Soda ash is also known as sodium carbonate. Soda ash is divided into light soda ash, dense soda ash, and food grade soda ash. Mainly used in the production of glass products, textile printing and dyeing agents, detergents, water treatment, etc.
The appearance is white powder or small crystalline particles, with an astringent taste.
The aqueous solution hydrolyzes to an alkaline state and has a certain degree of corrosiveness. It can neutralize with acids, generate corresponding salts, and release carbon dioxide. It can decompose at high temperatures, generating sodium oxide and carbon dioxide. It will deliquescence in humid air, slowly absorb carbon dioxide and water, and some will become sodium bicarbonate. Therefore, packaging should be strict, otherwise it will absorb water and clump
1. The glass industry is the largest consumer of soda ash, consuming 0.2t of soda ash per ton of glass. It is mainly used for float glass, cathode ray tube glass shell, optical glass, etc.
2. Used in chemical industry, metallurgy, etc. The use of heavy soda ash can reduce the flying of alkali dust, reduce raw material consumption, improve working conditions, and improve product quality. At the same time, it can reduce the erosion of alkali powder on refractory materials and extend the service life of kilns.
3. As a buffer, neutralizer and dough improver, it can be used in pastries and flour-based foods, and should be used in appropriate amounts according to production needs.
4. As a detergent for wool rinsing, bath salts and medicine, and an alkali agent in tanning.
5. Used in the food industry as a neutralizer and leavening agent, such as in the manufacture of amino acids, soy sauce and flour-based foods such as steamed buns and bread. It can also be made into alkaline water and added to flour to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate, etc.
