Brief introduction of perlite filter aid products:
Perlite is a containing water of crystallization of silicic volcanic lava glass, belong to the igneous rock. Its particles by high temperature calcinations treatment, evaporation of crystal water in the rock, perlite to original volume 15, 20 times the proportion of rapid expansion, so the formation of rich in closed and open pores of the expanded perlite, after carefully grinding and winnowing, they formed with special properties of perlite filter aid.
