The PTFE Technology Of Membrane Cracking Has Reached The International Advanced Level.

In September 27th, the China Textile Industry Association organized a strong expert appraisal committee in Shanghai, to Shanghai gold fluoride material Co., Ltd., Shanghai Ling Qiao environmental protection equipment factory and 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 has invented PTFE uniform solid processing technology, and has solved many technical problems such as micro pore control and uneven thickness in the process of membrane production by PTFE resin multiple mixing, multi-step compression and multi-channel stretching. 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 introduction, at present, the batch production of PTFE fiber products has

Ye Yongmao, senior engineer of China Chemical Fiber Industry Association, pointed out that the national development and Reform Commission has clearly listed the development and production of PTFE fibers and 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.
