As we all know, there are many different materials for the filter fabrics of filter presses, such as polyester filter cloths, polypropylene filter cloths, etc. The filter cloths are divided into various materials mainly to suit different filtrates, so Fontaine recommends that everyone choose The filter cloth is selected according to the filtrate. The specific selection method is as follows.
1, according to the filter acidity and other chemical properties to choose, different levels of acid and alkali to choose their own filter cloth type. The strongest acid resistance is polyester filter cloth, and the strongest alkali resistance is vinylon filter cloth. Acid and alkali resistance is also polypropylene fiber cloth.
2. The temperature and temperature of the filter are also a major factor affecting the working efficiency of the filter cloth in the filter press. The highest temperature resistant polyester filter cloth.
3. The stripping performance of the filter residue, which directly affects the working efficiency of the filter press equipment. The surface of the filter residue is smooth and inviscid, the filtrate will be rapidly leached out from the middle filter cloth, and the filtration efficiency is high. On the contrary, the filter residue has blocking properties and the filtration time will be long, and the efficiency will naturally be reduced accordingly. Moreover, the stronger the blocking, the lower the efficiency. In the case of this situation, monofilament or satin weave fabrics should be selected.
4, the shape of the filter residue, whether the particles are uniform, the shape is hard, so as to consider the abrasion resistance of the filter cloth. Uneven size, there are water chestnut, depending on the degree of choice. The best wear resistance is polyester filter cloth and polyester filter cloth.
According to your actual needs, the filter cloths selected by the filter press are more targeted. Not only the work efficiency is guaranteed, the filtering work can be completed well, and the use time is long, which greatly saves your use cost. I hope you can pay attention when choosing. This problem.
