The filter cloth is selected according to the filtrate.
For different filtrate, there are many different material filter cloth for your choice, the following are some simple selection method for reference:
1, According to the filtrate pH and other chemical properties to choose,
Different levels of pH choose their own kind of cloth, the most acidic resistance is polyester cloth, the most alkali resistance is PVA filter cloth. Both acid and alkali resistance is a polypropylene fabric.
2, The filtering temperature of the filter material,
the temperature is a major factor in the working efficiency of filter cloth,the highest temperature-resistant is polyester fabric.
3, Release properties of the residue, which directly affects the efficiency of the plate and frame filter press equipment.
Smooth surface without adhesive residue, and the filtrate will quickly removed out from the filter cloth, high filtration efficiency. On the contrary, adhesive residues, president of the filtration time, reduction in efficiency. the stronger the adhesive, the lower efficiency.
So for adhesive material filtering, we must choose the satin weave and silk fabric cloth.
4, The residues of shape, grain is uniform, whether rigid shape, so consider cloth wear resistance.
The most wear resistance is polyester filter cloth and dispensation filter cloth.
Depending on your actual needs to choose the filter cloth more targeted, guarantee the efficiency, and have a long use time, saving cost.
