A wide range of household appliances, their use can be divided into: kitchen appliances, home appliances, audio-visual appliances, air conditioning class appliances, medical fitness and appliances, and other household appliances. In the home appliance plastic material, approximately 90% of thermoplastics, thermosetting plastics rest; thermoplastics, most common plastics, such as: PP, PS, PVC, PE and the like; engineering plastics are used mainly ABS, AS, PA, PC, POM, PPO, PPS, PET, PBT, PMMA, LCP, PEEK, PSF, PUR and the like. Thermosetting plastics typically include phenolics, aminoplasts, and epoxy resins.
In recent years, PP has excellent overall performance due to the characteristics of low price, low density and other aspects of home appliances become the largest and fastest-growing amount of plastic varieties. Especially in recent years the development of high gloss ABS PP in terms of alternatives to get a lot of applications. Inside and outside the tube PP is mainly used in the production of household appliances in the washing machine, base, dehydration barrel, cover, television shell, cover, fans of the housing member, gall refrigerator door, transparent drawers and microwaves and other small appliances shell pieces. Currently, the amount of household appliances account for about 30%.
PS is mainly used for the production of household appliances in the past transparent parts, now were more used as foam packaging materials; HIPS is often used to make the refrigerator door gall bladder, boxes of vegetables, meat dish, ice box, TV, computers, tape recorders, air conditioners, vacuum cleaners, telephones, keyboards, and other household appliances, housing, audio video cassettes, keyboard, and so on. In HIPS, and has a high gloss, high flow, resistance to environmental stress cracking of the fastest-growing varieties.
PVC application in small appliances, refrigerators typically are used as seals and some small injection molded parts, but the PVC / ABS, PVC / PS alloy due to low cost, can be substitute for ABS and HIPS TV cabinet, electrical fan, hair dryer, washing machine drum, vacuum cleaners and other requirements for the production of flame-retardant components.
PE is mainly used in the production of household appliances in the less demanding non-mechanical parts such as washing machines and vacuum cleaners ,, bellows.
Engineering plastics used in home appliances, ABS amount in the first place, is mainly used for the production of refrigerators lining, televisions, computers, audio recorders, air conditioners, vacuum cleaners, telephones, keyboards, and other small appliances and housing its internal structure. Among them, the inside of the transparent parts of the transparent outer member appliances and refrigerators are made transparent ABS.
AS can be used to make refrigerator vegetable dish, electrical switches, small appliances and transparent parts.
Because PC has good toughness, transparency, good high temperature performance, with self-extinguishing characteristics, is used extensively for hair dryer, electric heaters in the heat and flame of a transparent cover higher production. In addition, PC can be used for the production of high performance requirements of optical discs, PC / ABS alloy shell were used in the production of mobile phones.
PA series is commonly used appliances in gears, bearings and sliding parts production.
POM has good overall performance, in the past mainly for the production of household appliances gears, bushings and sliding parts. In recent years, POM alloy has been widely used in precision structural parts.
Heat-resistant plastic case of modified PPO, good overall performance, there are self-extinguishing, therefore, is commonly used in the production of television and radio components, sockets, insulation support, coil and so on.
By fiber reinforced PBT can be made after the coil, transformer shell; PET is mainly used as the base material of the tapes. In recent years, due to the relatively low price of PET, making all kinds of PET plastic blends and alloys generic alternative to other engineering plastics and has been widely used in small appliances.
PPS, LCP, PEEK, etc. are generally used to produce high heat precision structures, such as the connectors of the computer and the like.
PUR in the appliance can be used to make elastic components, such as rice cooker seals. More PUR rigid foam is used, heat insulation in the refrigerator, play a role in holding the rice cooker.
Thermosetting plastic, Bakelite is mainly used for the production of electric appliances floor type, switches, patch panels, fiber-reinforced parts, etc; mainly used for the production of amino plastic knobs, heat casing, decorative veneer; epoxy resin Mainly used for printed circuit boards and packaging material production.
The rapid development of home appliance industry and the high demand for plastics, and promote the development of the plastics industry, a number of synthetic resins dedicated appliances, such as polypropylene EPS30R, transparent ABS, transparent PA, high molecular weight PS, high gloss PS, high PC melt strength and so on. In addition, plastic modification technology has been further refined and improved, for example, maleic anhydride grafted polymer technology, high flow and high gloss PP PP preparation technology and PC / ABS alloy, PVC / ABS alloy, transparent PP, flame retardant ABS and other preparation techniques. The large demand for plastic alloy compatibility agent to promote the development of the preparation of the compatibility agent technology. Wherein the polymer preparation techniques of various MAH, MS resin, SEBS, SEDS, EAA, 4IP, IO, SPS, EVOH and a number used as a compatibilizer has matured, its synthetic products have been widely applications. Toughened plastics demand is to promote the rapid development of a thermoplastic elastomer, at present, the thermoplastic toughening POE, EPDM, SIS, TPU, SEBS, polyester elastomers, etc., have been widely used in plastics. While many powdered rubber used in plastics is growing rapidly.
Demand for the development and modification of home appliances also contributed to a number of development aid and its application technology. For example, the demand for halogen-free phosphorus-based flame retardant such that, nitrogen-based, silicon-based, boron-based flame retardant applications, and aluminum hydroxide, magnesium hydroxide and other inorganic flame retardant is broadened; nucleating agent in the PP, PET application effectively improve the performance of plastics; in thin-walled products and high-gloss materials are widely used in the flow modifier and brightener; due to the widespread use of glass fiber reinforced plastic, making the new aid - Fiberglass Exposed preventing agent emerged; antibacterial demand refrigerators, washing machines, telephone promoted the application of nano-antibacterial agent.
