mainly used as a filler for synthetic detergent. A cooking agent used in the paper industry to make kraft pulp. Used in the glass industry instead of soda ash. Chemical industry used as raw materials for the manufacture of sodium sulfide, sodium silicate and other chemical products. The textile industry is used to prepare vinylon spinning coagulation bath. Used in the pharmaceutical industry as a laxative. Also used in nonferrous metallurgy, leather and other aspects.
1.so that the hydration product calcium sulfoaluminate faster generation, thus speeding up the hydration hardening of cement. The content of sodium sulfate is generally 0.5% to 2% of the quality of cement, which can improve the early strength of concrete by 50% to 100%, and the 28-day strength is sometimes increased, sometimes reduced, and the increase is about 10%, which varies with the type of cement, curing conditions and its content. It is also used as a filler for synthetic detergent, and is also used in paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry.
2.used as an analytical reagent, such as dehydrating agent, digestion catalyst when fixing nitrogen, interference inhibitor in atomic absorption spectrometry analysis. It is also used in the pharmaceutical industry.
3.used in chemical, paper and glass, dyes, printing and dyeing and pharmaceutical industry, in synthetic fiber, leather, non-ferrous metallurgy, porcelain glaze and other manufacturing applications, but also used in detergents and soap as additives.
4.can be used as a buffer in sulfate galvanizing to stabilize the ph value of the bath.fold
