Sodium carbonate (Na2CO3), molecular weight 105.99, also known as pure alkali. Sodium bicarbonate is a white odorless powder or granule at room temperature. Sodium carbonate is easily soluble in water and glycerol, slightly soluble in anhydrous ethanol and difficult to dissolve in propanol.
USES:
Sodium carbonate is one of important chemical raw material, widely used in light industrial chemical, building materials, chemical industry, food industry, metallurgy, textile, oil, defense, medicine, etc, used for manufacture of other chemicals, detergent, detergent raw materials, also used in photography and analysis field. Next came metallurgy, textiles, oil, defence, medicine and other industries. The glass industry is the largest consumer of pure alkali, consuming 0.2 tons per ton of glass. Among the pure alkali used in industry, it is mainly light industry, building materials, chemical industry, accounting for 2/3, followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
1. The glass industry is a large consumer sector of pure alkali, which consumes 0.2t per ton of glass. Mainly used for float glass, picture tube glass case, optical glass, etc.
2. It can also be used in chemical industry, metallurgy and other departments. The use of heavy pure alkali can reduce alkali dust
It can also improve the quality of products, reduce the consumption of raw materials, improve the working conditions, reduce the erosion effect of alkali powder on refractory materials, and extend the service life of kiln.
3. As a buffer, neutralizer and dough improver, it can be used for pastry and flour food, and it can be used appropriately according to production needs.
4. Used as detergent for wool rinsing, bath salt and medicine, and alkali in tannage.
5. Used in the food industry as neutralizer and leavening agent, such as making amino acids, soy sauce and noodles such as steamed bread and bread. It can also be mixed with alkaline water to add to pasta, increasing flexibility and malleability. Sodium carbonate can also be used to make monosodium glutamate
6. Special reagent for color TV sets
7. It is used in the pharmaceutical industry as a deacidizing agent and a permeable laxative.
8, anhydrous sodium carbonate is used in chemical and electrochemical erosion of degreasing, electroless plating copper, aluminum, aluminum and alloy aluminum electrolytic polishing, chemical oxidation, closed, after the phosphating process between remission remission rust and electrolytic chromium plating and chromium oxide film and so on, also used in pre copper plating, plating steel, steel alloy plating in the electrolyte
9. Metallurgical industry is used as smelting flux, flotation agent for ore dressing, steel making and antimony smelting desulfurizer.
10. The printing and dyeing industry is used as a soft water agent.
11. The leather industry is used for degreasing of raw materials, neutralizing chrome tannins and improving the basicity of chrome tanning solution.
12. The benchmark for calibration of acid solution in quantitative analysis. Determination of aluminum, sulfur, copper, lead and zinc. Urine and total blood glucose were examined. Analyze the assistant solvent of silica in cement. Metallographic analysis, etc
Attentions:
Closed operation to enhance ventilation. Operators must be specially trained and strictly follow the operating procedures. It is recommended that operators wear self-inhalation and filtration respirators, wear chemical safety protective glasses, wear anti-toxic infiltration work clothes, and wear rubber gloves. Avoid producing dust. Avoid contact with acids. Light loading and light unloading should be carried to prevent damage to the packaging and container. Equipped with leakage emergency treatment equipment. Empty containers can leave harmful residue. When diluting or preparing a solution, add the base to the water to avoid boiling and splashing.
Storage:
Store in a cool, ventilated warehouse. Keep away from fire and heat. Should be stored separately from acid, avoid mixed storage. The storage area shall be provided with suitable materials for containment of leakage
