What Is Sodium sulfate

Sodium sulfate is an important chemical raw material. It is the main raw material for the production of chemical products such as sodium sulfide and sodium silicate. It can also be used as a filler for synthetic detergents. It is used as a cooking agent in the manufacture of kraft pulp in the paper industry. Sodium sulfate is also known as sodium sulfate, anhydrous mirabilite and anhydrous tannate. White monoclinic fine crystals or powders.

Application of Sodium sulfate

1)Sodium sulfate is an important raw material for making glass and paper. It is used most in papermaking and cellulose industry.

2)Sodium sulfate is a component of synthetic detergent. Adding it can reduce the surface tension and increase the solubility of detergent. It is also a diluent of dyes, an auxiliary for dyeing, printing and dyeing, a dye promoter for direct dyes, sulfur dyes, vat dyes and other cotton fibers, and a dye retarder for silk dyeing with direct dyes.

3)In the chemical industry, sodium sulfate is used as the raw material for manufacturing sodium sulfide, gypsum, sodium silicate and other chemical products.

4)Sodium sulfate cryogen is commonly used in the laboratory. In medicine, mirabilite is used as a laxative. Sodium sulfate is an antidote to barium and lead poisoning..
