Title (EN) GLASS SHEET CAPABLE OF BEING INHIBITED FROM WARPING THROUGH CHEMICAL STRENGTHENING
(FR) FEUILLE DE VERRE POUVANT ÊTRE EMPÊCHÉE DE SUBIR UN GAUCHISSEMENT PAR UN RENFORCEMENT CHIMIQUE
(JA) 化学強化時の反りを低減できるガラス板
Abstract:
(EN) The purpose of the present invention is to provide a glass sheet which can be effectively inhibited from warping through chemical strengthening and which enables polishing, etc., as treatments to be conducted before chemical strengthening, to be omitted or simplified. The invention relates to a glass sheet in which the degree of enrichment with fluorine in one of the surfaces is higher by at least 5 than the degree of enrichment with fluorine in the other surface.
(FR) La présente invention a pour but de proposer une feuille de verre qui peut, de façon efficace, être empêchée de subir un gauchissement par un renforcement chimique et qui permet à un polissage, etc., en tant que traitements à conduire avant le renforcement chimique, d'être omis ou simplifié. L'invention concerne une feuille de verre dans laquelle le degré d'enrichissement par du fluor dans l'une des surfaces est supérieur à au moins 5 au degré d'enrichissement par du fluor dans l'autre surface.
(JA)  本発明は、化学強化後の反りを効果的に抑制することができるとともに、化学強化前の研磨処理等を省略または簡略化することができるガラス板を提供することを目的とする。本発明は、一方の面におけるフッ素富化度が、もう一方の面における表面フッ素富化度より5以上大きいガラス板に関する。
