PTFE Membrane Dust Collector Filter Bag
PTFE (Polytetrafluorothylene) fiber and its composite non-woven needled felt filtration material Polyester film coated needled felt
The PTFE Membrane Dust Collector Filter Bag is made of PTFE (polytetrafluoroethylene) fiber, which has good chemical resistance, good low friction and good insulation. The unique three-dimensional mesh structure of the PTFE membrane makes it impossible for the dust to pass through, and there is no possibility of clogging of the pores. The PTFE membrane is not sticky and the coefficient of friction is small, the powder will fall off automatically, ensuring the long-term stability of the equipment resistance. It is a good filter material for bacteria removal and dust removal.
Advantages:
1) Can withstand the oxidation corrosion of various strong oxides, no hydrolysis reaction will occur at all
2) Has good filtration efficiency and good cleaning performance
3) Even at high temperatures, only a small amount of dust adheres to the surface
4) Under the same working conditions, the service life of filter media will be 1-3 times higher than that of other materials.
5) Good acid and alkali resistance and oxidation resistance, almost non-flammable
6) High air permeability, low resistance, good filtration efficiency, large dust holding capacity and high dust stripping rate
Application:
Coal-fired boiler, waste incineration, carbon black production, titanium dioxide (tio2) production, first metal smelting, chemical production, high sulfur coal dust removal
