The so-called hydrophilicity is the ability to attract water molecules. Many materials have molecules with polar groups on the surface, which have a great affinity for water and are easily wet by water. General abrasives have such properties, and the hydrophilicity of white corundum abrasives is more ideal, which is mainly related to the performance of its materials.
In fact, the quality of hydrophilic abrasives has a greater impact on the degree of bonding of binders, in general, the adhesion of abrasives with good hydrophilicity and binders is strong; Conversely, the degree of integration is worse. For different products, their hydrophilicity varies greatly, mainly depending on the processing method, chemical composition and surface quality of the product.
