PPS (polyphenylene sulfide) antistatic needle felt filter bag

PPS (polyphenylene sulfide) antistatic needle felt filter bag is made of high-quality PPS (polyphenylene sulfide) fiber produced by Japan Toray company or Japan Toyo textile. The filter material is implanted with conductive fiber to make the filter material have antistatic performance. It is produced by our mature needle technology and German host equipment, plus effective post-treatment process, so that most fiber surfaces are protected by nano coating, It not only greatly reduces the possibility of oxidation and corrosion of PPS (polyphenylene sulfide), but also realizes a qualitative breakthrough in filtration accuracy. The filter material is treated by PTFE (polytetrafluoroethylene) membrane, so that the micropores on the surface of the membrane coated filter material are small and uniform (0.10-2.0 μ m) , it can separate all the dust larger than the micropore diameter, and the capture rate of PM10 (respirable dust) and PM2.5 (respirable dust) seriously damaging human health can reach 100%. It is easy to meet the emission requirements under working conditions.
PPS (polyphenylene sulfide) antistatic filter bag has the following characteristics:
PPS (polyphenylene sulfide) anti-static needle felt coated filter bag combines the advantages of PPS (polyphenylene sulfide) fiber, conductive fiber and PTFE (polytetrafluoroethylene) polymer material, overcomes the shortcomings of single material, and makes a new composite filter material with high performance, high cost performance and anti-static performance.
a. The surface layer of the filter bag is blended with PPS (polyphenylene sulfide) fiber + conductive fiber and needle punched with high-performance PTFE (polytetrafluoroethylene) base cloth. The composite fiber has good flexibility and holding force, which can significantly improve the composite fastness and overall strength of the filter material. Due to the addition of conductive fiber, the filter bag has anti-static function.
b. The filter bag base cloth is made of high-quality and high-strength PTFE (polytetrafluoroethylene) fiber and woven into high-strength PTFE (polytetrafluoroethylene) base cloth to ensure that the filter material has sufficient mechanical strength; After pretreatment and heat setting processing, high-performance PTFE (polytetrafluoroethylene) base cloth with excellent physical and chemical indexes and stable size is made.
c. Post treatment process
After the composite filter material is made, the unique post-treatment production process of our company and the unique "polytetrafluoroethylene (PTFE) mixed solution" are used to conduct overall singeing, calendering, PTFE (polytetrafluoroethylene) impregnation and other post-treatment for the post-treatment formula of the current working condition. The filter material is then sintered at high temperature to wrap a layer of PTFE (polytetrafluoroethylene) film on the fiber surface, The characteristics of the composite fiber are organically combined with the characteristics of the mixed lotion, such as temperature resistance, corrosion resistance, good flexibility, easy ash removal, etc., to greatly improve the oxidation resistance, corrosion resistance, temperature resistance and dimensional stability of the filter material, enhance the hydrophobicity of the filter material, improve the filtering accuracy of the filter material, and extend the service life of the filter material. PTFE (polytetrafluoroethylene) membrane is formed on the surface of the filter material after the filter material is coated with PTFE (polytetrafluoroethylene), and the membrane hole is small and uniform (0.10-2.0 μ m) , it can separate all the dust larger than the micropore diameter, so the dust purification efficiency is high and stable.
