Title:
METHOD FOR PRODUCING SEALING HONEYCOMB STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/040402
Kind Code:
A1
Abstract:
Provided is a method for producing a sealing honeycomb structure comprising a step for forming a columnar honeycomb molding having partition walls forming a plurality of cells extending from one end to the other end and defining flowing passages of a fluid, and a sealing step for forming a sealing portion at an end of the cells of the honeycomb molding, wherein the sealing step comprises a sealing slurry press fitting operation for inserting the honeycomb molding in an closed-end inner container, which has sealing slurry stored therein and is disposed in a closed-end cylindrical outer container, while pressing an end of the honeycomb molding onto a bottom surface of the inner container so as to press fit the sealing slurry into the cells, and thereafter, removing the honeycomb molding from the inner container, the inner container having a Young's modulus of 5 to 550 MPa and a tensile stress of 0.5 to 11 MPa. According to the method for producing a sealing honeycomb structure, a recess or projection at the sealing portion can be prevented.
