Description
本発明には、前記フッ素系弾性チューブを用いたピンチバルブやローラーポンプも含まれる。
空孔率(%)=(ρ2−ρ1)/ρ2×100
二軸延伸多孔質PTFEフィルム(ジャパンゴアテックス(株)製「ePTFEフィルム」、幅:400mm、長さ(奥行き):816mm、空孔率:78%、最大細孔径:0.4μm、厚さ:18μm)に、片側から液状フッ素ゴム(信越化学工業(株)製「SIFEL−617」)を塗布し、多孔質PTFEフィルムの細孔に充填した。塗布面を内側にしながら、かつ空気を巻き込まないようにしつつ、この塗布フィルムをステンレス鋼棒材(外径:5mm)に巻き付けた。温度150℃で30分間加熱することにより、液状フッ素ゴムを架橋した。
旭硝子(株)製のアモルファスパーフルオロ樹脂(商品名「サイトップ」)を使用して内面に厚さ0.5μmのアモルファスパーフルオロ樹脂膜20を形成する以外は、実施例1と同様にしてフッ素系弾性チューブ1を得た。
アモルファスパーフルオロ樹脂膜20に代えて、旭硝子(株)製のアモルファス部分フッ素樹脂(商品名「ルミフロン」)を使用して内面に厚さ10μmのアモルファス部分フッ素樹脂膜を形成する以外は、実施例1と同様にして弾性チューブ1を得た。
二軸延伸多孔質PTFEフィルムの細孔内に充填するゴムを液状シリコーンゴム(信越化学工業(株)製「KE106」)にする以外は、実施例1と同様にしてフッ素系弾性チューブ1を得た。
外径:300mm、幅:600mm、耐圧延反力:1MN(最大)のカレンダーロール装置を用い、ロール温度:70℃、線圧:8N/mm2、送り速度:6m/分の条件で二軸延伸多孔質PTFEフィルム(ジャパンゴアテックス(株)製の「ePTFEフィルム」、幅:500mm、空孔率:90%、厚さ:20μm)を圧縮し、幅:500mm、長さ:500mm、空孔率:5%、厚さ2.1μmの白濁色のフィルムを得た。この白濁フィルムを2枚のポリイミドフィルム(宇部興産(株)製の「ユーピレックス20S」(商品名))の間に挟み、プレス面の大きさ:750mm×750mm、最大加圧力:2MNのホットプレス装置を用いて、プレス板温度:400℃、面圧:10N/m2の条件で5分間加熱プレスした後、面圧を保持した状態で60分かけて徐々にプレス板温度を25℃まで冷却することにより、幅:500mm、長さ:500mm、空孔率:0%、厚さ:2μmで、透明なPTFEフィルム(緻密化PTFEフィルム)を得た。
ウェットプロセス用樹脂製ピンチバルブ(旭有機材工業(株)製、商品名「Dymatrix AVPV3」)にフッ素系弾性チューブ1を装着した。このピンチバルブは、15mm×10mmの角柱状ピストン(先端の周縁部は、面取りされている(曲率0.4))を付属のスプリングで平板体に向けて押しつけつつ、圧縮空気で前記ピストンを押し戻すことで、ピストンの押圧力を制御できる様になっている。ピストンと平板体との間にチューブを挿入し、チューブ内に液体を通液することなく、ピストンで弾性チューブを繰り返し押圧した。押圧の条件は、以下の通りである。
押圧時間:1.5秒/回
圧力解放時間:1.5秒/回
スプリングによる最大押圧力:1.3MPa
圧縮空気圧:0.4MPa
チューブ内面のフッ素樹脂膜が剥離するまでの繰り返し数をカウントした。
チューブ内にプロピレングリコールモノメチルエーテルアセテート(PGMEA)を通液する以外は、前記1)耐久性と同様に試験した。
前記ウェットプロセス用樹脂製ピンチバルブ(旭有機材工業(株)製、商品名「Dymatrix AVPV3」)の入口側配管と出口側配管をつなぐ様にフッ素系弾性チューブ1を装着し、ピストンで該チューブ1を押圧した。出口側配管の開放端を水深20mmの高さに水没させ、入口側配管の開放端を圧縮空気(0.4MPa)で30秒間加圧し、出口側配管からの気泡の発生を目視で確認した。30秒間加圧しても気泡が発生しない場合を「良好」と判定し、30秒間の加圧中に気泡が発生した場合を「不良」と判定した。
結果を表1に示す。
10 弾性中空体
20 アモルファスパーフルオロ樹脂膜(フッ素樹脂膜)
12 フッ素系エラストマーからなる層
13 フッ素系エラストマーを充填した多孔質フッ素樹脂からなる層
