Applications
1. Textile industry: In the textile industry, sodium hydrosulfite is widely used in reduction dyeing, reduction cleaning, printing and decolorization, as well as bleaching of silk, wool, nylon and other fabrics. Because it does not contain heavy metals, the fabrics bleached with insurance powder have bright colors and are not easy to fade. In addition, sodium hydrosulfite can also be used to remove color stains on clothes and update the color of some old gray-yellow clothes.
2. Food industry: In the food industry, sodium hydrosulfite is used as a bleaching agent and can be used for bleaching foods such as gelatin, sucrose, and honey. In addition, it can also be used for bleaching soap, animal (plant) oil, bamboo, porcelain clay, etc.
3. Organic synthesis: In organic synthesis, sodium hydrosulfite is used as a reducing agent or bleaching agent, especially in the production of dyes and medicines. It is a bleaching agent suitable for wood pulp papermaking, has good reducing properties, and is suitable for various fiber fabrics.
4. Papermaking industry: In the papermaking industry, sodium hydrosulfite is used as a bleaching agent to remove impurities in pulp and improve the whiteness of paper.
5. Water treatment and pollution control: In terms of water treatment and pollution control, sodium hydrosulfite can reduce many heavy metal ions such as Pb2+, Bi3+ to metals, which helps reduce heavy metal pollution in water bodies.
6. Preservation of food and fruits: sodium hydrosulfite can also be used to preserve food and fruits to prevent oxidation and deterioration, effectively extending the shelf life of the product.
Although sodium hydrosulfite has a wide range of uses, there are certain dangers in its use. For example, it releases a large amount of heat and toxic gases such as sulfur dioxide and hydrogen sulfide when in contact with water. Therefore, appropriate safety measures need to be taken when using sodium hydrosulfite to prevent accidents.
