Zusammenfassung: | This paper describes newly developed non-foaming polishing pads for polishing glassware. A polyamide-based epoxy resin instead of a conventional polyamine-based epoxy resin or a polyurethane resin, is employed. The polyamide-based epoxy resin has a beneficial effect on hydrophilic property and abrasive retention of polishing pads. It was found that the material removal rate of glass using the polyamide-based epoxy-resin polishing pad is higher than that using the polyamine-based epoxy-resin pad or the commercially available polyurethane-resin polishing pad. It was confirmed that the surface roughness of glass polished by the novel polyamide-based epoxy-resin pads is better than that polished by the urethane pad. The contained amount of polyamide-based curing agent in polyamide-based epoxy-resin polishing pads was altered, but not changed the hardness of polishing pads by adjusting mixing ratio of polyamine-based curing agents. The material removal rate increases with the amount of polyamide-based curing agent contented in epoxy resin. What’s more, the reason of high material removal rate with using the polyamide-based epoxy-resin polishing pad was also investigated. The contact angles of slurry on polishing pads and the surface states of various pads after polishing test were measured. The results showed that, the hydrophilicity of polyamide-based epoxy-resin pads is higher and a finer concave-convex surface generates in polishing process. The hydrophilicity and the finer concave-convex surface are suitable for polishing pads to improving the polishing performance. The surface states of polishing pads can be altered with mixing more than two kinds of curing agents in epoxy resin. |
