Two sides of hydrophilicity of white corundum
Corundum not only has the characteristics of high hardness, strong wear resistance, good corrosion resistance and high temperature resistance. There is another characteristic of white corundum that people love and hate. It is the hydrophilicity rarely mentioned. Many people don't know that white corundum has such a characteristic.
Hydrophilicity of white corundum
Hydrophilicity is the ability of an object to attract water molecules.
If the white corundum has good hydrophilicity, the abrasive and binder can bond more firmly in the production of abrasive tools and other aspects, otherwise the degree of combination is poor, and the quality of the abrasive tools produced is not very good.
However, the hydrophilicity of white corundum is too strong, which will bring a lot of troubles, especially when it is stored, it will be infiltrated into white corundum by water and oil stains
Then it can not be removed, sometimes it will lead to white corundum hardening, seriously affecting the quality and use effect of white corundum.
