Effect of different binders for refractories description

Therefore, we must be selected for the workpiece material properties, in order to abrasive material good results. Binding agent must have the following properties: high strength, high heat resistance , a suitable hardness, small consumption of grinding , grinding efficiency , the surface roughness of the machined workpiece is better , fillers must be economical, but can be dissolved acid or base , to facilitate recycling . Superhard abrasive material is used as a binder resin material , phenolic resin is widely used , in addition to the epoxy resin , a novel phenol resin, a polyurethane resin, a polyimide resin, and bakelite powder. Brown Corundums can be classified according to the type : inorganic binder and organic binder . Inorganic binders include vitrified , metal bond , magnesite binding agent. Organic binder resin binders include rubber binder. Resin binder itself has good flexibility and polished , the formation of abrasive , still has a good self-sharpening , clogging, less trimming , and high grinding efficiency, low grinding temperature, surface grinding finish, so the wide range of applications . Combine to form a diamond abrasive resin bond diamond abrasive, often applied .
