Filter cloth is made of natural fiber or synthetic fiber woven filter medium. Commonly used materials are cotton, hemp, wool, cocoon silk, asbestos fiber, glass fiber and some synthetic fibers. Such as cotton - woven canvas, twill and woollen cloth, etc. In a broad sense, press cloth also includes metal mesh or strainer.

The main synthetic fibers of filter cloth are polypropylene, polyester, nylon, Vinylon, etc., among which polyester and polypropylene are the most commonly used, mainly for solid-liquid separation, and nylon is widely used in coal washing plants, because of its excellent wear resistance.

New high efficiency filter cloth is mainly used in air filtration and dust removal, dust collection powder, to purify the air, protect the environment, widely used in smelters, chemical plants, sugar, dye, medicine, food and other industries.

Polyester, polypropylene, nylon, Vinylon, cotton and other materials of filter cloth, screen, are widely used in pharmaceutical, chemical, dye, steel, construction, iron metallurgy, chemical, ceramics, cement, geology, minerals and other industries.

Special filter cloth: aramid, PTFE, PVDF and so on, the use of high temperature.

The press cloth plays an important role in the flue gas treatment and dust removal system of ironworks, steel mills, ferroalloy factories, refractory factories, foundries and power plants. Waste incinerator, coal-fired boiler, fluidized bed boiler and other flue gas filtration. Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites. Aluminum electrolysis, lead, tin, zinc, copper and other rare metals smelting flue gas filtration, fine material recovery, liquid, solid separation. Chemical industry, coke, carbon black, dyes, pharmaceuticals, plastics and other fields of liquid-solid separation and recovery of fine materials. Dust control and purification collection in mining, food processing, flour, electronics industry, wood processing, etc.

In general, needle felt is selected for pulse jet bag dust generator, and woven fabric is selected for chamber reverse blowing bag dust collector or mechanical vibration bag dust collector. If the working condition is high temperature, acid and alkali resistance and humidity can be used in high temperature, such as coated flumez, etc., there are many factors to consider in choosing dust bag.

1. According to the shape of cross section of dust removal filter bag, it is divided into flat bag (trapezoid and flat plate shape) and round bag (cylindrical shape).

2. According to the air inlet and outlet mode, it can be divided into: downward air inlet and upward air outlet and upward air outlet and straight flow (only limited to flat plate bag).

3. According to the filtration method of dust removal filter bag, it is divided into external filter type and internal filter type.

4, according to the temperature bearing capacity of dust filter bag is divided into: high temperature type, medium temperature type, normal temperature type.

5, application field Application field: ironworks, steel mills, ferroalloy factory, refractory factory, foundry, power plant, cement factory, chemical plant, grain processing plant, carbon black factory, aluminum factory, etc.
