Main performance of filter cloth:

1. Filter cloth as textiles, the main properties include: Raw material, tissue, yarn count, twist, density, square gram weight, breaking strength, breaking elongation, thickness, permeation rate (breathable amount), water permeation rate, etc. 

2. For the main properties of wet-type filtration: acid and alkali resistance, temperature resistance, minimum pore diameter, pore size distribution, regeneration performance, stripping performance, service life, etc. 

3. For the main properties of dry filtration: acid and alkali resistance, temperature resistance, minimum pore diameter, pore size distribution, air permeability resistance, dust removal efficiency, regeneration performance, service life, etc. 

4. Mainly used in liquid-solid separation, the main consideration is: raw material, tissue, yarn count, density, square gram weight, air permeability, thickness, rolling effect, simulated filtering effect, etc.

Raw material selection:

According to the different filtering environment, different raw materials are selected, mainly considering the properties of the raw materials themselves. 

1. Polyester: Acid Resistant and non-alkali resistance(PH value 1~10), continuous use temperature around 120°C, instant temperature up to about 150°C.

2. Polypropylene: acid and alkali resistant (pH 1~14), continuous use temperature 90°C, instant temperature around 120°C

3. Other raw materials also have their own advantages
