some modified pc plastic raw materials, because the number of recycling too much (molecular weight reduction)/a variety of ingrents mixed uneven, easy to produce dark brown liquid bubble. [1]

pc resin is a polar non crystalline polymer, density: 1.380 g/cm3, glass transition temperature: 87 degrees c, so the thermal stability is poor, not easy to process. can not be used directly, must be modified mixing, adding related additives&filler can be used. it is determined that the properties&requirements of the prepared pvc materials are different because of the different kinds&fractions of the additive&filler. we usually call it a pvc formula, which is strictly a pvc modified formula,&pvc is only modified to use. this class is often classified as polymer modified material. the modification of polymer materials mainly revolves around the high performance of general plastics, the conversion of single component materials to multi component materials&co-ites,&the functionalization&optimization of materials. in general, pvc should be modified to granulate first,&after the formation of particles by screw extruder, the plasticization is more sufficient&the processing is easier, espelly the process is the injection product. the screw extruder is one of the most important equipments in plastic molding. it is used for solid conveying, compaction, melting, shearing&mixing extrusion of plastics through external power transmission&heat transfer of external heating elements. screw extruders play an important role no matter as plasticizing&granulating machines/molding machines. strictly speaking, there are spel requirements for pvc products. pvc modified formula is made according to customer requirements. there are also copolymerization in the pvc production process, such as vinyl chloride copolymers, pvc blends,&chlorinated polyvinyl chloride (pvc) [3].
