ไฟเบอร์กล๊าสคืออะไร | FibreGlass Definition

Fiberglass Products Fiberglass Reinforced Plastic or Glass Reinforced Composite or other plastic material for reinforcement. The material used to strengthen the plastic is “glass fiber”, which looks soft but sticky. High heat resistance Plastic parts used as meat. Must be very hard. If no reinforcement is fragile. So we chose plastic. Polyester Resin Vinyl ester resin And epoxy resin This plastic is a liquid plastic which after mixing with Catalysts or hardeners react chemically. The heat is above 100 ° C. It turns into a rigid plastic and will not return to a shape anymore, which is called a process. Thermosetting
Therefore, the creation of products by the way. It is called. Fiberglass reinforced plastic products or FRP, which we simply called fiberglass products or FRP products.
Fiberglass or fiberglass can be divided into two types according to the nature of the fiber. Continuous fibers are similar to yarns (Figure 1), which can be woven into a fiberglass fabric (Figure 2). The fabric is not absorbent, does not shrink, prevents heat. Most of them are used in the industry such as fire curtains. Another type of fiber is the short fiber. It is used for insulation and sound insulation, which is a thick sheet (see Figure 3).
The main ingredient used to make the fiber is silica sand. It is used to make soda ash and limestone. The two substances reduce the melting point. In addition to the three main ingredients, other ingredients may be used to improve the properties of the fiber, such as borax, feldspar, calcined alumina, magnesite, neffilene. Nepheline syenite and kaolin clay.

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)
ดังนั้นการสร้างผลิตภัณฑ์ขึ้นมาโดยวิธีการดังกล่าวแล้ว จึงเรียกได้ว่าเป็น ผลิตภัณฑ์พลาสติกเสริมแรง ด้วยใยแก้ว หรือ FRP ซึ่งเราเรียกง่ายๆ ว่า ผลิตภัณฑ์ไฟเบอร์กลาส หรือ ผลิตภัณฑ์เอฟอาร์พี
ไฟเบอร์กลาสหรือเส้นใยแก้วแบ่งได้เป็นสองประเภทตามลักษณะของเส้นใย คือเส้นใยต่อเนื่องคล้ายกับเส้นด้าย (ดังรูป 1) ที่สามารถนำมาถักทอให้เป็นผืนผ้า (fiberglass fabric) (ดังรูป 2) ผ้าที่ได้จะไม่ดูดซึมน้ำ ไม่หดตัว ป้องกันความร้อนได้ดี ส่วนมากจะนำไปใช้ในด้านอุตสาหกรรม เช่น ทำเป็นผ้าม่านกันสะเก็ดไฟ ส่วนเส้นใยแก้วอีกประเภทหนึ่งจะเป็นเส้นใยที่สั้นไม่ต่อเนื่อง มักนำมาใช้ทำเป็นฉนวนกันความร้อน และ ฉนวนกันเสียง ซึ่งมีลักษณะเป็นแผ่นหนานุ่ม (ดังรูป 3)
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.

Some people know that “fiberglass” is a composite material. Or plastic reinforcement Used as a canopy truck or bathtub. But really “Fiberglass” is a “fiberglass” means a direct translation of the fiber is used as a reinforcement material for resin plastics and molding products such as roof, pickup truck tub, small aircraft parts, water tank size. Big race car parts Glass Reinforced Concrete (GRC), etc., in addition to strength. Tensile strength is very high. Fiber is also the property. Heat insulation In addition, the fiber can be woven into a piece of cloth, and with the structure that makes it. Products are made of Fiber has a gap. The trapped material has the ability to prevent heat. Suitable to fabric underneath. Good insulation is the same as that used with refrigerators or coats. The fabric of the fiber does not absorb water. Use as a waterproof fabric. No shrinkage and no effect from water.
Fiber of various sizes and lengths. The fibers may be long like yarns. So long to very short fiber to see with the naked eye. Fiberglass made from sand, limestone, stone, tooth, boric acid and other additives. Melted inside At high temperatures up to 1370 degrees Celsius, if the quality control of the ingredients is very good. It is not necessary to make a crystal ball to select a good glass. After melting into glass water again, then into the process of rolling into long fibers. The fiber is pulled out of the rolling head. And is rolled at a speed higher than the speed of fiberglass. Extruded from the rolling head. This is equal to stretch while the fiber is weak. Fiber size Before the hardening. Long fibers are used to make curtains. To make a short fiber. It is cut to the wind to vary the length. Which is used to make tape or cloth. In industry To protect the sound Temperature and fire

