Aluminum Sulfate

Details:

Ammonium alum is an inorganic substance, which is soluble in water and glycerin, more soluble in boiling water, acidic in aqueous solution and insoluble in ethanol.The molecular formula is NH4Al(SO)2.12H2O.
Properties: 

Colorless glassy octahedral crystal to white particles or powder, odorless and slightly sweet, with strong convergence.
Features: 

High whiteness, high fineness, high content, no caking for a long time, which provides convenience for users to make and process.

Application:

1. Used as a paper sizing agent in the papermaking industry to enhance the water resistance and impermeability of paper;
2. After being dissolved in water, it can cause small particles and natural colloidal particles in the water to condense into
large flocs, which can be removed from the water. Therefore, it is used as a coagulant for water supply and wastewater;
3. Used as a turbid water purifier, as well as a precipitator, color fixative, filler, etc. Used as a raw material (astringent)
for anti sweat cosmetics in cosmetics;
4. In the fire protection industry, foam extinguishing agent is composed of baking soda and foaming agent;
5. Analytical reagent, mordant, tanning agent, oil decolorizing agent, wood preservative;
6. Stabilizers for albumin pasteurization (including liquid or frozen whole eggs, protein or egg yolk);
7. It can be used as raw material to produce artificial gemstones, high-grade ammonium alum and other aluminate;
8. In the fuel industry, it serves as a precipitator in the production of chrome yellow and lake dyes, while also serving as afixing and filling agent.
