Columnar honeycomb structure filter and its manufacturing method |
| abstract |
PROBLEM TO BE SOLVED: To provide a columnar honeycomb structure filter which contributes to both high PN collection efficiency and low pressure loss. SOLUTION: A plurality of first cells extending from the bottom surface of the inlet side to the bottom surface of the exit side, the bottom surface of the inlet side is opened and having a sealing portion on the bottom surface of the exit side, and the bottom surface of the inlet side extends to the bottom surface of the exit side, and the inlet side A plurality of second cells having a sealing portion on the bottom surface and opening the bottom surface on the outlet side are provided, and the plurality of first cells and the plurality of second cells are alternately arranged adjacent to each other with a porous partition wall in between. A columnar honeycomb structure filter having an average film thickness T (unit: μm) of 2 to 50 μm and a porosity P (unit:%) of 65 to 90% on the surface of each first cell, and an average film. A columnar honeycomb structure filter on which a ceramic porous film satisfying the relational expression of thickness T and porosity P of 0.36T + 60≤P≤0.75T + 72 is formed.
