Product Description

Sodium carbonate (soda)

CAS NO.497-19-8

Sodium carbonate (Na2CO3), the purity of the chemical is more than 98.5% (mass fraction), sodium carbonate (Na2CO3), also known as soda ash. Sodium carbonate is a white odorless powder or granule at room temperature and is water absorbing. Sodium carbonate is easily soluble in water and glycerin, slightly soluble in anhydrous ethanol, and insoluble in propanol. Also known in international trade as soda or soda ash. It is an important organic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in domestic washing, acid neutralization, and food processing.

Molecular formula: Na 2 CO 3

Appearance: white powder crystal

Properties: Soluble in water, alkaline in aqueous solution, and release heat, easy to deliquesce; react with acid to form salt.

use:

Sodium carbonate is one of the important chemical raw materials. It is widely used in the fields of light industry, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine, etc. It is used as raw material and cleaning agent for other chemicals. Detergents are also used in the field of photography and analysis. Followed by metallurgy, textiles, petroleum, national defense, medicine and other industries. The glass industry is soda ash. In the large consumer sector, 0.2 tons of soda ash per ton of glass is consumed. In industrial soda ash, it is mainly light industry, building materials, chemical industry, accounting for about 2/3: followed by metallurgy, textile, petroleum, national defense, medicine and other industries.

•  The glass industry is the large consumption department of soda ash, which consumes 0.2t of soda ash per ton of glass. Mainly used for float glass, tube glass bulbs, optical glass, etc.

•  It can also be used in other departments such as chemical industry and metallurgy. The use of heavy soda ash can reduce the flying of alkali dust, reduce the consumption of raw materials, improve the working conditions, improve the quality of products, reduce the erosive effect of alkali powder on refractory materials, and prolong the service life of kiln.

•  as a buffer, neutralizer and dough improver, can be used in pastry and pasta, according to the needs of production.

Used as a detergent for wool rinsing, bath salts and pharmaceuticals, alkaline agents in tanning.

•  used in the food industry, as a neutralizer, leavening agent, such as the manufacture of amino acids, soy sauce and pasta products such as taro, bread and so on. It can also be added to the pasta with alkaline water to increase elasticity and ductility. Sodium carbonate can also be used to produce MSG

Color TV special reagent

•  used in the pharmaceutical industry, as an antacid, osmotic laxative.

•  Anhydrous sodium carbonate is used for chemical and electrochemical degreasing, electroless copper plating, aluminum etching, electrolytic polishing of aluminum and alloy, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, and electrolysis In addition to chrome plating and chromium-removed oxide film, it is also used in pre-plated copper, plated steel, and plated steel alloy electrolytes.

•  The metallurgical industry is used as a smelting flux, flotation agent for ore dressing, steelmaking and smelting as a desulfurizer.

•  The printing and dyeing industry is used as a softener.

•  The tanning industry is used for degreasing of raw material skin, neutralizing chrome tanning and increasing the alkalinity of chrome tanning liquid.
