Low density large pore silica gel are milky white granules which are divided into lumpy(SG08) and spherical (SG09), among which there are two series each. The main composition is SiO2.nH2O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and concentrated caustic solution.
The products are mainly used as beer stabilization materials, or catalyzer carriers, they can also be used to adsorb macromolecule protein in zymolysis materials,to refine and purify vital materials, to cleanse water,to regenerate valuable metals,to separate and abstract effective substance from Chinese medicine materials or other compound medicines,to adsorb and separate gas from water resistance gels,etc.
Its technical specifications are shown in Table 5:
