Property:

White powder or fine grain. Soluble in water, aqueous solution is strongly alkaline. Slightly soluble in anhydrous ethanol, insoluble in acetone.

Usage:

1, the glass industry is the largest source of soda ash consumption, per ton of glass consumption of soda ash 0.2t. Mainly used for float glass, picture tube glass, optical glass and so on.

2, used in chemical industry, metallurgy, etc. The use of heavy soda ash can reduce the flying of alkali dust, reduce raw material consumption, improve working conditions, but also improve product quality, while reducing the erosion of alkali powder on refractory materials, extend the service life of the kiln.

3, as buffer, neutralizer and dough improver, can be used in pastry and noodle food, according to the production needs of appropriate use.

4, as a detergent for wool rinsing, bath salts and medicine, tanning alkali agent in leather.

5, used in the food industry, as a neutralizer, leavening agent, such as the manufacture of amino acids, soy sauce and pasta food such as steamed bread, bread, etc. It can also be mixed into alkali water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce MSG.

6, color TV special reagent.

7, used in pharmaceutical industry, as an acid antidote, osmotic laxative.

8, used for chemical and electrochemical oil removal, chemical copper plating, corrosion of aluminum, electrolytic polishing of aluminum and alloy, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, electrolytic removal of chromium coating and removal of chromium oxide film, etc., also used in pre-plating copper, steel plating, steel alloy plating electrolyte.

9, metallurgical industry used as smelting flux, flotation agent for beneficiation, steelmaking and antimony smelting used as desulfurizer.

10, printing and dyeing industry used as water softening agent.

11, the leather industry is used for degreasing raw skin, neutralizing chromium tanning leather and improving the alkalinity of chromium tanning liquid.
