Usage: Used as materials for synthetic detergent, glass, papermaking, inorganic salts, dyestuff, alcohol fibre, tanning, metal smelting, surface treatment and filler industries etc.
Sodium sulfate Anhydrous is consumed in four major categories; powder detergents as a processing aid and as a filler, wood pulp processing for making kraft paper, textile dyeing processes as a levelling agent to penetrate evenly, and molten glass process to remove small air bubbles. In addition,it is usually used for sodium sulfide , sodium silicate and other chemical products ,synthetic fibers,leather,nonferrous ,metallurgy,enamel and soap etc.
Store and transportation:
Should store at the ventilated , dry storehouse. In summer or high temperature easy to unfreeze and coagulate become big block, should protection against the tide , guard against rain. Pay attention to keep the packing entireness, avoidance get in touch with food , coal, cement etc.. When catch fire, use water and any fire extinguisher to save.
