Title (EN) METHOD FOR MANUFACTURING REINFORCED GLASS PLATE
(FR) PROCÉDÉ DE PRODUCTION D’UNE PLAQUE DE VERRE RENFORCÉE
(JA) 強化ガラス板の製造方法
Abstract:
(EN) This method for manufacturing a reinforced glass plate allows ions on a glass plate surface layer to be exchanged. The method for manufacturing a reinforced glass plate is characterized by including: a selective reinforcing step of making the thickness of a selected area set on a portion of the surface of the glass plate greater than the thickness of a non-selected area other than the selected area, and forming a deeper compressive stress layer in the selected area than in the non-selected area by the exchange of ions; and a flattening step of flattening the main surface of the glass plate by removing at least a portion of the selected area that expanded in the selective reinforcing step.
(FR) La présente invention concerne un procédé de fabrication d'une plaque de verre renforcée permettant l'échange d'ions sur une couche de surface de la plaque de verre. Le procédé de fabrication d'une plaque de verre renforcée est caractérisé en ce qu'il comprend : une étape de renforcement sélectif consistant à rendre l'épaisseur d'une zone sélectionnée fixée sur une partie de la surface de la plaque de verre supérieure à l'épaisseur d'une zone non sélectionnée autre que la zone sélectionnée, et à former une couche de contrainte de compression plus profonde dans la zone sélectionnée que dans la zone non sélectionnée par l'échange d'ions ; et une étape d'aplanissement consistant à aplanir la surface principale de la plaque de verre par élimination d'au moins une partie de la zone sélectionnée qui s'est dilatée lors de l'étape de renforcement sélectif.
(JA) 本発明の強化ガラス板の製造方法は、ガラス板表層のイオンを交換する強化ガラス板の製造方法であって、イオンの交換により、ガラス板の表面の一部に設定した選択領域の厚みを、当該選択領域以外の非選択領域よりも大きくするとともに、選択領域において非選択領域よりも深い圧縮応力層を形成する選択強化工程と、選択強化工程において膨張した選択領域の少なくとも一部を除去することにより、当該ガラス板の主面を平坦化する平坦化工程と、を備えることを特徴とする。
