Yingkou Gongyuan Environmental Protection Filter Co., Ltd.

Aramid needle felt filter bag has excellent performance of its own material and enhanced production process. It has good jitter during cleaning, dust is easy to peel off, and the required cleaning pressure is small, the number of cleaning times is small, and the consumption of compressed air is effectively reduced. Maintenance volume and saving operating costs. Aramid needle felt filter bags are also not affected by special powders and gases, and have very good applicability. Intrinsically flame-retardant fiber; does not self-ignite or does not support combustion, even if it ignites, it will self-extinguish after removing the flame; it will not suddenly soften like ordinary thermoplastic fibers, and combustion will not produce droplets. Aramid needle felt filter bag has outstanding corrosion resistance. Aramid fiber has stable chemical structure, can resist most high-concentration inorganic acid, has good alkali resistance at normal temperature, and is stable to other chemical reagents and organic solvents. Moreover, after the whole filter material is immersed by PTFE, it can resist the corrosion of corrosive substances such as various acids and alkalis, and the base fabric is not corroded in use. The aramid needle felt filter bag is PTFE impregnated to enhance the hydrophobicity of the filter material. The PTFE emulsion impregnation makes the surface of the filter material smooth and the friction coefficient is low, which eliminates the adsorption of water by the filter material and effectively reduces condensation. After the knot phenomenon. According to industrial and mining requirements, carbon black steel, cement, chemical, power plants, iron alloy waste incineration, etc. are applicable.
