EXHAUST GAS CLEANING FILTER MEDIUM AND METHOD OF MANUFACTURING THE SAME. |
摘要 |
To provide a filter medium for an automobile exhaust gas which has a high capability of collecting solid and liquid components of an exhaust gas and a sufficiently high resistance to the combustion cleaning heat, and a method of manufacturing the same. A three-dimensional reticulated metallic porous material of Ni-Cr-Al with fibrous crystals of alumina densely set on the surface of its three-dimensional skeleton is heated to 800 DEG -1000 DEG C in the atmospheric air, and the resultant material is used as a filter medium. Accordingly, the filter medium has excellent filtration performance and corrosion resistance, and withstands a high temperature. This filter medium is capable of firmly supporting a catalyst on the fibrous crystals of alumina constituting the surface of the filter medium. The increased surface area can support an increased amount of catalyst. <IMAGE> |
