Mold for Ceramic Membrane Tube and Fabrication Method of Ceramic Membrane Tube Using the Same

A fabrication method of a one-end closed ceramic membrane tube comprising:

• attaching a cap, which has a through hole at the center thereof, to an end of an extrusion hold of an extrusion mold, the extrusion mold including an outer mold and an inner mold;
• supplying a ceramic membrane mixture into a space between the outer mold and the inner mold of the extrusion mold to perform an extrusion;
• removing the cap when the ceramic membrane mixture is extruded through the through hole;
• and
• obtaining an extrusion body with a particular length by additionally supplying the ceramic membrane mixture into the space between the outer and inner molds of the extrusion mold and then continuously performing the extrusion.

A fabrication method of a one-end closed ceramic membrane tube comprising:

• blocking (closing) an end of an extrusion hold of an extrusion mold by using a cap, the extrusion mold including an outer mold and an inner mold;
• supplying a ceramic membrane mixture into a space between the outer mold and the inner mold of the extrusion mold to perform an extrusion;
• removing the cap when the ceramic membrane mixture is filled in the end of the extrusion hole to create a closed structure;
• obtaining a ceramic extrusion body with a particular length by additionally supplying the ceramic membrane mixture into the space between the outer and inner molds of the extrusion mold and then continuously performing the extrusion;
• and
• coating a ceramic membrane mixture which is the same as or different from the ceramic membrane mixture onto the surface of the extrusion body.
