Sodium carbonate has the chemical formula Na2CO3. It is commonly known as soda, soda ash, alkali ash, disodium carbonate salt, and soda ash. It is usually a white powder and a strong electrolyte. It has a density of 2.532g/cm3 and a melting point of 851°C. It is soluble in water and glycerin, slightly soluble in absolute ethanol, and insoluble in propanol. It has the general properties of a salt and belongs to an inorganic salt.The humid air will absorb moisture and clump, and part of it will become sodium bicarbonate.As an important inorganic chemical raw material, it is mainly used in the production of flat glass, glass products and ceramic glazes.It is also widely used in household washing, acid neutralization, and food processing.In terms of the environment, sodium carbonate is usually regarded as a relatively harmless substance to the ecosystem.

Application Description

Sodium carbonate is one of the important chemical raw materials. It is widely used in light industry, daily chemicals, building materials, chemical industry, food industry, metallurgy, textiles, petroleum, national defense, medicine and other fields. It is used as raw materials, cleaning agents, and detergents for the manufacture of other chemicals. It is also used in the field of photography and analysis.The glass industry is the largest consumer sector of soda ash, consuming 0.2 tons of soda ash per ton of glass.Among the industrial soda ash, it is mainly light industry, building materials, and chemical industry, accounting for about 2/3, followed by metallurgy, textiles, petroleum, national defense, medicine, and other industries.
1. The glass industry is the largest source of soda ash consumption, consuming 0.2t of soda ash per ton of glass.It is mainly used for float glass, picture 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 the consumption of raw materials, improve working conditions, and improve product quality. At the same time, it can reduce the corrosive effect of alkali powder on refractory materials and extend the service life of the kiln.
3. As a buffer, neutralizing agent and dough improver, it can be used in pastries and prepared foods, and it can be used in moderation according to production needs.
4. It is used as a detergent for wool rinsing, bath salt and medicine, and as an alkali agent in tanning leather.
5. It is used in the food industry as a neutralizing agent and leavening agent, such as the manufacture of amino acids, soy sauce and noodle foods such as steamed buns and bread.It can also be formulated into alkaline water and added to pasta to increase elasticity and ductility.Sodium carbonate can also be used in fermentation industries such as the production of monosodium glutamate.
6. It is used in the pharmaceutical industry as an antacid and a permeable laxative.
7. It is used for chemical and electrochemical degreasing, electroless copper plating, aluminum etching, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, anti-rust between processes, electrolytic removal of chromium coating and removal of chromium oxide film, etc., It is also used in electrolytes for copper plating, steel plating, and other iron alloys.
8. It is used as a flux for smelting and flotation agent for mineral processing in the metallurgical industry, and as a desulfurization agent for steelmaking and antimony refining.
9. Used as a water softener in the printing and dyeing industry.
10. The tanning industry is used for degreasing raw leather, neutralizing chrome tanned leather and improving the alkalinity of chrome tanning solution.
11. The benchmark for determining the acid solution in quantitative analysis.Determination of aluminum, sulfur, copper, lead and zinc.Test urine and whole blood glucose.Analyze the co-solvent of silica in cement, metal metallographic analysis, etc.
