Property: white or light yellow crystal powder, a strong smell of sulfur dioxide,relative density is 1.4, easy to dissolve in water and glycerin, water solution. It has acidity,and its solubility will become large while raising the temperature and is less to dissolve in ethanol.
Application:
(1) Food Grade: Bleach agent (e.g. candies, cake, bamboo shoots, etc); Loose agent (e.g. bread, cracker etc); Antiseptic and germicide (e.g. fruit juice, tinned food, brews, the cereals food is defended storage etc); Inhibitor and freshen agent (e.g. day lily, seafood, fruit and vegetable etc).
(2) Industry Grade: Mordant of printing and dyeing; Dechlorinate of textile after bleaching; Sulphonated agent and reducer of chemical industry and pharmacy; Bleach of paper pulp, bamboo and timber bleach of Stap; Treatment agent of waste water; Rubber solidifying agent Perfume industry is served as hydro carbon perfume aldehyde
The hide profession employ to do to molt dose and pliable dose and wearproof dose; sewage treatment, and so on .
(3) Pharmaceutical Grade: In chemical synthesis in the production of acrylic fibre, vitamin K, vitamin A, pharmaceutical intermediates, etc.
(4) Photo Grade: The sensitize industry is served as the developing agent reductant and the protection of fixing bath dose.
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:
Sodium metabisulfite food grade
