Stereo drawing machine processing technology for the preparation of membrane technology

Drafting machine the appraisal expert committee is a strong lineup, appraisal committee director and deputy director were ensembles by three academician of the sun Jinliang, Jiang Shicheng, Zhang Yaoming, from chemical fiber materials, industrial textiles, environmental protection, chemical industry and other fields of 11 renowned experts agreed that the project is in China in terms of high performance fiber processing technology, production equipment, product development of major integrated innovation, with a demonstration effect, the overall technology has reached the international advanced level.

Experts in the expert opinion that uniform PTFE stereo processing of membrane technology was invented by the project, independent research and integrated innovation of PTFE membrane and fiber special complete production equipment, stable operation, has formed a kiloton production capacity. The scientific research results have the independent intellectual property rights, the patent application for invention patents 10, has authorized 4, social and economic benefits, the market application prospect is broad.

China Chemical Fiber Industry Association, advisor, professor level senior engineer Ye Yongmao told reporters: "the national development and Reform Commission in the" catalogue for the guidance of industrial structure adjustment "in this year will indeed PTFE fiber and its products development and production are classified as one of the key, in the" Twelfth Five Year Plan "at the beginning of the year, to the completion of the project unit series of fruitful results, exciting." PTFE fiber as skeleton material with excellent performance and its batch production to promote the application of Aramid 1313, Fang PSA, polyphenylene sulfide fiber high performance fiber in the filter on, can accelerate the transformation of economic development mode of China's chemical fiber industry and to promote the upgrading of the chemical fiber industry structure adjustment and optimization, improvement and development of the modern industrial system.

Ye Yongmao introduced the split film production of PTFE fiber and its applications, including PTFE long fiber and PTFE short fiber, PTFE long fiber developed products include: long fiber yarn, PTFE sewing thread, PTFE ethylene dental floss, chlor alkali project special PTFE long fiber reinforced net, and using PTFE fiber production of PTFE Vinyl Fabrics, PTFE laminated needled felt filter material such as. The production of PTFE, short fiber products technology is in the international advanced level, the product price is about 35% of foreign similar products, greatly reducing the production cost of domestic users, for China's environmental protection batch application of high performance PTFE fiber laid the foundation.

Ideal material for dust removal filter material

China Electric Power Research Institute of environmental protection dust removing ash, director of the Institute, professor level senior engineer Fang Aimin said: "domestic PTFE fiber production technology is a major breakthrough, succeeded in breaking the years foreign to our products Monopoly and technical blockade, will lead to environmental protection technology and materials for the upgrade, promoting the 'blue sky project' the key stage in the" Twelfth Five Year Plan "national, is of great social significance, has made significant economic benefits.

According to Fang Aimin introduced, the project product PTFE fiber is an important application of the preparation of high temperature corrosion of flue dust with PTFE filter media. Now, domestic PTFE filter material has been widely used in waste incineration, coal power plant, iron and steel industry and other industries, is China's key materials to achieve energy saving and emission reduction, and PTFE filter material can also be used in the field of gas and solid two-phase separation in high temperature environment, as a filter material.
