Silica Use and Manufacturing

Methods of Manufacturing

Mix the aqueous solution of water glass with dilute sulfuric acid, gel at 20～30℃ under a certain pH value, use 2%～2.3% sulfuric acid solution to soak for 3～5h at 25～30℃, use 55～65 Wash at ℃ to acid content (4～6)×10. Then, remove it with a sieve and dry it to a water content of ≤10%. After screening, dry it to a water content of ≤2%.

Uses

manufacture of glass, water glass, refractories, abrasives, ceramics, enamels; decolorizing and purifying oils, petroleum products, etc.; in scouring- and grinding-compounds, ferrosilicon, molds for castings; as anticaking and defoaming agent.
