If you are in the fields of chemical engineering, pharmaceuticals or environmental protection, you will be dealing with filter presses and dust collectors every day. If the filter cloth is not chosen properly, either materials will leak or the equipment will get clogged. The work won't go smoothly and the cost will be high. Changzhou Xiahua Environmental Protection Technology Co., Ltd. has sorted out common scenarios to help you find the right one for yourself. 

1. Filter cloth for pressure filters and centrifuges: Want to discharge quickly and avoid slurry mixing?

Electroplating and pickling wastewater (highly acidic): Use polypropylene filter cloth, which is resistant to acids and alkalis, has a smooth surface, and the filter cake can easily fall off. There is no need to use a shovel to scrape it off piece by piece. 

Chemical products, pigments, ink (fine particles, sticky): Use nylon filter cloth. It has good stripping performance, is easy to clean the cloth, and is less likely to clog the holes. 

High-temperature materials (below 120℃): such as hot oil, resins. Use polyester filter cloth. It has a low shrinkage rate and maintains accuracy over a long period of use without deviation. 

The filter bags are prone to leakage of materials at the stitching edges: Xiahua Environmental Protection adopts double-needle lock stitching or hot melt technology, focusing on strengthening the bag opening and the connection between the ring, ensuring high pressure resistance without unraveling. 

II. Filter cloth for dust collectors: Want a clean outlet and no clogging of the bag?

Normal temperature dust (cement, ceramics, food processing): Ordinary polyester needle-punched fabric, with high cost-effectiveness. 

Coal grinding and chemical plant (with static electricity risk): Anti-static polyester filter cloth. Safety comes first. 

Boilers, waste incineration (120-180℃ flue gas): Aramid or PPS filter cloth, resistant to high temperatures and hydrolysis. 

High humidity and oil mist (such as from painting, drying exhaust): Coated filter cloth, smooth surface and does not stick to dust.
