Through the efforts of several generations of fluorine chemical industry, China's fluorine chemical industry continues to grow. At present, there are thousands of domestic fluorine chemical enterprises, forming a complete fluorine chemical industry chain including fluoroalkanes, fluoropolymers, inorganic fluorides, fluorine-containing fine chemicals, fluorine material processing, etc., with an annual production capacity of more than 5 million tons and an annual sales volume of nearly 70 billion yuan, accounting for half of the world's production capacity and consumption.

China's fluorine chemical industry sprouted from the aluminum industry, starting from the inorganic fluoride salt. In March 1954, my country's first fluoride salt workshop was completed and put into operation in Fushun Aluminum Plant, which became the beginning of my country's fluorine chemical industry.

In 1964, the first set of 30 tons/year PTFE plant in China was completed in Shanghai Synthetic Rubber Research Institute, and the suspension PTFE resin was successfully produced. After that, the device tried to produce dispersed PTFE resin, which was officially put into production after being appraised by the former Ministry of Chemical Industry in 1965, ending the history of my country's inability to produce PTFE resin and becoming the first important development history of my country's fluorine chemical industry. milestone.

Before the reform and opening up, my country has achieved breakthroughs in fluoride salts, fluorine refrigerants, anhydrous hydrogen fluoride, polytetrafluoroethylene, fluorine rubber and other fluoropolymers and related products from scratch. After the reform and opening up, the production technology of all kinds of fluorine chemical products has made progress, and the overall technical level of the industry has also improved.

In 1984, the former Sixth Design Institute of the Ministry of Chemical Industry and the Shanghai Institute of Organic Fluoride Materials jointly developed a thousand-ton steam dilution cracking technology to produce PTFE, which realized the stable and large-scale production of PTFE.

In the late 1980 s, a number of private enterprises in Jiangsu and Zhejiang began to join the production of fluorine refrigerants and fluorine-containing aromatic intermediates. China's fluorine chemical industry also began to develop high-end fluorine products such as perfluorinated ion exchange membranes, soluble polytetrafluoroethylene, fluorine resin F40, perchlorofluorocarbons and Halons substitutes. By the end of the 20th century, the research on fluorine-containing fine chemicals in China was extremely active, and more than 100 kinds of fluorine-containing fine chemicals including fluorine-containing intermediates and fluorine-containing surfactants of drugs and agricultural chemicals have been developed.

In the 21st century, China's fluorine chemical industry has also begun to change from large to strong. The level of production technology has been rapidly improved, and new breakthroughs have been made in polymer technology and engineering amplification technology. Major PTFE production enterprises such as Shandong Dongyue, Sichuan Chenguang, Shanghai Sanaifu, Jiangsu Meilan and Zhejiang Juhua have appeared in China, making China the world's largest producer of PTFE. At the same time, the scale of fluorine rubber device has also been rapidly expanded, powder fluorine rubber, low Mooney viscosity fluorine rubber, high-speed extrusion grade F46 resin, battery adhesive with polyvinylidene fluoride and other new products have been launched. The expansion of the scale of fluorine resin and fluorine rubber has made my country the world's second largest producer and marketer of fluorine polymers.

However, with the rapid development of fluorine chemical industry, domestic enterprises also realize that with the gradual reduction of high-grade fluorite resources in China, it is imperative to develop and utilize low-grade fluorine resources and develop fluorine resource recycling economy. Since 2002, Duofluoroduo Company, Zhejiang Hansheng Fluorine Chemical Co., Ltd., Guizhou Wengfu Lantian Chemical Company and other enterprises have successively started to use low-grade fluorite or by-product fluorine resources to prepare anhydrous hydrogen fluoride to realize comprehensive utilization of resources.

On March 23 this year, Baotou Iron and Steel Co., Ltd., Jinshi Resources, Longda Food Group Co., Ltd. and Zhejiang Yonghe Refrigeration Co., Ltd. held a signing ceremony for the fluorite resource joint venture and cooperation project in Baotou, which means that 0.13 billion tons of fluorite resources in the Baiyun Obo Mine in Inner Mongolia After sleeping for more than 60 years, large-scale industrial utilization was officially started. Upon completion, the project will produce 800000 tons of fluorite annually, forming the world's largest fluorite fluorine chemical production base. The project will also fully recover fluorite resources, transform resource advantages into huge economic advantages, and ensure the sustainable and stable development of fluorite, a strategic resource.

At present, a number of fluorine chemical parks with world influence have been built, a number of outstanding enterprises are also gathered in the park, and the industrial concentration of the domestic fluorine chemical industry is constantly increasing. In the recently announced list of the top 30 chemical parks in China, a number of fluorine chemical industry parks are on the list.

In the fluorine chemical industry, state-owned, private and foreign enterprises have also formed a competitive situation. Private enterprises such as Dongyue, Duofuduo, Liwen, and state-owned enterprises such as Meilan have developed rapidly under the vitality of strong systems and mechanisms; state-owned enterprises such as Juhua, Sinochem Blue Sky, and Sanaifu still maintain strong Competitiveness; while foreign companies such as Chemo, 3M, ACG, Suwei, Daikin, and Arkema control the high-end market with obvious advantages. Fluorine chemical industry has become an important part of China's strategic emerging industries, which is of great significance to promote the structural adjustment and product upgrading of China's manufacturing industry.

In order to change the situation that my country's fluorine chemical industry has been at the low end of the industrial chain, low added value of products and some high-end products rely on imports, in recent years, my country's fluorine chemical industry has also made a lot of efforts to move towards the high end of the industrial chain and replace foreign products. In terms of fluoropolymers, several leading domestic companies have begun to become stronger, more detailed, refined, and specialized, and have begun to replace foreign products in local and some international markets, forming a direct competition with them. A number of independent innovative scientific and technological achievements are catching up with western developed countries, such as Dongyue Group and Shanghai Jiaotong University to jointly overcome the industry problem of chlor-alkali ion-exchange membrane, as well as the control of hydrogen fuel cell membrane technology.

Wang Xiaofeng, president of the China Inorganic Salt Industry Association, said that the double-cycle development model has brought opportunities for the industrial upgrading and high-quality development of the inorganic salt industry. During the "14th Five-Year Plan" period, my country's fluorine chemical industry should attach great importance to independent innovation and promote structural adjustment. Industrial upgrading focuses on the continuous and stable supply of resources, improving enterprise innovation capabilities, safety and environmental protection levels, and enterprise vitality, guide enterprises to develop in the direction of collectivization, scale, high-end, green, intelligent, and internationalization, accelerate the construction of a double-cycle new development pattern, seek breakthroughs through innovation, and continue to promote the high-quality development of the industry.
