Abstract
【解決手段】幅に亘って長手方向の変化の改善された均一性を有する、可塑剤含有のポリビニルアセタールをベースとするシートの場合に、このシートは、90cmの最小幅の際に20cmまでの縁部で残りのシート領域の厚さの平均値に対して0.1〜4.5%増大された厚さを有する。
【効果】シートとガラスは、一致し、さらに補正またはばり取りなしに後加工することができる。
【選択図】なし
Description
シートの最小の長さは、200cmであるが、しかし、押出方向で10m、50m、100m、200m、500m、1000mまたは2000mに達することができる。
次の組成の可塑剤含有PVB混合物を製造し、321cmの幅および0.76mmの平均厚さを有するシートに加工した。組成Mowital B68 75.5質量%(残留アセテート含量1%未満、PVOH含量約29%)、安定剤Tinuvin PおよびBHTを有するジヘキシルアジペート24.5質量%。付着防止剤として酢酸カリウムを使用した。
図1に記載の均一の厚さプロフィールを有するシートを製造した。相応する大きさのガラス板を有する前積層板を製造した後に、図2aに記載の貼合せ板中の中空空間を観察するかまたは図2bに記載の張り出しているシートの残分を観察した。
WO 2005/070651に記載の0.38mmの厚さおよび5%を上廻る縁部の張出部を有するシートを製造した。図3は、このようなシートの厚さプロフィールを示す。相応する大きさのガラス板を有する前積層板を製造した後に、図4aに記載の貼合せ板中の中空空間を観察するかまたは図4bに記載の張り出しているシートの残分を観察した。それによって製造された前積層板は、付加的に、恐らくシート中での不均一な長手方向の応力分布によってシートの外側の縁部での圧縮部を示した。この結果、気泡または不均一性、例えば光学的障害をまねきうる。図5は、このような前積層板の側面図を示し、この場合Aは、載置前の上側の被覆ガラスを表わし、Bは、下側のガラスを表わし、C(連続線)は、外側縁部でのシートの圧縮による波形かまたは折り畳まれたシート縁部を表わし、D(点線)は、シートの縁部の背後に存在する、シートの中心部での波形でない範囲を表わす。
図6に記載の厚さプロフィールを有するシートを製造した。このシートは、縁部(縁部から最大12cm)で約1.8%増大された厚さを有していた。このシートを用いて製造された合せガラスは、図7に記載された、ガラス縁部に対して平行に延在するシート縁部を有していた。シートとガラスは、一致し、さらに補正またはばり取りなしに後加工することができる。その上、前積層板中でシートの僅かな波形状態のみを観察した。即ち、シートは、ガラス上に殆んど平坦に載置されていた。
