The position and role of organofluorine materials, especially fluoroplastic resins, in chemical new materials are becoming more and more significant. The basic raw material is fluorite. Although China's fluorite reserves rank first in the world, China has implemented a permit system for fluorite exports since 1999, as it is a non-renewable resource. This has led to the famous foreign fluorine chemical companies have come to China to invest in new fluorine products deep processing projects, began to shift from the competition of China's fluorite resources to China's fluorine deep processing products.
The second phase of Dongyue project mainly includes 500 tons of perennial perfluorinated ion exchange resin and ion membrane project under the national '863' plan for major scientific and technological projects, and 20,000 tons per year of 40,000 tons per year of PTFE technical renovation and expansion project of the national key torch plan and 30,000 yuan. Ton/Year Dongyue Tsinghua Environmental Protection Refrigerant Technical Transformation and Expansion Project. All the above projects are planned to be completed within two years and will have a major impact on the organic fluorine materials industry in China. According to the prediction of experts, in 2007, the production capacity of PTFE in the world will reach 110,000 tons/year, and the PTFE scale of Dongyue will expand to 30,000 tons/year, ranking first in Asia.
As the first set of industrialization projects in China, the company has 500 tons per year perfluorinated ion exchange resin and ion membrane projects, mainly producing perfluorosulfonic acid resin and perfluorocarboxylic acid resin. The completion of this project will make China the third country that can produce perfluorinated ion exchange membranes after the United States and Japan. It will rewrite the situation that the ion membranes required for chlor-alkali industry's ion-exchange membrane caustic soda equipment will all depend on imports. China has made a contribution to the development of fuel cells in the world.
