Use of sodium sulfate
Sodium sulfate to sodium sulfide production, pulp and paper, glass, water glass, enamel, also used as a laxative and barium salt poisoning antidote. Is a by-product of the production of hydrochloric acid with salt and sulfuric acid. The chemical industry for the manufacture of sodium sulfide, sodium silicate, etc.. Laboratory for the wash out of the barium salt. Industrial used as a raw material for the production of NaOH and SO H, also used in paper, glass, printing and dyeing, synthetic fiber, leather, etc.. In the organic synthesis laboratory sodium sulfate is one of the most commonly used after treatment desiccant.
The use of sodium sulfate
1, the chemical industry used in the manufacture of sodium sulfide, sodium sulfide, sodium silicate (sodium silicate) and other chemical products. Production of sulfur base: the production of 1 tons of sulfur base needs about 1.6 tons of anhydrous sodium sulfate.
2, synthetic detergent: washing synthetic detergent industry. The amount of detergent is generally accounted for about 45% of the total amount of the entire industry accounted for about 45% of total amount of domestic mirabilite.
3, pulp and paper industry for the production of kraft pulp cooking agent.
4, glass: glass industry to substitute for soda, do help solvent. The amount of sodium sulfate in glass industry accounted for the total amount of 12%.
5, textile printing and dyeing textile industry for the deployment of Vigny Lun spinning coagulant.
6, for non-ferrous metals metallurgy, leather and other aspects.
7, special Glauber's salt includes sodium sulfate used in feed, medicine and other fields, and used in the detergent industry in coarse particles, color particles, such as new varieties.
The effect of different grades of sodium sulfate:
Sodium sulfate content among them, aliquots of impurities and color for different grades according to the, now the related knowledge introduction is as follows, to initiate it.
Electronic grade (mainly containing >99.99): mainly used in medicine as an antidiarrheal agent, the amount of small, there is no domestic production, mainly concentrated in Japan.
A class of one grade products (>99.0): mainly used for printing and dyeing, synthetic detergent, Vigny, etc..