Wax replica Place the fiberglass cloth on the master piece. Apply a hardened resin to the desired thickness when the resin solidifies and then remove the fiberglass pieces from the prototype. Fiberglass fabrication from this method is lacking in detail and beauty is different from the way the mold is used. This is ideal for many components, but it is a little more complicated than the first. We need to create a mold from the prototype. When the mold. The fiberglass components are required. The pieces are beautiful. Master It can be strengthened in the desired area by adding thickness. Of fiberglass multiple layers
Fiberglass is made from a variety of chemicals and materials. It is harmful to health, such as the eyes, skin, respiratory tract, so be careful and wear protective gear while making fiberglass pieces.
บางคนรู้จัก”ไฟเบอร์กลาส”ว่าเป็นวัสดุผสม หรือพลาสติกเสริมแรง ใช้ผลิตเป็นหลังคา รถกระบะ หรืออ่างอาบน้ำ แต่แท้จริงแล้ว “ไฟเบอร์กลาส” ก็คือ “เส้นใยแก้ว” มีความหมาย ที่แปลตรงตัว เส้นใยแก้วถูกนำไปใช้เป็นวัสดุช่วยเสริมแรงให้กับพลาสติกเรซิน และขึ้นรูป เป็นผลิตภัณฑ์ต่างๆ เช่น หลังคารถกระบะ อ่างอาบน้ำ เรือ ชิ้นส่วนเครื่องบินเล็ก ถังน้ำขนาด ใหญ่ ชิ้นส่วนรถแข่ง ผลิตภัณฑ์คอนกรีตเสริมใยแก้ว(Glass Reinforced Concrete, GRC) เป็นต้น นอกจากสมบัติความแข็งแรง ทนแรงดึงได้สูงมากแล้ว เส้นใยแก้วยังมีสมบัติด้าน การเป็นฉนวนความร้อน ถูกใช้เป็นฉนวนในเตา ตู้เย็น หรือวัสดุก่อสร้าง นอกจากนั้น เส้นใยแก้วสามารถทอเป็นผืนผ้า เย็บเป็นชิ้น และด้วยโครงสร้างที่ทำให้ ผลิตภัณฑ์ทำจาก เส้นใยแก้วมีช่องว่างภายใน ที่ถูกดักเก็บไว้ทำให้มีความสามารถในการป้องกันความร้อนได้ดี เหมาะที่จะทำผ้าหนุนด้านใน เพื่อเป็นฉนวนที่ดีเช่นเดียวกับที่ใช้กับตู้เย็นหรือเสื้อหนาว ผ้าจากเส้นใยแก้วไม่มีการดูดซึมน้ำ ใช้เป็นผ้ากันน้ำ ไม่เกิดการหดตัวและไม่เกิดผลเสีย จากน้ำ

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.

 

ขั้นตอนการผลิตไฟเบอร์กล๊าสเสริมแรง Fiber Glass

Bring all the ingredients in an electric oven at a high temperature of 1370 degrees Celsius to obtain a glass of water. The fibers are then removed from the rolling heads and rolled at a speed higher than the speed of the extruded fiberglass. This is equal to elongation while fiber is weak, resulting in smaller fibers before hardening. To make short fibers, it is done by cutting with wind. Can be made of different lengths of fiber.
However, in the melting process. If there is no quality control of the ingredients, then it is necessary to melt and make the glass as a glass ball to refine the pure glass to melt the glass again. If the quality of the ingredients. The fiber from the glass in the oven.
The “fiberglass” in the definition of reinforcement material. There are two ways to do this. Place the fiberglass cloth on the master piece. Apply the resin to harden to the desired thickness. When the resin solidifies, remove the fiberglass pieces from the prototype. Scrub the skin outside. Fiberglass fabrication in this way is lacking in detail and aesthetics differs from the second method using molds. This method is suitable for many parts. But there are more complicated steps than the first. We need to create a mold from the prototype. When the mold. The fiberglass components are required. The parts are beautifully built like all prototypes. It can be reinforced in many areas by adding several layers of fiberglass.

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.

Applications of Fibre Glass Grating ตะแกรงไฟเบอร์กล๊าส

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.

