Sodium sulfateSodium sulfate is a salt formed by the combination of sulfate and sodium ions. Sodium sulfate is soluble in water and its aqueous solution is neutral. It is soluble in glycerol but not in ethanol. Inorganic compounds, high-purity, fine-grained anhydrous substances are called Yuanming powder. Yuanming powder, white, odorless, bitter crystal or powder, hygroscopic. The appearance is colorless, transparent, large crystals or small granular crystals.
The Characteristics of Sodium SulfateSodium sulfate easily absorbs water when exposed to air, and generates sodium decahydrate, also known as thenardite. Mainly used in the manufacture of water glass, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, feed, etc. At 241 ° C, sodium sulfate will transform into hexagonal crystals. Sodium sulfate is one of the most commonly used post-treatment desiccants in organic synthesis laboratories. The upstream raw materials include sulfuric acid, caustic soda, etc.
1. The chemical industry is used to manufacture sodium sulfide sodium silicate water glass and other chemical products.
2. The cooking agent used in the paper industry to make sulfate pulp.
3. The glass industry is used instead of soda ash as a co-solvent.
4. The textile industry is used to deploy Vinylon spinning coagulant.
5. Used in non-ferrous metallurgy, leather and other aspects.
6. Used to make sodium sulfide, pulp, glass, water glass, enamel, also used as a laxative and antidote for barium salt poisoning. 7. Mainly used as a filler for synthetic detergents.
8. Make the hydration product calcium sulphoaluminate more quickly, thereby speeding up the hydration and hardening of cement.
9. Used as analytical reagents. It is also used in the pharmaceutical industry.
10. Used in chemical, paper and glass, dyes, printing and dyeing, and pharmaceutical industries. It is also used in the manufacture of synthetic fibers, tanning, non-ferrous metallurgy, enamel, etc., and also used as an additive in detergents and soaps.
11. It can be used as a buffer agent in sulfate zinc plating to stabilize the pH value of the plating solution.
