摘要： The invention concerns a process for producing a ceramic honeycomb filter from a porous ceramic honeycomb material comprising a plurality of channels extending through it from one end face to the other end face. The process of the invention comprises at least the following steps consisting of a) providing each end face of the honeycomb material with a perforated film the perforations of which are such that the channels traversing the material are alternately open at one or the other of their end faces so that, for each channel open at one end face, the adjacent channels are closed; and b) introducing, by suction through the perforations of the film applied to each end face, a sealing material into the channels to obtain a ceramic filter the channels of which are not sealed at one of the end faces and are sealed at the other end face.

摘要： The present invention relates to a method for impregnating a porous body (14) by a suspension (12) containing at least partly particles, said body comprising a multiplicity of channels (16) delimited by porous walls (22) extending from one (18) of the faces to the other (20) face of said body, part of said channels being obstructed at one face and the other part of the channels being obstructed at the other face.According to the invention, the method consists in: making a suspension whose particle size distribution meets a DV90/Dpores ratio below 0.25 and whose viscosity is such that said suspension is brought inside the walls while depositing part of the particles on the surface of the pores of the walls, communicating one (18, 20) of the faces of body (14) with an enclosure (30) containing the suspension, feeding the suspension into the body, exerting a force on the suspension introduced so that said suspension flows through the walls, passing a fluid through the walls.
