Description
Aluminum sulfate is mainly used as a papermaking sizing agent and a flocculant for drinking water, industrial water and wastewater treatment. It is also a raw material for the production of artificial gemstones and other aluminum salts, such as ammonia alum, potassium alum, and refined aluminum sulfate. In addition, aluminum sulfate is also widely used in the production of high-quality clarifiers, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, high-grade paper whitening, titanium dioxide post-film treatment and catalyst carriers.
In the papermaking industry, it is used as a precipitant for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, and as an internal agent for foam fire extinguishers. raw materials, etc. Artificial gemstones and high-grade ammonium alum can also be produced. Products with an arsenic content of no more than 5 mg/kg can be used as flocculants for water treatment.
1. Used as a 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 also serves as a color fixing and filling agent.
