Problems solved by technology

[0006] In dielectric drying, the density of the electric force lines passing through the formed honeycomb body tends to become non-uniform, thereby sometimes causing partial drying delays on the formed honeycomb body, resulting in dimensional variations in the obtained honeycomb structure, Cracks and other issues

Abstract

The present invention relates to a method of drying honeycomb formed bodies. More specifically, the present invention relates to a method of drying honeycomb formed bodies with which they cannot easily be affected by an atmosphere in a dry space and can be dried without occurrence of deformation and cracks of outer peripheries thereof even when partition walls thereof are thin. The method of drying a ceramic formed body comprising the step of performing dielectric drying on an unfired honeycomb formed body formed with a ceramic material as a main raw material under a condition that a power density is 5 to 20 [kW / kg (water)].

Description

technical field [0001] The present invention relates to a method for drying a formed honeycomb body. More specifically, it relates to a method for drying a formed honeycomb body that is less affected by the atmosphere in the drying space even when the partition walls are thin, and can be dried without deformation or cracks in the outer periphery. Background technique [0002] Honeycomb structures made of ceramics are widely used for catalyst supports, various filters, and the like. Recently, attention has been drawn to a diesel particulate filter (DPF) for capturing particulate matter (particulate matter) discharged from a diesel engine. [0003] In general, such a honeycomb structure can be obtained by adding forming aids and various additives to a dispersion medium such as a ceramic material and water to obtain a raw material composition, kneading the raw material composition, and forming a billet After soiling, extrusion molding is performed to produce a honeycomb-shape...
