INTRODUCTION
Polytetrafluoroethylene synthetic fiber filter bag is a filter bag made of a unique material, which can withstand acid and alkali erosion in the entire pH range under the continuous operating temperature of 240 °C and the instantaneous temperature of 260 °C. Polytetrafluoroethylene synthetic fiber filter bags are excellent in self-wetting, do not absorb moisture, and can withstand ultraviolet radiation.
Main features:
Polytetrafluoroethylene synthetic fiber filter bags can be used for flue gas treatment in coal-fired boilers, waste incineration, carbon black production, titanium dioxide (TiO2) production and other processes, and are also used in the primary smelting, refining and chemical production of some metals.
