□PPS CZL-4033⌒Long term supply PPO coating and electrical performance, used in automobile dashboard, radiator grille, speaker grille, console, fuse box, relay box, connector, wheel housing. 7, electronic and electrical appliances industry is widely used in the manufacture of connectors, coil bobbins, mechanical parts, shield switch relay, tuning equipment, large electronic display, variable capacitors, batteries accessories, microphone and other components. 8, household appliances used in television sets, cameras, video tape, tape recorders, air conditioners, heaters, rice cookers and other parts. Can be used as copiers, computer systems, printers, fax machines and other components and components. 9, in addition to cameras, timers, pumps, blowers shell and parts, silent gears, pipes, valves, surgical instruments, sterilizers and other medical equipment parts. PPE molding process characteristics PPE is a comprehensive performance of thermoplastic engineering plastics, outstanding electrical insulation and water resistance, good dimensional stability. 1. dielectric properties in the first batch of Engineering Plastics: PPE resin molecular structure of no strong polarity group, stable electrical performance, can be in a wide range of temperature and frequency to maintain good electrical performance. PMMA organic glass: impact resistance is 200 times that of ordinary glass products above, almost no fracture risk; durability five, organic glass: product protection good of the built-in light source, prolong the using life of light source products; weather resistant six, organic glass: insurable long do not fade, the quality of sheet metal good service life for 6-13 years; flame resistance seven, organic glass: there will be no spontaneous combustion and self extinguishing; energy saving eight, organic glass: transparency is very good, relatively less light, energy saving, reducing the use cost; the rationality of nine, organic glass: the rationality of the design and the rain moistureproof, open structure, easy to clean and repair etc.. When the copolymer with 15 PA11 to 100 ratio of PA11 and PA6 has 5% copolymer, the impact strength and low temperature impact strength of blends are obviously improved. With the modified PE blend PE was blended with PA11, not only can reduce the water absorption rate of PA11, but also can improve the impact strength of PA11. The mechanical properties of PA11/PE blends were studied by graft polymerization of maleic anhydride (MA), PE (MA) and EPDM (ethylene / propylene / diene) copolymer as compatibilizer. The results show that the PE-g-MA and EPDM-g-MA of two kinds of compatibilizer can improve the impact toughness of PA11/PE blends obviously, and the tensile strength also has a certain contribution, when PA11: PE: PE-g-MA mass ratio of 75: 15: 10, PA11: PE: PE-g-MA: EPDM-g-MA. PPS used in plasticized PPS must be modified by cross linking to increase the viscosity of the melt. Generally, the melt index after crosslinking should be 10~20. The glass fiber reinforced PPS has a larger melting index, but not more than 200. The crosslinking methods of PPS include two kinds of thermal crosslinking and chemical cross-linking. The crosslinking temperature of the thermal crosslinking is 150~350 DEG C, lower than 150 DEG C, no cross linking occurs, higher crosslinking is higher than 350 DEG C, but the processing is difficult. Need to add chemical crosslinking crosslinking agent, specific varieties of Zinc Oxide, Magnesium Oxide, lead oxide, cobalt oxide and phenolic compounds, Hexamethoxymethyl melamine, hydrogen peroxide and alkali metal or alkaline earth metal hypochlorite. Although PPS is crosslinked, the fluidity is not greatly decreased; therefore, waste materials can be reused three times
