Usage
1. Sodium fluoride is mainly used as Inlaid steel for mechanical blade and planer to enhance weld strength. Secondly, it is used as wood preservatives, fungicides in brewing industry, agricultural pesticides (should be infected with blue), medical preservatives, welding flux, fluorine agent for drinking water. Also used for producing other fluoride and casein glue, sodium fluoride toothpaste, as adhesives, also used in paper and metallurgical industries. In the production of elemental fluorine, it is used for removing trace amounts of hydrogen fluoride. In addition, it is also used in enamels and pharmaceutical industries.
2. Sodium fluoride is used as disinfectants, preservatives, pesticides, also used in enamel, wood preservation, medicine, metallurgy, manufacturing of fluorides and so on.
3. Used for determination of scandium in microanalysis, determination of phosphorus in photoelectric colorimetric analysis, used as reagent, the masking agents, preservatives of iron and steel.
4. As food supplements. According to Chinese regulations for salt, the maximum usage is 0.1g/kg.
5. It is used as wood preservatives, pharmaceutical preservative, welding flux and used in paper industry, this company's products are specific level toothpastes, can also be used as purifying agent for drinking water, and used for hides and skin processing in tanning industry, for smelting and refining of light metal, and protection layer of light metal, for adhesive corrosion, and manufacturing boiling steel.
6. Sodium fluoride is used as the Phosphate accelerator in coating industry, makes phosphating solution stability, phosphate refinement, improves the performance of phosphate coating. Aluminum and its alloys phosphate can close negative catalytic Al3 + of great danger, and make phosphating smoothly. It is used as wood preservatives, agricultural pesticides, fungicides in brewing industry, pharmaceutical preservative, welding flux, alkaline zincate zinc additives and enamel, paper and so on.
