Abstract

The invention relates to foaming microporous glass pumice for chemical clarification and water quality filtration. The pumice is characterized by comprising foaming micropores, wherein the aperture of the foaming micropores is 0.5-3mm, the water absorption is 15-30%, the strength is 3-8MPa and the density is 0.3-0.4g/cm<3>. The pumice is prepared by sintering a foaming mixture which comprises the following components in percentage by weight: 90-95% of glass powder, 2-5% of marble powder, 1-3% of aluminum oxide powder and 1-3% of calcite powder, wherein the fineness of glass powder is 40-100 mu m, the fineness of marble powder is 20-40 mu m, the fineness of aluminum oxide powder is 20-40 mu m and the fineness of calcite powder is 20-40 mu m. The invention further relates to a preparation method of the foaming microporous glass pumice for chemical clarification and water quality filtration. The pumice provided by the invention has the advantages of low using cost and long using period.
