The polytetrafluoroethylene microporous membrane can be used for atmospheric dust removal, air purification and the like by utilizing the unique characteristics of node fibrillary property, smooth surface, chemical substance resistance, air permeability and water impermeability, large air permeability, flame retardance, high temperature resistance, strong acid and alkali resistance, non-toxicity and the like of the polytetrafluoroethylene microporous membrane. The product prepared by the membrane has high filtration efficiency up to 99.99 percent and is close to zero discharge; Low running resistance and high filtering speed; Long service life and can be repeatedly used, thereby reducing operation cost. It is mainly used for flue gas filtration of various industrial furnaces in chemical industry, iron and steel, metallurgy, carbon black, power generation, cement, garbage incineration, etc. Polytetrafluoroethylene filter membrane, the membrane pore size can be controlled in 0.2 ~ 15 μ m, porosity can reach more than 85%.

(1) The biggest characteristic of PTFE film material is high strength, medium strength ptfe film thickness is only 0.8mm, but its tensile strength has reached the level of steel; Moreover, the elastic modulus is lower, which is beneficial for the film material to form a complex curved surface modeling;

(4) Good self-cleaning, rain can wash out the surface of the attachments;

Is mainly used for filtering air suspended particles under 0.3um, as the end of a variety of filtration system filtration;

Has the advantages of high filtration efficiency, low resistance, large dust capacity, good uniformity of wind speed, strong versatility, convenient installation, etc.;

was founded in 2003 and transformed into the capital market in 2017. It is one of the first high-tech enterprises in the industry that provides technical solutions for air pollution control and treatment.
