The fluorine United States Sri Lanka filter needle felt, FMS products have the characteristics ofhigh-temperature, high-strength, anti-acid corrosion, wear, bending, etc., after different surface chemical treatment and finishing techniques, also having easy cleaning, water repellent and oiltheantistatic function; series of products for different temperature ranges of 150-200 ℃ ,200-250 ℃ ,250-300 ℃.
    Filter with glass fiber filter FMS fluorine Mei Si compared to its wear resistance, fracture resistance and peel strength, can bear high filtration load, the filtration rate of up to 1.5 m / min or higher, running resistance is low. Compared to high temperature synthetic fiber filter media to overcome the the fiber filter elongation, large deformation, low temperature, poor corrosion resistance weaknesses; dimensional stability, strength, better, and cheaper prices in other high-temperature chemical fiber.
    FMS fluorine U.S. Andean filters is the development of new products for China’s national conditions, widely used in iron and steel, nonferrous metal smelting, chemical industry, building materials, electricity and other departments, the use of a large amount of several performance the following table:
