What is pvc material

PVC is the abbreviation of Polyvinyl Chloride in English, and the Chinese scientific name is PVC. Using amorphous materials as raw materials, it has super high performance in oxidation resistance, strong acid resistance and reduction resistance. PVC also has high strength and excellent stability, and is not flammable, and can resist the corrosion caused by climate change. It is a very good material. Because of its high safety, it can be seen everywhere in life. At the same time, PVC, as a plastic product with huge global output, is divided into soft and hard PVC types, which provide different choices for different applications. Among them, soft PVC is usually used as the surface material of floor and ceiling, while hard PVC material is more used in corrugated board, door and window structure, and various chemical industry manufacturing. And PVC material is also changeable. By adding different additives, it can change the physical properties and mechanical properties of PVC, and can cope with different applications. For example, the soft and hard PVC mentioned above can even be made into transparent materials for special needs. Characteristics PVC material not only has many advantages, such as corrosion resistance, non-flammability, insulation, oxidation resistance, etc., but also has a high sales volume in the material market because of its reprocessing and low production cost. At the same time, it is also due to its wide range of uses and friendly prices. Multi-functions have not increased its value, but have been occupying a piece of the material market at a cheap price. At present, China's PVC material improvement and design technology have reached the international advanced level. From the previous need to import special PVC materials from abroad to now, we can replace imports with PVC independently developed and produced, and start to export products to foreign countries.

What material is pvc

What material is pvc What kind of material is pvc? We can often hear about it in our life. Many decoration materials are made of pvc, and they are widely used. Let's share what kind of material is pvc. Advantages and disadvantages of pvc: 1. Advantages of pvc: (1) PVC has the advantages of flame retardant (flame retardant value is above 40), high chemical resistance (resistance to concentrated hydrochloric acid, sulfuric acid with concentration of 90%, nitric acid with concentration of 60% and sodium hydroxide with concentration of 20%), good mechanical strength and electrical insulation. (2) Pvc has stable physical and chemical properties, insoluble in water, alcohol, gasoline, and low gas and water vapor leakage. (3) PVC is characterized by flame retardancy, so it is widely used in fire protection applications. However, PVC will release hydrogen chloride and other toxic gases, such as dioxin, during the combustion process.

PVC modification method

PVC resin is a polar non-crystalline polymer with density of 1.38 g/cm3 and glass transition temperature of 87 ℃. Therefore, it has poor thermal stability and is not easy to process. It cannot be used directly. It can only be used after modification and mixing, adding relevant additives and fillers. However, due to the different types and fractions of relevant additives and fillers added, the properties and requirements of PVC materials prepared are different. We usually call it PVC formula. Strictly speaking, it is PVC modified formula, and PVC can only be used after modification. This category is often classified as polymer modified materials. The modification of polymer materials mainly focuses on the research of the high-performance of general plastics, the transformation of single-component materials to multi-component materials and composites (alloy, blending, composite), the functionalization of materials, and the optimization of performance and price. The modification methods mainly include chemical modification, filling modification, reinforcement modification, blending modification and nano-composite modification. The basic principle of modification is to endow materials with functions or improve some properties through additives. Therefore, the level of PVC formula technology determines the level of technology and production capacity of a factory. PVC generally needs to be modified and granulated first. After the particles are prepared by screw extruder, the plasticization is more sufficient and the processing is easier, especially for injection molding products. Screw extruder is one of the main equipment for plastic molding and processing. It carries out solid conveying, compaction, melting, shearing, mixing and extrusion of plastic through external power transmission and heat transfer of external heating elements. Screw extruder plays an important role as both plasticizing and granulating machinery and molding and processing machinery. Strictly speaking, PVC products with special requirements and PVC modified formula are customized according to customer requirements. There is also copolymerization and derivation in the production process of PVC. Such modified varieties include vinyl chloride copolymer, PVC blend and chlorinated PVC, etc
