| 摘要 |
Discontinuous abrasive particle releasing surfaces are disclosed that may be employed in low speed wet grinding, sanding, and polishing operations. The discontinuous abrasive surfaces of the present invention may consist of abrasive containing protrusions attached to rigid or flexible surfaces or alternatively may be comprised of closed cell foam compositions impregnated with abrasive materials such as aluminum oxide. The voids present in the discontinuous abrasive surfaces of the present invention serve to hold water and remove debris. The resulting discontinuous abrasive particle releasing surfaces are long lasting and may be made low in cost.
