Description
Product English name: Sodium Sulphate Anhydrous
Product Alias: Yuanming powder; anhydrous sodium sulfate molecular formula: Na2SO4 molecular weight: 142.04 CAS NO: 7757-82-6
Properties: White fine particles crystal or powder, hygroscopic, easily soluble in water, and the aqueous solution is neutral. Soluble in glycerin, insoluble in alcohol. Exposure to air will gradually absorb 1 molecule of water. Anhydrous substances with high purity and fine particles are called Yuanmingfen. Sodium sulfate can form heptahydrate and decahydrate, heptahydrate (Na2SO4 · 7H2O) is white rhombic crystal. When heated to 24.4 ℃, it turns into anhydrous. Sodium sulfate and carbon are reduced to sodium sulfide when reacting at high temperature.
Uses: Synthetic detergents are used as fillers. Used in the manufacture of chemical products such as sodium sulfide, ultramarine, sodium silicate, used in the manufacture of sulfate pulp in the paper industry, used to replace soda ash in the glass industry, and used as a filler in the dye industry. Used as a dyeing aid in the printing and dyeing industry, and as a laxative in the pharmaceutical industry. In addition, it is also used in the manufacture of synthetic fibers, leather, non-ferrous metallurgy, enamel, soap, etc.
Production method: Dissolve Glauber's salt in the chamber water-soluble method, and produce anhydrous sodium sulfate by evaporation and dehydration.
Packing: 25kg or 50kg plastic woven bag lined with a layer of plastic bag.
