120-7 filter cloth is commonly used in industrial cloth models, the filter cloth made of polyester staple fiber. Acid products, resistance to weak base, the normal temperature <130 ℃.
120-7 filter cloth weave is twill, weighing more than 600g per square meter, belongs to the encryption filter cloth, the product is thick, strengthen the warp and weft to indicate the strength of the fabric to prevent the blockage of tissue residue to plug the leak, suitable for high precision The filter of the request.
Product detailed parameters are as follows:
Breaking strength (N / 5 * 20 cm): 4498/4044
Warp and weft density (root / 10cm): 256.4 / 212
Thickness (mm): 1.42
Weight (g / m2): 627.6
Air permeability (L / m2.s): 53.9
Fabric organization: twill
The choice of 120-7 filter cloth is very important to the filter effect. The filter cloth plays a key role during the filter press application. Its performance is good or bad, the selection of the correct or not directly affect the filtering effect. Currently used filter cloth is the most common is made of synthetic fiber textile filter, according to their different materials can be divided into polyester, vinylon, polypropylene, nylon and other several. In order to reach the retention effect and filtration speed are ideal, in the choice of filter cloth, but also needs to be based on the particle size of the slurry, density, chemical composition and filtration process conditions to choose. As the filter cloth in the weaving of materials, methods on the different strength, elongation, permeability, thickness, etc. are different, thus affecting the filtering effect. In addition, the filter media also includes cotton cloth, non-woven fabrics, screen, filter paper and microporous film, etc., according to the practice of filtration request.
