Sodium fluoride product introduction
Application field
1, sodium fluoride is an important fluoride salt, is the manufacture of other fluoride raw materials.
2, used in agricultural insecticides, has bactericidal effect.
3, as wood preservative, water treatment agent, ceramic pigment, boiling steel manufacturing, light metal fluoride treatment agent, smelting and refining and as a protective layer, used as UF3 adsorbent in the nuclear industry.
4. Increase wear resistance in the production of sealing materials and brake pads. Mechanical planer inserts steel to increase welding strength.
5, enamel pharmaceutical industry and paper production and building materials.
6, as a phosphating accelerator in the coating industry, the phosphating liquid is stable, the phosphating refinement, and the phosphating film performance is improved. Al3+, which has a harmful negative catalytic effect, is blocked in the phosphating of aluminum and its alloys, so that the phosphating can be carried out smoothly, and the basic zincate galvanizing additive. Cleaning fluids for steel and other metals, welding fluxes and fluxes.
7, ceramic glass and enamel spiritual flux and shading agent, leather industry raw skin and skin treatment, adhesive anticorrosive.
