PROFESSIONAL SMBS PRODUCER SINCE 1999, we are the main producer and exporter for sodium metabisulfite, food and tech grade for years , when you have any demands, please feel free to contact with us . 

 

Uses: Photographic developer, Chrome tanning of leather, Manufacture of dyes and chemicals, Dyeing of textiles, Antichlor in bleaching(cotton, Wool, fiber , etc.),Preservative for food, Deal with waste water containing with chrome, Reducing agent for chemical, Handle latex emulsion, Rayon, Paper, medical industries.

 

It is mainly used as reduction agent. Furthermore, sodium metabisulfite is ideal for the bleaching of vegetable fibers and textile, for the production of solutions, which are used in the developing of photos and films as well as for the treatment of tanning agents in dyeing of textiles. ChoiceChem offers different grades’ sodium metabisulfite, all meeting highest quality standards.

 
Nature:

 

white or light yellow crystalline powder , relative density is 1.4 . Soluble in
water (when20 ° C, 54g/100ml water; when 100 ° C, 81.7g/100ml water),
acidic aqueous solution. Soluble in glycerine, slightly soluble in ethanol.
Moisture easily decomposed, exposed in the air easily oxidized into
sulfate. Exposure to emit sulfur dioxide and acid generated the corresponding
salts. Heated to 150 ° C decomposition.
Usage:
Pharmaceutical industry for the production of chloroform, benzene, styrene
sulfone, and formaldehyde. Rubber industry as a coagulant. Bleached cotton
printing and dyeing industry as the dechlorination agent, cotton scouring agent.
Leather tanning industry for processing, make the leather soft, plump, tough,
waterproof, bending, wear and other properties. The chemical industry for the
production of vanillin hydroxyl, hydroxylamine hydrochloride and so on.
Sensitive industries such as reagent. The food industry as a bleaching agent,
preservatives, leavening agent, antioxidant, color agents and the insurance agent.
According to China GB2760-86 provides that: as a preservative for the wine, the
greatest use of 0.25g/kg; as bleaching agent for glucose, sugar, bamboo, rattan
and other mushrooms, no more than 0.45g/kg; residue (SO2 total), bamboo shoots,
mushrooms are not allowed more than 0.025k/kg.
