Selection of Filter Cloth According to Filtrate
- Apr 22, 2019-
1. According to the acidity and alkalinity of the filtrate, choose the suitable filter cloth according to the different acidity and alkalinity. Polyester filter cloth has the strongest acid resistance and vinylon filter cloth has the strongest alkali resistance. Acidity and alkali resistance are also possessed by polypropylene filter cloth.
2. The temperature and temperature of the filter material are also a major factor affecting the working efficiency of the filter cloth of the press. The highest temperature resistance is polyester filter cloth.
3. The peeling performance of filter residue directly affects the working efficiency of plate and frame filter press equipment. The surface of the filter residue is smooth and non-sticky, and the filtrate will rapidly leach out from the filter cloth, so the filtration efficiency is high. On the contrary, the filter residue is cohesive, the filtration time will be long, and the efficiency will of course be reduced accordingly. And yes, the stronger the adhesion, the lower the efficiency. In this case, we should choose single filament filter cloth or satin fabric filter cloth.
4. Considering the wear resistance of filter cloth, the shape of filter residue, whether the particles are uniform or not, and whether the shape is hard or not. The size is uneven, and there are water chestnuts, according to the degree of choice. The best wear resistance is polyester filter cloth and warp filter cloth.
