[0002] The filter cloth material is the "heart" of the filtration and separation equipment and is an important part that determines the separation effect. It plays a very important role in the chemical, pharmaceutical, metallurgical, food and other industries. However, due to the great differences in the properties of working materials in different industries and the complex use environment of the filter cloth, the uncertainty and complexity of the selection of filter cloth materials under different conditions are determined;

[0003] When the existing filter cloths on the market face high-intensity impact from waste liquid, the waste liquid carries large particles and impacts the filter cloth at high speed. The filter cloth has to face extremely high pressure. Ordinary filter cloths are not strong enough and are constantly impacted by industrial waste liquid during use. This can easily cause the filter cloth to tear, greatly affecting work efficiency. Utility Model Content

Since ordinary filter cloth is not strong enough, it is constantly impacted by industrial waste liquid during use, which can easily cause the filter cloth to tear, greatly affecting the work efficiency.
