Polypropylene fiber needle felt
Polypropylene fiber needle felt

Among the synthetic fibers, polypropylene is the lightest and easy to handle, has a temperature resistance of 90 ° C, and has good acid and alkali resistance. Therefore, it is applied to the fields of gas filtration and liquid-solid separation with temperatures below 100 ° C or strong acidity and alkalinity. In the field of liquid-solid separation, polypropylene needle felt is usually used together with liquid-solid separation equipment such as plate and frame filter press, vacuum suction filter, bag filter, centrifugal filter, etc., which not only has dimensional stability, high strength, low elongation, etc. The utility model has the advantages that the surface thereof is smooth and smooth, the whole has a gap, and the gas permeability is high, so that the filtration resistance is low and the dust is easy to be removed. Polypropylene needle felt can be used not only in steel, cement and other industries, but also as an ideal filter material for petrochemical, pharmaceutical, food and other industries.
