Applications and usages:
Anhydrous sodium sulfate is an important filler in laundry powders and detergents,
Used as a raw material for sulfate pulping in the production of pulp.
It acts as an additive in the dyeing process to help dyes distribute evenly
Serves as a raw material for the production of sodium sulfide, sodium silicate, and other chemical products.
In glass production, it is used as a clarifying agent to remove bubbles from molten glass.
Should be stored in a dry and well-ventilated warehouse, avoiding humid environments. Storage:The temperature should be kept at room temperature (15-25°C) with a relative humidity below 50%. Keep away from acids and strong oxidizers to prevent chemical reactions.
