Main purpose 1. The chemical industry is used to manufacture sodium sulfide, sodium silicate, water glass and other chemical products. 2. A cooking agent used in the manufacture of kraft pulp in the paper industry. 3. Glass industry is used to replace soda ash as cosolvent. 4. The textile industry is used to prepare vinylon spinning coagulant. 5. Used in nonferrous metal metallurgy, leather, etc. 6. It is used to make sodium sulfide, pulp, glass, water glass and porcelain glaze. It is also used as a laxative and an antidote to barium salt poisoning. It is a by-product of produced from salt and sulfuric. In chemical industry, it is used to manufacture sodium sulfide, sodium silicate, etc. The laboratory is used to wash away barium salts. In industry, it is used as raw material for the preparation of and It is also used in papermaking, glass, printing and dyeing, synthetic fiber, leather making, etc. Sodium sulfate is one of the most commonly used post-treatment desiccants in organic synthesis laboratory. 7. It is mainly used as filler for synthetic detergent. A cooking agent used in the manufacture of kraft pulp in the paper industry. Glass industry is used to replace soda ash. The chemical industry is used as raw materials for manufacturing sodium sulfide, sodium silicate and other chemical products. The textile industry is used to prepare vinylon spinning coagulation bath. The pharmaceutical industry is used as a laxative. It is also used in nonferrous metallurgy, leather, etc. 8. The hydration product calcium sulphoaluminate is formed faster, which speeds up the hydration and hardening speed of cement. The content 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 and sometimes decreases, and the increase range is about 10%, which varies with the cement variety, curing conditions and content. It is also used as filler for synthetic detergent, paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry. 9. It is used as analytical reagent, such as dehydrating agent, digestion catalyst in nitrogen determination, and interference inhibitor in atomic absorption spectrometry. It is also used in the pharmaceutical industry. 10. It is used in chemical industry, papermaking, glass, dyestuff, printing and dyeing and pharmaceutical industry. It is also used in the manufacture of synthetic fiber, tanning, non-ferrous metallurgy and enamel. It is also used as an additive in detergent and soap. 11. It can be used as a buffer in sulfate zinc plating to stabilize the pH value of the bath.
