Polyester anti-static membrane filter bag can be used in flue gas occasions with high humidity, high moisture content, high static electricity and high filtration accuracy. The surface layer of the filter bag is made of polyester fiber and needle punched with polyester + conductive fiber base cloth. The fiber has good flexibility and holding force, which can significantly improve the composite fastness, overall strength, anti-static and other properties of the filter material. The base cloth is made of conductive fiber. After pretreatment and heat setting, it has excellent physical and chemical indexes, stable size and high conductive performance. Compared with the ordinary filter bag, the filter bag after PTFE impregnation, eptef coating and other post-treatment improves the filtering accuracy of the filter material because the filter material is not easy to block the paste bag, the dust is conducive to stripping, and the dust emission concentration is low, so the dust purification efficiency is high and stable. The service life of the cloth bag is prolonged and the ash cleaning cycle can be prolonged, so it can save a lot of energy consumption and maintenance costs.
The temperature resistance grade of the product is moderate, the continuous working temperature is ≤ 130 ℃, and the instantaneous temperature resistance is 150 ℃.
The characteristics of polyester anti-static membrane filter bag are as follows:
(1) The filter material adopts high-quality polyester fiber, which has good jitter when cleaning the dust, and the dust is easy to peel off; High porosity, good air permeability, high dust collection efficiency and long service life;
(2) High strength and low elongation industrial silk is used as base cloth to greatly improve the strength;
(3) PTFE microporous membrane is used to reduce the pore size, high porosity and high filtration precision;
(4) Excellent polyester (polyester) fiber is selected to enhance the acid and alkali resistance, hydrolysis resistance and wear resistance of the filter material;
(5) PTFE impregnation and other post-treatment processes of the filter material improve the waterproof and oil proof performance;
(6) Suitable for working conditions with high humidity, low energy consumption and low maintenance cost;
(7) Conductive fiber is added to the base cloth of filter material to make the filter material have anti-static function
