Sodium carbonate is a weak acid, soluble in water after the hydrolysis, so that significant alkaline solution, there is a certain degree of corrosion, with the acid in reaction and generate a corresponding release of carbon dioxide and salt.
Application:
Use the system for chemicals, cleaners, detergents, photography system and pharmaceuticals industries.
In the chemical industry system for water glass, sodium dichromate, sodium nitrate, sodium fluoride, baking soda, borax, trisodium phosphate, and so on. In the metallurgical industry as a metallurgical flux, with ore dressing flotation agent, steel smelting and antimony used as a desulfurization agent.
In printing and dyeing industry as a soft water. Raw materials for leather industry skim the skin, and chrome tanning and improve the degree of chrome tanning liquid. Also used in the production of synthetic detergent additive sodium tripolyphosphate sodium and other salts, and so on.
