Description
・ 固有の耐擦傷性および耐引掻性のために、これらのガラスを強化する必要がなく、したがって、これらのガラスは、フルシートとして、処理されイオン交換されたSLSガラスがレーザ切断されたSLSである場合に典型的に見られる結果として生じた反りがなく、次いで、レーザ切断することができる;
・ ダウンドロー法を使用して形成された無アルカリアルカリ土類アルミノケイ酸塩ガラスを使用すると、無垢な薄いガラス(0.1〜1mm厚)を使用できるのに対し、SLSガラスは、典型的に、これらのより薄い仕様を達成するために研磨が必要であろう;
・ イオン交換プロセスがないことは、イオン交換ガラスは、最小のイオン移動度および結果として生じる強度の変化を確実にするために交換温度より低く処理する必要があるので、処理温度が、イオン交換ガラスにおけるよりも、高くて差し支えないことを意味する;
・ 開示された無アルカリアルカリ土類アルミノケイ酸塩のタッチスクリーン用ガラスは、典型的にディスプレイ用ガラスと密接に一致した耐擦傷性を示し、これは転じて、ITOガラスのディスプレイ用ガラスとの将来的なハイブリッド組込みが可能になる;
・ イオン交換がないことは、均一であり、部分的に応力下でも部分的に張力下でもない縁を意味し、これは、適切なサイズに切断されたときに、上面と下面のみが化学強化され、縁の中は強化されておらず張力下にある縁を示すSLSガラスの特徴と対照的である。その結果、無アルカリアルカリ土類アルミノケイ酸塩タッチスクリーン基板は、張力下にある露出縁を有する基板に典型的に存在する、時間の経過と共に縁の強度の減少をもたらすガラス中の疲労効果による置割れの傾向がない。これらの遅延した疲労効果は、ガラスが曝露されたであろう温度または湿度もしくはそれらの組合せに相関するようである。
