(1) The filter material is made of high-quality polyester fiber. When the filter material is cleaned, the jitter is good, the dust is easy to peel off; the porosity is high, the gas permeability is good, the dust collection efficiency is high, and the service life is long; (2) high strength and low elongation industrial yarn is used as the base. Cloth, so that the strength is greatly improved; (3) PTFE impregnation, pore size reduction, high porosity, high filtration precision; (4) selection of superior polyester (polyester) fiber, acid and alkali resistance, hydrolysis resistance, wear resistance (5) PTFE immersion treatment of filter material improves water and oil resistance; (6) Suitable for working conditions with high humidity, low energy consumption and low maintenance cost; Iron and steel, cement, chemicals, power plants, iron alloy waste incineration, etc.
