    摘要: A coated abrasive article comprising a backing, an adhesive layer disposed in a discontinuous distribution on at least a portion of the backing, wherein the discontinuous distribution comprises a plurality of adhesive contact regions and at least one shaped abrasive particle is disposed on a majority of each of the discrete adhesive contact regions, wherein at least 50% of the shaped abrasive particles comprise a predetermined side orientation and have a tilt angle of at least 45 degrees, wherein the shaped abrasive particles comprise a polycrystalline material and are free of binder, wherein the first plurality of discrete adhesive contact regions comprise a predetermined two-dimensional shape as viewed from above, and wherein each of the discrete contact regions comprises a length, a width, or a combination thereof that substantially corresponds to a dimension of the at least one abrasive particle.
