In the process of chemical production, solid-liquid separation, impurity retention and process stability are the key links to determine product quality. As the core filter medium in the production process, industrial filter cloth, with its unique material properties and technological innovation, is bringing triple breakthroughs in efficiency, cost and environmental protection to the chemical industry.

First, corrosion resistance and high temperature resistance: reliable guarantee in the face of harsh conditions

Chemical production often involves extreme environments such as strong acids, strong alkalis, and high temperatures, which puts forward extremely high requirements for the stability of filter materials. Industrial filter cloth using polyester (PET), polypropylene (PP), PTFE (polytetrafluoroethylene) and other synthetic fiber materials, showing the following advantages:

Chemical stability: such as PTFE material can withstand the long-term erosion of strong acids (such as concentrated sulfuric acid), strong alkali (such as sodium hydroxide), to ensure stable performance in acid lye filtration, catalyst recovery and other scenarios;

High temperature adaptability: aramid (Nomex) and other materials can withstand temperature of more than 200℃, suitable for high temperature material liquid filtration after chemical reaction, to avoid filtration failure caused by material deformation;

Resistance to mechanical damage: The polyester coating process can improve the wear resistance, cope with the impact of sharp particles in the chemical slurry, and reduce the risk of damage to the filter cloth.

Second, accurate filtration and efficiency improvement: help product purity upgrade

The purity of chemical products directly affects the downstream application effect. Industrial filter cloth achieves precise separation through the following technologies:

Aperture control: A variety of specifications from 5 mesh to 2300 mesh (micron level accuracy) to meet different particle retention needs. For example, in the production of pharmaceutical intermediates, a 0.5μm precision filter cloth can effectively intercept microorganisms and particles to ensure that the liquid medicine is sterile;

Structural optimization: Flexible choice of plain, twill and satin weaving process, taking into account filtration efficiency and permeability. For example, the surface of the twill filter cloth is 45 degrees line groove, reduce the filter cake adhesion, improve the separation speed;

Intelligent adaptation: Customized filter cloth shape according to the characteristics of plate and frame filter press, centrifuge and other equipment, to achieve synergy between equipment and materials.
