Product Description

Product Description

Sodium metabisulfite (Na2S2O5) is an inorganic compound that is a white or yellow crystal with a strong irritating odor. It is soluble in water and the aqueous solution is acidic. When in contact with strong acids, it releases sulfur dioxide and generates corresponding salts. If left in the air for a long time, it will oxidize to sodium sulfate, so sodium metabisulfite cannot be stored for a long time.

Used for producing insurance powder, sulfamethoxazole, acetaminophen, caprolactam, etc; Used for the purification of chloroform, phenylpropylsulfone, and benzaldehyde. Ingredients used as fixing agents in the photography industry; The spice industry is used to produce vanillin; Used as a preservative in the brewing industry; Rubber coagulants and dechlorinating agents for bleached cotton fabrics; Organic intermediates; Used for printing, dyeing, and leather making; Used as a reducing agent; Used for wastewater treatment in the electroplating industry, oil fields, and as mineral processing agents in mines; Used as a preservative, bleach, and loosening agent in food processing.

 Bleaching agent:
1. Textile bleaching: Sodium metabisulfite can remove pigments from textiles, making them pure white and meeting market demand.
2. Paper bleaching: In the papermaking process, sodium metabisulfite can help remove impurities and colors from the paper, making it more high-quality and glossy.
3. Leather bleaching: Sodium metabisulfite can be used for bleaching and cleaning leather products, improving their appearance.
4.Flavor enhancer: It can improve the taste and texture of food, making it more delicious.

 

Used as a reducing agent in water treatment. Sodium metabisulfite and sodium sulfide are used for the treatment of electroplating wastewater. For example, for the treatment of wastewater containing hexavalent chromium, sodium metabisulfite can be added first. After sufficient reduction reaction, polyaluminum chloride or polymeric ferric sulfate flocculants can be added after alkali adjustment, and finally sodium sulfide can be added to remove the unfinished heavy metals.

Application

 Food additives
1. Antioxidant: Sodium metabisulfite can prevent fat oxidation in food and prolong its lifespan.
2. Antimicrobial agent: It can inhibit the growth of microorganisms in food and reduce spoilage.
3. Color retention agent: Sodium metabisulfite can prevent color changes in food, making it look more attractive.
4. Flavor enhancer: It can improve the taste and texture of food, making it more delicious.

 Bleaching agent:
1. Textile bleaching: Sodium metabisulfite can remove pigments from textiles, making them pure white and meeting market demand.
2. Paper bleaching: In the papermaking process, sodium metabisulfite can help remove impurities and colors from the paper, making it more high-quality and glossy.
3. Leather bleaching: Sodium metabisulfite can be used for bleaching and cleaning leather products, improving their appearance.

Also widely used as Mineral processing agents. Sodium metabisulfite is a reagent that reduces mineral floatability. It can form a hydrophilic film on the surface of mineral particles, forming a colloidal adsorption film, thereby hindering the interaction between the collector and the mineral surface
