Abstract
A honeycomb structure including plural cells with holes arranged in a longitudinal direction, a peripheral wall, and a defective portion formed on the peripheral wall that is mended with a mending material that is in a color different from the color of the peripheral wall. Also, a method is provided for manufacturing a honeycomb structure including plural cells with holes arranged in a longitudinal direction and a peripheral wall which method involves mending a defective portion formed on the peripheral wall of the honeycomb structure with a mending material in a color different from the color of the peripheral wall.
Claims65
A honeycomb structure comprising:
- a plurality of cells with holes arranged in a longitudinal direction;
- and
- a peripheral wall surrounding said plurality of cells,
- the peripheral wall is composed of a coating layer dried, solidified, and formed on a peripheral portion of a honeycomb block,
- wherein said peripheral wall has a mended defective portion formed of a mending material that is in a color different from a color of a material of a remaining portion of the peripheral wall and
- the mended portion is dried and formed after mending with a mending material including a material identical to that of the coating layer.
An exhaust gas treating apparatus comprising:
- a honeycomb structure including:
- a plurality of cells with holes arranged in a longitudinal direction;
- and
- a peripheral wall surrounding said plurality of cells,
- the peripheral wall is composed of a coating layer dried, solidified, and formed on a peripheral portion of a honeycomb block,
- wherein said peripheral wall has a mended defective portion formed of a mending material that is in a color different from a color of a material of a remaining portion of the peripheral wall and
- the mended portion is dried and formed after mending with a mending material including a material identical to that of the coating layer;
- a supporting sealant member arranged at a periphery of the honeycomb structure;
- and
- a metal container in which the honeycomb structure is accommodated.
A method of manufacturing an exhaust gas treating apparatus, the method comprising:
- forming a honeycomb structure including a plurality of cells with holes arranged in a longitudinal direction and a peripheral wall surrounding the plurality of cells;
- mending a defective portion that is formed on the peripheral wall of the honeycomb structure with a mending material that is in a color different from a color of a material of the peripheral wall;
- forming a supporting sealant member arranged at a periphery of the honeycomb structure;
- and
- accommodating the honeycomb structure within a metal container.
