Description
本発明の好ましい目的は、結露耐久性と潜熱交換特性(透湿特性)に優れた熱交換用膜エレメントを提供することにある。
すなわち、本発明に係る樹脂製枠体にフィルムを貼設した成形品の製造方法は、1)フィルムを溶剤可溶性又は溶剤崩壊性の補強層で補強し、2)射出成形金型に前記補強されたフィルム(即ちフィルムと補強層との積層体)を挿入し、3)前記金型に樹脂を供給して枠体を射出成形しつつ前記積層体に貼り付け、4)得られた射出成形体を溶剤で処理して補強層を除去することを特徴とする。好ましいフィルムは、延伸多孔質ポリテトラフルオロエチレンフィルムであり、より好ましくは透湿性樹脂が前記延伸多孔質ポリテトラフルオロエチレンフィルムと複合化されている。前記透湿性樹脂は、例えば、ウレタン樹脂、ポリビニルアルコールの架橋体、フッ素系イオン交換樹脂などである。前記溶剤が水の場合、前記補強層は例えば、水溶性繊維で形成されたものである。
本発明には、延伸多孔質ポリテトラフルオロエチレンフィルムが単独で樹脂製枠体に一体成形によって貼設されている熱交換用膜エレメントも含まれる。
図3(a)は本発明で使用する一対の射出成型用金型を側方から見た概略断面図であり、図3(b)は片方の金型の正面図である。なお図3(a)の断面図は図3(b)のI−I’線での切断面に相当する。図4は、図3の金型を用いたインサート成形手順を示す断面図であり、図5(a)は図4の方法で得られた成形品の正面側を示す概略斜視図、図5(b)は前記成形品の背面側を示す概略斜視図である。
空孔率(%)=[1−(D/Dstandard)]×100
フィルム12と補強層15を積層接着したり、積層融着したりする方法は特に限定されないが、例えば、フィルム12と補強層15とを積層した後、熱ロールに通して、熱融着してもよい。
他の溶剤を使用する場合にも、溶剤可溶性又は溶剤崩壊性の材料や溶剤耐久性繊維は、公知の材料から適宜選択できる。
平均孔径0.2μm、空孔率80%、厚さ20μmの延伸多孔質ポリテトラフルオロエチレンフィルムに透湿性ウレタン樹脂を塗布量8g/m2でコーティングした透湿性フィルムにウレタン系接着剤をドット状に転写し、ポリビニルアルコール製不織布((株)シンワ製、商品名「9040−E」)を積層して接着した。
実施例1と同様にして、インサート成形した。透湿性フィルムに積層されたポリビニルアルコール製不織布は、流水で除去することなくそのままにした。
実施例1及び比較例1で得られた成形品の透湿性を、JIS L1099A−1法に準拠して測定した(条件:25℃、75%RH)。3回測定し、その平均値を求めた。結果を表1に示す。
