Industrial Filter Cloth

The industrial filter cloth produced by Qingdao Star Machine can be customized. If necessary, we can provide samples free of charge.

The filter cloth should not be hung too loose or too tight, as being too loose can easily accumulate dust and being too tight can easily damage it.

New and old filter bags should not be mixed to avoid damage at different times that may affect the normal operation of the equipment.

The replaced filter cloth should be blown clean with compressed air first, and then checked for any holes. Any holes should be repaired and left for replacement. If the filter bag is covered with dust, rinse it with water, cool it dry, and leave it for replacement.

Product Parameter (Specification)

Product Feature And Application

1. Cotton Industrial filter cloth normal maximum continuous operating temperature is 180°F. Mainly used for vibrating screen collectors, general applications include: cleaning rooms, atmospheric cleaning, woodworking applications, cement and rock products, and other general applications for handling ambient air. Poor chemical resistance and high flammability. Cotton Industrial filter cloth have good chemical resistance under dry environmental conditions and are not recommended for use in the presence of mineral acids and oxidants. These filters have good resistance to bending and flat wear. Cotton has a good cleaning effect, and static electricity often fixes the dust cake on other fibers. Cotton has a flame retardant coating.

2.Polyester Industrial filter cloth normal maximum continuous working temperature is 275°F. Polyester felt has excellent chemical resistance, wear resistance, and dry heat degradation. Polyester is suitable for dry heat applications and is superior to synthetic materials other than aramid in this regard. Polyester is not suitable for humid and hot working environments, as in certain special circumstances, it may cause hydrolysis of polyester raw materials, thereby affecting the service life of filter fabrics. Except for high concentrations of nitric acid, sulfuric acid, and carbolic acid, polyester has good resistance to most mineral and organic acids. At the same time, it has good resistance to weak alkalinity and moderate resistance to strong alkalinity in low-temperature environments. Polyester also exhibits excellent resistance to most oxidants and organic solvents. But it is not recommended for certain phenolic compounds. It is not recommended to use high concentrations of strong alkali at high temperatures.

3.Polypropylene Industrial filter cloth normal maximum continuous working temperature is 170°F. Polypropylene felt is used in environments where chemicals and moisture corrode other fibers. Polypropylene has excellent properties of high strength and acid and alkali resistance. The smoothness of the fibers gives the filter cake good demolding and anti clogging performance. Polypropylene has good resistance to both mineral and organic acids, but is not suitable for environments with sodium hydroxide and potassium hydroxide above 200°F. It has good resistance to most reducing agents and also exhibits good tolerance to most organic solvents except ketones and esters.

4.Nylon Industrial filter cloth normal maximum continuous working temperature is 250°F. Nylon felt is commonly used in high abrasive dust applications. It has good alkali resistance under most conditions, but slightly poorer antioxidant properties. High concentrations and temperatures may lead to complete degradation. Nylon industrial filter cloth can withstand common organic solvents well.

5.Acrylic Industrial filter cloth normal maximum continuous working temperature is 275 ° F. Generally used for aluminum reduction and primary or secondary smelting. It has excellent acid resistance and is superior to polyamide and polyester in this regard. Acrylic acid is not as alkali resistant as most fibers. Acrylic acid has good tolerance to most oxidants. It has excellent tolerance to most common organic solvents. Acrylic acid as a whole has good acid resistance and high resistance to hydrolysis. Acrylic filter cloth is more expensive than polyester or polypropylene filter cloth.
