Abstract
A method for manufacturing a honeycomb structure includes molding a ceramic raw material to manufacture at least one honeycomb molded body having a plurality of cell walls extending along a longitudinal direction of the at least one honeycomb molded body to define cells. The honeycomb molded body is fired to manufacture a honeycomb fired body. A honeycomb block is manufactured by using the honeycomb fired body. The honeycomb fired body is cut before manufacturing the honeycomb block or the honeycomb block is cut after manufacturing the honeycomb block.
Claims46
A method for manufacturing a honeycomb structure, comprising:
- molding a ceramic raw material to manufacture a plurality of honeycomb molded bodies each having a plurality of cell walls extending along a longitudinal direction thereof to define cells;
- firing said plurality of honeycomb molded bodies to manufacture a plurality of honeycomb fired bodies;
- connecting said plurality of honeycomb fired bodies to each other with an adhesive paste provided between the plurality of honeycomb fired bodies to manufacture a honeycomb block;
- cutting the honeycomb block after manufacturing the honeycomb block into two pieces having a substantially equal longitudinal length;
- and
- providing a plug material paste in the cells at either one end of each of the cells after cutting.
A method for manufacturing a honeycomb structure, comprising:
- molding a ceramic raw material to manufacture at least one honeycomb molded body having a plurality of cell walls extending along a longitudinal direction of the at least one honeycomb molded body to define cells;
- providing a first plug material paste in the cells at either one end of each of the cells to seal cells;
- firing said at least one honeycomb molded body with the plug material paste to manufacture at least one honeycomb fired body;
- manufacturing a honeycomb block by using said at least one honeycomb fired body;
- cutting each of the at least one honeycomb fired body into cut honeycomb fired bodies having cut end so that a longitudinal length of the cut honeycomb fired body is shorter than a longitudinal length of the honeycomb fired body before the cutting;
- providing a second plug material paste in the cells at the cut end to seal the respective cells at either one end in the longitudinal direction;
- and
- firing said second plug material paste.
