For filter cloth, it is not only the wear and tear of the material itself that affects its service life, but more importantly, the corrosion of the filter cloth by the working substance. Therefore, the requirements for industrial filter cloth are very high, mainly having the following characteristics:
(1) The trapping effect of solid matter is good and the service life is long;
(2) Fast filtration speed, less clogging and stable filtration speed;
(3) The filter residue has good peelability, no expansion and contraction, and good dimensional stability.
