Applications of sodium carbonate in different industries
Applications of sodium carbonate in different industries
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 and other fields. It is used as raw material, cleaning agent and detergent for manufacturing other chemicals. , also used in the fields of photography and analysis. Followed by metallurgy, textiles, petroleum, national defense, and other industries.
The glass industry is the largest consumer sector of soda ash, consuming 0.2 tons of soda ash per ton of glass. Among industrial soda ash, it is mainly used in light industry, building materials, and chemical industry, accounting for about 2/3, followed by metallurgy, textiles, petroleum, national defense, and other industries.
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, picture tube glass shell, optical glass, etc.
2. Used in chemical industry and metallurgy to reduce flying alkali dust, reduce raw material consumption, improve working conditions, improve product quality, reduce the erosion of alkali powder on refractory materials, and extend the service life of the kiln.
3. Used as a detergent for wool rinsing, bath salts and medicinal purposes, and an alkali agent in tanning.
4. Used in the food industry as a neutralizer and leavening agent, such as in the production of amino acids, soy sauce and flour-based foods such as steamed buns, bread, etc. It can also be mixed into alkaline water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce MSG
5. Used in the pharmaceutical industry as antacids and osmotic laxatives.
6. Used for chemical and electrochemical oil removal, electroless copper plating, etching of aluminum, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, anti-rust between processes, electrolytic removal of chromium plating and It can also be used to remove chromium oxide film, etc., in electrolyte for pre-copper plating, steel plating, and steel alloy plating.
7. In the metallurgical industry, it is used as a flux in smelting, a flotation agent for mineral processing, and as a desulfurizer in steel and antimony refining.
8. Used as water softener in printing and dyeing industry.
9. In tanning industry, it is used for degreasing raw hides, neutralizing chrome tanned leather and increasing the alkalinity of chrome tanning liquid.
10. The benchmark for calibrating acid solutions in quantitative analysis. Determination of aluminum, sulfur, copper, lead and zinc. Test urine and whole blood for glucose. Analysis of silica cosolvents in cement. Metallographic analysis of metals, etc.
