Product Desciption

Soda ash:
1.shape:odium carbonate is a white odorless powder or particle at room temperature. It has water absorption and gradually absorbs 1mol / L of water (about = 15%) when exposed in the air. The hydrates include Na2CO3 · H2O, Na2CO3 · 7H2O and Na2CO3 · 10h2o.

2.Solubility: sodium carbonate is easily soluble in water and glycerol. At 20 ºC, 20 g of sodium carbonate can be dissolved per 100 g of water, and the solubility is the maximum at 35.4 ºC. 49.7 g of sodium carbonate can be dissolved in 100 g of water, slightly soluble in absolute ethanol and difficult to dissolve in propanol.

3.Chemical properties: the aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent, and can undergo double decomposition reaction with acid, as well as with some calcium salts and barium salts. The solution is alkaline and can turn phenolphthalein red.

4. Soda ash component sodium carbonate, also known as soda soda soda, is an important basic chemical raw material. It is mainly used for building materials, flat glass, daily glass detergent, alumina soda ash. At room temperature, white odorless powder particles have water absorption, exposure and gradually absorb water to form lumps. Sodium carbonate has certain corrosive stability, and can also decompose at high temperature to form sodium oxide and carbon dioxide

5. Soda ash exposed to sodium carbonate for a long time can absorb water and carbon dioxide to produce sodium bicarbonate
According to different density, soda ash is mainly divided into chemical composition for short and physical form of sodium carbonate for short. Different density 500600kgm3 white crystalline powder density 10001200kgm3 white fine particles have the characteristics of solid particle density, moisture absorption, not easy to agglomerate, not easy to fly and fluidity

6. In addition, there are light overweight density of 370 kg m3 and 1550 kg m3 respectively
According to the purpose, soda ash is divided into industrial soda ash and edible soda ash
The 1992 food additive sodium carbonate standard shall be implemented for edible soda ash to realize the basic standard of industrial soda ash, increase the content of heavy metals, and limit the chloride content of soda ash. The chloride content of soda ash is divided into ordinary saline alkali, ultra-low saline alkali and special saline alkali. According to the national standard, the mass fraction of ordinary sodium chloride is 1.20, the mass fraction of ultra-low saline alkali sodium chloride and the mass fraction of special saline alkali sodium chloride.
