METHOD OF MAKING MEMBRANE FILTER |
摘要 |
<p>Wall flow membrane filters, fabricated by masking a first subset of the channels at one or both ends of a honeycomb body comprising an array of open-ended through-channels separated by porous channel walls, applying a membrane-forming composition to the porous channel walls of a second subset of the channels, curing the membrane-forming composition to provide a wall-adhering fluid-permeable membrane; and then plugging the first subset of channels at a first end of the body and the second subset of channels at a second end of the body, are useful in exhaust systems of improved particulate filtration efficiency for gasoline direct injection or diesel engines.</p> |
