Process Features: PC plastic materials greater absorption PC 3117 Bayer Thailand, must be preheated and dried before processing, drying of pure PC 120 ℃, modified PC for general use temperature 110 ℃ dried over four hours. Drying time can not exceed 10 hours. Generally available air extrusion determine whether sufficient drying. Use ratio up to 20% recycled material. In some cases, the use of 100% recycled materials, the actual amount depending on the product quality requirements. Recycled materials can not mix different masterbatch, otherwise it will seriously damage the properties of the finished product. Mold and gate design common mold temperature of 80-100 ℃ PC 3113 Bayer Thailand, plus glass of 100-130 ℃, small articles needle-shaped gate, gate depth should be 70% of the thickest part of the other gate annular and rectangular. Gate bigger the better, in order to reduce the plastic is caused by excessive shear defects. Vent depth should be less than 0.03-0.06mm, the flow path as short and round, stripping slope is generally about 30'-1. Melt temperature of the air injection can be used to determine the level of the processing temperature. General PC plastics processing temperature 270-320 ℃, some modified or low molecular weight PC plastic materials 230-270 ℃. Injection speed too fast injection speed is more common with molding, electrical switches such as playing pieces. Common to Slow - rapid prototyping. Back pressure of about 10bar back pressure in the absence of gas lines and mixing conditions can be appropriately reduced. The residence time in the long residence time at high temperature, the material will be degraded, put also CO2, turns yellow. Do not use LDPE, POM, ABS or PA cleaner cartridge. Application of PS cleanup. Three applications of engineering plastics PC application is glazing, automotive and electronics, electrical industry, followed by industrial machinery parts also, CDs, packaging, computers and other office equipment, medical and health care, film, recreation and protection equipment . PC can be used as window glass, PC laminates are widely used for protective windows in banks, embassies, detention centers and public places for aircraft canopy PC, lighting equipment, industrial safety bumpers and bulletproof glass. PC and PC alloys do computer racks, enclosures and auxiliary equipment, printer parts. Modified PC-resistant high-energy radiation sterilization, resistant to cooking and baking disinfection apparatus for blood samples, blood oxygenator, surgical instruments, kidney dialysis and other PC Thai Bayer 2865, PC do helmets and safety helmets, protective masks, sunglasses and sports goggles. PC films are widely used in printing the chart, medical packaging, film commutator [6]. Polycarbonate application development is the high complex, highly functional, specialized, serialization direction, has launched a CD-ROM, automobiles, office equipment, housing, packaging, pharmaceuticals, lighting, film and other products of the respective special grade grades.
