Product introduction

Sodium sulfite is an inorganic substance with the chemical formula of Na₂S₃, a common sulfite. It is irritant to eyes, skin and mucous membrane, and can pollute water sources. Toxic sulfide flue gas is generated by high thermal decomposition. In industry, it is mainly used to produce cellulose sulfite, sodium thiosulfate, organic chemicals, bleached fabrics, etc., and also used as reducing agent, preservative, dechlorination agent, etc.

purpose

1. It is used for the microanalysis and determination of tellurium and niobium, the preparation of developer, and also as a reducing agent.

2. It is used as stabilizing agent for man-made fiber, fabric bleaching agent, photographic developer, dyeing and bleaching deoxidizer, perfume and dye reducing agent, papermaking lignin remover, etc.

3. It is used as common analytical reagent and photoresist material.

4. Reductive bleach has a bleaching effect on food and a strong inhibitory effect on the oxidase in plant foods.

5. As a deoxidizer and bleaching agent, the printing and dyeing industry is used in the cooking of various cotton fabrics, which can prevent the local oxidation of cotton fibers and affect the fiber strength, and improve the whiteness of the cooked fabrics. The photographic industry is used as a developer. The organic industry is used as a reducing agent in the production of m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone - 1 - sulfonic acid, 1-aminoallion quinone, sodium aminosalicylate, etc., which can prevent the oxidation of semi-finished products in the reaction process. Used as lignin remover in paper industry. The textile industry is used as a stabilizer for man-made fibers. The electronic industry is used to manufacture photosensitive resistors. The water treatment industry is used for the treatment of electroplating wastewater and drinking water.

6. Food industry is used as bleach, preservative, loosening agent and antioxidant. It is also used in pharmaceutical synthesis and as a reducing agent in the production of dehydrated vegetables.

7. It is used to prepare cellulose sulfite, sodium thiosulfate, organic chemicals, bleached fabrics, etc., and also used as reducing agent, preservative and dechlorination agent.
