APPARATUS AND METHOD FOR QUANTITATIVELY COATING CATALYST SUPPORT

摘要

The present invention provides a quantitative coating method of a catalyst support for quantitatively coating a catalyst slurry to be applied to exhaust gas post-processing to a monolithic catalyst support having a plurality of channels longitudinally formed, comprising the following steps: injecting the catalyst slurry into a measuring container of which the bottom moves up and down; moving the catalyst support to the upper portion of the container so as to allow the lower end of the catalyst support and the upper end of the container to be horizontal; sealing the lower end of the catalyst support and the upper end of the container from the outside; moving up the bottom of the container; and applying a vacuum.
