Title (EN) METHODS FOR REDUCING GLASS SHEET EDGE PARTICLES
(FR) PROCÉDÉS DE RÉDUCTION DE PARTICULES SUR LES TRANCHES D'UNE FEUILLE DE VERRE
Abstract:
(EN) A method of manufacturing a glass article includes application of an etch cream to an edge surface of the article. Application of the etch cream can reduce a density of particles on the edge surface to less than about 200 per 0.1 square millimeter. The etch cream can, for example, contain hydrofluoric acid, hydrochloric acid and a thickener.
(FR) L'invention concerne un procédé de fabrication d'un article en verre, qui consiste à appliquer une crème de gravure sur une surface formant tranche de l'article. L'application de la crème de gravure peut réduire une densité des particules sur la surface formant tranche à moins d'environ 200 pour 0,1 millimètre carré. La crème de gravure peut, par exemple, contenir de l'acide fluorhydrique, de l'acide chlorhydrique et un épaississant.
