Bulk method polyvinyl chloride [r(br)] has been produced in China, at two companies in Yibin, Sichuan, Tianyuan, Inner Mongolia and Haiji. The transparency and insulation of this method's products are higher than those of other methods. Solution polymerized polyvinyl chloride resin is mostly used in surface coatings. Suspension emulsion or bulk polymerization at a low temperature of ~℃ or below is called low-temperature polymerization. Low-temperature polymerized polyvinyl chloride has high molecular weight, high crystallinity, good structural regularity, high glass transition temperature, and good heat resistance and solvent resistance. However, it is more difficult to process than ordinary polyvinyl chloride and has slightly lower impact strength. It is used as fiber and special plastic products. The polyvinyl chloride produced by emulsion polymerization is called emulsion polyvinyl chloride (r). It is a paste resin with a higher molecular weight and finer particles. The model of emulsion method polyvinyl chloride is R, where R is the absolute viscosity of emulsion method paste resin resin solution. By type, the absolute viscosity of the type is, the absolute viscosity of the type is ~, the absolute viscosity of the type is ~. It is divided into No.ⅠⅡⅢ. The viscosity of No.Ⅰ paste is not greater than ,, the viscosity of No.Ⅱ paste is ~, and the viscosity of No.Ⅲ paste is ,~,. In 2001, the American Br company synthesized it and applied for a patent in the United States. and B r developed a plasticization method by adding various additives to make it a more flexible and easier-to-process material, which soon became widely used in commercial applications. The German French company uses emulsion polymerization to achieve industrial production of polyvinyl chloride. In 2001, Simon proposed that a high-boiling point solvent and tricresyl phosphate could be mixed with heat to process into soft polyvinyl chloride products. This was a real breakthrough in its practical application. The British Burnemann Chemical Industry Company, the American Union Carbide Company and the Goodrich Chemical Company almost simultaneously developed the suspension polymerization and processing applications of vinyl chloride. In order to simplify the production process and reduce energy consumption, the French company Saint-Gobain developed a bulk polymerization method. In 2017, the world's total consumption was approximately 10%, and its total production capacity was approximately 1% of the total plastic production. It is the second largest plastic variety after polyethylene production. China's self-designed production equipment was put into trial production at the Jinxi Chemical Plant in Liaoning in 2011. The equipment was officially put into industrial production in 2015, with an annual output of 100%.
In the first half of the year, affected by many unfavorable factors such as overcapacity in the industry and weak downstream demand, the overall performance of the PVC industry was poor and the company was in a difficult situation. However, the performance of the PVC foreign trade market is eye-catching, with many data showing significant restorative adjustments compared with the same period in previous years. However, industry insiders pointed out that as the operating rate of U.S. polyvinyl chloride factories increases, my country's polyvinyl chloride foreign trade is expected to show a recovery in import volume and a steady decline in export volume.
According to statistics from the China Chlor-Alkali Industry Association, as of the end of the year, the domestic polyvinyl chloride (fuzzy resin) production capacity was 10,000 tons/year. Among them, in the first half of this year, the new polyvinyl chloride production capacity was 10,000 tons/year, and the withdrawal was 10,000 tons/year, with a net increase of 10,000 tons/year. The withdrawn production capacity was all calcium carbide production equipment. The overall production capacity expansion rate of the industry has slowed down significantly, but the trend of steady growth in production capacity continues.
In terms of exports, my country's cumulative export volume of polyvinyl chloride in September increased significantly by 3% compared with the same period last year. From the perspective of flow direction, the largest export consumer market is India, and the number of goods exported to Russia has slowed down, ranking second.
In addition, since the outbreak of the financial crisis, the global market trade environment has undergone great changes. Trade protectionism has risen in various countries, and trade frictions targeting the products of Chinese companies have increased significantly.
