PREPARATION METHOD OF CERAMIC MONOLITH STRUCTURE AND CERAMIC MONOLITH STRUCTURE THEREBY

摘要

The present invention relates to a method of manufacturing a ceramic monolith structure having a plurality of cells to form a passage of a fluid using a thin flat ceramic plate and a thin wave-shaped ceramic plate. The method includes the steps of: obtaining plastic clay by making paste of a molding source material including a ceramic source material and a plastic aid; forming the thin flat ceramic plate using the plastic clay, which has been obtained in the paste making process, through an extruder; making the thin wave-shaped plate having a furrow by putting the flat plate, which has been obtained in the flat ceramic plate forming process, between two rollers having grooves in order to form the fluid passage; cutting the thin flat and wave-shaped plates to a predetermined size and alternately stacking the plates to form a rectangular monolith structure, or rolling one thin flat plate and one thin wave-shaped plate to manufacture a cylindrical monolith structure; and drying and baking the manufactured monolith structure. According to the method of manufacturing the ceramic monolith structure, an extruder having a complex structure is not used, so the difficulty of manufacturing the extruder can be overcome, and the ceramic monolith structure having various sizes and various shapes can be easily manufactured. Accordingly, the size of the fluid passage can be easily controlled.