ใยแก้ว (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 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

พลาสติกคือวัสดุสังเคราะห์ชนิดหนึ่ง ซึ่งมีความหมายกว้างมาก (เหมือนกับคำว่าสิ่งมีชีวิต ซึ่งหลากหลายมาก) พลาสติกเป็นวัสดุสังเคราะห์ที่มนุษย์รู้จักมานานกว่า ๑๓๐ ปี และนำมาใช้ประโยชน์ แทนโลหะ ไม้ หรือวัสดุธรรมชาติอื่นๆ เช่น สิ่งทอ เรือและวัสดุ บรรจุภัณฑ์ต่างๆ รวมทั้งอุปกรณ์และเครื่องใช้อื่นๆอีกมาก พลาสติกเป็นวัสดุที่สังเคราะห์วัตถุดิบที่ได้จากธรรมชาติ เช่น น้ำมันปิโตรเลียม มาแยกเป็นสารประกอบ บริสุทธิ์หลายชนิด เมื่อนำเอาสารประกอบแต่ละ ชนิดมาทำปฏิกิริยาก็จะได้ “พลาสติก” พลาสติกที่เกิดจากสารประกอบที่ต่างกันจะมีสมบัติแตกต่างกันไปด้วย

ประเภทของพลาสติก

1. Thermoplastic (พลาสติกอ่อน)
พลาสติกอ่อนเมื่อถูกความร้อนแล้วจะอ่อนตัวหลอมละลาย และขณะเย็นตัวจะมีความแข็ง พลาสติกชนิดนี้สามารถนำไปหลอมละลายกลับไปใช้ใหม่อีกครั้งก็ได้ ดังนั้นเศษหรือของที่ใช้แล้วที่ทำจากพลาสติกชนิดนี้จึงสามารถนำไปบดแล้วหลอม ใช้ใหม่ได้ ได้แก่ โพลีเอทเทลีน(Polyethelene) โพลีโพรไพลีน( Polypropylene)โพลีไวนิลคลอไรด์(Polyvinyl Chloride) เป็นต้น
2. Thermoseting (พลาสติกแข็ง)
พลาสติกแข็งเมื่อถูกความร้อนแล้วไม่อ่อนตัว แต่จะไหม้เกรียมไป ผลิตภัณฑ์พลาสติกชนิดนี้ เมื่ออัดขึ้นรูปหรือผสมใช้งานแล้วจะนำมาหลอมใช้อีกไม่ได้ ดังนั้นเศษหรือของที่ใช้แล้วที่จะทำพลาสติกประเภทนี้ จึงไม่สามารถนำมาบดหลอมใช้อีกได้ เนื่องจากแข็งตัวทำให้เนื้อพลาสติกเกิดการเปลี่ยนแปลงทางเคมี พลาสติกชนิดนี้ทำมาจากพลาสติกอ่อน โดยการเติมตัวเร่งที่เรียก ว่า Hardener ลงไปในเนื้อพลาสติกอ่อน ก็จะทำให้เนื้อแข็งขึ้นทันที มีความแข็งแรงค่อนข้างสูง เช่น เมลามีนฟอร์มาเดลไฮด์ (Melamine Formaldehyde) ฟีโนลิค(Phenolic ),โพลีเยสเตอร์( Polyester )รู้จักโพลีเยสเตอร์ดีในรูปของผลิตภัณฑ์ไฟเบอร์กล๊าส ยูรีเทน(Urethane ) อีฟอกซี่ ( Epoxy )

