The raw material of PVC produced by ethylene method is petroleum. Petroleum is cracked to produce ethylene, ethylene is chlorinated or ethylene oxychlorinated to synthesize dichloroethane, and then cracked to produce vinyl chloride, which is polymerized to form polyvinyl chloride.
The raw material of PVC produced by calcium carbide is coal. Coal and limestone at high temperatures to produce calcium carbide, calcium carbide meets water to produce acetylene, under the action of mercury chloride catalyst, acetylene and hydrogen chloride to synthesize vinyl chloride, and then by polymerization to make PVC.
Calcium carbide PVC resin application field
1) PVC building materials
The construction industry is one of the important areas of PVC application. PVC for building materials accounts for 65% of the total consumption of PVC, and the penetration rate of PVC indoor drainage pipes is more than 90%. PVC doors and Windows, PVC construction pipes, PVC waterproof materials are widely used
2.Industrial PVC plastic products
PVC pipe has excellent properties of acid resistance, alkali resistance and organic solvent resistance, so it is more suitable for conveying chemical media than other materials. At present, PVC pipe is mainly used for medium transportation in chemical, mining, petroleum and other industries. In addition, PVC pipe can also be used for slurry transportation in coal mining, mining, and underground transportation in oil fields, and can also be used for sewage pipes, ventilation pipes, wire cable pipes, etc.
3.Packaging materials and other PVC films
Economic development will drive the rapid development of industrial products, chemical products, mechanical and electrical products, washing supplies, cosmetics, beverages, packaging and transportation materials, clothing and other industries, which will produce a great demand for composite film, packaging film, containers, turnover boxes and other packaging products.
Vinyl PVC resin application field
Vinyl PVC is mainly used in high-grade profiles, transparent sheets, films and interior products of the automotive industry (such as roof lining, carpet, interior skin, insulating pipes, refueling funnel, door trim, bellows, seals, seats, instrument panel skin and other products).
The production of PVC in the international market is mainly based on ethylene method, while in China, due to resource constraints (rich coal, poor oil, less gas), it is mainly based on calcium carbide method. These two methods differ greatly in cost in different economic development cycles and regions. Therefore, the source of PVC can be traced back to both the petrochemical industry and the coal chemical industry, depending on the place of production and the process method used.
