Product Description

Sodium sulfate is sulfate and sodium ion synthesis of salt, chemical formula Na2SO4, sodium sulfate soluble in water, its solution is mostly neutral, soluble in glycerol but not soluble in ethanol. Inorganic compounds, high purity, fine particles of anhydrous matter called sodium powder. A white, odorless, bitter crystal or powder with hygroscopic properties. The shape is colorless, transparent, large crystals or small granular crystals. Sodium sulfate is easy to absorb water when exposed to air, resulting in sodium sulfate decahydrate, also known as glauborite, which is alkaline. Mainly used in the manufacture of water glass, glass, porcelain glaze, pulp, refrigerant mixture, detergent, desiccant, dye thinner, analytical chemical reagents, pharmaceuticals, feed and so on. At 241 ° C sodium sulfate transforms into a hexagonal crystal. Sodium sulfate is one of the most commonly used post-treatment desiccant in organic synthesis laboratories. Upstream raw materials include sulfuric acid, caustic soda, etc.
1. Sodium sulfate is 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.
2. The hydration product calcium sulfoaluminate is generated faster, thus speeding up the hydration hardening rate 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%-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.
3. Used as analytical reagents, such as dehydrating agent, digestion catalyst for nitrogen determination, interference inhibitor in atomic absorption spectrometry analysis. It is also used in the pharmaceutical industry.
4. Used in chemical industry, paper making and glass, dyes, printing and dyeing and pharmaceutical industry, in the manufacture of synthetic fibers, leather, non-ferrous metallurgy, porcelain glaze, etc. It is also used as an additive in detergent and soap.
5. It can be used as a buffer in sulfate galvanizing to stabilize the ph value of the plating solution.