2. คอมโพสิท(Composite)คืออะไร

Composite เป็นชื่อเรียกของผลิตภัณฑ์ที่ประกอบด้วยวัสดุ ตั้งแต่สองชนิดขึ้นไป มาประกอบหรือร่วมมือกัน เพื่อใช้คุณสมบัติเด่นของแต่ละวัสดุ ตัวอย่างของวัสดุคอมโพสิท ที่เข้าใจได้ชัด ได้แก่ ยางรถยนต์ ซึ่งประกอบมาจากวัสดุหลักสองชนิดคือยางและเส้นลวดเหล็ก โดยใช้คุณสมบัติความแข็งแรงของเหล็กและการยืดหยุ่นของยางเพื่อความนุ่มนวล โดยใช้อย่างไดอย่างหนึ่งไม่ได้ หรือได้แต่ไม่ดี เช่น ถ้าใช้เหล็กอย่างเดียวก็จะไม่นุ่มนวล หรือใช้ยางอย่างเดียวก็จะน้ำหนักเยอะ และไม่แข็งแรง คอนกรีตเสริมเหล็ก เป็นอีก ตัวอย่างที่ใช้คุณสมบัติเด่น คอนกรีตในด้านการรับแรงอัดและราคาที่ถูกทนทาน หาง่าย กับเหล็กที่เด่นทั้งการรับแรงอัดและแรงดึงแต่ราคาสูงและ การซ่อมบำรุงสูงเนื่องจากเป็นสนิมได้ง่าย
หลายคนรู้จักไฟเบอร์กลาส ว่าเป็นวัสดุคอมโพสิตหรือพลาสติกเสริมแรง อย่างพลาสติกเสริมแรงด้วยเส้นใย (fiber-reinforced plastic, FRP) หรือ พลาสติกเสริมแรงด้วยแก้ว (glass-reinforced plastic, GRP) แต่แท้จริงแล้วไฟเบอร์กลาส คือ เส้นใยของแก้วที่ปั่นให้เป็นเส้นละเอียดบางๆ เพื่อนำมาใช้เป็นวัสดุเสริมแรงในพอลิเมอร์หลายประเภท รวมทั้งพลาสติกเรซินที่สามารถนำมาขึ้นรูปเป็นผลิตภัณฑ์ต่างๆ เช่น หลังคารถกระบะ อ่างอาบน้ำ เรือ ชิ้นส่วนเครื่องบินเล็ก ถังน้ำขนาดใหญ่ ชิ้นส่วนรถแข่ง เป็นต้น เพราะเส้นใยแก้วมีสมบัติความแข็งแรง ทนแรงดึงได้สูง ไม่เป็นสนิม และทนต่อการกัดกร่อน นอกจากนี้เส้นใยแก้วยังมีสมบัติด้านการเป็นฉนวนความร้อนที่ดีเหมาะที่จะนำมาใช้เป็นฉนวนในเตา ตู้เย็น หรือวัสดุก่อสร้างอีกด้วย

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? 
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.

