Commodity description:
Chemical name: sodium carbonate
Molecular Formula: Na2CO3
Appearance: white crystalline powder
Properties: soluble in water, alkaline aqueous solution significantly, and release heat, easy to deliquescence; react with the acid salt generated.
Uses: soda is the most important one of chemical raw materials widely used in chemical, glass, metallurgy, paper making, printing and dyeing, synthetic detergent, petrochemical, food, medicine and health industry, the amount of large, important in the national economy status.
Specification: Light Soda Ash (sodium carbonate industry, consumption of soda ash), Dense Soda
The implementation of quality standards:
Industrial soda ash (light soda ash, heavy soda ash) the implementation of People's Republic of China issued the "Industrial sodium carbonate GB210-1992" standards, both product quality reach the international advanced level. Soda consumption of the implementation of People's Republic of China issued a "food additive sodium carbonate GB1886-1992" standard.
Technical indicators for the quality of soda ash consumption: GB1886 - 1992
