Title:
目封止ハニカム構造体の製造方法
Document Type and Number:
Japanese Patent JP5612588
Kind Code:
B2
Abstract:
A method for manufacturing a plugged honeycomb structure includes: a step of forming a columnar honeycomb formed body, and a plugging step of forming plugging portions in each of cells of the honeycomb formed body; wherein the plugging step has a plugging slurry injection operation where plugging slurry is injected into the cells by inserting the honeycomb formed body into a bottomed cylindrical inside container containing the plugging slurry and having a Young's modulus of 5 to 550 MPa and a tensile stress of 0.5 to 11 MPa and being disposed in a bottomed cylindrical outside container and by pressing one end portion against the bottom face of the inside container, and then the honeycomb formed body is pulled out from the inside container. There is provided a method for manufacturing a plugged honeycomb structure, the method being capable of inhibiting depression and protrusion of plugging portions.
