Aluminum sulfate is an inorganic substance, the chemical formula is Al2 (SO4) 3, the molecular weight is 342.15, and it is a white crystalline powder.
In the paper industry, it can be used as the precipitator of rosin size, wax lotion and other sizing materials, as the flocculant in water treatment, as the retention agent of foam fire extinguishers, as the raw material for manufacturing alum and aluminum white, as well as the raw material for petroleum decolorization, deodorant and medicine, and also can be used to manufacture artificial gemstones and high-grade ammonium alum.
Main purpose
1. In the paper industry, it is used as a paper sizing agent to enhance the water resistance and impermeability of paper;
2. After being dissolved in water, the fine particles and natural colloidal particles in the water can be condensed into large flocs, which can be removed from the water, so it is used as a coagulant for water supply and wastewater;
3. It is used as a purifying agent for turbid water, as well as a precipitator, a fixing agent, a filler, etc. Used as raw material (astringent) for anti perspiration 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 bleaching agent, wood preservative;
6. Stabilizer of albumin pasteurization (including liquid or frozen whole eggs, albumen or yolk);
7. It can be used as raw material to manufacture artificial gemstones, high-grade ammonium alum and other aluminates;
8. In the fuel industry, it is used as a precipitator in the production of chrome yellow and lake dyes, as well as as a color fixation and filler.
9. It can be used as an effective crosslinking agent of 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 fast.
