The hydrophilicity of white corundum is related to what factors

The so-called hydrophilicity is the ability to attract water molecules. There are molecules with polar groups on the surface of many materials, which have a great affinity for water and are easily wetted by water. General abrasives have such properties, and the hydrophilicity of white corundum abrasives is more ideal, which is mainly related to the properties of its materials.
In fact, the quality of the hydrophilic abrasive has a great influence on the degree of bonding with the binder. Generally speaking, the degree of bonding between the abrasive with good hydrophilicity and the binder is stronger; on the contrary, the degree of fusion is worse. For different products, there are large differences in their hydrophilicity, which mainly depends on the processing method, chemical composition and surface quality of the product.
