Sodium Carbonate

Sodium carbonate, commonly known as soda, soda ash, soda ash, disodium carbonate, soda ash, is usually a white powder, a strong electrolyte, with a density of 2.532 grams/Cubic centimeters, melting point is 851°Propanol, easily soluble in water and glycerol, slightly soluble in anhydrous ethanol, and insoluble in propanol ，It has the general properties of salt and is an inorganic salt. It absorbs moisture and clumps in humid air, and part of it turns into sodium bicarbonate. The production methods of sodium carbonate include the combined alkali production method 、Ammonia-soda process 、Leblanc process, etc., and can also be processed and refined by natural alkali. As an important inorganic chemical raw material, it is mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in daily washing, acid neutralization and food processing. In terms of the environment, sodium carbonate is generally regarded as a relatively harmless substance to the ecosystem. However, large-scale discharge may still affect the water body.pHvalues ​​and total alkalinity, therefore requiring proper management and supervision during use and handling.

Application Areas

Sodium carbonate is one of the important chemical raw materials, widely used in light industry, daily chemicals, building materials, chemical industry, food industry, metallurgy, textiles, petroleum, national defense, medicine and other fields. It is used as a raw material, cleaning agent, detergent for manufacturing other chemicals, and is also used in photography and analysis. The second largest consumer is metallurgy, textiles, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, with each ton of glass consuming 0.2 tons of soda ash. Among the industrial soda ash, light industry, building materials and chemical industry are the main ones, accounting for about 2/3，Next are metallurgy, textiles, petroleum, national defense, medicine and other industries.

1、The glass industry is the largest consumer of soda ash, with each ton of glass consuming 0.2 tons of soda ash. It is mainly used in float glass, cathode ray tube glass shell, optical glass, etc.

2、Used in chemical industry, metallurgy, etc. Using heavy soda ash can reduce the flying of alkali dust, reduce the consumption of raw materials, improve working conditions, and improve product quality. At the same time, it can reduce the erosion of alkali powder on refractory materials and extend the service life of kilns.

3、As a buffer, neutralizer and dough improver, it can be used in cakes and flour-based foods and should be used in appropriate amounts according to production needs.

4、It is used as a detergent for wool bleaching, bath salts and medicine, and an alkali in leather tanning.

5、Used in the food industry as a neutralizer and leavening agent, such as in the manufacture of amino acids, soy sauce, and flour-based foods such as steamed bread and bread. It can also be made into alkaline water and added to flour-based foods to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate.

6、Color TV special reagents

7、Used in the pharmaceutical industry as an antacid and osmotic laxative.

8、Used for chemical and electrochemical degreasing, chemical copper plating, aluminum etching, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, electrolytic stripping of chromium plating and stripping of chromium oxide film, etc. It is also used in pre-copper plating, steel plating, and iron and steel alloy plating electrolytes.

9、In the metallurgical industry, it is used as a smelting flux, a flotation agent for ore dressing, and a desulfurizer in steelmaking and antimony smelting.

10、Used as a water softener in the printing and dyeing industry.

11、In the leather industry, it is used for degreasing raw hides, neutralizing chrome tanned leather and increasing the alkalinity of chrome tanning liquid.

12、Benchmark for calibrating acid in quantitative analysis. Determination of aluminum, sulfur, copper, lead and zinc. Testing of urine and whole blood glucose. Analysis of silicon dioxide solvent in cement. Metallographic analysis, etc.
