Polypropylene filter clothis polypropylene staple fiber, short fiber, spun yarn with wool; polypropylene long fiber, long fiber, formed yarn is smooth; polypropylene short fiber woven industrial cloth, cloth surface with wool, powder filtration and pressure The filtering effect is better than that of long fibers; the industrial cloth woven by polypropylene long fibers has a smooth surface and good air permeability.

Features of polypropylene filter cloth:

1. High temperature difference. The polypropylene material is not as good as polyester and other materials in terms of high temperature resistance. The normal working temperature should not be higher than 90 ℃, otherwise it will shrink slightly; the softening point temperature is 140-160 ℃; and the melting point temperature is: 165-173 ℃ ;

2, acid and alkali resistance. The polypropylene filter cloth has excellent acid and alkali resistance, and can be constructed in strong acid or strong alkali working conditions, and the acid and alkali resistance is 3-14;

3. The polypropylene material has a smooth surface, easy to remove cakes after post-processing, and has good air permeability.

Various styles and models of polypropylene filter cloth can be used with horizontal belt filter and vertical filter press, and the minimum fine filtration can reach 3-5μm; Deformation, strong regeneration ability of filter cloth, good air permeability; combined with ultrasonic edge sealing process, the edge of filter cloth is not easy to fall off.

Classification and use of polypropylene filter cloth

Filter cloth classification: polypropylene staple fiber filter cloth; polypropylene long fiber filter cloth.

Uses: Chemicals, ceramics, pharmaceuticals, smelting, manufacturing, mineral processing as filter bottoms.

The larger the filter cloth mesh number, the finer the material particle size; the smaller the mesh number, the larger the material particle size. The sieving particle size is the size of the sieve holes that the particles can pass through the screen. The specifications of standard sieves in different countries are different, which are called meshes.

For example, if the particles are -100 mesh to +200 mesh, it means that these particles can leak through the 100 mesh mesh but cannot pass through the 200 mesh mesh. When screening particles of this mesh size, the larger mesh ( 200) is placed under the screen with small mesh (100), and what is left in the screen with large mesh (200) is -100~+200 mesh.
