P84 compound needle felt filter bag combines the high strength of glass fiber, P84 fiber with high filtration precision and wear resistance, overcomes the shortcomings of single material, and makes high-performance, cost-effective new composite filter material. The surface layer of P84 compound needle felt filter bag is selected with P84 fiber + alkali-free glass fiber and high-performance glass fiber base cloth. The fine fiber has good flexibility and cohesion, which can significantly improve the compounding of filter material. Fastness and overall strength, the surface of the fiber is wrapped to form a PTFE protective film, which greatly improves the oxidation resistance, corrosion resistance, temperature resistance and dimensional stability of the filter material; enhances the water repellency of the filter material, improves the filtration precision of the filter material, and prolongs The service life of the filter material is applicable to carbon black steel, cement, chemical, power plant, iron alloy waste incineration, etc. according to industrial and mining requirements.
