Product Introduction:
Sodium carbonate (Na2CO3), molecular weight 105.99. The purity of chemicals is mostly above 99.5% (mass fraction), also known as soda ash, but it is classified as salt and not alkali. Also known as soda ash or alkali ash in international trade. It is an important inorganic chemical raw material, mainly used in the production of flat glass, glass products, and ceramic glazes. It is also widely used in daily washing, acid neutralization, and food processing.

Product Usage:
Sodium carbonate is one of the important chemical raw materials, widely used in light industry, building materials, chemical industry, food industry, metallurgy, textiles, petroleum, national defense, medicine and other fields. It is used as a raw material for manufacturing other chemicals, cleaning agents, detergents, and also in the fields of photography and analysis. Next are metallurgy, textiles, petroleum, national defense, pharmaceuticals, 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. In industrial soda ash, the main industries are light industry, building materials, and chemical industry, accounting for about 2/3, followed by metallurgy, textiles, petroleum, national defense, pharmaceuticals, and other industries.
1. The glass industry is the largest consumer source of soda ash, consuming 0.2 tons of soda ash per ton of glass. Mainly used for float glass, cathode ray tube glass shells, optical glass, etc.
2. Used in chemical, metallurgical, and other industries. The use of heavy soda ash can reduce alkali dust flying, reduce raw material consumption, improve working conditions, and also improve product quality. At the same time, it can reduce the erosion effect of alkali powder on refractory materials and extend the service life of kilns.
3. As a buffering agent, neutralizing agent, and dough improver, it can be used for pastries and noodle products, and used in appropriate amounts according to production needs.
4. As a detergent used for wool washing, bath salts and pharmaceuticals, and as an alkaline agent in tanning.
5. It is used in food industry as neutralizer and leavening agent, such as manufacturing amino acid, soy sauce and flour food such as Mantou and bread. It can also be mixed with alkaline water and added to noodles to increase elasticity and extensibility. Sodium carbonate can also be used to produce monosodium glutamate.
6. Color TV special reagent.
7. Used in the pharmaceutical industry as an antacid and penetrating laxative.
8. Used for 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 removal of chromium coatings and chromium oxide films, etc. It is also used in electrolytic solutions for pre copper plating, steel plating, and steel alloy plating.
9. The metallurgical industry uses it as a smelting flux, flotation agent for mineral processing, and desulfurizer for steelmaking and antimony smelting.
10. Used as a softening agent in the printing and dyeing industry.
11. The leather industry is used for degreasing raw hides, neutralizing chrome tanned leather, and increasing the alkalinity of chrome tanned liquids.
12. Quantitative analysis serves as the benchmark for determining the acid solution. Determine aluminum, sulfur, copper, lead, and zinc. Test urine and whole blood glucose. Analyze the solubilizer of silica in cement. Metallographic analysis of metals, etc.
