DESCRIPTION

Edible Sodium Carbonate

Molecular formula: Na2CO3

Appearance: white powdery crystal

Properties: easily soluble in water, the aqueous solution is alkaline, and gives off heat, easy to deliquescence; React with acid to form a salt. Usage: soda ash is one of the most important chemical raw materials. It is widely used in the chemical industry, glass, metallurgy, papermaking, printing and dyeing, synthetic detergent, petrochemical industry, food, medicine and health, and other industries. With large consumption, it plays an important role in the national economy.

Specification: Edible Sodium Carbonate

Quality standards for edible Sodium Carbonate:

Edible Sodium Carbonate shall comply with the standard of food additive sodium carbonate GB1886.1-2015 issued by the people's Republic of China.

Typical 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.
