The invention provides a super-sharp
ceramic tile
cutting disc which comprises a base body and a
cutting part located on the edge of the base body, and the
cutting part comprises, by weight, 65-80 parts of
diamond particles, 10-25 parts of an
iron pentacarbonyl compound, 35-55 parts of a binding agent and 30-40 parts of
copper-coated carbon with the particle size being 0.5-0.6 mm. According to the super-sharp
ceramic tile cutting disc, the
copper-coated carbon compound is applied, so that the cutting efficiency is improved;
copper-coated carbon and
diamond particles are combined more firmly, the cutting efficiency is higher, the edge breakage effect of the
ceramic tile is effectively improved, the
iron pentacarbonyl compound is applied and serves as a catalyst, so that the combination is firmer, the
hardness is effectively improved, paraffin is gradually burnt in the
sintering process, pores are formed,
diffusion channels are provided by the pores, and the service life of the ceramic tile is prolonged. By means of the method, atoms or molecules among particles can be migrated more easily, combination among the particles is promoted, along with rising of the
sintering temperature, pores begin to be closed gradually, the contact area among the particles is increased, the particles begin to be rearranged, and the abrasion resistance and
hardness are effectively improved.
