Abstract
【解決手段】所望の形状に機械加工された基材の、方向が異なる複数の表面をフッ素樹脂で被覆するフッ素樹脂被覆工程と、前記基材に対して一方向から電子線を窒素雰囲気中で照射して、前記複数の表面を被覆するフッ素樹脂を架橋する照射工程と、を有することを特徴とする架橋フッ素樹脂被覆層を有する立体形状物の製造方法。
【選択図】図1
Description
図2で示すような電子線照射装置を使用し、照射ゾーン中に置かれた1.8L炊飯釜(図3)及び水平台(図4)に、下記の測定条件で、電子線を照射し、炊飯釜及び水平台の表面に設けられた照射線量測定フィルム(図中では「測定フィルム」と表す。)により、電子線照射量(照射面が受けた線量)を測定した。その結果を表1に示す。
純窒素中(酸素含量5ppm以下)で照射、常温
加速器:日新電機社製サガトロン
加速電圧:1.13MeV
電流値:10mA
トラバース速度:2.61m/分
電子線照射口から、照射ゾーン底面までの距離:60cm
トラバース回数を1〜3に変えて、実際の照射量を変えた。
照射線量測定フィルム:富士フィルム社製CTAフィルム
図2は、実施例で使用した電子線照射装置を概念的に示す概念平面図である。この電子線照射装置は、電子線を照射する手段(加速器、以下単に「照射手段」と言う。)を有し、この照射手段は、図中の矢印で示す方向にトラバース(進行)し、進行方向とは垂直な方向に電子線を走査しながら、照射ゾーン(図中の点線が囲まれた部分)に置かれた炊飯釜、水平台へ、炊飯釜底面や水平台上面に向かう1方向(紙面の上方から下方に向かう方向)で電子線を照射する。
Claims (3)
- 所望の形状に機械加工された基材の、方向が異なる複数の面をフッ素樹脂で被覆するフッ素樹脂被覆工程と、前記基材に対して一方向から電子線を窒素雰囲気中で照射して、前記複数の面を被覆するフッ素樹脂を架橋する照射工程とを有することを特徴とする架橋フッ素樹脂被覆層を有する立体形状物の製造方法。
- 前記照射工程において、立体形状物を、フッ素樹脂の結晶融点よりも0〜30℃高い温度に加熱して電子線を照射することを特徴とする請求項1に記載の架橋フッ素樹脂被覆層を有する立体形状物の製造方法。
- 前記立体形状物が、炊飯釜又は鍋でありその内表面の底面及び側面にフッ素樹脂が被覆されていることを特徴とする請求項1又は請求項2に記載の架橋フッ素樹脂被覆層を有する立体形状物の製造方法。
