POROUS HONEYCOMB FILTER |
摘要 |
There is disclosed a porous honeycomb filter whose trapping efficiency does not drop even when a porosity fluctuates and which is capable of balancing the trapping efficiency and a pressure loss. The porous honeycomb filter is a filter whose pore distribution has been controlled. A volume of pores having a pore diameter of 15 µm or less is 0.07 cc/cc or less, and a volume of pores having a pore diameter of 40 µm or more is 0.07 cc/cc or less.
