Abstract: front page image
(EN)This honeycomb filter is provided with a ceramic honeycomb substrate comprising a porous body containing sintered ceramic particles, and a filtration layer formed on cell wall surfaces. The honeycomb filter is characterized in that: part of the filtration layer penetrates pores constituted by the ceramic particles from the cell wall surfaces, and forms an inter-particle filtration body; and the inter-particle filtration body comprises multiple spherical ceramic particles and a crosslinking body that binds the spherical ceramic particles, and the spherical ceramic particles and the crosslinking body are configured in a three-dimensional network structure.
(FR)L'invention concerne un filtre en nid d'abeilles qui comprend un substrat céramique en nid d'abeilles comprenant un corps poreux contenant des particules céramiques frittées, et une couche de filtration formée sur les surfaces des parois cellulaires. Le filtre en nid d'abeilles est caractérisé en ce que : une partie de la couche de filtration pénètre dans des pores constitués par les particules céramiques des surfaces des parois cellulaires, et forme un corps de filtration inter-particulaire ; et le corps de filtration inter-particulaire comprend plusieurs particules céramiques sphériques et un corps de réticulation qui relie les particules céramiques sphériques, et les particules céramiques sphériques et le corps de réticulation sont configurés sous la forme d'une structure de réseau tridimensionnelle.
