1. The glass industry is the largest consumer of soda ash, with each ton of glass consuming 0.2t of soda ash. It is mainly used in float glass, cathode ray tube glass shell, optical glass, etc.
2. It is used in chemical industry, metallurgy, etc. The use of heavy soda ash can reduce the flying of alkali dust, reduce raw material consumption, improve working conditions, and improve product quality. At the same time, it can reduce the erosion of alkali powder on refractory materials and extend the service life of kilns.
3. It can be used as a buffer, neutralizer and dough improver for pastries and flour-based foods, and should be used in appropriate amounts according to production needs.
4. It can be used as a detergent for wool rinsing, bath salts and medicine.
5. It can be used in the food industry as a neutralizer and leavening agent, such as in the manufacture of amino acids, soy sauce and flour-based foods such as steamed buns and bread. It can also be made into alkaline water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate.
7. It can be used in the pharmaceutical industry as an antacid and osmotic laxative.
8. Used in chemical and electrochemical degreasing, chemical copper plating, aluminum etching, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, electrolytic stripping of chromium plating and stripping of chromium oxide film, etc. It is also used in pre-copper plating, steel plating, and iron and steel alloy plating electrolyte.
9. Used as smelting flux and flotation agent for mineral processing in the metallurgical industry, and as desulfurizer in steelmaking and antimony smelting.
10. Used as a water softener in the printing and dyeing industry.
