Sodium carbonate (Na2CO3), molecular weight 105.99, also known as soda ash. Sodium carbonate is white and odorless powder or particle at room temperature. It is absorbent. Sodium carbonate is soluble in water and glycerin, slightly soluble in anhydrous ethanol, but insoluble in propanol.
To use:
Sodium carbonate is one of the important chemical raw materials, widely used in light industry, daily chemical, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine and other fields, as raw materials for the manufacture of other chemicals, cleaning agents, detergents, also used in the field of photography and analysis. It is followed by metallurgy, textiles, petroleum, national defence, pharmaceuticals and other industries. The glass industry is the largest consumer of soda ash, consuming 0.2 tons per ton of glass. Of the industrial soda ash, it is mainly light industry, building materials industry and chemical industry, accounting for about two-thirds, followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
1.The glass industry is the soda ash consumption department, per ton of glass consumption soda ash 0.2t. Mainly used for float glass, picture tube glass shell, optical glass, etc.
2. It can also be used in chemical industry, metallurgy and other departments. The use of heavy soda can reduce the dust, reduce the consumption of raw materials, improve the working conditions, improve the quality of products, reduce the erosion of alkali powder on refractory materials, and prolong the service life of kilns.
3. As buffer, neutralizer and dough improver, it can be used for pastries and flour food. It can be used appropriately according to production needs.
4. Used as detergent in wool rinsing, bath salt and medicine, alkali in tanning leather.
5. For the food industry, as a neutralizer, leavening agent, such as the manufacture of amino acids, soy sauce and flour food such as steamed bread, bread, etc. It can also be added into pasta as alkali water to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate.
6. Special reagent for color TV
7.Used in the pharmaceutical industry, as an acid antidote, permeability laxative.
8. Anhydrous sodium carbonate is used in chemical and electrochemical oil removal, chemical copper plating, etching of aluminum, electrolytic polishing of aluminum and alloy, chemical oxidation of aluminum, closure after phosphating, anticorrosion between processes, electrolytic chromium-removing coating and chromium-removing oxide film, etc., and is also used in pre-copper plating, steel plating, and steel plating alloy electrolyte
9. In the metallurgical industry, it is used as flux for smelting, flotation agent for ore dressing, and desulfurizer for steelmaking and antimony smelting.
10. Used as a water softener in printing and dyeing industry.
11. The leather industry is used for degreasing, neutralizing chrome tanned leather and improving the basicity of chrome tanning liquid.
12. Standard of acid calibration in quantitative analysis. Determination of aluminium, sulphur, copper, lead and zinc. Test urine and whole blood glucose. The cosolvent of silica in cement was analyzed. Metallographic analysis of metals.
