Aluminum sulfate is an inorganic substance with the chemical formula Al2(SO4)3. It is a white crystalline flake, powder or colorless transparent liquid. In the papermaking industry, it can be used as a precipitant for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, as an internal agent for foam fire extinguishers, as a raw material for manufacturing alum and aluminum white, as a decolorizer for petroleum, as a deodorant, and as a pharmaceutical agent. Raw materials, etc. can also be used to produce artificial gemstones and high-grade ammonium alum.

Main categories: Industrial grade aluminum sulfate, iron-free aluminum sulfate, battery grade aluminum sulfate, reagent grade aluminum sulfate, ammonium aluminum sulfate/ammonium alum, potassium aluminum sulfate/potassium alum

Main uses of aluminum sulfate

1. Used as paper sizing agent in the papermaking industry to enhance the water resistance and anti-seepage properties of paper;
2. After being dissolved in water, it can aggregate the fine particles and natural colloidal particles in the water into large flocs, which can be removed from the water, so it is used as a coagulant for water supply and wastewater;
3. Used as a turbid water purifier, precipitant, color-fixing agent, filler, etc. Used as an antiperspirant cosmetic raw material (astringent) in cosmetics;
4. In the fire protection industry, it is used as a foam fire extinguishing agent with baking soda and foaming agent;
5. Analytical reagents, mordants, tanning agents, oil decolorants, wood preservatives;
6. Stabilizer for albumin pasteurization (including liquid or frozen whole eggs, egg whites or egg yolks);
7. Can be used as raw material for the manufacture of artificial gemstones and high-grade ammonium alum, and other aluminates;
8. In the fuel industry, it is used as a precipitating agent in the production of chrome yellow and lake dyes, and at the same time plays the role of fixation and filler.
9. Used as an effective cross-linking agent for animal glue and can increase the viscosity of animal glue. It is also used as a curing agent for urea-formaldehyde adhesives. The 20% aqueous solution cures faster.
10. Use it as a concrete waterproofing agent in cement, and you can also use it as an accelerator to speed up the solidification of cement.
