Sodium Sulfate Na2SO4 Sodium Sulphate Anhydrous 99% Sateri Viscose Glauber Salt
Sodium sulfate (anhydrous sodium sulfate: Na2SO4) Sodium sulfate sodium sulfate, an inorganic compound, sodium sulfate decahydrate, also known as Glauber's salt, high-purity, fine-grained anhydrous is called sodium sulfate. Yuanming powder, white, odorless, bitter crystal or powder, with hygroscopicity. The appearance is colorless, transparent, large crystals or small granular crystals. Mainly used in the manufacture of water glass, glass, enamel, pulp, refrigerant mixture, detergent, desiccant, dye diluent, analytical chemical reagent, medicine, feed, etc. Appearance and properties: Monoclinic crystal system, short columnar crystals, the aggregates are compact blocks or crust shapes, etc., colorless and transparent, sometimes light yellow or green, and easily soluble in water. White, odorless, bitter crystalline or powder, with hygroscopicity. The appearance is colorless, transparent, large crystals or small granular crystals.

1. Used as a dye filler. When producing dyes and some auxiliaries, make fillers adjusted to standard concentrations. This kind of sodium sulfate has special requirements for the content and fineness of calcium, magnesium, iron, etc., otherwise it will affect the quality of dyes and auxiliaries.
2. As a dye-promoting agent for cotton dyeing. When dyeing cotton with direct, sulfur, reactive, insoluble azo dyes and some vat dyes, adding sodium sulfate can reduce the solubility of the dye in water, thereby increasing the dye uptake rate and deepening the dyed color.
3. Used as a retarder for acid dyes. When dyeing wool and silk with acid dyes, if only sulfuric acid or acetic acid is added, the dyeing speed of the acid dyes will be too fast, and the dyes will not easily penetrate into the fiber, which will cause the color flower. Adding yuanming powder can slow down the dyeing rate. , Play a good slow-dyeing effect.
