Pearlite is an acerbic, silicious, and vocalnic glass lava containing crystal water, falling into the category of igneous rock. After its particles incinerated by high temparature, crystal water in the rocks evaporates, and the pearlite expands sharply at the rate of 15 to 20 times, then forms into expanded pearlite rich in closed and open blowholes ,and then into GK-110 pearlite filter aids of special performance after being carefully grounded and winnowed.
The GK-110 pearlite filter aid is a kind of white solid powder composed of inert amorphous vitreum particles, whose main components are potassium, sodium, and aluminosilicate without peculiar smell and containing no organic substance in itself. Treatment of pearlite by high temparature in the process of production shall be upgraded to the effects of sterilization and elimination of organic substance ,therefore the GK-110 perlite filter aid with a very low solubility & strong chemical stability in organic acid and inorganic acid can not affact the color ,smell and taste of the filtrate .And its usage is completely the same as diatomite.
