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 and filler can be used. It is determined that the properties and requirements of the prepared PVC materials are different because of the different kinds and frbbbbbbs of the additive and filler. We usually call it a PVC bbbbula, which is strictly a PVC modified bbbbula, and 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 perbbbbance of general plastics, the conversion of single component materials to multi component materials and composites, and the functionalization and optimization of materials. In general, PVC should be modified to granulate first, and after the bbbbation of particles by screw extruder, the plasticization is more sufficient and the processing is easier, especially 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, compbbbbbb, melting, shearing and mixing extrusion of plastics through external power transmission and heat transfer of external heating elements. Screw extruders play an important role no matter as plasticizing and granulating machines or molding machines. Strictly speaking, there are special requirements for PVC products. PVC modified bbbbula is made according to customer requirements. There are also copolymerization in the PVC production process, such as vinyl chloride copolymers, PVC blends, and chlorinated polyvinyl chloride (PVC) [3].

Perbbbbance indicators of PVC modification

Colourability

The thermal stability and light resistance of PVC are poor. Hydrogen chloride was decomposed at 150 C, with the adverse rebbbbbb of the plasticizer content. In addition, the influence of pigment on PVC is reflected in whether pigment is reacted with PVC and other components of PVC products, and pigment itself is resistant to migration and heat resistance. Some of the ingrents in the coloring agent may cause the degradation of the resin. For example, iron ions and zinc ions are the catalysts for the degradation of PVC resin. Therefore, the use of iron oxide (red, yellow, brown and black) pigment or Zinc Oxide, zinc sulfide and white pigment lithopone will reduce the thermal stability of PVC resin. Some of the coloring agents may be associated with the degradation products of PVC resin. Such as ultramarine pigment acid resistance is poor, so in the PVC coloring process, with the PVC decombbbbbbbb of hydrogen chloride produced by the interbbbbbb of losing their color. Therefore, as far as PVC coloring is concerned, the characteristics of the resin and related auxiliaries are considered, and the characteristics of the pigments are combined. The following problems should be paid attention to when choosing a colorant.

EPS(1) cost barrier

PVC is a basic chemical raw material, and its product diversity is relatively small. Under the complebbby competitive market structure in China, the cost is the most important factor that affects the competitiveness of enterprises. As a result of industry characteristics, raw materials and energy occupy a high proportion in product cost. The cost of oil ethylene is mainly affected by the impact of the price of petroleum; calcium carbide production cost is mainly affected by the cost effect in general, calcium carbide, calcium carbide cost accounted for about PVC 70% of the cost, and the cost of electricity has accounted for about 60% of the cost of calcium carbide, because China is rich in power resources in the west, the electricity price is relatively low, compared with the production Eastern Enterprises calcium carbide production enterprises, the calcium carbide bbbbbb has certain advantages in terms of cost. With resource endowments, supporting the production of calcium carbide enterprises, will build more solid cost barriers.
