Description
また、本発明によるPTFE多孔体は、気孔の形状が方向性を有し、該気孔が特定の一方向に対して長い形状であるバルク型のものである。
また、本発明によるバルクフィルタは、上記PTFE多孔体からなり、上記バルクフィルタを物質が透過する方向の気孔径をX、Xに直行する方向の気孔径をYとしたとき、それぞれの気孔においてのX/Yを平均すると1を超えるものである。また、気−液分離をすることが可能であるものが考えられる。
PTFE粉末100重量部とショウノウ137.5重量部を、回転刃を有するミキサーにてせん断応力を加えながら一体化処理を約6分間行った後、ナフサ12.5重量部を添加して上記ミキサーにて更に1分間混合し、PTFE混合体を得た。このPTFE混合体を内径20mmの円筒状のシリンダー内で約40kgf/cm2で30秒間圧縮して仮成形した後、押出機にて外径約5mmに押出成形した。この成形体を250℃で約5分間加熱処理してショウノウとナフサを気化させて除去した後、400℃で約5分間の加熱焼成処理をして外径約5mmのサンプル片を作製した。
PTFE粉末100重量部と安息香酸125重量部を、回転刃を有するミキサーにてせん断応力を加えながら一体化処理を約6分間行った後、ナフサ25重量部を添加して上記ミキサーにて更に1分間混合し、PTFE混合体を得た。このPTFE混合体を内径20mmの円筒状のシリンダー内で約40kgf/cm2で30秒間圧縮して仮成形した後、押出機にて外径5mmに押出成形した。この成形体を250℃で約5分間加熱処理して安息香酸とナフサを気化させて除去した後、400℃で約5分間の加熱焼成処理をして外径約5mmのサンプル片を作製した。
