Treatment of the resin coating liquid: the 125*1*22 EN12413 cutting disc is immersed in a resin mixture composed of a liquid phenol resin and a small amount of a metal oxide such as triiron tetroxide, triiron tetroxide or titanium oxide as described in , for about 30 minutes. Take out and dry to use. Since the resin liquid has good permeability and can penetrate into the tiny pores of the cutting piece, the bonding of the cutting piece to the adhesive is increased, the durability of the grinding tool is improved, and the metal oxide is added to the resin liquid, which is increased. The heat dissipation of the abrasive particles in the abrasive tool is beneficial to the improvement of the efficiency of the abrasive tool.
Silane-coated treatment: Silane, also known as silicone, is a special compound in which silicon and organic genes are chemically reacted to produce inorganic and organic properties. Therefore, the silane-coated cutting sheet is beneficial to the combination of the cutting sheet and the binder. There are two ways to apply: First, the silane solution is directly applied to the surface of the coated dicing sheet. The most ideal and effective thickness of the coating is a single molecule thickness, which is difficult to operate; The simple method is to add the silane directly to the bonded glue. This method is not as effective as the former, but it is easy to handle during production.
