1. Industrial Field: a Anti-scaling and anti-corrosion: Sodium hypophosphite can be used to prevent pipeline scaling, especially in hot water pipelines and oil field scale inhibition applications. a Dispersed surface treatment: In the production of concrete admixture polycarboxylic acid, sodium hypophosphite serves as a dispersant, helping to form a stable system, and can serve as a catalyst or stabilizer for chemical reactions. a c Electroless plating reducing agent: In the electroless plating process, sodium hypophosphite serves as a metallizing agent on the metal surface, which can improve the corrosion resistance, wear resistance, uniformity and tightness of the coating. a L Surface metallization: It can metallize the surface of non-metallic materials such as plastics, ceramics, glass, and quartz. 2. Food Field: Sodium hypophosphite is a food additive that can be used as an antioxidant, leavening agent, emulsifier, etc., and is widely used in food processing. For example, it can be used to make cakes, biscuits, bread and other pastry foods, making them softer in taste; at the same time, it can also be used to produce meat products, dairy products, etc., where it can play the roles of stabilizing emulsification and extending the shelf life. 3. Pharmaceutical Field: Sodium hypophosphite has an acid-base neutralizing effect and can neutralize excess acidic substances in the body, thereby maintaining a normal acid-base balance. Therefore, in the medical field, sodium hypophosphite can be used to relieve diseases such as hyperacidemia. In addition, sodium hypophosphite can also be used as a controlled release agent or buffer for drugs, and is used to prepare commonly used drugs, such as heparin, insulin, etc. 4. Daily Chemical Field: Sodium hypophosphite is also used in the manufacture of daily chemicals such as toothpaste and lotion, and has the functions of teeth whitening and oral cleaning. 5. Textile Finishing: In textile finishing, sodium hypophosphite can be used as antioxidant, anti-discoloration agent, dispersant, etc. 6. Scientific Research Application: Sodium hypophosphite is an important raw material for the preparation of other compounds, such as calcium phosphate, carboxymethyl cellulose, etc. In addition, sodium hypophosphite can also be used to prepare metallic sodium, etc. 7. Other Applications: Sodium hypophosphite can also be used to prepare building materials, fertilizers, etc. Among building materials, sodium hypophosphite can increase the corrosion resistance of concrete and improve its wear resistance; and among chemical fertilizers, sodium hypophosphite is one of the important raw materials for phosphorus-containing fertilizers.
