Filter cloth is a filter medium woven from natural fibers or synthetic fibers. Commonly used materials include cotton, hemp, wool, cocoon silk, asbestos fiber, glass fiber and certain synthetic fibers. Such as cotton canvas, twill and woolen cloth. In a broad sense, filter cloth also includes metal mesh or filter mesh.
Filter cloth synthetic fibers mainly include polypropylene, polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, mainly for solid-liquid separation, while nylon is widely used in coal washing plants because of its excellent wear resistance.
The new high-efficiency filter cloth is mainly used in air filtration and dust removal, dust collection powder to purify the air and protect the environment. It is widely used in smelters, chemical plants, sugar, dyes, medicine, food and other industries.
Filter fabrics and screens made of polyester, polypropylene, nylon, vinylon, cotton and other materials are widely used in the pharmaceutical, chemical, dye, steel, construction, iron, chemical, ceramic, cement, geological, and mineral industries.
Special filter cloths include aramid, PTFE, PVDF, etc., with high operating temperature.
Filter cloth plays an important role in flue gas treatment and dust removal systems in ironworks, steelworks, ferroalloy plants, refractory plants, foundries, power plants, etc. Flue gas filtration for waste incinerators, coal-fired boilers, fluidized bed boilers, etc. Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites. Smelting flue gas filtration of aluminum electrolysis, lead, tin, zinc, copper and other rare metals, recovery of fine materials, separation of liquid and solid. Liquid-solid separation and fine material recovery in chemical, coke, carbon black, dye, pharmaceutical, plastic and other fields. Dust treatment and purification collection in mining, grain processing, flour, electronics industry, wood processing, etc.
