99%Min Sodium Carbonate Soda Ash Light Used In Detergent Glassmaking

99%Min Sodium Carbonate Soda Ash Light Washing Chemical Formula

 Soda Ash is composed of sodium carbonate, the molecular formula is Na2CO3, and the molecular weight is 105.99.

Sodium carbonate is a white odorless powder or particle at room temperature, with water absorption, exposed to the air to gradually absorb water, will form caking. There are three kinds of sodium carbonate hydrate containing crystal water, namely sodium monohydrate (Na2CO3·H2O), sodium heptahydrate (Na2CO3·7H2O) and sodium decahydrate (Na2CO3·10H2O). Sodium carbonate is easily soluble in water and glycerol, slightly soluble in absolute ethanol, insoluble in propanol. At 20℃, 20 grams of sodium carbonate can be dissolved per 100 grams of water, and at 35.4℃, the solubility is the maximum, 49.7 grams of sodium carbonate can be dissolved per 100 grams of water.

Soda is an important basic chemical raw material and one of the two bases in the "three acids and two bases", with the reputation of "the mother of chemical industry", widely used in building materials, chemical industry, metallurgy, textile, food, national defense, medicine and many other fields of national economy, occupies a very important position in the national economy.

In the field of building materials, soda, as one of the main raw materials of flat glass, provides sodium ions for the reaction, and is also the main component of the clarifying agent; In the chemical industry, soda ash is widely used in the manufacture of sodium silicate (commonly known as soda, sodium bicarbonate), sodium fluoride, dichromate and other products;

In the field of metallurgy, soda can be used as a co-solvent for smelting, flotation agent for beneficiation and desulfurization agent for steelmaking. In the textile field, soda can be used as a water softener in the process of textile production;

In the field of food processing, soda can be used as a pasta additive to play the role of neutralizer, leavening agent, buffer agent, dough amendment, increase the taste and flexibility of pasta, and can also be used as an auxiliary additive in the production of monosodium glutamate and soy sauce.

In addition, soda is also widely used in environmental desulfurization, pharmaceutical products, tanning, paper making, etc. High-end soda can also be used in picture tube glass shell and optical glass manufacturing.

The combined alkali process is improved and developed on the basis of ammonia alkali process, which was founded by Dr. Hou Debang, the "pioneer of modern chemical industry" in China, in 1938. The upstream of the combined alkali process is mainly raw salt and synthetic ammonia. Through the combined cycle production of "one salt addition, two ammonia absorption and one carbonation" with the ammonia plant, the NH3 and CO2 of the ammonia plant are used to produce soda ash and ammonium chloride simultaneously. Combined alkali method overcomes the shortcomings of ammonia alkali method, the utilization rate of raw salt is greatly improved, without limestone and coke (coal), saving fuel, raw material, energy and transportation costs, while avoiding the discharge of a large number of waste residue and waste liquid, its by-product ammonium chloride can also be used for nitrogen chemical fertilizer, battery manufacturing, electroplating and printing and dyeing.
