Sodium Carbonate
Sodium carbonate is one of the important chemical raw materials. It is widely used in light industry, daily chemical industry, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine and other fields. It is also used as raw materials, cleaning agents and detergents for manufacturing other chemicals, as well as photography and analysis. Followed by metallurgy, textile, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, with 0.2 tons of soda ash consumed per ton of glass. In industrial soda ash, light industry, building materials and chemical industry account for about 2/3, followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
1. The glass industry is a major consumer of soda ash, consuming 0.2T of soda ash per ton of glass. It is mainly used for float glass, kinescope glass shell, optical glass, etc.
2. It can also be used in chemical industry, metallurgy and other departments. The use of heavy soda ash can reduce the flying of alkali dust, reduce raw material consumption, improve working conditions, improve product quality, reduce the erosion of alkali powder on refractory materials and prolong the service life of kiln.
3. As a buffer, neutralizer and dough improver, it can be used in pastries and flour foods, and can be used in an appropriate amount according to production needs.
4. As a detergent, it is used in wool rinsing, bath salt, medicine and tanning.
5. It is used in food industry as neutralizer and bulking agent, such as amino acid, soy sauce and flour food, such as steamed bread, bread, etc. It can also be prepared into alkaline water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate.
6. Special reagent for color TV.
7. It is used in pharmaceutical industry as antacid and permeable laxative.
8. Anhydrous sodium carbonate is used for chemical and electrochemical oil removal, electroless copper plating, aluminum etching, electrolytic polishing of aluminum and alloy, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, electrolytic chromium removal coating and chromium removal oxide film. It is also used in electrolyte of pre copper plating, steel plating and steel alloy plating.
Metallurgical industry is used as smelting flux and flotation agent for beneficiation, and steelmaking and antimony smelting are used as desulfurizer.
9. It is used as soft water agent in printing and dyeing industry.
10. Leather industry is used for degreasing raw leather, neutralizing chrome tanned leather and improving the alkalinity of chrome tanning solution.
11. Quantitative analysis is the benchmark for determining acid solution. Determination of aluminum, sulfur, copper, lead and zinc. Test urine and whole blood glucose. Analyze the cosolvent of silica in cement. Metal metallographic analysis, etc.
In production and life, sodium carbonate is used to make pastry, sodium hydroxide, etc., or as a formula for a variety of detergents. Water purification uses it as softener. In the industrial soda ash, mainly light industry, building materials, chemical industry, accounting for about 2 / 3; The second is metallurgy, textile, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, consuming 0.2 tons of soda ash per ton of glass. The chemical industry is used to make sodium silicate, sodium dichromate, sodium nitrate, sodium fluoride, sodium bicarbonate, borax, trisodium phosphate, etc. In metallurgical industry, it is used as smelting flux, flotation agent for mineral processing, and desulfurizer for steelmaking and antimony smelting. It is used as a softener in printing and dyeing industry. Leather industry is used for degreasing raw leather, neutralizing chrome tanning leather and improving the alkalinity of chrome tanning liquor. It is also used in the production of synthetic detergent additive sodium tripolyphosphate and other sodium phosphate salts.
