Application range of aluminum sulfate

Aluminum sulfate is an inorganic substance with a chemical formula of Al2(SO4)3 and a molecular weight of 342.15. It is a white crystalline powder.

In the paper industry, it can be used as a precipitating agent for rosin glue and wax emulsion, as a flocculant in water treatment, as an internal retention agent for foam fire extinguishers, as a raw material for making alum and aluminum white, as a decolorizer for petroleum, as a deodorant, and as a drug. Raw materials, etc., can also produce artificial gemstones and high-grade ammonium alum.

The following is the detailed application industry of aluminum sulfate:

1. Used as a paper sizing agent in the paper industry to enhance the water resistance and anti-seepage performance of the paper;

2. After dissolving in water, the fine particles and natural colloidal particles in the water can be agglomerated into large flocs, which can be removed from the water, so it is used as a coagulant for water supply and waste water;

3. Used as turbid water purifier, precipitant, color fixing agent, filler, etc. Used as antiperspirant cosmetic raw material (astringent) in cosmetics;

4. In the fire protection industry, it can be used as a foam fire extinguishing agent with baking soda and foaming agent;

5. Analytical reagents, mordants, tanning agents, oil decolorizers, wood preservatives;

6. Stabilizers for albumin pasteurization (including liquid or frozen whole eggs, whites or yolks);

7. It can be used as a raw material for the manufacture of artificial gemstones, 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 also acts as a color-fixing and filling agent.
