Facets:
Source sentences:
text: When the porosity of the partition wall is less than 20%, when loading a catalyst onto the honeycomb structure, the catalyst is difficult to infiltrate into pores of the partition wall, and the catalyst tends to load only onto the surface of the partition wall of the honeycomb structure.
text: The reason is that if the porosity of this honeycomb unit is less than 20%, the pressure loss in the filter can be high.
text: When the porosity is less than 20%, the integrated honeycomb structural body 20 is more susceptible to clogging, while the porosity exceeding 80% causes degradation in the strength of the integrated honeycomb structural body 20, with the result that it can be easily broken.
