CERAMIC FILTER MANUFACTURING METHOD AND A CERAMIC FILTER MANUFACTURED THEREBY WITH A LIQUID STATE CONVERTED SUBSTANCE LAYER FORMED ON THE CIRCUMFERENCE OF A MOLDING BAR TO FACILITATE THE SEPARATION OF A CARRIER WINDED ON THE MOLDING BAR

摘要

PURPOSE: A ceramic filter manufacturing method and a ceramic filter manufactured thereby are provided to facilitate the separation of a carrier winded on a molding bar through an area caused by the leakage of a liquid state converted substance melted from the molding bar and an area caused by the contraction of a contraction film as a liquid converted substance layer and the contraction film are formed on the outer circumference of the molding bar.;CONSTITUTION: A ceramic filter manufacturing method includes following steps; a step which immerses slurry with ceramic powder into a carrier(100) in a radial structure or a multi pored structure; a step which winds the carrier on a molding bar(200) with a cylinder shape or a faceted cylinder shape in which a liquid converted substance layer(230) is formed on the outer circumference; a step which forms a first mold removal film which is an area formed as a liquid converted substance is melted and flowed out from the molding bar; and a step which separates the carrier from the molding bar using the first mold removal film.;COPYRIGHT KIPO 2013
