Wide range of uses

1. Sodium fluoride (NAF) is an important fluoride salt used to make other fluoride raw materials.

2. Used as agricultural pesticide and sterilization

3. Used as wood preservative, water treatment agent, ceramic pigment, boiling steel manufacturing, light metal fluoride salt treatment agent, smelting refining and protective layer, as UF3 adsorbent in nuclear industry.

4. In the production of sealing materials and brake pads, wear resistance has been increased. The mechanical blade planer inserts steel to increase the welding strength.

5. Enamel pharmaceutical industry, paper production and construction materials.

6. Used as a phosphating accelerator in the coating industry to stabilize the phosphating solution, refine the phosphating film, and improve the performance of the phosphating film. In the phosphating of aluminum and its alloys, AL3+, which has a very harmful negative catalytic effect, is blocked, so that the phosphating can proceed smoothly, and an alkaline zincate zinc plating additive. Cleaning fluid for steel and other metals, welding flux and flux.

7. Spiritual flux and sunscreen for ceramic glass and enamel, hide and skin treatment in leather industry, glue anticorrosion.