Polypropylene មានផ្ទៃរអិលដែលអាចជំនួសឱ្យសារធាតុប្លាស្ទិកដូចជា Acetal (POM) ក្នុងការប្រើប្រាស់កកិតទាបដូចជា Gear ឬសម្រាប់ជាចំណុចទាក់ទងសម្រាប់គ្រឿងសង្ហារឹម។ ប្រហែលជាទិដ្ឋភាពអវិជ្ជមាននៃគុណភាពនេះគឺថាវាអាចពិបាកក្នុងការភ្ជាប់ Polypropylene ទៅនឹងផ្ទៃផ្សេងទៀត (ឧទាហរណ៍វាមិនប្រកាន់ខ្ជាប់នូវកាវបិទជាក់លាក់ដែលធ្វើការល្អជាមួយបាស្ទិកផ្សេងទៀតហើយជួនកាលត្រូវបានផ្សារភ្ជាប់នៅក្នុងព្រឹត្តិការណ៍ដែលបង្កើតបានជាសន្លាក់។ ) ។ ទោះបីជាពពួក Polypropylene រអិលនៅកម្រិតម៉ូលេគុលក៏ដោយក៏វាមានមេគុណកកិតខ្ពស់ដែរដែលនេះជាមូលហេតុដែលប្រើអាអេតាឡា, នីឡុងឬ PTFE ។ Polypropylene ក៏មានដង់ស៊ីតេទាបទាក់ទងនឹងផ្លាស្ទិចទូទៅផ្សេងទៀតដែលមានន័យថាការសន្សំសំចៃទម្ងន់សម្រាប់ក្រុមហ៊ុនផលិតនិងអ្នកចែកចាយនៃផ្នែក Polypropylene ដែលបានចាក់ដោយចាក់។ វាមានភាពធន់ទ្រាំពិសេសនៅសីតុណ្ហភាពក្នុងបន្ទប់រំលាយសារធាតុសរីរាង្គដូចជាខ្លាញ់ប៉ុន្តែត្រូវបានកត់ទុកនៅក្នុងសីតុណ្ហភាពខ្ពស់ជាងមុន (បញ្ហាដែលអាចកើតមានក្នុងកំឡុងពេលផ្សាំ) ។
អត្ថប្រយោជន៍ដ៏សំខាន់មួយរបស់ Polypropylene គឺថាវាអាចផលិតបាន (តាមរយៈម៉ាស៊ីនភ្លើងស៊ីអេសអិលឬផ្សិតចាក់កំដៅឬកាត់) ចូលទៅក្នុងចង្កេះដែលកំពុងរស់នៅ។ ចន្ទីរស់នៅគឺជាបំណែកនៃប្លាស្ទិចស្តើងបំផុតដែលពត់ដោយគ្មានការបំបែក (សូម្បីតែលើជួរខ្លាំងនៃចលនាជិត 360 ដឺក្រេ) ។ ពួកវាមិនមានអត្ថប្រយោជន៍ពិសេសសម្រាប់កម្មវិធីរចនាសម្ព័ន្ធដូចជាការកាន់ទ្វារធ្ងន់ប៉ុន្តែវាមានអត្ថប្រយោជន៍ពិសេសសម្រាប់កម្មវិធីដែលមិនផ្ទុកដូចជាគំរបនៅលើដបទឹកប៉េងប៉ោះឬសាប៊ូកក់។ Polypropylene គឺមានភាពឆ្លាតវៃសម្រាប់ការរស់រានមានជីវិតដោយសារតែវាមិនខូចនៅពេលដែលកោងម្តងហើយម្តងទៀត។ គុណសម្បត្តិផ្សេងទៀតគឺថា polypropylene អាចត្រូវបានម៉ាស៊ីន CNC ដើម្បីរួមបញ្ចូលចង្កាការរស់នៅដែលអនុញ្ញាតឱ្យមានការអភិវឌ្ឍគំរូដើមលឿននិងមានតម្លៃថ្លៃជាងវិធីសាស្រ្តគំរូផ្សេងទៀត។ យន្តការច្នៃប្រឌិតគឺមានតែមួយគត់នៅក្នុងសមត្ថភាពរបស់យើងក្នុងការបង្កើតម៉ាស៊ីនត្រចៀកដែលរស់នៅពីផ្នែកមួយនៃ polypropylene ។
អត្ថប្រយោជន៍មួយទៀតនៃ Polypropylene គឺថាវាអាចត្រូវបានគេធ្វើជាកូប៉ូលីលីតបានយ៉ាងងាយស្រួល (រួមបញ្ចូលគ្នាជាសារធាតុប្លាស្ទិចសមាសធាតុ) ជាមួយនឹងប៉ូលីមែរជាច្រើនដូចជាជ័រ។ copolymerization ផ្លាស់ប្តូរលក្ខណៈសម្បត្តិសម្ភារៈយ៉ាងខ្លាំង, អនុញ្ញាតឱ្យសម្រាប់កម្មវិធីវិស្វកម្មដ៏រឹងមាំជាងគឺអាចធ្វើទៅបានជាមួយ polypropylene សុទ្ធ (ច្រើននៃផលិតផលប្លាស្ទិចនៅលើខ្លួនវាផ្ទាល់) ។
លក្ខណៈដែលបានរៀបរាប់ខាងលើនិងខាងក្រោមមានន័យថា polypropylene ត្រូវបានគេប្រើនៅក្នុងប្រភេទផ្សេងៗនៃកម្មវិធីដូចជាចានដាក់ម្ហូបលាងចានចានកំប៉ុងកុងតាក់ដាក់ធុងនិងប្រដាប់ប្រដាក្មេងលេងជាច្រើន។

