COLUMNAR HONEYCOMB STRUCTURE FILTER AND PRODUCTION METHOD OF THE SAME
To provide a columnar honeycomb structure filter contributing to both of PN high collection efficiency and low pressure loss.SOLUTION: A columnar honeycomb structure filter is provided with: a plurality of first cells enlarging from an inlet side bottom surface to an outlet side bottom surface, opening the inlet side bottom surface and having a sealing part on the outlet side bottom surface; and a plurality of second cells enlarging from an inlet side bottom surface to an outlet side bottom surface, having a sealing part on the outlet side bottom surface and opening the outlet side bottom surface. In the columnar honeycomb structure filter, the plurality of first cells and the plurality of second cells are alternately and adjacently arranged in a state of sandwiching a porous partition wall, and a ceramic porous film, which has an average film thickness T (unit:μm) of 2-50 μm and a porosity P (unit:%) of 65-90%, where the average film thickness T and the porosity P satisfy a relational expression of 0.36T+60≤P≤0.75T+72, is formed on the surface of each first cell.SELECTED DRAWING: Figure 3
【課題】ＰＮ高捕集効率及び低圧力損失の両立に寄与する柱状ハニカム構造フィルタを提供する。【解決手段】入口側底面から出口側底面まで延び、入口側底面が開口して出口側底面に目封止部を有する複数の第１セルと、入口側底面から出口側底面まで延び、入口側底面に目封止部を有し、出口側底面が開口する複数の第２セルとを備え、複数の第１セルと複数の第２セルは多孔質隔壁を挟んで交互に隣接配置されている柱状ハニカム構造フィルタであって、それぞれの第１セルの表面には、平均膜厚Ｔ（単位：μｍ）が２〜５０μｍ、気孔率Ｐ（単位：％）が６５〜９０％であり、平均膜厚Ｔと気孔率Ｐが０．３６Ｔ＋６０≦Ｐ≦０．７５Ｔ＋７２の関係式を満たすセラミックス製の多孔質膜が形成されている柱状ハニカム構造フィルタ。【選択図】図３
