5 Character: Anhydrous is a white crystalline powder, relative density 2.53, melting point 851 ºC, heated to 400 ºC decomposition. Insoluble in ethanol, soluble in water, dissolved when heat, solution is strongly alkaline. Easily deliquescence agglomeration in the air, absorb CO2 and produce sodium bicarbonate. Monohydrate as a fine white crystal or powder, the relative density of 1.55. Stable at room temperature and heated to lose crystal water becomes anhydrous at 100 ºC. Decahydrate colorless transparent crystallization temperature 34 ºC, relative density (20 ºC) 1.44, in the air easily weathered.

6 Usage: It is one of the important chemical raw materials used in making chemicals, cleaning agents, detergents, but also for photography and manufacturing pharmaceuticals products.

7 Packing: It is packed with polythene bag as the inner layer, and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg.

8 Storage and Transport: It should be stored in a dark, dry and ventilative warehouse, kept away from water and moisture; unloaded with care to avoid damage. Furthermore, it must be stored separately from poisonous substances.

Product Description :
PRODUCT APPLICATION
1. As a buffer, neutralizer and dough improver, it can be used in pastry and pasta, and it can be used in an appropriate amount according to production needs.
2. As a detergent for wool rinsing, bath salts and pharmaceuticals, alkaline agents in tanning.
3. Used in the food industry as a neutralizing agent and a leavening agent, such as amino acid, soy sauce and pasta such as steamed bread and bread. It can also be added to the pasta with alkaline water to increase elasticity and ductility. Sodium carbonate can also be used to produce MSG

1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
2. Soda ash also is used to clean the air and soften water.

3. Manufacture of Caustic Soda and dyestuffs

4. metallurgy (processing of steel and extraction of iron etc),

5. (flat glass, sanitary pottery)

6. national defense (TNT manufacturing, 60% gelatin-type dynamite ) and some other aspects, such as rock oil refining, paper manufacturing, paint, salt refining, softening of hard water, soap, medicine , food and so on.
