use
In production and life, sodium carbonate is used to make pastry, etc., or as a recipe for a variety of detergents. Water purification uses it as a softener. In the industrial soda ash, mainly light industry, building materials, chemical industry, accounting for about 2/3; It is followed by metallurgy, textiles, 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. Chemical industry is used to make Chemicalbook water glass, sodium bichromate, baking soda, borax, trisodium phosphate and so on. Metallurgical industry is used as smelting flux, flotation agent for beneficiation, steel and antimony smelting as desulfurization agent. Printing and dyeing industry used as water softener. The tannery industry is used for degreasing raw skin, neutralizing chrome tanning leather and improving the alkalinity of chrome tanning liquor. It is also used to produce synthetic detergent additives sodium tripolyphosphate and other sodium phosphate salts. Edible grade soda ash is used in the production of MSG, pasta, etc
