Sodium carbonate is one of the important chemical raw materials. It is widely used in light industrial daily chemicals, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine, and other fields. It is used as raw materials and cleaning agents for the manufacture of other chemicals. Detergents are also used in photography and analysis. Followed by metallurgy, textiles, petroleum, defense, medicine and other industries. The glass industry is the largest consumer of soda ash and consumes 0.2 tons of soda ash per ton of glass. Among industrial soda ash, mainly light industry, building materials, and chemical industry account for about two-thirds of the total: metallurgy, textiles, petroleum, defense, medicine, and other industries.
The glass industry is a large consumption department for soda ash, and consumes 0.2t of soda ash per ton of glass. Mainly used for float glass, glass tube, optical glass and so on.
It can also be used in chemical, metallurgical and other sectors. The use of heavy soda ash can reduce the emission of alkali dust, reduce the consumption of raw materials, improve working conditions, and improve product quality. At the same time, it can reduce the erosion of alkali powder on refractories and extend the service life of the kiln.
As a buffer, neutralizer and dough improver, can be used for cakes and pasta products, according to production needs in the amount of use.
As a detergent for wool rinsing, bath salts and pharmaceuticals, alkaline agents in tanning leather.
It is used in the food industry as a neutralizing agent and bulking agent, such as amino acids, soy sauce, and pasta products such as steamed bread and bread. Alkaline water can also be added to pasta to increase flexibility and ductility. Sodium carbonate can also be used to produce MSG
TV special reagent
It is used in the pharmaceutical industry as an antacid and osmotic laxative.
Anhydrous sodium carbonate is used for chemical and electrochemical degreasing, electroless copper plating, etching of aluminum, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, rust-proofing between processes, electrolysis to remove chromium Plating and removal of chromium oxide film, also used in pre-plating copper, steel plating, plating steel alloy electrolyte
The metallurgical industry is used as a smelting flux and flotation agent for beneficiation, while steelmaking and refining are used as desulfurizers.
The printing and dyeing industry is used as a water softener.
The tanning industry uses degreased, neutralized chrome tanned leather for raw hides and increases the alkalinity of chrome tannins.
Benchmarking the acid in a quantitative analysis. Determination of aluminum, sulfur, copper, lead and zinc. Test urine and whole blood glucose. Analyze the solubilizer of silica in cement. Metallographic analysis, etc.
