Industrial filter cloth is divided into woven fabric and nonwoven fabric. The washing filter cloth should be for sludge properties and particle sizes to select the filter cloth that can effectively intercept the sludge particles when it is filtered, mainly for the aperture size of the filter cloth and the water permeability (gas permeability), and the like. According to the pH value of the sludge, the filter cloth of the different material should be selected, and the polypropylene series filter should be used in an environment of pH 4 to 8, and the nylon series filter cloth should be used in the pH value of 4 to 8.5. Used in the environment. The environmentally friendly filter cloth is woven by natural fibers or synthetic fibers. Includes metal mesh or mesh. Mainly applied to air filtration and removal of dust, dustpage, to purify the air, protect the environment, in smelting plants, chemical plants, sugar, dyes, pharmaceuticals, food and other industries. The woven filter cloth includes a tabbling, twill and satin.

1. The weaving of the planar tissue mesh is to allow each weft to alternately float over each of the meridies, then sinking below the other moon. The web is not geometric deformation, the mesh is a square or a rectangle. The size of the hole is limited by the number of diameters or the root per unit length line.

2, the weaving method of the twill tissue filter is to alternately float over two meridians, then sinking below the two meridians. Form a twill pattern. The geometric deformation of the filter cloth is large, the wire and the latitude of the filter cloth and the latitude, and the network is irregular.

3, the method of satin weaving fabric is the number of warp (or weft) above the weft (or warp) float, and then alternately in this manner in this manner, for example, the loose aggregate of the fabric ( Such as nonwoven fabric and felt) control the thickness of the fiber layer, the pores and densities of the filter cloth. Such filters have irregular pore structures and large pores. If the surface is not heated, the filter mechanism is close to deep filtration. If appropriate heat treatment is used, the surface forms a high density and a small layer of aperture are small, and particles larger than the surface of the filter are smaller than the diameter of the filter, even if the particles are less than the diameter of the small hole, as long as the solid-liquid suspension is high There is a bridging and a filter cake is formed on the surface of the filter cloth, which is the same as the filter cake filtering.

The filter cloth industry is a highly competitive and high-risk industry. Practice has proved that whether developed countries or developing countries, the development of integrated circuit industry should adopt a centralized force, whether it is research and development or corporate production, it emphasizes cooperation rather than singing alone. Therefore, "anti-scatter" and "dispersion" are still our important work in the future.
