What are the main applications of industrial grade sodium fluoride?

·The first type is industrial, which is currently the most widely used and has a wide range of applications.

1. Sodium fluoride. Sodium fluoride is an important fluoride salt used in the production of other fluoride raw materials.

Secondly, it is used as an agricultural insecticide, fungicide, wood preservative, water treatment, ceramic pigment, boiling steel manufacturing, light metal fluoride salt treatment agent, etc.

Thirdly, increase the wear resistance in the production of sealing materials and brake pads, and enhance the welding strength by embedding steel into mechanical blade cutters.

4. Adding coagulants to enamel pharmaceutical industry, paper production, and building materials.

In the coating industry, it is used as a phosphating accelerator to stabilize the phosphating solution, refine the phosphating process, and improve the performance of the phosphating film.

·Category 2: Toothpaste grade. As the name suggests, it is mainly added to toothpaste, and adding sodium fluoride to toothpaste can have an anti caries effect. Because the interaction between fluoride and enamel can form fluorapatite on the surface of enamel, improve the hardness and acid resistance of enamel, reduce the formation of plaque, and reduce the incidence rate of dental caries. Fluoride toothpaste does have a certain anti caries effect.

As early as the mid-19th century, Europe had already allowed pregnant women to take oral calcium fluoride to prevent dental caries; In the 20th century, fluoride was recognized worldwide as an effective anti caries agent. In general fluoride toothpaste, the content of sodium fluoride is 0.22-0.33%, and the content of sodium monofluorophosphate is 0.76%. Such a small amount is sufficient to provide good protection for human teeth and reduce the incidence of dental caries by 28%.

·The third type: spherical or sheet-like sodium fluoride. Used as UF3 adsorbent in the nuclear industry, it is used for the adsorption of special gases such as fluorine gas to absorb hydrogen fluoride impurities.

·Category 4: Optical grade sodium fluoride. Mainly used in optical fields such as optical glass and fiber optic crystals.

·Category 5: Battery grade sodium fluoride. Mainly used as an additive in electrolytes or as a raw material for sodium hexafluorophosphate in sodium battery electrolytes.

·Category 6: High purity or reagent grade. This type mainly requires high purity and is generally used as a reagent.
