What is the purpose and function of sodium carbonate?

The uses of sodium carbonate are as follows:

1. The glass industry is the largest consumer of soda ash, consuming 0.2t of soda ash per ton of glass. Mainly used in float glass, kinescope glass shell, optical glass, etc.

2. It can also be used in chemical, metallurgical and other departments. The use of heavy soda ash can reduce alkali dust flying, reduce raw material consumption, improve working conditions, improve product quality, reduce the corrosion of alkali powder on refractories and prolong the service life of kiln.

3. As a buffer, neutralizer and dough improver, it can be used for cakes and flour products, and can be used appropriately according to production needs.

4. Used as wool washing agent, bath salt and medicine, and also used as alkaline reagent for tanning.

5. Used as neutralizer and leavening agent in food industry, such as making amino acids, soy sauce, steamed bread, bread and other flour products. It can also be made into alkaline water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate.

Extended data: sodium carbonate [497- 19-8](Na2CO3), molecular weight 105.99. The purity of chemicals is more than 99.5% (mass fraction), which is also called soda ash, but it belongs to salt, not alkali. Also known as soda or soda ash in international trade. It is an important organic chemical raw material, which is mainly used to produce flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization and food processing.
