Filter press cloth is designed for filter press filters. The filter plates and filter frames are arranged alternately, and the filter cloth is overlaid on both sides of the filter plates. It is mainly used in sludge dewatering, chemical, mining, food and other industries.
The main materials used for filter press cloth are polypropylene (PP), polyester (PET), and polyamide (PA), each offering different filtration performances:
1. Polyamide material is resistant to acids but not alkalis, has higher strength compared to other materials, has good abrasion resistance, it has excellent abrasion resistance properties.
2. Polyester material is resistant to acids and weak alkalis, with strength and abrasion resistance ranking just below nylon. It has good heat resistance and higher chemical stability but is susceptible to hydrolysis in strong alkalis.
Polypropylene material has strong acid and alkali resistance, excellent strength and abrasion resistance, and good chemical stability.
