1.Introduction

CAS NO.: 6153-56-6
Molecular Forula: NA2SO4
EINECS NO. 205-634-3
HS CODE:2833190000

Sodium sulfate (NA2SO4) is sulfate and sodium ions generated salt and sodium sulfate soluble in water, its solution for neutral, mostly for alkaline soluble water, soluble in glycerin and not soluble in ethanol.
Inorganic compound, high purity, fine particles of anhydrous substance called yuanming powder.
Yuanming powder, white, odorless, bitter crystals or powder, hygroscopic.
Shape is colorless, transparent, large crystals or granular small crystals.
Sodium sulfate is easy to absorb water when exposed to air, resulting in sodium dechydrate, also known as glauber's salt, which is slightly alkaline.
Mainly used in the manufacture of sodium silicate, glass, porcelain glaze, paper pulp, refrigerant mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, feed and so on.
At 241ºC, sodium sulfate will be converted into hexagonal crystals.
Sodium sulfate is one of the most commonly used post-treatment desiccant in organic synthesis laboratories.
Upstream raw materials include sulfuric acid, caustic soda and so on.

2.Packing:

50kg plastic woven bags or 900kg plastic woven bags

3.Usage:

1, The chemical industry used for the manufacture of sodium sulfide sodium silicate sodium silicate sodium silicate and other chemical products.

2, Paper industry for the manufacture of sulfate pulp cooking agent.

3, The glass industry to replace soda as a solvent.

4. The textile industry is used to prepare vinylon spinning coagulant.

5. Used in non-ferrous metal metallurgy, leather and other aspects.

6, used to produce sodium sulfide, paper pulp, glass, sodium silicate, porcelain glaze, also used as a laxative and barium salt poisoning antidote.
It is a by-product of making hydrochloric acid from table salt and sulfuric acid.
Chemical used in the manufacture of sodium sulfide, sodium silicate, etc.
The laboratory is used to remove barium salts.
Industry used for preparing NaOH and H2SO4 raw materials, also used in paper making, glass, printing and dyeing, synthetic fiber, leather, etc.
Sodium sulfate is one of the most commonly used post-treatment desiccant in organic synthesis laboratories.

7. Mainly used as filling material for synthetic detergent.
A digester used in the paper industry to make kraft pulp.
The glass industry replaces soda ash.
The chemical industry is used as raw material for the manufacture of sodium sulfide, sodium silicate and other chemical products.
The textile industry is used to prepare vinylon spinning coagulation bath.
Used in the pharmaceutical industry as a laxative.
Also used in nonferrous metallurgy, leather and other aspects.

8. Make the hydration product calcium sulphoaluminate form more quickly, thus accelerating the hydration and hardening speed of cement.
The content of sodium sulphate is generally 0.5% ~ 2% of the cement quality, which can increase the early strength of concrete by 50% ~ 100%. The 28-day strength is sometimes increased and sometimes decreased, and the increase rate is about 10%, which varies with the cement varieties, curing conditions and content.
It is also used as filling material for synthetic detergents, paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry, etc.

9. Used as analytical reagents, such as dehydrating agents, digestion catalysts for nitrogen fixation, and interference inhibitors in atomic absorption spectrum analysis.
It is also used in the medical industry.

10.It is used in chemical industry, papermaking and glass, dyestuff, printing and dyeing, medicine industry, and also in the manufacture of synthetic fiber, leather, nonferrous metallurgy, porcelain glaze, etc. It is also used as additive in detergent and soap.

11. It is used as a buffer in sulphate galvanizing to stabilize the pH of the bath.
