Method for manufacturing honeycomb structral body and method for manufacturing exhaust gas converting apparatus

摘要

A method for manufacturing a honeycomb structural body according to the present invention manufactures a honeycomb structural body including a honeycomb unit by including the steps of: obtaining a honeycomb molded body having a compound containing a phosphate group zeolite and an inorganic binder and having a plurality of through holes divided by cell walls and arranged in a longitudinal direction thereof; drying the honeycomb molded body; obtaining the honeycomb unit by firing the dried honeycomb molded body; and storing the dried honeycomb molded body and/or the honeycomb unit so that the difference between a moisture content of the cell walls at a center part of a cross section perpendicular to the longitudinal direction and a moisture content of the cell walls at an outer periphery part of the cross section perpendicular to the longitudinal direction is 5 mass% or less.
