摘要:
A method of applying a cement mixture to an exposed matrix of intersecting walls of a honeycomb body is disclosed. The method may include the steps of providing an applicator, feeding the cement mixture into applicator, forcing the cement mixture to exit the applicator with a substantially uniform velocity, while depositing the cement mixture on the exposed matrix of the honeycomb body.

摘要:
Disclosed are plugging mixtures for forming a ceramic honeycomb wall flow filter. The plugging mixtures exhibit a reduced percentage of volumetric shrinkage during the drying process and generally comprise an inorganic ceramic powder batch composition; an organic binder; a liquid vehicle; and a non-foaming volume transformation agent. Also disclosed are methods for forming plugged ceramic wall flow filters from such plugging mixtures and honeycomb articles produced therefrom.
