Description:
Aluminum sulfate (chemical formula Al2(SO4) 3, formula weight 342.15), white or thorhombic crystal powder, density1.69g / ㎝³ (25 ° C), About 50% of the total output of aluminum sulfate is the first major use for papermaking, the second largest use is in drinking water, industrial water and industrial wastewater treatment as flocculants, accounting for about 40% of the total output of aluminum sulfate. When aluminum sulfate is added to this type of water,colloidal aluminum hydroxide flakes can be formed that can adsorb and precipitate bacteria, colloids and other suspended matter, and can be used to control the color and taste of water in drinking water treatment.
Application:
1. Paper industry used as a paper sizing agent to enhance the paper's water, impermeability;
2. Dissolved in water can make the water in the small particles and natural particles condensedin to large pieces of floc, and thus removed from the water, it is used as water and wastewater coagulant;
3. Used as a turbid water purifying agent, also used as a precipitating agent, fixing agent, fillerand so on in cosmetics as antiperspirant cosmetics raw materials (astringent).
4. Fire industry,with baking soda, foaming agent composed of foam fire extinguishing agent;
5. Analysis reagents, mordant, tanning agent, oil decolorizer, wood preservative;
6. Albumin pasteurization stabilizer (including liquid or frozen whole egg, protein or eggyolk);
7. Can be used as raw materials for the manufacture of artificial gemstones and higher ammonium alum, other aluminates;
8. In the fuel industry, in the production of chrome yellow and lake dye as a precipitant,while the role of fixing and filling agent..
Package and Storage:
Packing in 25kg pp bag, 27 MT/20`FCL or with customers` requirements. The product shall be sealed and stored in the dry and ventilated place to prevent from rain, high temperature and strong sunlight.
