The uses of SODIUM SULPHATE ANHYDROUS

The uses of SODIUM SULPHATE ANHYDROUS 99% include many aspects

① It  can be used as a dye filler to adjust it to the standard concentration when producing 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 the dyes in water, enhance the dye uptake, and deepen the color of the finished product.

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

④ SODIUM SULPHATE ANHYDROUS 99%powder is used as a cooking agent in paper making and pulp manufacturing, as a substitute for soda ash as a flux in glass production, as a coagulant for blending vinylon spinning in textiles, as well as synthetic fibers, enamels, leather, etc.

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

⑥ Sodium sulfate is a commonly used post-treatment desiccant in organic synthesis laboratories.
