Types of sodium sulphate
Sodium sulphate, chemical name.
Sodium sulfate is a kind of white fine-grained crystal or powder. It is an inorganic compound. It is white, odorless, bitter, highly hygroscopic and soluble in water. Its aqueous solution is neutral.
As a basic chemical raw material, sodium sulphate is widely used in chemical industry, light industry and food industry. It is widely used in synthetic detergent, printing and dyeing industry, glass manufacturing, papermaking industry, Paohua alkali and so on.
According to different uses, sodium sulphate can be divided into industrial grade sodium sulphate and feed grade sodium sulphate; According to different quality, it can also be divided into normal and by-product sodium sulphate.
Industrial grade sodium sulfate can be used as a filler for dyes. In the production of dyes and some additives, sodium sulphate will be used as a filler to adjust the concentration to the standard.
Industrial grade sodium sulfate can be used as a dye promoter for cotton dyeing. When dyeing cotton with some vat dyes, adding sodium sulphate can reduce the solubility of dyes in water.
Industrial grade sodium sulfate can be used as a retarding agent for acid dyes. When dyeing wool and tapestry with acid dyes, the use of sodium sulfate can slow down the dye uptake and slow down the dyeing.
Feed grade sodium sulfate can be used as feed additive in animal husbandry.
The by-product sodium sulfate is produced in the process of producing other chemical products. It is mainly used as cement grinding aid.
