SODA ASH

Sodium carbonate is white odorless powder or granules at room temperature. With water absorption, 1mol / L moisture (approximately = 15%) is gradually absorbed in the exposed air. Sodium carbonate is easily soluble in water and glycerin. Every 20 grams of water can dissolve 20 grams of sodium carbonate at 20 ℃, and the solubility is maximum at 35.4 ℃. 49.7 grams of sodium carbonate can be dissolved in 100 grams of water, slightly soluble in absolute ethanol, and hardly soluble in propanol. The solution is alkaline and can make phenolphthalein red.

Sodium carbonate is one of the important chemical raw materials. It is widely used in light industry, daily Chemical Industry, building materials, Chemical Industry, food industry, metallurgy, textile, petroleum, national defense, medicine, etc. Detergents are also used in the fields of photography and analysis. Followed by metallurgy, textile, petroleum, national defense, medicine and other industries. The glass industry is a large consumption department of Soda Ash, which consumes 0.2 tons of soda ash per ton of glass. In the soda ash for industrial use, 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.

Closed operation, strengthen ventilation. Operators must undergo special training and strictly abide by the operating regulations. It is recommended that operators wear self-priming filter dust masks, chemical Safety protective glasses, anti-poison penetration work clothes, and rubber gloves. Avoid generating dust. Avoid contact with acids. Handle lightly when handling to prevent damage to packaging and containers. Equipped with leakage emergency treatment Equipment. Empty containers may be harmful residues. When diluting or preparing a solution, alkali should be added to water to avoid boiling and splashing.

Storage considerations

Store in a cool, ventilated warehouse. Keep away from fire and heat. It should be stored separately from acids, etc., and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.

[Prohibited Materials] Strong acid, aluminum, fluorine
