Title (EN) GLASS PLATE WHICH CAN BE REDUCED IN WARPING DURING CHEMICAL TOUGHENING
(FR) PLAQUE DE VERRE APTE À UNE RÉDUCTION DE GAUCHISSEMENT LORS D'UNE TREMPE 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 plate which is capable of effectively suppressing warping after chemical toughening and which is also capable of skipping or simplifying the polishing treatment and the like before chemical toughening. The present invention relates to a glass plate wherein the surface Na2O amount in one surface is lower than the surface Na2O amount in the other surface by 0.2-1.2% by mass.
(FR) Le but de la présente invention est de procurer une plaque de verre adaptée à supprimer efficacement le gauchissement suite à une trempe chimique et qui est également adaptée à omettre ou à simplifier le traitement de polissage et analogue avant ladite trempe chimique. La présente invention concerne ainsi une plaque de verre dans laquelle la teneur en Na2O de surface d'une surface est inférieure de 0,2 à 1,2 % en masse à la teneur en Na2O de surface de 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、一方の面における表面NaO量が、もう一方の面のNaO量濃度よりも0.2質量%~1.2質量%低いガラス板に関する。
