Definitions
- SAE paper 860,008 in 1986 discloses a ceramic honeycomb structure in which cordierite honeycomb segments are similarly bonded with cordierite cement.
- Japanese Patent Application Laid-Open No. Hei 8-282246 discloses that a honeycomb ceramic member is bonded with an elastic sealing material composed of inorganic fibers, an inorganic binder, an organic binder, and inorganic particles intersecting at least three-dimensionally.
- a ceramic honeycomb structure is disclosed.
- FIG. 9 is a graph showing the results of the combustion regeneration test. BEST MODE FOR CARRYING OUT THE INVENTION
- the cross section means a cross section perpendicular to the direction of the flow hole unless otherwise specified.
- the 82-cam structure may be loaded with a metal having the above-mentioned catalytic ability in order to promote the combustion.
- each of the honeycomb structure fillers (Example 1) and Comparative Examples 1 to 3 (honeycomb structure assembly) thus obtained contained particles (hereinafter referred to as “strips”) discharged from the diesel engine, respectively.
- strips particles
- 0 g is collected, the soot deposited on the filter is burned by exhaust gas with an inlet gas temperature of 700 ° C, an oxygen concentration of 10%, and an exhaust gas flow rate of 0.7 Nm 3 min., And the temperature of the honeycomb structure at 15 points was measured.
- the weight of the honeycomb structure filter was measured to determine the soot regeneration efficiency. Furthermore, damage to the structure due to combustion regeneration was visually observed and observed with a stereoscopic microscope, and the presence or absence of damage was confirmed.