តើអ្វីខ្លះជាលក្ខណៈរបស់ Polypropylene?
លក្ខណៈសម្បត្តិសំខាន់ៗមួយចំនួននៃសារធាតុ polypropylene គឺ:
ភាពធន់ទ្រាំគីមី: មូលដ្ឋានរលាយនិងអាស៊ីតមិនមានប្រតិកម្មជាមួយនឹងប៉ូលីត្រូលីនដែលធ្វើឱ្យវាក្លាយជាជម្រើសដ៏ល្អសម្រាប់ធុងវត្ថុធាតុដូចជាវត្ថុសំអាតផលិតផលជំនួយដំបូងនិងអ្វីៗជាច្រើនទៀត។
ភាពបត់បែននិងភាពរឹងមាំ: Polypropylene នឹងធ្វើសកម្មភាពជាមួយនឹងភាពបត់បែនលើជួរជាក់លាក់នៃការបត់បែន (ដូចជាវត្ថុធាតុទាំងអស់) ប៉ុន្តែវាក៏នឹងមានការប្រែប្រួលប្លាស្ទិចឆាប់រហ័សក្នុងដំណើរការខុសគ្នាដូច្នេះវាត្រូវបានគេចាត់ទុកថាជាវត្ថុធាតុ “រឹងមាំ” ។ ភាពរឹងមាំគឺជាពាក្យវិស្វកម្មមួយដែលត្រូវបានគេកំណត់ថាជាសមត្ថភាពរបស់សម្ភារៈមួយដើម្បីបែកខ្ចាត់ខ្ចាយ (មិនត្រឹមតែមិនរលោងទេ) ដោយមិនខូច ..
ភាពធន់ទ្រាំមិនអស់កំលាំង: Polypropylene រក្សារូបរាងរបស់វាក្រោយពីមានការរមួលក្រពើជាច្រើនពត់កោងនិង / ឬបត់បែន។ ទ្រព្យសម្បត្តិនេះមានតម្លៃណាស់សម្រាប់ការធ្វើឱ្យចង្ការស់នៅ។
អ៊ីសូឡង់: អេប៉ីប៉ូត្រូលីនមានភាពធន់ទ្រាំខ្លាំងចំពោះចរន្តអគ្គីសនីហើយវាមានប្រយោជន៍សម្រាប់គ្រឿងអេឡិចត្រូនិក។
ការបោសសំអាត: ទោះបីជាថ្នាំ Polypropylene អាចត្រូវបានធ្វើឱ្យមានតម្លាភាពក៏ដោយវាជាធម្មតាត្រូវបានផលិតដើម្បីឱ្យមានពណ៌ស្រអាប់ពីធម្មជាតិ។ Polypropylene អាចត្រូវបានប្រើសម្រាប់កម្មវិធីដែលការផ្លាស់ប្តូរពន្លឺមួយចំនួនមានសារៈសំខាន់ឬជាកន្លែងដែលវាមានតម្លៃនៃសាភ័ណភ្ព។ ប្រសិនបើការចម្លងខ្ពស់ត្រូវបានគេចង់បានបែើបែស់បែើបែស់ផ្លាស្ទិចដូចជាអាសុីគ្លីកឬពែយាខាញូណាតគឺជាជម្រើសល្អជាង។
Polypropylene ត្រូវបានគេចាត់ទុកថាជា “thermoplastic” (ផ្ទុយទៅ “សម្ភារៈ thermoset”) ដែលទាក់ទងទៅនឹងវិធីដែលប្លាស្ទិកឆ្លើយតបទៅនឹងកំដៅ។ សម្ភារៈ Thermoplastic ក្លាយទៅជារាវនៅចំណុចរលាយរបស់វា (ប្រហែល 130 អង្សាសេក្នុងករណី polypropylene) ។ គុណសម្បត្តិដ៏សំខាន់មួយដែលទាក់ទងនឹង thermoplastics គឺថាវាអាចត្រូវបានកំដៅទៅចំណុចរលាយរបស់ពួកគេត្រជាក់និងឡើងវិញម្តងទៀតដោយគ្មានការរិចរិលយ៉ាងសំខាន់។ ជំនួសឱ្យការដុតកម្ដៅសម្ភារៈដូចជាពុលផាប់ផេលីនលីកហ្វូដែលអនុញ្ញាតឱ្យពួកគេងាយនឹងចាក់បញ្ចូលហើយត្រូវកែច្នៃជាបន្តបន្ទាប់។ ផ្ទុយទៅវិញប្លាស្ទិកកម្ដៅអាចត្រូវបានកំដៅតែម្តងប៉ុណ្ណោះ (ជាធម្មតាក្នុងកំឡុងពេលដំណើរការផ្សាំ) ។ កំដៅដំបូងបណ្តាលឱ្យសម្ភារៈ thermoset ត្រូវបានកំណត់ (ស្រដៀងទៅនឹង epoxy 2 ផ្នែក) ដែលជាលទ្ធផលនៃការផ្លាស់ប្តូរគីមីដែលមិនអាចផ្លាស់ប្តូរបានទេ។ ប្រសិនបើអ្នកព្យាយាមកម្តៅប្លាស្ទិកកំដៅខ្ពស់ជាលើកទីពីរវានឹងរលត់។ ចរិតលក្ខណៈនេះធ្វើឱ្យសម្ភារៈកម្ដៅសម្ភារក្រីក្រសម្រាប់ការកែច្នៃ។
