Abstract:
A method for producing a honeycomb filter includes mixing ceramic particles and a binder to obtain a ceramic raw material slurry. The ceramic raw material slurry is provided into an extruder to obtain a molded honeycomb filter. The molded honeycomb filter includes cell walls extending along a longitudinal direction of the molded honeycomb filter to define cells having a substantially square shape. The molded honeycomb filter is dried using a microwave dryer. A sealing paste is provided in at least one of the cells at one end face of the honeycomb filter to seal the at least one of the cells at the one end face. The sealing paste is dried using a microwave dryer. The dried molded honeycomb filter is sintered.
Abstract:
The method for manufacturing a honeycomb structure includes preparing a material composition containing at least a silicon carbide powder, a binder and an additive; molding the material composition to form a pillar-shaped honeycomb molded body in which a number of cells are placed in parallel with one another in a longitudinal direction with a cell wall therebetween; carrying out a degreasing treatment on the honeycomb molded body; and carrying out a firing treatment on the honeycomb degreased body to manufacture a honeycomb fired body. The additive contains at least one kind selected from the group consisting of alumina, silica, titania, zirconia, magnesia, and a chemical composite containing any of alumina, silica, titania, zirconia and magnesia.
Abstract:
A honeycomb filter includes an outer wall having a substantially cylindrical shape and a central axis of the substantially cylindrical shape, first walls provided at an inner side of the outer wall and extending along the central axis, and second walls provided at the inner side of the outer wall and extending along the central axis. The first walls and the second walls substantially perpendicularly cross to define cells having a substantially square shape in a cross-section perpendicular to the central axis. A thickness of the outer wall in the cross-section at a first intersection between the outer wall and a first diameter substantially parallel to the first walls in the cross-section and a thickness of the outer wall in the cross-section at a second intersection between the outer wall and a second diameter substantially parallel to the second walls in the cross-section are largest.
Abstract:
A method for inspecting a honeycomb fired body includes transporting the honeycomb fired body along a transportation line, and inspecting the honeycomb fired body for a crack during the transporting step.
Abstract:
An integral honeycomb filter assembly is produced by adhering ceramic seal layer outer surfaces of a plurality of honeycomb filters. Each of the plurality of honeycomb filters has a plurality of cells defined by a cell wall, and purifies fluid including particulates with the cell wall. A ratio L/S between a filter length L in a flow direction of a processed fluid and a filter cross-section S in a direction perpendicular to the flow direction for each honeycomb filter is 0.06 to 0.75 mm/mm2. A ratio L/S between a filter length L in a flow direction of a processed fluid and a filter cross-section S in a direction perpendicular to the flow direction for the integral honeycomb filter assembly is 0.06 to 0.75 mm/mm2.

Abstract:
A honeycomb filter includes cell walls and cells. The cell walls extend along a longitudinal direction of the honeycomb filter to define the cells between the cell walls. The cells have first cells and second cells each having a substantially square shape in a cross-section perpendicular to the longitudinal direction. The first cells are sealed and the second cells are open at one end face of the honeycomb filter. The substantially square shape of the first cells includes a first side whose extended line intersects a second side except for corner portions of the substantially square shape of the second cells. The second side and the extended line of the first side are substantially perpendicular.
