Chinese name: Sodium Carbonate

Foreign name: Sodium Carbonate

Common names: soda, soda ash, washing soda

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

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, textile, petroleum, national defense, medicine and other fields. It is used as raw material, cleaning agent, Detergents are also used in the fields of photography and analysis. Followed by metallurgy, textiles, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, which consumes 0.2 tons of soda ash per ton of glass. In industrial soda ash, mainly light industry, building materials, chemical industry, accounting for about 2/3: followed by metallurgy, textile, petroleum, national defense, medicine and other industries.

The glass industry is a major consumer of soda ash, which consumes 0.2t of soda ash per ton of glass. Mainly used for float glass, kinescope glass bulb, optical glass, etc.

It can also be used in other sectors such as chemical industry and metallurgy. The use of heavy soda ash can reduce soda dust flying, reduce raw material consumption, improve working conditions, and improve product quality. At the same time, it can reduce the corrosion effect of alkali powder on refractory materials and extend the service life of the kiln.

As a buffer, neutralizer and dough improver, it can be used in cakes and pasta foods, and used in appropriate amounts according to production needs.

Used as detergent for wool rinsing, bath salt and medicine, alkali agent in tanning leather.

Used in the food industry as a neutralizer and leavening agent, such as the manufacture of amino acids, soy sauce and pasta foods such as steamed bread and bread. It can also be mixed with alkaline water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce MSG

Color TV special reagents

Used in the pharmaceutical industry as an antacid and osmotic laxative.

Anhydrous sodium carbonate 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, rust prevention between processes, and electrolytic removal of chromium Plating and removing chromium oxide film, etc., also used in pre-plating copper, steel plating, steel alloy plating electrolyte

It is used as smelting flux and flotation agent for ore dressing in metallurgical industry, and as desulfurizing agent for steelmaking and antimony smelting.

Used as water softener in printing and dyeing industry.

The leather industry is used for degreasing raw hides, neutralizing chrome tanned leather and increasing the alkalinity of chrome tanning liquor.

The benchmark for calibrating acid 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. Metallographic analysis, etc.
