Description
コージェライト組成粉末、結合剤、界面活性剤及び22質量%の水を調合し、混練、土練を行った後、押出成形により、直径144mm、長さ220mm、壁厚75μm、セル数600個/in2(93個/cm2)のハニカム成形体を成形した。
飛散率(%)=(乾燥前の質量−乾燥後の質量)/乾燥前の質量×100
前記実施例1と同様にして同寸法のハニカム成形体を成形した。次いで、マイクロ波出力が200kWである連続式のマイクロ波乾燥器内において、図1に示すように、ベルトコンベアのベルト4上に被乾燥体1としてハニカム成形体を配置し、ハニカム成形体間の距離Aを0mm、60mm、90mm、120mmと変化させ、波長120mmのマイクロ波により各々マイクロ波乾燥を実施し、各ハニカム成形体の水分の飛散率を測定した。結果は、前記実施例1で行ったバッチ式乾燥の場合と同様に、距離Aが90mm以上になると、各ハニカム成形体の飛散率の差がほとんど無くなり、全てのハニカム成形体がほぼ均一に乾燥された。
Claims (5)
- 非直線状に配列された、又は複数列に配列された複数個のハニカム成形体に対しマイクロ波を照射して、前記ハニカム成形体を乾燥する方法であって、前記複数個のハニカム成形体間の距離を前記マイクロ波の波長の3/4以上として乾燥を行うマイクロ波乾燥法。
- 前記複数個のハニカム成形体間の距離を前記マイクロ波の波長の3/4以上、マイクロ波の波長以下として乾燥を行う請求項1に記載のマイクロ波乾燥法。
- 乾燥方法がバッチ式の乾燥方法である請求項1又は2に記載のマイクロ波乾燥法。
- 乾燥方法が連続式の乾燥方法である請求項1又は2に記載のマイクロ波乾燥法。
- 前記マイクロ波の波長が120mmである請求項1ないし4の何れか一項に記載のマイクロ波乾燥法。
