Abstract
【解決手段】複数のハニカムセグメント2が接合材層9を介して互いの接合面で一体的に接合されたハニカムセグメント接合体10と、外周コート層4とを備え、流体の流路となる複数のセル5が中心軸方向に互いに並行するように配設された構造を有するハニカム構造体1であって、外周コート層4の、中心軸方向に垂直な方向の断面における接合材層9の長手方向端面上に位置する部分(端面上部分)4Aの少なくとも1箇所の厚さが、端面上部分4A以外の部分における平均厚さよりも厚くなるように構成する。
【選択図】図1
Description
(ハニカムセグメントの作製)
寸法が35mm×35mm×150mmL、隔壁厚さ約300μm(12mil)、セル密度約47セル/cm2(300セル/平方インチ)のハニカムセグメントを作製した。
作製したハニカムセグメントにスラリー状の接合材を塗布して接合して乾燥硬化してハニカムセグメント接合体を作製した後、切削し、次いでスラリー状の外周コート材を塗布して外周コート層を形成し、直径144mm×長さ152mmのDPF用の円柱状ハニカム構造体を作製した。この場合、外周コート層の最大厚さ(t1)を、最大の厚さを有する部分以外の部分における平均厚さ(t2)の2倍とした。
外周コート層の厚さを表1に示す厚さに変えたこと以外は実施例1と同様にして9種類のハニカム構造体を作製した。
実施例及び比較例で得られたハニカム構造体を、表1に示す7種類の設定温度に加熱した状態の炉の中に投入し、ハニカム構造体の内部が設定温度になるまで1時間保持した後、炉外へ取り出し、ハニカム構造体が常温になったときの外周コート層上のクラックの発生の有無を確認することで、外周コート層の部分による厚さの相違に起因するクラックの発生限界の相違を評価した。クラック評価の判定は、クラックなしを(○)、クラック有りを(×)とした。その結果を表1に示す。表1から、比較例1(t1がt2の等倍で、かつt3がt4の等倍の時)では設定温度が300℃でクラックが発生した。それに対し、実施例1〜9のように、t1の厚さをt2の2倍以上(2倍〜40倍)およびt3の厚さをt4の2倍以上(2倍〜40倍)に増加させる程、クラックが発生する設定温度は高くなった。すなわち、外周コート層の所定部分の厚さを厚くするほどクラック発生限界が向上することが分かった。
