1. Sodium carbonate is commonly known as soda, soda ash and washing soda.
2. Sodium carbonate (Na2CO3), molecular weight 105.99. The purity of chemicals is more than 99.5% (mass fraction), which is also called soda ash, but it is classified as salt rather than alkali. Also known as soda or soda ash in international trade. It is an important organic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glazes. It is also widely used in domestic washing, acid neutralization and food processing.
3. Use: Sodium carbonate is one of the important chemical raw materials, which is widely used in light industry, daily chemical industry, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine and other fields. It is used as the raw material, cleaning agent, detergent for manufacturing other chemicals, as well as in photography and analysis fields. Next are 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. Among industrial soda ash, light industry, building materials and chemical industry account for about 2/3, followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
4. Hazard: The product has weak irritation and corrosion. Direct contact may cause skin and eye burns. Inhalation of its dust and smoke during production can cause respiratory tract irritation and conjunctivitis, as well as nasal mucosa ulcer, atrophy and nasal septum perforation. Long time contact with the product solution may cause eczema, dermatitis, corny ulcer and skin relaxation. The incidence of respiratory diseases among workers exposed to the product increased. Misuse can cause gastrointestinal burns, mucosal erosion, bleeding and shock.
