Sodium sulfate, also known as sodium sulfate anhydrous, is a fine crystal or powder. Sodium sulfate is an important raw material for the manufacture of glass and paper. It is largely used in the papermaking and cellulose industries
Sodium sulfate is a component of synthetic detergents. It is a neutral salt. Adding it can reduce the surface tension and increase the solubility of detergents. It is also used as a diluent for dyes and an auxiliary for dyeing and printing, as an accelerator for dyeing cotton fibers with direct dyes, sulfur dyes, and vat dyes, and as a retarding agent for direct dyeing of silk.

APPLICATION
Sodium sulfate is an important raw material for the manufacture of glass and paper. It is largely used in the papermaking and cellulose industries, about 70% of the total.
It can also be used in battery, optical glass, printing and dyeing, synthetic detergent, vinylon, fuel, ordinary glass, paper industry, fiber production and inorganic salt and other industrial raw materials.
PACKAGE
50KG or 1000KG bag, plastic bag inside and woven bag outside.
STORAGE
Stored in a cool, ventilated warehouse, away from fire and heat, acids, etcs.
It should be kept separately, avoid mixed reserve.
