Title (EN) METHOD OF POLISHING AND CLEANING GLASS
(FR) PROCEDE DE NETTOYAGE DE VERRE
Abstract: front page image
(EN)A method of polishing and cleaning a glass surface with a single abrasive article (13, 13'). The abrasive article (13, 13') includes ceria abrasive particles dispersed in binder, the abrasive article having a textured, three-dimensional abrasive coating. The method includes contacting the glass surface with the abrasive article (13, 13') at a desired pressure and in the presence of water, and moving the abrasive article (13, 13') and glass in relation to each other under pressure. The water is believed to mediate a chemical reaction involving the ceria and the glass, thereby leaving a haze on the glass surface. With continued motion of the abrasive article (13, 13') in relation to the glass workpiece, without the addition of additional water, the haze is removed.
(FR)L'invention concerne un procédé de polissage et de nettoyage d'une surface vitreuse à l'aide d'un article abrasif unique. Ledit article abrasif comprend des particules abrasives d'oxyde de cérium dispersées dans un liant, et possède un revêtement abrasif texturé tridimensionnel. Le procédé consiste à mettre en contact la surface vitreuse et l'article abrasif à une pression désirée en présence d'eau, et à déplacer sous pression ledit article abrasif et le verre l'un par rapport à l'autre. L'eau est supposée induire une réaction chimique impliquant l'oxyde de cérium et le verre, ce qui laisse un trouble sur la surface vitreuse. Ledit trouble est éliminé à l'aide d'un mouvement continu de l'article abrasif par rapport à la pièce de verre sans adjonction d'eau supplémentaire.
