I. Basic information:
Anhydrous sodium sulphate is a common name for anhydrous sodium sulfate with a content of 99% or more and a large number of eyes. It is an inorganic sulfate compound, which is commonly known as mirabilite. Anhydrous sodium sulfate is easily soluble in water, and the aqueous solution is weakly alkaline; Appearance is usually white powder or colorless crystal, odorless, slightly bitter, easy to absorb and deliquesce in the air, widely used in glass manufacturing, chemical, textile , paper, metallurgy, medical, chemical analysis, aquaculture and other industries.

Second, classification
First-class products (content 99.2% or more): mainly used in printing and dyeing, glass manufacturing, all kinds of fillers, synthetic detergents, vinylon and so on.

By-product Anhydrous sodium sulphate

One is about 94%, has white agglomerates, but is easy to break, has no chloride ions, and is more suitable as a cement grinding aid.

Third, common packaging:
50 kg woven bag packaging

Fourth, the product uses:
Anhydrous sodium sulphate in chemical applications for the manufacture of sodium sulfide, ultramarine, sodium silicate;

Instead of soda ash as a co-solvent in glass manufacturing;

Used as a filling material for washing industrial synthetic detergents;

The textile industry is used to blend vinylon spinning coagulants;

a cooking agent used in the paper industry for the manufacture of kraft pulp;

Used in non-ferrous metallurgy, leather and other aspects.

It can be used as a buffer in sulphate galvanizing to stabilize the pH of the bath.

The dosage of sodium sulfate is generally 0.5% to 2% of the mass of cement, which can increase the early strength of concrete by 50% to 100%. The strength of 28 days is sometimes increased, sometimes decreased, and the increase is about 10%. With the variety and curing conditions of cement. It varies with its amount. It is also used as a filler for synthetic detergents, and is also used in the paper industry, the glass industry, the chemical industry, the textile industry, and the pharmaceutical industry. 9. Used as an analytical reagent, such as a dehydrating agent, a digestive catalyst for nitrogen determination, and an interference inhibitor in atomic absorption spectrometry. Also used in the pharmaceutical industry
