Filter cloth material function: acid resistance, alkali resistance,  Wear resistance, corrosion resistance, recovery is very good, conductive function is very poor. Polyester fiber temperature resistance is generally 130-- 150℃, the product has the advantages of the general felt filter, and the wear resistance is very good, has a high cost performance and become the largest type of felt filter material. Mechanical function is the general term for the tensile function, wear-resisting function, elongation and elasticity of the filter cloth. Different filtration equipment has different requirements for the tensile function, wear-resisting function, elongation and elasticity of the filter cloth. When selecting filter cloth, the variety of filter cloth should be selected according to the type of filter.

Elongation reflects the ability of the filter cloth to allow deformation. If the filter cloth used by the van filter press and the plate and frame filter press has certain deformation, it requires that the selected filter cloth has better elasticity. The elasticity of the filter cloth can also be judged from the drawing curve of tensile force and elongation in the drawing process of the filter cloth. Cracking elongation is also one of the reference targets.

The wear resistance function is one of the objectives to reflect the life of the filter cloth. On some filtration equipment, although the tension of the filter cloth is small, there is certain friction between the filter cloth and some parts of the equipment or at the feeding port, which affects the service life of the filter cloth. If the scraper removes the filter cake, the periphery of the plate frame or van filter press and the inlet parts have certain friction, the filter cloth used in these devices requires good wear resistance.
