Title
(EN) METHOD FOR PRODUCING SURFACE-TREATED GLASS SUBSTRATE
(FR) PROCÉDÉ DE FABRICATION D'UN SUBSTRAT DE VERRE TRAITÉ EN SURFACE
(JA) 表面処理されたガラス基体の製造方法
Abstract
(EN)
The present invention efficiently obtains in a short period of time a glass substrate having a low refraction index layer exhibiting excellent properties in which the refraction index is low. A glass substrate is produced by subjecting at least one surface of a glass substrate, that is being conveyed when the temperature of the glass substrate is within 400°C and Tg+60°C (Tg being the glass transition temperature of the glass substrate), to surface treatment by bringing the glass substrate into contact with liquid or gas containing molecules having fluorine atoms in the structure thereof.
(FR)
La présente invention concerne un procédé permettant d'obtenir efficacement, en une période courte de temps, un substrat de verre ayant une couche à faible indice de réfraction présentant d'excellentes propriétés, dans laquelle l'indice de réfraction est bas. On obtient un substrat de verre en soumettant au moins une surface d'un substrat de verre, qui est transporté lorsque la température du substrat de verre se situe dans les 400°C et Tg+60°C (Tg étant la température de transition vitreuse du substrat de verre), à un traitement de surface en amenant le substrat de verre en contact avec un liquide ou un gaz contenant des molécules ayant des atomes de fluor dans leur structure.

 屈折率の低い優れた性能の低屈折率層を有するガラス基体を、短時間に効率よく得る。 ガラス基体の少なくとも一面に、該ガラス基体のガラス転移温度をTgとした場合に、該ガラス基体の温度が400℃~Tg+60℃の範囲で搬送中のガラス基体に対して、その構造中にフッ素原子が存在する分子を含有する気体もしくは液体を接触させることにより表面処理を行うことによりガラス基体を製造する。
