Sodium carbonate is one of the important chemical raw materials, widely used in light industrial 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 photography and analysis fields. It is followed by metallurgy, textiles, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, consuming 0.2 tons per ton of glass. In the industrial soda, mainly light industry, building materials, chemical industry, accounting for about 2/3, followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
1. The glass industry is the largest source of soda ash consumption, with 0.2t of soda ash consumed per ton of glass. 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 alkali dust flying, reduce raw material consumption, improve working conditions, but also can improve the quality of products, while reducing alkali powder on refractory erosion action, prolong 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 detergent for wool rinsing, bath salt and medical use, 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 noodle 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 monosodium glutamate
6, color TV special reagent
7, used in pharmaceutical industry, as acid antidote, osmotic laxative.
8, used for chemical and electrochemical oil removal, chemical plating of copper, aluminum etching, aluminum and alloy electrolytic polishing, aluminum chemical oxidation, phosphating after sealing, process rust prevention, electrolytic removal of chromium coating and chromium removal of oxide film, also used for pre-plating copper, plating steel, plating steel alloy electrolyte
9, metallurgical industry used as smelting flux, flotation agent with beneficiation, steel and antimony smelting used as desulfurizer.
10, printing and dyeing industry used as water softener.
11, leather industry is used for degreasing raw skin, neutralizing chrome tanning and improving the alkalinity of chrome tanning liquid.
12. The reference of acid in quantitative analysis. Determination of aluminum, sulfur, copper, lead and zinc. Urine and whole blood glucose were tested. The cosolvent of silica in cement was analyzed. Metallographic analysis, etc.
