1. In the chemical industry, it is used to manufacture sodium sulfide sodium silicate water glass and other chemical products.
2. It is used in the paper industry as a cooking agent for the manufacture of kraft pulp.
3. The glass industry is used to replace soda ash as a co-solvent.
4. The textile industry is used to prepare vinylon spinning coagulant.
5, for non-ferrous metal metallurgy, leather and so on.
6. It is used to make sodium sulfide, pulp, glass, water glass, enamel, and also used as laxative and antidote for barium salt poisoning. Chemically used in the manufacture of sodium sulfide, sodium silicate, etc. Laboratory use to wash away barium salts. In industry, it is used as the raw material for the preparation of NaOH and HSO, and is also used in papermaking, glass, printing and dyeing, synthetic fiber, leather making, etc. Sodium sulfate is one of the most commonly used post-processing desiccants in organic synthesis laboratories.
7. Mainly used as a filler for synthetic detergents. Cooking agent used in the paper industry to make kraft pulp. Glass industry 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. Textile industry is used to prepare vinylon spinning coagulation bath. The pharmaceutical industry is used as a laxative. Also used in non-ferrous metallurgy, leather and so on.
8. The hydration product calcium sulfoaluminate is generated faster, thereby accelerating the hydration and hardening speed of cement. The dosage of sodium sulfate is generally 0.5%~2% of the cement quality, which can improve the early strength of concrete by 50%~100%. The 28-day strength sometimes increases, sometimes decreases, and the increase rate is about 10%. and its dosage varies. It is also used as a filler for synthetic detergents, and is also used in the paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry.
