The filter cloth is softer and has lower strength, and the mesh of the lining mesh should be smaller in order to effectively support the filter cloth and smoothly discharge the filtrate. The filter cloth has satisfactory strength, suitable pore size and porosity, corrosion resistance to the material being treated, and certain wear resistance. There are three kinds of weaving method for the filter cloth, plain weave, twill weave and satin weave. The weave of the plain weave is the strictest, the twill weave is the second, the satin weave is the sparse, and the porosity is added sequentially. The
Cotton cloth
Excellent mechanical strength, wear resistance and temperature resistance, small pores, not affected by cold acid
Nylon filter cloth
High tensile strength, good abrasion resistance, lubricated appearance, convenient slag removal, resistance to most alkalis and organic acids at any concentration
Polyester filter cloth
Excellent strength and wear resistance, exceptional acid resistance, outstanding alkali resistance
Polypropylene filter cloth
Excellent wear resistance and temperature resistance, excellent corrosion resistance to inorganic acids, strong resistance to weak bases and strong alkali at room temperature, sulfuric acid in concentrations less than 80% is not dissolved
Nylon filter cloth
Corrosion resistance to alkalis and inorganic acids at room temperature, low price, but weak fiber, poor strength
PVC cloth
Concerning the strong acid at various concentrations and the concentrated alkali at higher temperatures, it has outstanding resistance to hunger, external lubrication, and easy to remove slag.
