Description
ガラス物品: ガラス物品は、任意の大きさのものであってよい。例えばそれは、巻かれた長い超薄ガラスリボン(ガラスロール)、またはガラスロールから切り出された単独のより小さいガラス部材、または別個のガラスシート、または単独の小さいガラス物品(例えばFPSまたはディスプレイのカバーガラス)等であってよい。
本発明によれば、ガラス物品が最大0.07mmの厚さを有し且つ反射光の下で検査される際に可視の光学的なオレンジの皮(OOS)を有さない化学強化されたガラス物品の製造方法は、ガラス表面上で塩残留物の制御された厚さおよび分布をもたらすことによって、より均質なイオン交換工程を提供する。
本発明の1つの態様によれば、最大0.07mmの厚さを有する薄ガラス物品を化学強化するための方法は、以下の段階を含む:
・ ガラス物品を、特定の強化温度を有する溶融塩の浴中に、特定の強化時間の間浸漬させる段階、
・ 強化されたガラス物品を前記塩浴から持ち上げる段階、
・ 強化されたガラス物品を特定の保持時間の間、強化後に保持する段階、ここで、保持温度は、塩浴の融点より高く且つ強化されたガラス物品の転移温度(Tg)よりも低くなるように選択される、
・ 強化されたガラス物品を冷却して洗浄する段階。
Claims (14)
