PC is the abbreviation of polycarbonate, polycarbonate in English is Polycarbonate, referred to as PC engineering plastics, PC material is actually what we call one of the engineering plastics, as a material widely used around the world, PC has its own characteristics and advantages and disadvantages, PC is an amorphous thermoplastic resin with excellent overall performance, has an excellent electrical insulation, extensibility, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance; also has a self-extinguishing, flame retardant, toxic, and can be used as a mobile phone case material. Excellent electrical insulation, extensibility, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable, etc., in all corners of your life can see the shadow of the PC plastic, large-scale industrial production and easy to process the characteristics of the price is extremely low. Its strength can meet a variety of needs from cell phones to bulletproof glass, the disadvantage is that compared with the metal hardness is not enough, which leads to the appearance of its easier to scratch, but its strength and toughness is very good, whether it is heavy pressure or general drop, as long as you are not trying to use a stone stone it, it will be long enough.
PC material-application areas
Wide-wave transmissive optical instruments, as a good transparent performance of engineering plastics, PC as a substrate for optical discs in the world a large number of uses, not only the preparation of CD, VCD, DVD discs, but also can be applied to the substrate for high-density recording of optical discs, in particular PC and styrene grafted to generate the **** polymer has an excellent application effect. PC sheet is particularly suitable for the production of eyeglass lenses, the introduction of silicone oxygen groups in the PC molecular chain, can improve its hardness and scratch resistance. PC as a high refractive index plastics for the production of high-temperature-resistant optical fiber core material, if the PC molecular chain in the C-H chain for the replacement of the C-F chain, it can be a reduction in the absorption of visible light, and can If the C-H chain is replaced by C-F chain in the PC molecular chain, the absorption of visible light can be reduced, which can effectively reduce the loss of signal on the way. In addition, PC good light transmission, in the transparent window material high-rise building curtain walls, airports and stadiums transparent building materials such as applications are very common and has the potential to focus on improving the surface hardness and antistatic properties in the future.
Flame-retardant environmentally friendly communication appliances, due to the good electrical insulation properties of PC, widely used in the field of communication and telecommunications equipment, PC has been a large number of replacements for the original phenolic plastics, the future focus on the development of flame-retardant PC used in the field of communication appliances, and therefore non-polluting flame-retardant PC materials have become the focus of development, bromine flame retardant due to the toxicity of the use of the reduction in the use of halogen-free environmentally friendly phosphorus flame retardant will significantly lower the heat distortion temperature and impact strength of PC. PC's heat distortion temperature and impact strength, so it is more suitable for silicone-based flame retardants. In addition, with the lightweight miniaturization of communication appliances on the PC material to put forward higher requirements, the current PC / ABS alloys are particularly suitable for use in communication appliances and aerospace industry.
Surface metallization of automotive parts, PC surface metallization has a good metallic luster and high strength, widely used in a variety of automotive parts, but the plating process will reduce its impact toughness, so the use of elastomers and PC **** mixing modification, the combined elastomers dispersed to cracking stress, although plating also does not reduce the toughness of its impact, so plating-level PC resin is very Therefore, plating grade PC resin is very promising. In addition, the surface metallization of PC can also be used as electromagnetic wave shielding materials, used in computers.
Low residual harmful food containers, industrial synthetic PC is a bisphenol type, due to the synthesis of trace unreacted monomer bisphenol A residue in the resin, as a drinking water barrels and food containers, easy to be dissolved and affect the health of the people, so the development of sanitary PC resin, used as a drinking water barrels and other food containers and the use of production, the prospects for domestic applications is very promising.
Anti-cracking and embrittlement of medical devices, PC has many excellent properties, has been applied to medical equipment, due to its poor chemical resistance, in the presence of chemicals can easily cause internal stress cracking, such as PC in artificial dialysis,
artificial lungs and other medical equipment to solve the problem of high-temperature disinfection leads to cracks in the aging phenomenon, if we overcome these shortcomings, PC in the medical devices. If these shortcomings are overcome, the application of PC in medical devices can be rapidly expanded.
Polycarbonate film and sheet PC FILM & SHEET main ingredient for the imported polycarbonate (PC) resin can be used in optics, control panels, remote panels, LCD windows, labels, chrome plates, automotive instrument panels, membrane switches, capacitors, capacitor dielectrics, audiotape, color video tape, and so on.
ABS is the abbreviation of Anti-lockBrakingSystem. The world's earliest ABS system was first applied in the aircraft
, and later became the standard equipment for premium cars, and now most of the cars are equipped with ABS.
It is well known that the brakes can not be a foot on the dead, but should be step by step braking, a step on the pine, until the car stops, but when it comes to the emergency braking, often need to stop the car emergency stops, and would like to a foot in the end of the car stops, and this time, due to the wheels are prone to clasp the wheel. However, in case of emergency braking, it is often necessary to stop the car urgently, and it is very tempting to stop the car with one foot in the end. At this time, because the wheels are prone to hold on and not rotate, which will make the car dangerous conditions, such as the front wheels hold on and cause the car to lose the ability to turn, and the rear wheels hold on and make it prone to rear end accidents. The ABS is installed to solve the problem of wheel locking when braking
Satisfied with the adoption of
