Basic information:
Anhydrous sodium sulphate is called anhydrous sodium sulfate as white fine-grained crystal or powder. It is hygroscopic, soluble in water and neutral in aqueous solution. Soluble in glycerin, not soluble in alcohol. The anhydrous substance with high purity and fine particle size is called Anhydrous sodium sulphate. 

The chemical industry is used to manufacture sodium sulfide sodium silicate water glass and other chemical products. 
The cooking agent used in the paper industry for the manufacture of kraft pulp. 
The glass industry to replace soda ash as a cosolvent. 
The textile industry is used to blend vinylon spinning coagulants.
For non-ferrous metallurgy, leather and other aspects. 
Used to make sodium sulfide, pulp, glass, water glass, enamel, also used as a laxative and antidote to strontium salt poisoning. It is a by-product of the production of hydrochloric acid from salt and sulfuric acid. Chemically used in the manufacture of sodium sulfide, sodium silicate, etc. The laboratory is used to wash away the strontium salt. Industrially used as a raw material for the preparation of NaOH and H2SO4, also used in paper, glass, printing and dyeing, synthetic fiber, leather and so on. Sodium sulfate is the most commonly used post-treatment desiccant in organic synthesis laboratories. 
Mainly used as a filler for synthetic detergents. A cooking agent used in the paper industry to make kraft pulp. The glass industry is used to replace soda ash. The chemical industry is used as a raw material for the manufacture of sodium sulfide, sodium silicate and other chemical products. The textile industry is used to blend vinylon spinning coagulation baths. The pharmaceutical industry is used as a laxative. Also used in non-ferrous metallurgy, leather and other aspects.
