Abstract
Description
例えば全熱交換膜に使用される膜の場合、全熱(顕熱及び潜熱)交換はするが空気(炭酸ガスなど)交換が起こってはならない。よって透湿性樹脂連続層は、透湿性樹脂よりなる無孔質の膜状の層であり、多孔質フッ素樹脂膜の表面に形成される。透湿性樹脂は多孔質フッ素樹脂の一部又は全部に含浸していてもよい。本発明は、透湿性隔膜材料の難燃化を目的とするにも拘わらず、透湿性樹脂連続層を実質的に難燃化していない点に特徴がある。透湿性樹脂連続層が実質的に難燃剤を含有すると、透湿質性隔膜材料の透湿性が低下する。その理由の詳細は不明であるが、難燃剤が透湿性樹脂連続層全体に均一に分散すると、透湿阻害物質として作用するためと思料される。
多孔質フッ素樹脂膜は、透湿性樹脂連続層の保持層として機能する。またフッ素樹脂自体は不燃性であり、透湿性隔膜材料の難燃化に貢献する。
空孔率(%)=[1-(D/Dstandard)]×100
補強用繊維層は、複合膜(多孔質フッ素樹脂膜及び透湿性樹脂連続層)の取り扱い性と強度を高めるため、この複合膜に積層される。補強用繊維層は、複合膜の多孔質フッ素樹脂膜側に積層してもよく、透湿性樹脂連続層側に積層してもよいが、好ましくは透湿性樹脂連続層側に積層する。透湿性樹脂連続層側に積層することで、透湿性樹脂連続層が傷つくのを防止できる。

JIS L 1099(A-1法)に準拠して透湿性隔膜材料の透湿度を調べた。なお温度25℃、相対湿度75%の環境下で透湿度を測定した。
JIS Z 2150 A法に準拠(加熱時間10秒)して透湿性隔膜材料の難燃性を調べた。試験後の透湿性隔膜材料の炭化長を調べ、以下の基準で評価した。
