Let's learn something about Sodium Sulfite:

Product properties: Sodium sulfite is a kind of inorganic substance, chemical formula Na2SO3, common sulfite. It can irritate eyes, skin and mucous membranes and pollute water sources. High thermal decomposition produces toxic sulphide smoke. In industry, it is mainly used for making cellulose sulfite ester, sodium thiosulfate, organic chemicals, bleached fabrics, etc., and also used as reducing agent, preservative, dechlorination agent, etc.

Storage: Packing with polythene plastic bags with double kraft paper in the middle or plastic bags. Inner bag binding or heat sealing, outer bag solid seam. Net weight 25kg per bag. Should be stored in a cool, dry warehouse. Packing must be sealed, keep out of contact with air to prevent moisture deterioration. Can not be stored and transported with oxidizer, strong acid and harmful and toxic substances. This product has deliquescence and should not be stored for a long time. Be protected from rain and sun exposure during transportation. In case of fire, water and all kinds of fire extinguishers can be put out.

Usage:

1. Printing and dyeing industry as a deoxidizer and bleaching agent, used for all kinds of cotton fabric cooking, can prevent cotton fiber localization and affect the fiber strength, and improve the whiteness of boiled products.

2. Reductants produced in the organic industry can prevent oxidation of semi-finished products in the reaction process.

3. Paper industry used as lignin remover. Used in the textile industry as a stabilizer for man-made fibres.

4. The electronics industry is used to manufacture photosensitive resistors. The photographic industry uses as a developer.

5. Water treatment industry for electroplating wastewater, drinking water treatment.
