Potassium cryolite is more suitable for grinding wheel filling material than cryolite

Use in abrasives: PAF (potassium fluoaluminate) is widely used as an organic combination (using resin, rubber or shellac as a binding agent) and the active filling material in the sand belt.
The use of PAF plays an important role in grinding tools, which is manifested in the following aspects.
Improved cutting/grinding performance.
Its low melting point is beneficial to the shedding of the passivated abrasive grains, thus improving the utilization efficiency of other abrasive grains.
The specific performance is to improve the speed of cutting grinding in the unit time, or reduce the wear of the surface of the abrasive in the unit area.
2 improves the heat dissipation performance and reduces the burn or deformation caused by the heating.
In grinding process, fluorine ions can be precipitated out, corrode the metal, and strengthen the grinding function to a greater extent.
4 its fluoride properties can prevent excessive oxidation of grinding surface.
As the reinforcing material in the binding agent, the strength and wear resistance of the settling mixture are improved.
6. Extend the service life of the grinder:
1) better heat dissipation 2) improve the strength and wear resistance of the mixture.

,The above is the characteristics of potassium fluoride in grinding wheel.
