Product name:Anhydrous Sodium Sulfate
Molecular Formular:Na2SO4
Molecular Weight:142.04
Granularity:80-200(Mesh)
Execution Standard:GB/T6009-2003
Property:
White fine particle crystallization or powder,hygroscopic moisture,soluble in water,Aqueous solution is neutral.Soluble in glycerin,insoluble in alcohol.Exposure to gradually absorb 1 molecules of water in the air.High purity, fine particles of substance known as sodium sulfate anhydrous.And the sodium sulfate can form as heptahydrate and decahydrate, heptahydrate is white orthorhombic crystal.When heated to 24.4°C turned anhydrous.Sodium sulfate reaction with carbon at high temperature is reduced to sulfide.
Application:
1.Synthetic detergent used as filling agent.
2.For sodium sulfide,ultramarine blue,sodium silicate and other chemicals’ manufacture.
3.Used for the manufacture of sulfate pulp in papermaking industry.
4.Instead of soda in the glass industry.
5.In dye industry as filler.
6.In printing and dyeing industry is used as dyeing auxiliary.
7.In pharmaceutical industry is used as the delay evacuant and antidote of barium salt poisoning , etc.
8.Used for feed additives.
9.In addition,also has application in the production of synthetic fiber, leather, non-ferrous metallurgy, enamel, soap ,etc.
Production Method:
Obtain sodium sulfate solution through cavern water soluble method ,evaporation dehydrated acquire anhydrous sodium sulfate .
