Solid Indicators: Implement National Standard HG/T2225-2001 Main production and operation: Ordinary aluminum sulfate, iron-free aluminum sulfate, liquid aluminum sulfate, and other series products

Aluminum oxide ≥15.6 Iron ≤0.20 Water-insoluble matter ≤0.10 pH value ≥3.0
Specific gravity 1.69
Properties: Iron-free aluminum sulfate is a white crystal with a specific gravity of 1.69, easily soluble in water, insoluble in alcohol, forming an acidic aqueous solution. Dehydration temperature is 860°C, loses crystal water when heated to 250°C. Anhydrous aluminum sulfate begins to decompose at 300°C and decomposes into γ-Al?O?, etc., at 860°C. The anhydrous form is a white crystal with a pearly luster.
Applications: Mainly used in the manufacturing of high-grade paper and as a sizing agent, for post-coating treatment in titanium dioxide production. Also used as a paper sizing agent and flocculant for drinking water, industrial water, and wastewater treatment. Used in the production of catalyst carriers, artificial gemstones, and other aluminum salts. Widely applied as a fat clarifier, deodorizing and decolorizing agent in petroleum, concrete waterproofing agent, and raw material for rainproof fabrics.
