摘要:
A method for manufacturing a honeycomb structured body according to the present invention comprises manufacturing a pillar-shaped honeycomb molded body having a large number of cells longitudinally placed in parallel with one another with a cell wall therebetween; forming a honeycomb fired body by degreasing and firing the honeycomb molded body; and binding a plurality of the honeycomb fired bodies by interposing a sealing material layer, and further comprising: drawing information on a side face of the honeycomb molded body and/or the honeycomb fired body, prior to said binding, said information drawn in form of at least one of a graphic, a symbol, a character, a barcode and a two-dimensional code.
摘要:
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.

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.
摘要:
A ceramic filter assembly having improved exhaust gas processing efficiency. The ceramic filter assembly (9) is produced by adhering with a ceramic seal layer (15) outer surfaces of a plurality of filters (F1), each of which is formed from a sintered porous ceramic body. The seal layer (15) has a thickness of 0.3 mm to 3 mm and a thermal conductance of 0.1 W/mK to 10 W/mk.

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.

摘要:
A honeycomb structured body of the present invention is a honeycomb structured body in which plural pillar-shaped honeycomb units are bonded to one another through sealing material layers, each unit having in the longitudinal direction a large number of cells placed in parallel with a cell wall therebetween. Herein, a cross-sectional area of the honeycomb unit on a cross-section perpendicular to the length direction is at least about 5 cm2 and at most about 50 cm2, the honeycomb unit includes inorganic fibers and/or whiskers in addition to inorganic particles, and a Young's modulus of the honeycomb unit is at least about 50% and at most about 150% of a Young's modulus of the sealing material layer.
