Title
(EN) METHOD FOR OBTAINING A MATERIAL COMPRISING A GLASS SHEET
(FR) PROCEDE D'OBTENTION D'UN MATERIAU COMPRENANT UNE FEUILLE DE VERRE
Abstract
(EN)
The invention relates to a method for obtaining a material comprising a glass sheet, the method comprising the following steps: - providing a glass sheet having a first face at least partially coated by a first, essentially mineral coating, said face having at least one first area and at least one second area, the at least one first area having a higher emissivity than that of the second area, then - applying, on at least one portion of the second area, a sacraficial layer comprising a resin, then - heat treating the coated glass sheet at a temperature of at least 550°C, during which step the sacrificial layer is removed by combustion.
(FR)
L'invention a pour objet un procédé d'obtention d'un matériau comprenant une feuille de verre, ledit procédé comprenant les étapes suivantes: - la fourniture d'une feuille de verre comprenant une première face revêtue au moins en partie par un premier revêtement essentiellement minéral, ladite face possédant au moins une première zone et au moins une deuxième zone, ladite au moins une première zone ayant une émissivité plus élevée que celle de ladite deuxième zone, puis - l'application, sur au moins une partie de ladite deuxième zone, d'une couche sacrificielle comprenant une résine, puis - le traitement thermique de ladite feuille de verre revêtue à une température d'au moins 550°C, étape au cours de laquelle ladite couche sacrificielle est éliminée par combustion.
