗帘。如果要制作短纤维。将被风切成不同的长度通常用于制造胶带或布制品在行业中保护声音温度和火

用通常已知的增强材料来使用“玻璃纤维”。在制作皮卡车顶或需要这种强度的零件它是通过使用原型零件制成的,在外部进行抛光复制蜡将玻璃纤维布放在原型件上。它涂有已硬化至所需厚度的树脂,一旦树脂硬化,就将玻璃纤维零件从原型中移出并抛光,以抛光外表面。与模具使用的方法不同,这种方法的玻璃纤维零件构造缺乏细节和美观。这对于大量零件是理想的,但是比第一种方法更困难。我们必须首先从原型零件制造模具。当模具然后用于创建所需的玻璃纤维零件精心制作的作品就像各个方面的原型并可以通过增加厚度来增强所需区域在许多玻璃纤维层中,玻璃纤维

由许多化学物质和材料组成。这对眼睛,皮肤,呼吸系统等健康有害,因此在制造玻璃纤维零件时要小心并穿戴防护设备。

检修孔:玻璃纤维的生产已有数百年历史,但是在1932年,欧文斯-伊利诺伊州的研究人员Game Slayter将压缩空气射向熔融玻璃流并产生了纤维时,偶然发现了玻璃丝的大量生产。这种生产玻璃棉的方法的专利于1933年首次申请。欧文斯(Owens)于1935年加入了康宁公司,欧文斯·康宁(Owens Corning)对该方法进行了修改,于1936年生产了获得专利的“玻璃纤维”(一个)。 ,玻璃纤维是一种玻璃棉,其中的纤维截留了大量的气体,使其可用作绝缘体,尤其是在高温下。

生产过程玻璃纤维增​​强玻璃纤维光栅厂,集液槽盖,管盖,排水格栅,格栅检修孔,

所有成分均在电炉中在高达1370°C的高温下熔化以获得玻璃水。然后将纤维从挤出头中抽出并以高于挤出玻璃纤维的速度卷起。这相当于在纤维仍较弱的同时进行拉伸,从而在凝结之前形成较小的纤维。如果要制造短纤维,可以通过风切来完成。可以制成不同长度的纤维

在熔化过程中如果对要纯化的成分没有质量控制,则必须先将玻璃水加热并精炼成玻璃珠,以便将纯净的玻璃再次融化为玻璃水。但是如果成分的质量得到控制然后可以熨烫炉子中玻璃水中的纤维

“玻璃纤维”是增强材料的意思。

它可以通过两种方式生产:首先,将原型零件抛光到外部,并去除蜡。将玻璃纤维布放在原型件上。它涂有与增强剂混合至所需厚度的树脂。树脂硬化后,将玻璃纤维零件从原型中移除。进行抛光以完成外表面的抛光与第二种模制方法不同,用这种方法制造玻璃纤维部件缺乏细节和美观。此方法适用于大量零件。但是,比第一种方法要难得多。我们必须首先从原型零件制造模具。当模具然后用于创建所需的玻璃纤维零件所制作的作品在各个方面都与原型一样美丽。并且可以通过添加玻璃纤维厚度的几层强化所需的区域。

聚酯树脂

它是一种液态塑料。它看起来像机油一样浓。强烈的刺激性气味会随着高温而变硬。是一种易燃物质全套后的收缩率为2-8%。树脂可模制成多种应用。铸造通用工程,铸造僧侣,铸造纪念品的树脂铸造娃娃等玻璃纤维铸造用树脂以及科学框架涂料等涂料作业用树脂边铸边树脂释放出具有刺激性气味的化学气味。因此,工作场所应通风良好。不应在坚固的房间中工作。并且没有足够的空气流通或通风。

树脂根据其性能等级进行分类:

1.邻苯二甲酸类型是常用的

等级2.间苯二甲酸类型是耐酸碱性的类型

3.双酚类型是耐酸的类型-高碱

4.等级氯类型,高耐酸碱类型

5。乙烯基酯是一种对酸-碱具有极强抵抗力的类型,其性能仅次于环氧树脂

,该树脂根据质地分为两类:

1.不促进是未与催化剂混合的树脂树脂。树脂的性质将是像油一样的稠油。具有淡黄色透明色最重要的是3个月的保质期(对于潮湿的泰国,应在1个月内使用,因为进入第2个月和第3个月时树脂将开始具有较高的粘度),并且可以使用更多的配方。适合各种形式的工作2型非促进型聚酯树脂

