Properties of resin binder are introduced Resin binders are used to bond loose abrasives, solidify into a certain shape, and after heating and cementing, they have a certain degree of hardness, strength and grinding performance. The resin binders are composed of binders (resins) and various fillers. The physical and mechanical properties of the binder are greatly influenced by the type and amount of filler. Therefore, the type and amount of filler must be chosen reasonably. Resin bond should have the following properties: good bonding performance, strength of the bond should be high, hardness should be appropriate; Good heat resistance can improve the grinding efficiency and reduce the surface roughness of the workpiece. Good economy and environmental protection. The resin that makes resin abrasive tool commonly is man-made phenolic resin, epoxy resin, polysulfone resin, polyamide. For the special requirement of quartz grinding tool, mainly phenolic resin, some other resin is added. S...
