Industrial grade sodium metabisulfite manufacturers talk about the storage of sodium metabisulfite and its industrial use

　　Industrial grade sodium metabisulfiteManufacturer: Notes in storage and transportation of sodium metabisulfite

Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, anti-virus infiltration work clothes and rubber gloves to avoid dust, contact with oxidants and acids. Handle with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment, empty containers may leave harmful substances.

Industrial grade sodium metabisulfite manufacturers: storage precautions

Store in a cool, dry and well-ventilated warehouse, away from fire and heat sources, keep the container sealed, and should be stored separately from oxidants, acids and edible chemicals. It should not be mixed and should not be stored for a long time to avoid deterioration. The storage area should be equipped with Suitable materials to control leakage.

　　Industrial grade sodium metabisulfiteManufacturer: What are the industrial uses of sodium metabisulfite?

Sodium metabisulfite is white or yellow crystalline powder or small crystals with a strong SO2 odor. It is soluble in water and the aqueous solution is acidic. When it comes into contact with strong acid, it will release SO2 and generate corresponding salts. If it is placed in the air for a long time, it will be oxidized into Na2S2O6, so this product cannot be used for a long time. The industrial use of sodium metabisulfite is reflected in the following aspects:

1. Used as bleaching agent, mordant, reducing agent, rubber coagulant, also used in organic synthesis, pharmaceutical and spices.

2. Used as chromatographic reagent, preservative and reducing agent, used in dye and pharmaceutical industry.

3, sodium metabisulfite bisulfite sulfate has a more intense reduction, the effect is similar to sodium sulfite. Our country stipulates that it can be used for candied fruit, biscuits, sugar, crystal sugar, maltose, candy, glucose, liquid glucose, bamboo shoots, mushrooms and canned mushrooms, with a large usage of 0.45 g/kg. The residue of candied fruit, bamboo shoots, mushrooms and canned mushrooms, grapes and blackcurrant juice concentrate (calculated as SO2) is less than 0.05 g/kg; The residue of biscuits, sugar, vermicelli and other varieties is less than 0.1 g/kg; The residue of liquid glucose shall not exceed 0.2 g/kg.

4. The food industry is used as a bleaching agent, preservative, filler, antioxidant, color protection agent and preservative.

5. The pharmaceutical industry is used for the production of chloroform, phenylsulfone and benzaldehyde, the rubber industry is used as a coagulant, the printing and dyeing industry is used as a dechlorination agent and a scouring aid after bleaching of cotton cloth, and the tanning industry is used for leather processing, which can make the leather soft, plump, tough, waterproof, bending, wear-resistant and other properties. The chemical industry is used for the production of hydroxyvanillin, hydroxylamine hydrochloride, and photosensitive industry.
