Sodium sulfate technical GOST 6318 - 77 is received from natural galurgichesky raw materials. Depending on a method of receiving and a scope sodium sulfate technical is let out brands A (the highest, the first and second grades) and B.
And - the product received by industrial methods, the highest and first grades intends for the pulp - and - paper, chemical, glass industry and other purposes.
The B - the product received under natural conditions intends as well as a product of the second grade of brand But only for the glass industry.
Chemical formula: Na2SO4.
Sodium sulfate as one of the main components of furnace charge in production of glass is applied; when processing wood (sulphitic cooking of cellulose), when dyeing cotton fabrics, for receiving viscose silk, various chemical compounds - silicate and sulfide of sodium, sulfate of ammonium, soda, sulfuric acid. It is applied in construction as an antifrosty additive and the accelerator of a skhvatyvaniye of concrete mix. Also sulfate of sodium is applied in production of synthetic detergents; solutions of sulfate of sodium are used as heat accumulator in the devices keeping solar energy.
