Jinding Industrial Aluminum Sulfate

Thread Content

Aluminum sulfate products are manufactured from high-quality aluminum hydroxide, using advanced processing equipment and strict quality control measures to ensure excellence in production. This product features three key characteristics: high aluminum content, low iron content, and no free acids. The formula can also be adjusted or the quality standards can be changed according to the user’s requirements. The product is now exported to the United States and various countries in Southeast Asia, and is widely used in industries such as paste-based water purification and paper manufacturing, printing and dyeing, leather processing, wood protection, and fire-fighting agents. Especially in the papermaking industry, paper produced using this product is clean and flawless, with no discoloration over time. Physical and chemical properties: 1. Molecular formula: Al2(SO4)3·18H2O; 2. Appearance: white solid in block form; 3. Particle size: 15–20 mm. Technical specifications: These specifications were established in accordance with Standard Bureau Order No. 1983-07-01. Properties: This product is a white crystalline substance that is soluble in water but insoluble in alcohol. Its aqueous solution is acidic. The dehydration temperature is 86.5°C; when heated to 250°C, it loses its crystalline water. Anhydrous aluminum sulfate begins to decompose at 300°C, and at 860°C it decomposes into r-Al2O3, SO2, etc. The anhydrous form is a white crystal with a pearly luster. Uses: Mainly used in the production of high-grade paper brightening agents and sizing agents, as well as for post-coating treatment in the titanium dioxide manufacturing industry. It is also used as a sizing agent in papermaking, as well as a flocculant in drinking water, industrial water, and wastewater treatment ； Produces catalyst carriers, synthetic gems, and other aluminum salts. It is also widely used as an oil clarifier, a deodorizing and decolorizing agent for petroleum, and a concrete waterproofing agent. Packaging: The finished product is packaged in polypropylene woven bags with a plastic film lining, and the seams are sewn together using nylon or vinylon thread. The net weight per package is 50 Kg+_100g, or the packaging can be adjusted according to the customer’s requirements. Name: Al2O3%, Fe%, Water-insoluble matter%, pH value (1% aqueous solution), Specific gravity. Ordinary aluminum sulfate: ≥15.8, ≤0.30, ≤0.15, ≥3.0, 1.69; Iron-free aluminum sulfate: ≥16.0, ≤0.005, ≤0.10, ≥3.0, 1.69
