In theprocessing of thin-walled parts, only a few seconds, for largeparts only 40-60s can be. PCplastic raw materials market applications: 1. Optical lighting:Used for manufacturing large lampshade, protective glass, left andright eyepieces of optical instruments, etc. . It can also bewidely used in transparent materials on aircraft. 2. Electrical andelectronic equipment: polycarbonate is an excellent E (120 ° C)class insulating material, used for manufacturing insulatingconnectors, coil frame, pipe pedestal, insulating sleeve, telephonecase and parts, Miner's lamp battery case, etc. . It can also beused to make parts with high dimensional accuracy, such as compactdiscs, telephones, computer, video recorders, telephone switches,signal relays and other communication equipment. Polycarbonate thinfilm is also widely used as capacitors, insulating bags, audiotapes, color video tape, etc. . 3. Mechanical Equipment: Used formanufacturing various gears, rack, worm, worm, bearing, Cam, bolt,lever, crankshaft, Ratchet, it can also be used as housing, coverand frame of some mechanical equipment. Four. Medical Equipment:can be used as medical cups, barrels, bottles and dental equipment,drug containers and surgical instruments, and even can be used asartificial kidney, artificial lung and other artificial organs. 5.Other uses: In architecture, it is used as hollow rib double wallpanel, greenhouse glass, etc. . In textile industry, it is used astextile yarn tube, textile machine bearing, etc. . PCprocess features: 1. The aggregation is an amorphous plastic withno apparent melting point and high melt viscosity. Glasstemperature 140-150 degrees, melting temperature 215-225 degrees,molding temperature 250-320 degrees. 2. In the normal processingtemperature range, the thermal stability is good, 300 degreeslong-stay basically do not decompose, more than 340 degrees beganto decompose, viscosity is less affected by the shear rate. 3. Therheological properties are similar to those of Newton fluids. Theapparent viscosity is more affected by temperature than by shearrate, and increases with the increase of relative molecular weight.There is benzene ring in PC molecular chain, so the Chilton chainis rigid. Four. PC has good creep resistance and dimensionalstability, but internal stress is not easy to eliminate. 5. PC iseasy to be degr
