Matters needing attention in the operation of sodium bisulfite

Sodium bisulfite has strong reducing properties, so it should not be contacted with acids or acidic substances. The following are the matters needing attention when operating sodium bisulfite.

       Sodium bisulfite should be stored in a cool, ventilated warehouse. Keep away from fire and heat. Prevent direct sunlight. Packaging sealed. It should be stored separately from oxidants, acids and alkalis, and avoid mixed storage. It should not be stored for a long time to avoid deterioration. The storage area should be equipped with suitable materials to contain the leakage.

       Sodium bisulfite harmful combustion products: sulfur oxide, sodium oxide.

       Fire fighting methods: Firefighters must wear acid-alkali-resistant fire fighting suits throughout the body. When extinguishing the fire, move the container from the fire site to an open place as much as possible. Then select the appropriate extinguishing agent to extinguish the fire according to the cause of the fire.

       Precautions for operation of sodium bisulfite: airtight operation, local exhaust. Prevent dust from being released into the workshop air. Operators must undergo special training and strictly abide by the operating regulations. It is recommended that operators wear self-priming filter dust masks, chemical safety protective glasses, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Avoid generating dust. Avoid contact with oxidants, acids and alkalis. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.

       What are the main uses of sodium bisulfite

       The printing and dyeing industry is used as a deoxidizing agent and bleaching agent for various cotton fabrics. It can prevent the localization of cotton fabric fibers and affect the fiber strength, and improve the whiteness of the cooked products. Used as a developer in the photosensitive industry. Used as a reducing agent in the production of m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone-1-sulfonic acid, 1-aminoanthraquinone, sodium aminosalicylate, etc. in the organic industry to prevent semi-finished products in the reaction process Oxidation. Used as lignin removal agent in paper industry. The textile industry is used as a stabilizer for man-made fibers. The electronics industry is used to manufacture photoresistors. The water treatment industry is used for the treatment of electroplating wastewater and drinking water.
