It is very important to choose the right filter cloth
Filter cloth is an important filter elements of filter press, filter cloth is the filter medium of a filter press, that means that the filtration relay on filter cloth to realize. So, the importance of filter cloth goes without saying. Now let us learn together how to choose the filter cloth.
1, choose according to the shape of filter residue
According to the hardness of the particle in feeding materials to decide the wear resistance of the filter cloth. If the particle with high hardness and with non-uniform size, we should choose filter press with high wear resistance. Polyester filter cloth and acrylic fibers are with the best wear resistance.
2, according to the filtrate temperature
Temperature is a factor affecting the filter efficiency of a filter press China. If the filtrate with high temperature, we should choose filter cloth with high heat resistance-- Polyester filter cloth.
3, choose according to the viscosity of filtrate
The higher the viscosity, the lower the filter efficiency. So we should choose monofilament filter cloth or satin woven filter cloth when the filtrate with high viscosity.
4, choose according to acid and alkaline of filtrate
Depend on the acid and alkali of filtrate to choose suitable filter cloth. Polyester filter cloth has the strongest acid resistance and polypropylene filter cloth has the strongest alkali resistance.
If the filtrate with high acid as well as high alkali, we should choose the polypropylene fiber filter cloth which has a high acid resistance as well as high alkali resistance.
