A HONEYCOMB STRUCTURE COMPRISING AN OUTER CEMENT SKIN AND A CEMENT THEREFOR |
摘要 |
Disclosed is a honeycomb catalyst support structure comprising a honeycomb body and an outer layer or skin formed of a cement comprising an amorphous glass powder with a multimodal particle size distribution applied to an exterior surface of the honeycomb body. The multimodal particle size distribution is achieved through the use of a first glass powder having a first median particle size and at least a second glass powder having a second median particle size. In some embodiments, the first and second glass powders are the same amorphous glass consisting of fused silica. The cement may further include a fine-grained, sub-micron sized silica in the form of colloidal silica. The cement exhibits a coefficient of thermal expansion less than 15x10-7/° C, and preferably about 5x10-7/° C after drying. |
