Title:
DIELECTRIC DRYING METHOD OF HONEYCOMB STRUCTURE
Document Type and Number:
Japanese Patent JP2637651
Kind Code:
B2
Abstract:
PURPOSE: To provide a method capable of preventing honeycomb structure from self-heat release, ignition and cracking, also capable of reducing its dimensional variations, etc., due to the use of a continuous drying oven.
CONSTITUTION: A honeycomb structure 2 is put on a drying table 3 which is a perforated table as to be higher in electrical conductivity for a specified region containing a portion coming into contact with the opening lower end surface of the honeycomb structure 2 than the other outer peripheral portion, and an electric current is applied between electrodes provided respectively at above the upper end surface and below the lower end surface of the structure 2, thus carrying out the objective dielectric drying. In this process, the electrodes 15-1a to 15-1c and 15-2a to 15-2c are respectively plurally divided at the vertically corresponding positions, and the honeycomb structure is intermittently moved in every pair of electrode unit 15-1a and 15-2a, 15-1b and 15-2b, and 15-1c and 15-2c.
