Industrial filter cloth is divided into woven fabric and nonwoven fabrics. The washing filter cloth should be for sludge properties and particle size 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 different materials 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 a filter medium from 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 smelter, chemical plant, sugar, dye, medicine, food and other industries. The woven filter cloth includes tabs, 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 woven filter cloth is in the case where there is no geometric deformation, the mesh is a square or a rectangle. The size of the bore is limited by the number of diameters or the root per unit length line.

2, the weaving method of the twill tissue cloth is that each weft yarn is alternately floating above the two meridians and then sinking below the two meridians. Form a twill pattern. The geometric deformation of the filter cloth is large, the wire and the weft of the filter cloth are long, and the network is irregular.

3, the method of satin weaving fabric is the number (or weft yarn) of the weft (or warp yarn) float, then in this way, alternately in this manner, such as a loose aggregate like a cloth ( 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 thin layer of small aperture, the particles larger than the surface of the filter are smaller than that of the particles are smaller than the diameter of the small hole, as long as the solid phase concentration in 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.

Horizontal vacuum with filter cloth, usually necessary before the sale. There are two commonly used finishing methods: heat treatment and calendering. The purpose of synthetic fiber heat treatment is to increase the stability of the filter cloth, making it more suitable for high temperature. The translator is a heat-proof filter cloth between the two hot roller by the high pressure roller to smooth the surface of the filter cloth smooth, smooth, and increase the removal of the filter cloth in use.
