Usage
1, chemical industry for the production of hydroxyvanillin, hydroxyamine hydrochloride and so on.
2, used as chromatographic analysis reagent.
3, the photographic industry is used as a fixing agent ingredient.
4, the spice industry for the production of vanillin.
5, paper industry used as bleach.
6, rubber industry used as a coagulant.
7, printing and dyeing industry used as a dechlorination agent after cotton bleaching, cotton cooking agent.
8, leather industry for leather processing, can make the leather soft, full, tough, with waterproof, anti-folding, wear and other properties.
9, used in cosmetics, skin care products as anti-fat oxidizer and preservative, prevent and delay the deterioration of products caused by oxidation reaction.
10, used as a reducing agent in water treatment. The use of sodium metabisulfite and sodium sulfide for electroplating wastewater treatment, such as: treatment of wastewater containing hexavalent chromium, you can first add sodium metabisulfite, through the full reduction reaction, adjust the alkali to add polyaluminum chloride or polyiron sulfate flocculant, and finally add sodium sulfide to remove the unfinished precipitation of heavy metals.
11, mine beneficiation agent. Sodium pyrosulfite is an agent that reduces the floatability of minerals. It can form a hydrophilic film on the surface of the ore particles and form a colloidal adsorption film, thus preventing the collector from interacting with the mineral surface.
12, the construction industry is used to manufacture concrete water-reducing agent, which has an early and strong effect in concrete, but the content can not exceed 0.1%-0.3%. If the amount of addition is too large, the later strength of the concrete will be affected.
13, used in the food industry as a preservative, bleach, leavening agent, antioxidant, preservative and color protection agent.
①. Antiseptic fungicide. Adding fruit juice, preserves and cans can extend the shelf life of food and effectively sterilize it.
②. Bleach. Bleach the flour used to make food such as pastries.
③. Leavening agent. It can make the structure of bread and biscuits become loose, and the taste is crunchy.
④. Antioxidant preservatives. It has good antioxidant and fresh-keeping effect on seafood and fruits and vegetables.
⑤. Color protectant. In the process of processing and preservation of light-colored vegetables, such as mushrooms, lotus root, horseshoe, bamboo shoots, yams and other products use sodium metabisulfite solution for color protection.
14, as a feed additive is used as a preservative and anti-mold agent.
15. Pharmaceutical industry
①. For the production of chloroform, phenylpropanone and benzaldehyde.
2. Sodium metabisulfite is added to the injection preparation as an antioxidant. Sodium pyrosulfite has a high solubility in water and is acidic in aqueous solution, which is mainly used as an antioxidant for acidic drugs.
(3) Because it is a reducing agent itself, when it exists at the same time as the drug, sodium metabisulfite is first oxidized after being met with oxygen, which protects the easily oxidized drug ingredients, so as to ensure the stability of the drug preparation.
16, used in the production of insurance powder, sulfadimethylpyrimidine, anergine, caprolactam and so on
