Product Description

Filter Cloth for Press Filter Machine

Filter press cloth plays the role of filtering and separating solid-liquid mixtures in the filter press. Its quality and performance directly affect the working efficiency and filtering effect of the filter press. The filter cloth allows liquid to penetrate through tiny pores, while trapping solid particles on the surface of the filter cloth to form a filter cake. During the operation of the filter press, the filter cloth needs to withstand high pressure and have good water permeability and wear resistance to ensure a smooth filtering process.
 

 

There are various types of filter cloth for filter presses. Depending on different filtering requirements and operating environments, the weaving method, thickness, pore size and surface treatment of the filter cloth are different. Common types of filter cloth include plain weave filter cloth, twill filter cloth and needle-punched filter cloth. Plain weave filter cloth is suitable for general filtering needs, while twill filter cloth is more commonly used in high-precision filtering occasions because of its smooth surface and easy de-cake. Needle-punched filter cloth is made by needle-punching process, and its surface presents a fiber mesh structure. It has stronger air permeability and water filterability, and is suitable for filtering high-concentration solid-liquid mixtures.

Filter press filter cloth is usually made of synthetic fiber and natural fiber. Synthetic fiber is widely used in chemical, metallurgical, pharmaceutical and other industries due to its good chemical stability, acid and alkali resistance and strength. Polypropylene filter cloth is widely used in industrial wastewater treatment, chemical material filtration and other fields due to its acid, alkali and corrosion resistance. Polyester filter cloth has good wear resistance and high temperature stability and is often used for filtering high temperature materials. Natural fiber filter cloth is mostly used in food processing, pharmaceutical and other fields that require high material purity.
