(Scope of application reference ‘product usage’)
It can be prepared by the pressure reaction of bauxite and sulfuric acid, or by the decomposition of alum stone, kaolin and alumina containing silicon raw materials with sulfuric acid. The bauxite is pulverized to a certain particle size by sulfuric acid method, and the reaction kettle is added to react with sulfuric acid. The reaction liquid is settled, and the clarified liquid is added to sulfuric acid to neutralize to neutral or slightly alkaline, and then concentrated to about 115℃. After cooling and curing, the finished product is crushed.

Product Usage
Main use
1. Used as paper sizing agent in the paper industry to enhance the water resistance and impermeability of paper;
2. soluble in water can make the fine particles in water and natural colloids condensed into large flocculent, so removed from the water, so used as water supply and wastewater coagulant;
3. used as turbidity water purification agent, also used as precipitating agent, fixing agent, filler and so on. It is used as raw material (astringent) in cosmetics to suppress perspiration;
4. in the fire industry, with baking soda, foaming agent to form foam extinguishing agent;
5. analytical reagents, mordant, tanning agent, oil decolorizing agent, wood preservatives;
6. albumin pasteurization stabilizer (including liquid or frozen whole eggs, white or yolk);
7. can be used as raw materials for the manufacture of artificial gems and high-grade ammonium alum, other aluminates;
8. in the fuel industry, in the production of chromium yellow and color lake dye as precipitating agent, but also plays the role of solid color and filler.
9. used as an effective crosslinking agent for animal glue, and can improve the viscosity of animal glue. It is also used as the curing agent of urea-formaldehyde adhesive, and the curing speed of 20% aqueous solution is faster.
