The industry association has organized a strong expert appraisal committee in Shanghai, and has made technical achievements appraisal on the project "industrial production technology and Application Research of membrane cracking polytetrafluoroethylene (PTFE) fiber", jointly completed by Shanghai gold fluorine materials Co., Ltd., Shanghai Ling Qiao environmental protection equipment works Co., Ltd. and General Logistics Department of the PLA General Logistics Department.

Academician Sun Jinliang, deputy director of the appraisal committee, academician Jiang Shicheng and Zhang Yaoming, and 11 experts from the fields of chemical fiber materials, industrial textiles, environmental protection, chemical industry and other fields believe that the project is a major integrated innovation in terms of processing technology, production equipment and product development of high-performance fibers in China, with demonstration effect and overall technology reaching the international advanced level.

The project invented PTFE uniform solid processing membrane technology, after PTFE

Multiple mixing, multi-step compression and multi-channel stretching process have solved the technical difficulties in controlling membrane thickness and uneven thickness in the process of membrane production. The temperature gradient controlled non isothermal, variable width, multi-channel stretching, split fiber and other production technologies have improved the strength and density uniformity of PTFE fiber produced by the membrane splitting method. A series of high-performance filter materials have been developed by compounding with the expanded polytetrafluoroethylene (ePTFE) film by hot pressing.

Independently developed and integrated innovative PTFE membrane and fiber complete sets of production equipment have been operating steadily, forming a thousand ton production capacity.

The product has 10 independent intellectual property rights, applied for invention patents, and has been authorized 4. The social and economic benefits are significant and the market prospect is broad.

According to the introduction, the PTFE fiber products produced by batch production have the characteristics of high temperature resistance, strong acid and alkali corrosion resistance, and stable performance under harsh conditions. They have been successfully applied in the fields of refuse incineration, coal-fired power plants, steel and cement, and achieved good results.

The quality of its products is comparable to that of the developed countries. Some of its products even exceed foreign products, and the price is only 1/3 of foreign products. Some products have been exported to developed countries in Europe and the United States.

Ye Yongmao, senior engineer of the industrial association, pointed out that the NDRC has clearly listed the development and production of PTFE fiber and its products in the guidance catalogue of industrial restructuring.

In the first year of 12th Five-Year, it was heartening to see that the completion of the project completion unit was fruitful.

PTFE fiber as an excellent skeleton material, its mass production can promote the application of high performance fiber such as aramid fiber 1313, polysulfonamide fiber and polyphenylene sulfide fiber on filter material. It can accelerate the pformation of China's chemical fiber industry's economic development mode, promote the adjustment and upgrading of chemical fiber industry structure, and improve and develop the modern industrial system.

Fang AI min, director of the Institute of dust removal and ash removal, State Grid Environmental Protection Research Institute, said that a breakthrough in the production technology of domestic PTFE fiber has successfully broken the monopoly of foreign products and technological blockade in China over the years, which will lead to upgrading of environmental technology and materials. It has great social significance and economic benefits in the key stage of the "blue sky project" in 12th Five-Year.
