Abstract
Description
(a)ハニカム構造体の一方の端面上にマスクを配置する工程と、
(b)ハニカム構造体の一方の端面における封口すべきセルの開口にマスクが有する第1の貫通孔を通じて封止材を供給する工程と、
を備え、マスクはハニカム構造体の一方の端面と当接する領域に、当該マスクの厚さ方向に貫通する複数の第1の貫通孔を有し、第1の貫通孔の開口面積は、0.03mm2以上であり且つ当該第1の貫通孔によって封口すべきセルの開口面積の90%未満である封口方法を提供する。
(c)ハニカム構造体の他方の端面上に他のマスクを配置する工程と、
(d)ハニカム構造体の他方の端面における封口すべきセルの開口に上記他のマスクが有する第3の貫通孔を通じて封止材を供給する工程とを更に備えてもよい。この場合、上記他のマスクは、ハニカム構造体の他方の端面と当接する領域に、当該マスクの厚さ方向に貫通する複数の第3の貫通孔を有し、第3の貫通孔の開口面積は、0.03mm2以上であり且つ当該第3の貫通孔によって封口すべきセルの開口面積の90%未満であることが好ましい。
図1の(a)に示すように、ハニカム構造体1は、多数のセル1aが略平行に配置された円柱体である。セル1aはハニカム構造体1の一方の端面から他方の端面にかけて貫通している。セル1aの断面形状は、図1の(b)に示すように正方形である。これらの複数のセル1aは、ハニカム構造体1において、端面から見て、正方形配置、すなわち、セル1aの中心軸が、正方形の頂点にそれぞれ位置するように配置されている。セル1aの断面の正方形のサイズは、たとえば、一辺0.8~2.5mmとすることができ、その開口面積は0.6~7.0mm2程度(より好ましくは0.8~6.0mm2程度)とすることができる。ハニカム構造体1のセルピッチは、1.1~2.8mmとすることができる。なお、セルピッチとは、隣接する2つのセルの中心間の距離を意味し、ハニカム構造体1にあっては図1の(b)に示す長さLである。
図2に示すマスク5は、図1に示すハニカム構造体1の所定のセルを封口するのに使用されるものである。マスク5は、円形の板状部材であり、厚さ方向に貫通する第1の貫通孔5a及び第2の貫通孔5bを有する。なお、マスク5の材料は特に限定されず、たとえば、金属や樹脂が挙げられる。また、マスク5の貫通孔5aの位置決めを容易にすべく、マスク5には、オリエンテーションフラット5cが形成され、これに対応して図3に示す封口装置100のリング部材25にもオリエンテーションフラット5cに対応する突起25bを設けてもよい(図4参照)。また、マスク5の外径は、封口装置100の本体部10の凹部10dの内径よりも大きくされていることが好ましい。
マスク5を用いてハニカム構造体1の封口を実施するのに好適な封口装置について説明する。図3に示す封口装置100は、主として、本体部10、弾性板20、ポンプ50及び保持部80を備える。
本実施形態に係る封口方法は、マスク5を用いてハニカム構造体1の所定のセルの開口を封止するためのものである。より具体的には、この封口方法は以下の工程を備える:
(a)ハニカム構造体1の一方の端面上にマスク5を配置する工程;及び
(b)ハニカム構造体1の一方の端面における封口すべきセルの開口にマスク5の第1の貫通孔5aを通じて封止材を供給する工程。
(c)ハニカム構造体1の他方の端面上に他のマスク5´を配置する工程;及び
(d)ハニカム構造体1の他方の端面における封口すべきセルの開口にマスク5´の第3の貫通孔5a´を通じて封止材を供給する工程;
を順次実施する。