促进剂是与催化剂混合的一种树脂,其性质是像机油一样的浆料。但紫红色粉红色,因为它是一种已与催化剂混合的树脂使用时,只需添加加速器。在彩色树脂方面,一些制造商可能会使用不同的促进剂,因此一些像草胶这样的含水树脂会具有较深的颜色。对于用于透明铸造的类型,树脂将具有颜色浅蓝色透明优点是易于使用且没有困难地流利,但是缺点是保质期短。实际使用中的保质期不超过2个月,应在1个月内使用

聚酯树脂的性能

树脂是具有物理,电气和化学铸造塑料

特性的。它具有坚硬,透明,发亮的特性,比热塑性塑料(白塑料)具有更好的耐高温性能,但比金属要差。用玻璃纤维加固时会获得更大的强度,重量轻,韧性强,不脆性,电性能树脂具有完整的电性能。可用作绝缘体(绝缘体)

聚酯树脂的使用特性。

树脂可用于许多应用中。但分为3个通常在我们家庭中常用的大组,包括:

1.铸造(铸造),例如铸造佛像,铸造礼品,铸造纽扣,人造玻璃铸造等

。2.涂层(层压板),科学框架

3.模制工作组,例如玻璃纤维制造或FRP(玻璃纤维增​​强塑料),玻璃纤维增​​强塑料。

树脂固化

聚酯树脂可以通过几种方式固化:

1.通过使用催化剂或硬化+加热

剂2.通过使用催化剂或硬化剂+催化剂。促进/促进在室温下

3.使用紫外线

4.使用电子

5.使用阳光

6.使用热量

通常,树脂的固化分为两个阶段:1.胶凝时间是指从添加催化剂到树脂凝结的时间; 2.固化时间是指树脂完全固化的时间,而固化时间是指树脂完全固化的时间。在反应过程中加热后,树脂冷却。

影响树脂硬化的要素

1.在高温下,树脂的固化速度比低温下的固化速度快的固化

2.促进剂的量大,而促进剂量比少量的量快

3.水分或水高湿度下,树脂的凝结变慢。工作表面是朦胧的。通常,树脂中的水含量不得超过0.05%.

4氧含量。氧气是一种树脂防冻剂。如果氧气含量高如长时间搅拌树脂,树脂的固化将减慢。氧气对于延长树脂的保质期非常有用。如果开始储存树脂的时间更长储罐中应产生氧气。或通过来回滚动桶进行窥视为了让内部的树脂移动会产生氧气并且会导致树脂的保质期略长

1.什么是塑料? (工厂制造商磨碎池塘盖,管盖,排水g子,磨碎人孔)

塑料是一种合成材料。具有非常广泛的意义(就像生活一词塑料是人类130多年以来已知的合成材料,被用作金属,木材或其他天然材料(如纺织品,船只和包装材料)的替代品。包括许多其他设备和电器塑料是合成天然来源的原材料(例如石油)的材料。分离成化合物多种纯服用每种化合物时反应类型将导致“塑料”,由不同化合物形成的塑料也将具有不同的特性。

塑料类型

1.热塑性(软塑料)软

加热时,塑料会软化,熔化。而且在冷却时,它变得僵硬可以将这种塑料重新熔合并再次使用。因此,由此类塑料制成的废料或用过的物品可以被压碎并重新使用,例如聚乙烯,聚丙烯,聚氯乙烯(聚氯乙烯)等

。2热固(硬)

.加热并塑料硬塑料而不软化。但是会焦灼的这种塑料制品。挤出或混合使用时,不能再次熔化。因此,请丢弃将制成这种塑料的废旧物品。因此不能被压碎并再次使用由于固化导致塑料发生化学变化这种塑料是由软塑料制成的。通过在软塑料中添加称为硬化剂的催化剂。会立即使肉变硬它具有相对较高的强度,例如三聚氰胺,甲醛(三聚氰胺甲醛),酚醛(酚醛),聚酯(Polyester),以玻璃纤维制品的形式广为人知。聚氨酯(Urethane)E-Fox(Epoxy)

2.什么是复合材料(Composite)?

