Production process of a hexagonal honeycomb structure |
摘要 |
The present invention provides a production process of a hexagonal honeycomb structure having low deformation of hexagonal cells. This process comprises an extrusion step for obtaining moldings (7) in which partitions (71) are provided in the form of a hexagonal matrix by extrusion molding of a mixed raw material using a horizontal extruder having an extrusion die provided with slits in the form of a hexagonal matrix and in which the direction of extruding is substantially the horizontal direction, a drying step for drying moldings (7), and a baking step for baking moldings (7). The extrusion step is performed such that c axis (700) parallel to two parallel sides (702) and (705) of the six sides (701) through (706) of each hexagon formed by partitions (71) of extruded moldings (7) is substantially vertical relative to the horizontal plane.
