Applications of ANHYDROUS SODIUM SULPHATE

The use of SODIUM SULPHATE ANHYDROUS 99 percent involves many aspects.

① Can be used as a dye extender to bring it to standard concentration in the production of dyes and some additives.

② When dyeing cotton with direct, sulfurized, reactive, insoluble azo dyes and some vat dyes, sodium sulfate can reduce the solubility of dyes in water, improve dye absorption, and make the color of the finished product deeper.

③ When dyeing wool with acid dyes, sodium sulfate can slow down the absorption of dye and play a good role in delaying dyeing.

④ SODIUM SULPHATE ANHYDROUS 99- percent powder is used as a cooking agent in the production of paper and pulp, as a substitute for soda ash as a flux in glass production, as a coagulant for mixing vinylon spinning in textiles, as well as synthetic fibers, enamels . , leather, etc.

⑤ Sodium sulfate can accelerate the formation of hydration products, accelerate the hydration and hardening rate of cement, and improve early strength.

⑥ Sodium sulfate is a widely used desiccant after processing in organic synthesis laboratories.
