20090239744 | HONEYCOMB STRUCTURE AND METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE - A honeycomb structure includes a plurality of honeycomb fired bodies combined with one another. The honeycomb fired bodies include a center-portion honeycomb fired body located in a center portion in a cross section perpendicular to a longitudinal direction and a peripheral-portion honeycomb fired body located in a peripheral portion in the cross section. The center-portion honeycomb fired body has a substantially rectangular cross-sectional shape and has an area from about 2500 mm | 09-24-2009 |
20090246097 | HONEYCOMB STRUCTURE AND EXHAUST GAS TREATING APPARATUS - A honeycomb structure includes four honeycomb units each including inorganic particles, an inorganic binder, and cell walls extending from a first end face to a second end face along a longitudinal direction to define a plurality of cells. The cell walls includes a first cell walls extending along a first direction in a cross sectional plane perpendicular to the longitudinal direction and a second cell walls extending along a second direction substantially perpendicular to the first direction in the cross sectional plane. Adhesive layers are provided between the four honeycomb units to connect the four honeycomb units. The adhesive layers extend in a first extending direction and a second extending direction substantially perpendicular to the first extending direction in the cross sectional plane. A minimum angle between the first direction and the first extending direction or the second extending direction is approximately 22.5 degrees to approximately 45 degrees. | 10-01-2009 |
20110113614 | METHOD FOR MANUFACTURING HONEYCOMB STRUCTURAL BODY AND METHOD FOR MANUFACTURING EXHAUST GAS CONVERTING APPARATUS - A method for manufacturing a honeycomb structural body having a honeycomb unit includes obtaining a honeycomb molded body including a compound containing a phosphate group zeolite and an inorganic binder. The honeycomb molded body has a plurality of through holes that are defined by cell walls and arranged in a longitudinal direction of the honeycomb molded body. The honeycomb molded body is dried. The dried honeycomb molded body is fired to obtain the honeycomb unit. At least one of the honeycomb unit and the dried honeycomb molded body is stored so that a difference in moisture content is approximately 5 mass % or less between a moisture content of the cell walls at a center part of a cross section perpendicular to the longitudinal direction and a moisture content of the cell walls at an outer periphery part of the cross section perpendicular to the longitudinal direction. | 05-19-2011 |
20110116988 | HONEYCOMB STRUCTURAL BODY AND EXHAUST GAS CONVERTING APPARATUS - A honeycomb structural body includes a honeycomb unit having a plurality of through holes defined by cell walls and arranged in a longitudinal direction of the honeycomb unit. The honeycomb unit includes an inorganic binder, a first zeolite, and second zeolite. The first zeolite includes at least one of a β type zeolite and a ZSM-5 type zeolite, and primary particles having an average particle diameter of approximately 0.01 μm or more and approximately 0.1 μm or less. The second zeolite includes a phosphate group zeolite and primary particles having an average particle diameter of approximately 0.5 μm or more and approximately 5 μm or less. A ratio between a mass of the first zeolite and a total mass of the first and second zeolites is approximately 0.1 or more and approximately 0.5 or less. | 05-19-2011 |
20110118106 | HONEYCOMB STRUCTURE - A honeycomb structure includes a honeycomb unit. The honeycomb unit includes plural cells, inorganic particles, and at least one of a flake substance, a tetrapod-shaped substance, and a three-dimensional needle-shaped substance. The plural cells extend from a first end face to a second end face of the honeycomb structure along a longitudinal direction of the honeycomb structure. The plural cells are defined by cell walls. | 05-19-2011 |
20120080828 | METHOD OF MANUFACTURING HONEYCOMB STRUCTURE - A method of manufacturing a honeycomb structure including a honeycomb unit includes causing inorganic particles to contain water. The inorganic particles have a specific surface area of approximately 50 m | 04-05-2012 |
20120251400 | HONEYCOMB STRUCTURAL BODY AND EXHAUST GAS CONVERSION APPARATUS - A honeycomb structural body includes at least one honeycomb unit including a β type zeolite, a phosphate group zeolite, and an inorganic binder and having a plurality of through holes divided by partition walls and arranged in a longitudinal direction of the honeycomb unit. The β type zeolite includes secondary particles having an average particle diameter of approximately 0.5 μm or more and approximately 5 μm or less. The phosphate group zeolite includes primary particles having an average particle diameter of approximately 0.5 μm or more and approximately 5 μm or less. A ratio of a mass of the phosphate group zeolite with respect to a total mass of the β type zeolite and the phosphate group zeolite is approximately 5% or more and approximately 35% or less. | 10-04-2012 |
