The development trend of the world PVC market

 polyvinyl chloride (PVC) is one of the main varieties of general-purpose plastics. This product has good mechanical properties, chemical resistance, corrosion resistance and flame retardancy. It is a product with low energy consumption and low production cost

with the further internationalization of the market, the world PVC production has entered a new expansion period since 1997, and the total global production capacity has now increased to 27.7 million tons. Judging from the expansion of major companies in the world, the global PVC companies are now entering a new period of further monopolizing production capacity and expanding business scope, thus making the PVC market more international. For example, at the end of 1997, the U.S. Geon company merged the composite materials and liquid plasticization of Canadian synthetic industries in Ohio. 3. Hydraulic oil: you must always check the oil tank level and replenish oil in time; Generally, the oil should be changed every 2000 to 4000 hours of application; But the most important thing is that the oil temperature should not exceed 70 ℃. After the agent factory, its sales increased by 1.4 billion US dollars. Later, Giang company made strong alliances with Norwegian hydride company, Singapore SPC company and other companies, making its PVC production capacity reach 227000 tons, further improving the company's competitiveness in the world market

from a regional perspective, due to the impact of the financial crisis, Asian polyvinyl chloride 10. Displacement measurement accuracy: within ± 0.5% of the indicated value; The olefin market shrank from 1998 to 1999. After 2000, due to the economic recovery in Asia, this region has become the world's largest PVC market. The PVC market in Europe, Japan and the United States has basically maintained stable development in recent years

in terms of output, Taiwan, China is currently the largest PVC production area in the world, and PVC production in the United States, Japan and Western Europe also accounts for a large share in the world market. It is estimated that the total production capacity of PVC in the world will reach 32.355 million tons in 2001, and the output is expected to reach about 28.23 million tons

some experts in the industry predict that the annual growth rate of global demand for PVC in recent years is about 4.6%. In terms of regions, North America, Europe and Japan account for about 62% of the total global consumption, followed by China, South Korea and Southeast Asian countries

in terms of production technology, the global PVC production technology is constantly improving and improving. Recently, West Lake Company of the United States has improved the process and equipment for cracking 1,2-dichloroethane to produce vinyl chloride monomer, and developed a new quench tower and synthesis process, so that the gaseous logistics generated after the cracking of quenched dichloroethane does not need to use high-power circulating pumps and a large number of pipelines, which improves the benefits of the quench tower and solves the problems of safety and environmental protection. In addition, European ethylene company announced that in order to industrialize the process of oxychlorination of ethane to produce vinyl chloride, the company has developed a new catalyst. Using this catalyst, ethane can react directly to synthesize vinyl chloride at low temperature, and its cost is more than 50% less than that of the method of producing vinyl chloride from ethylene

at present, the production technology of PVC resin in developed countries in the world is relatively mature. Large kettle technology and advanced anti sticking kettle process are widely used, and the mixing and baffle are modified to improve the heat transfer capacity of the polymerization kettle. In addition, some large foreign companies have done a lot of work in the development of PVC special materials and products. It mainly includes vulcanizable thermoplastic elastomer crosslinked and blended with rubber, PVC wood like profile, PVC/wood composite window profile. In order to solve the problem of plasticizer migration of PVC products, Israel Weisman scientific research center has also developed a coating agent and its process to resist plasticizer migration, which not only solves the problem of plasticizer migration, but also extends the service life of PVC products. In addition, some American companies have also developed anti-static and anti γ- Polyvinyl chloride film and products of radiation. In order to make PVC leather richer in the texture of natural leather, Japan exiguang Petrochemical Company blended natural protein powder with PVC resin to make breathable imitation leather. In order to solve the problem of toxic gases released during the combustion of PVC plates and products, Showa chemical company of Japan added a special auxiliary agent with lithium carbonate as the main component during processing. When burning, lithium carbonate reacts with hydrogen chloride, preventing hydrogen chloride from accelerating the conversion of old and new kinetic energy, realizing transformation and upgrading, and providing important development opportunities for the new material industry. At present, this additive has been commercialized

in view of the current development trend of the international market, experts suggest that in order to adapt to the competition in the international market, domestic enterprises must focus on technological innovation and product development, further expand the production scale, increase the variety of PVC products, and reduce costs. At the same time, adopt flexible marketing mechanism, improve sales network and after-sales service, and expand market share. In addition, in view of China's large demand for PVC and large import volume, China should introduce advanced technology in the future, and build several sets of large-scale polyvinyl chloride, while fine particles will produce various new products of high and low polymerization degree and impact resistance copolymerization with olefin deposition devices in a long distance, so as to replace imported products
