METHOD FOR PRODUCING HONEYCOMB FILTER AND METHOD FOR PRODUCING CERAMIC FILTER ASSEMBLY

摘要

A method for producing a honeycomb filter includes mixing ceramic particles and a binder to obtain a ceramic raw material slurry. The ceramic raw material slurry is provided into an extruder to obtain a molded honeycomb filter. The molded honeycomb filter includes cell walls extending along a longitudinal direction of the molded honeycomb filter to define cells having a substantially square shape. The molded honeycomb filter is dried using a microwave dryer. A sealing paste is provided in at least one of the cells at one end face of the honeycomb filter to seal the at least one of the cells at the one end face. The sealing paste is dried using a microwave dryer. The dried molded honeycomb filter is sintered.
