The FMS needle felt is made of two or more kinds of high-temperature-resistant fibers mixed and layered and compounded by acupuncture, and has three-dimensional pore-forming high-temperature and high-efficiency filter materials. It is characterized by high temperature resistance, acid and alkali resistance, abrasion resistance, and flexural resistance. It has undergone various surface chemical treatment and post-finishing techniques, and is characterized by easy cleaning, water repellency and oil repellency. Iron and steel, smelting, ferroalloys, chemicals, cement, calcium carbide, waste incineration, electricity, asphalt mixing, etc. At the same time, the FMS needle felt has good heat resistance, flame retardance, low gas filter resistance and high dust removal efficiency. When the dust in blast furnace gas reaches a certain temperature or explosive limit, it can easily cause explosion and fire. In the field of bag type dust removal, These dust after the flue gas to be carried by the filter material, so the FMS needle felt in the production of stainless steel fiber or conductive fiber is added to make the FMS needle felt has conductive properties, so the FMS needle felt is used in the blast furnace flue gas concentration and The product of the place where the dust concentration is large is selected.
Compared with glass fiber needle felts, FMS needle felts have significantly improved abrasion resistance, bending resistance and peeling performance. They can bear high air volume, high concentration of dust, FMS needle felt and other synthetic fiber filter materials. In contrast, the FMS needled felt overcomes the characteristics of high elongation and low temperature resistance of the chemical fiber, and the FMS needle felt is cheaper than other high temperature resistant filter materials. At the same time, FMS needle felts are cheaper than NOMEX film filters because of their low price. They are ideal filter materials and are well received by users.
