Application and Usage

1. The chemical industry is used to make sodium sodium sulphide sodium silicate water glass and other chemical products.
2. The cooking agent used in the making of kraft pulp in the paper industry.
3. The glass industry is used instead of pure alkali as a cosolvent.

4, the textile industry for the deployment of Vigny Lun spinning coagulant.
5, for non-ferrous metal metallurgy, leather and other aspects.
6, used for sodium sulfide, pulp, glass, water glass, enamel, also used as a laxative and barium salt poisoning antidote. It is a
by-product of the use of salt and sulfuric acid in the manufacture of hydrochloric acid. Chemical is used in the manufacture of
sodium sulfide, sodium silicate and so on. The laboratory is used to wash out barium salts. Industry for the preparation of NaOH and H SO material, also used for paper, glass,  printing and dyeing, synthetic fiber, leather etc.. In Organic Synthesis Laboratory of sodium sulfate is one of the most commonly used desiccant postprocessing.
7. It is mainly used as a filling material for synthetic detergent. A steaming agent used in the manufacture of kraft pulp in the paper industry. The glass industry is used instead of soda. 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 adjust the Vigny spinning coagulation bath. The pharmaceutical industry used as a laxative. It is also used in non-ferrous metallurgy, leather and other aspects.
8. the hydration product of calcium sulphoaluminate is produced faster, and the hydration speed of cement is accelerated. The content of sodium sulfate is generally 0.5% ~ 2% of the cement quality, which can increase the early strength of concrete 50% ~ 100%, and the intensity of 28 days is sometimes increased, sometimes decreasing. The increase range is about 10%, which varies with cement variety, curing condition and dosage. It is also used as a filler for synthetic detergent and also in the paper industry, the glass industry, the chemical industry, the textile industry and the pharmaceutical industry.
9. It is used as an analytical reagent, such as a dehydrating agent, a digestible catalyst for nitrogen determination, and a interference inhibitor in the analysis of atomic absorption spectrometry. It is also used in the pharmaceutical industry.
10, used in chemical industry, papermaking, printing and dyeing, dye and glass and pharmaceutical industry, can also be used in making synthetic fiber, leather, non-ferrous metallurgy, enamel, also used as additives in detergents and soaps.
11. It can be used as a buffer in the sulphate zinc plating to stabilize the pH value of the plating bath.
