Product Applications

Sodium Carbonate is used as analytical reagents, such as reference reagent, dissolving sample flux, precipitant, buffer, and sample volatilizer in emission spectrum analysis. It is also used to prepare sodium salt, pharmaceutical excipients, sodium glass and film printing and washing, optical glass, etc.

Properties

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.
