text: A method (hereinafter sometimes referred to as “first invention”) of manufacturing a plugged honeycomb structure comprising a cylindrical honeycomb structure having porous partition walls and a plurality of cells partitioned by the partition walls and extending through the structure from one end to the other end thereof, and plugging members which plug portions of predetermined cells having a predetermined length from one end of each cell, the opposite ends of the remaining cells being open without being plugged, the method comprising the steps of: forming a clay including a forming material into a honeycomb shape to obtain a cylindrical honeycomb formed body having a plurality of partitioned cells extending through the formed body from one end to the other end thereof; preparing a plugging material of the plugging members so that a contraction ratio (firing contraction ratio) of the plugging material during the firing is a predetermined ratio with respect to the firing contraction ratio of the honeycomb formed body; plugging openings of the predetermined cells of the resultant honeycomb formed body on one end side with the plugging material to obtain a plugged honeycomb formed body; and firing the resultant plugged honeycomb formed body in a state in which the plugged honeycomb formed body is laid on a firing setter so as to bring each end plugged with the plugging material into contact with the firing setter to thereby obtain the plugged honeycomb structure.
text: A method (hereinafter sometimes referred to as “second invention”) of manufacturing a plugged honeycomb structure comprising a cylindrical honeycomb structure having porous partition walls and a plurality of cells partitioned by the partition walls and extending through the structure from one end to the other end thereof, and plugging members which plug portions of predetermined cells having a predetermined length from one end of each cell, the opposite ends of the remaining cells being open without being plugged, the method comprising the steps of: forming a clay including a forming material into a honeycomb shape to obtain a cylindrical honeycomb formed body having a plurality of partitioned cells extending through the formed body from one end to the other end thereof; firing the resultant honeycomb formed body to obtain the honeycomb structure; preparing a plugging material of the plugging members so that a contraction ratio (firing contraction ratio) of the plugging material during the firing is a predetermined ratio with respect to the firing contraction ratio of the honeycomb structure; plugging openings of the predetermined cells of the resultant honeycomb structure on one end side with the plugging material to obtain a plugged honeycomb precursor; and firing the resultant plugged honeycomb precursor in a state in which the plugged honeycomb precursor is laid on a firing setter so as to bring each end plugged with the plugging material into contact with the firing setter to thereby obtain the plugged honeycomb structure.
text: A plugged honeycomb structure (hereinafter sometimes referred to as the third invention) comprising: a cylindrical honeycomb structure having porous partition walls and a plurality of partitioned cells extending through the structure from one end to the other end thereof; and plugging members which plug portions of predetermined cells having a predetermined length from one end of each cell, the opposite ends of the remaining cells being open without being plugged, the plugged honeycomb structure being constituted so that a ratio (length/outer diameter) of a length of the honeycomb structure in an axial direction with respect to the outer diameter of the cylindrical honeycomb structure is in a range of 0.1 to 0.8.
text: In this manner, the plugged honeycomb structure can be manufactured which is provided with: the cylindrical honeycomb structure having the porous partition walls and a plurality of cells partitioned by the partition walls and extending through the structure from one end to the other end thereof; and the plugging members which plug the portions (end portions) of the predetermined cells having the predetermined length from one end of each cell, the opposite ends of the remaining cells being opened without being plugged.
