1. Used as paper sizing agent in paper industry to enhance the water resistance and seepage resistance of paper;
2. After being dissolved in water, fine particles and natural colloidal particles in water can be condensed into large flocs, which can be removed from water, so it is used as coagulant for water supply and wastewater;
3. It is used as a purifying agent for turbid water, and also as a precipitant, color fixing agent, filler, etc. Used as an antiperspirant cosmetic raw material (astringent) in cosmetics;
4. In the fire protection industry, it forms foam extinguishing agent with baking soda and foaming agent;
5. Analytical reagents, mordants, tanning agents, oil decolorizers and wood preservatives;
6. Stabilizers for pasteurization of albumin (including liquid or frozen whole eggs, egg whites or egg yolks);
7. It can be used as raw materials to make artificial gem, high-grade ammonium alum and other aluminates;
8. In the fuel industry, it is used as a precipitant in the production of chrome yellow and lake dyes, and at the same time, it serves as a fixing agent and filler.
9. It is used as an effective cross-linking agent for animal glue and can improve the viscosity of animal glue. It is also used as curing agent of urea-formaldehyde adhesive, and the curing speed of 20% aqueous solution is faster.
