Abstract
Description
図1に戻ると、ガラス積層体10の第1のペイン12は、ガラス‐ガラス積層構造100を備える。ガラス‐ガラス積層構造100は、第1のクラッド層104と第2のクラッド層106との間に配置されるコア層102を備える。いくつかの実施形態では、第1のクラッド層104及び第2のクラッド層106は、図1に示すように外層である。他の実施形態では、第1のクラッド層及び/又は第2のクラッド層は、コア層と外層との間に配置される中間層である。
第1の層(例えばコア層102)の第1のガラス組成物、並びに第2の層(例えば第1のクラッド層104及び/又は第2のクラッド層106)の第2のガラス組成物は、本明細書に記載の所望の特性を有するガラス‐ガラス積層構造を形成できる好適なガラス組成物を含むことができる。
いくつかの実施形態では、略透明なコーティングは、化学強化ガラスシートの1つ以上の表面の表面CSの低減に寄与する。例えば、略透明なコーティングは、イオン交換の前にガラスシートの1つ以上の表面上にコーティング又は配置された、多孔質ゾルゲルコーティングを含むことができる。コーティングの多孔性により、コーティングを通したイオン交換を、ガラスシート中へのイオンの拡散がコーティングにより部分的に阻害されるような方法で、可能とすることができる。これは、化学強化ガラスシートのコーティング済み表面において、非コーティング表面に比べて、低いCS及び/又は低いDOLをもたらし得る。コーティングは、化学強化ガラスシートのコーティング済み表面に定められたCSを提供するために、定められた多孔性を有することができる。化学強化ガラスシートの2つの対向する表面間の圧縮応力の有意な不均衡は、ガラスシートの若干の曲がりをもたらし得る。このような曲がりは、本明細書に記載されるような、第2のペインの化学強化ガラスシートの第1のペインに対する冷間成形を補助できる。いくつかの実施形態では、イオン交換により誘発される曲がりは、冷間成形後の最終的な積層体において望ましい量の曲がり又は屈曲よりわずかに小さい。イオン交換前に透明なコーティングが塗布されるいくつかの実施形態では、透明なコーティングを加工する又は硬化させる温度は、他の実施形態におけるものより高くてよく、例えば500℃又は600℃もの高さである。
図1に示されているものと同様のガラス積層体を形成した。第1のペインは、厚さ約1mmのガラス‐ガラス積層構造であった。クラッド層の厚さ(両方のクラッド層の厚さの合計)に対するコア層の厚さの比は、約6であった。クラッド層の圧縮応力は約150MPaであり、コア層の中心張力は約25MPaであった。中間層はPVBから形成され、約0.8mmの厚さを有していた。第2のペインは、厚さ約0.4mmの化学強化ガラスシートであった。
図1に示されているものと同様のガラス積層体を形成した。第1のペインは、厚さ約1mmのガラス‐ガラス積層構造であった。クラッド層の厚さ(両方のクラッド層の厚さの合計)に対するコア層の厚さの比は、約9であった。クラッド層の圧縮応力は約190MPaであり、コア層の中心張力は約21MPaであった。中間層はPVBから形成され、約0.8mmの厚さを有していた。第2のペインは、厚さ約0.4mmの化学強化ガラスシートであった。
ガラス積層体を形成する。第1のペインは、厚さ約1mmのガラス‐ガラス積層構造であった。中間層はPVBから形成され、約0.8mmの厚さを有していた。第2のペインは、厚さ約0.5mmのガラス‐ガラス積層構造であった。
図1に示されているものと同様のガラス積層体を形成した。第1のペインは、表2に示すように実施例4A〜4D間で変動する特性を有する、ガラス‐ガラス積層構造又は機械強化ガラスシートであった。各実施例4A〜4Dにおいて、第2のペインは、厚さ約0.7mm、CS約700MPa、及びDOL45μm(FSMで測定)の化学強化ガラスシートであった。中間層は、第1のペインと第2のペインとの間に配置された接着テープであった。
