Sodium sulfate technical GOST 6318 - 77 is received from natural galurgichesky raw materials. Depending on method of receiving and range of application technical sodium sulfate 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 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 (sulfite digestion of cellulose), when dyeing cottons, for receiving viscose silk, different chemical compounds - silicate and sodium sulfide, ammonium sulfate, soda, sulphuric acid. It is applied in construction as antifrosty additive and the accelerator of skhvatyvaniye of concrete mix. Also sodium sulfate is applied in production of synthetic detergents; solutions of sodium sulfate are used as heat accumulator in the devices keeping solar energy.