复合材料是包含材料的产品的名称。两个或更多聚在一起或合作使用每种材料的显着特性复合材料的例子

轮胎很容易理解,它由两种主要材料制成:橡胶和钢丝。通过利用钢的强度和橡胶的弹性来获得柔软性不能以任何方式使用或者,但是不好,例如,如果仅使用铁,它将不会很柔软或仅使用橡胶,它将有很大的重量而且不强钢筋混凝土是其卓越性能的另一个例子。混凝土的抗压强度低,成本低,经久耐用,易于寻找,具有出色的抗压和抗拉强度的钢材,但价格高且由于容易生锈,因此非常易于维修

许多人都知道玻璃纤维。无论是复合材料还是增强塑料像纤维增强塑料(玻璃纤维增​​强塑料,FRP)或玻璃纤维增​​强塑料(玻璃纤维增​​强塑料,GRP),但实际上玻璃纤维是纺成细细线的玻璃纤维。在许多类型的聚合物中用作增强材料。包括可以模制成皮卡车车顶,浴缸,船,小型飞机零件等产品的塑料树脂。大水箱赛车零件等,因为玻璃纤维具有强度特性高拉伸强度,永不生锈和耐腐蚀。此外,玻璃纤维还具有良好的绝缘性能,也适用于炉子,冰箱或建筑材料

3.凯夫拉纤维“凯夫拉纤维”

是芳纶纤维,由杜邦公司Stephanie Kwolek发现。 1971年(1971年)合成基于对苯二甲酰氯(TPC)酰氯(TPC)和对苯二胺(PDA)的缩合作用,凯夫拉尔纤维经常用于工业应用。在长纤维的情况下,凯夫拉尔在工业上用于制造帆布,轮胎,管道和皮带。凯夫拉尔29也在长纤维的形式用于制造电缆,降落伞和凯夫拉尔增强带; LAR 49的形式长和短的床单。主要用于纤维增强塑料,航空航天,船体及相关建筑应用领域。它具有良好的耐高温性能。实力出众可以承受高达427摄氏度的热量,是钢的7倍,但不耐磨损而且不灵活脆弱的当强烈弯曲时

4.碳纤维

被归类为复合材料。并且性质根据生产性质而变化基本结构的特征是一根非常小的单纤维。纤维中的强度非常高。高于相同重量的金属当碳纤维排列在同一方向时。使用环氧树脂作为粘合剂它将获得一种看起来像木板的材料,我们可以在木锉中将其撕开。但不能打断网络为了使用碳纤维,有必要以使碳纤维像胶合板那样交叉或交叉的方式编织它们。这样就可以保持强力线因此,设计必须适合使用的性质,并且负载线很重要。用于采用碳纤维生产中必须考虑到它们的使用性质,这一点很重要。碳纤维材料(例如管和圆盘)的强度比金属强。因此,它可以做得更轻,同时仍比相同尺寸的金属更坚固。碳纤维的使用寿命非常耐用。碳纤维的强度或耐久性部分归因于环氧树脂,它是纤维之间和层之间的粘合剂

5.聚氨酯泡沫。 (聚氨酯泡沫)

是液体塑料热固性类型。 (热固性)常用于人造作品,例如人造木材的仿制。 (泡沫珠的尺寸很小)来制造汽车保险杠。内部组件,例如方向盘和控制台面板,假肢和模具加固(较大的泡沫珠)以及冷库绝缘子。有两种类型液体:

的类型1像聚酯树脂一样淡黄色,称为泡沫白或多元醇;

类型2几乎烧成褐色,称为泡沫黑或二碘。 (二异氰酸酯)

聚氨酯是一组聚合物。广泛使用是因为它是一种弹性材料柔软到坚固的材料轻质聚氨酯分为三类:

-挠性聚氨酯泡沫(挠性聚氨酯泡沫)

-聚氨酯硬质聚氨酯泡沫(硬聚氨酯泡沫)

-电子。弹性体(聚氨酯弹性体)

  1. ABS(丙烯腈-丁二烯-苯乙烯)

ABS是一种低易于加工和制造的低成本工程塑料。ABS是需要抗冲击性,强度和刚度的结构应用的理想材料,由于其具有出色的尺寸稳定性并且易于加工,因此被广泛用于机加工预生产的原型。油漆和胶水。天然(米色)ABS和黑色ABS均符合FDA的食品加工要求。以下物理性能信息基于基础丙烯腈-丁二烯-苯乙烯树脂的典型值
