moisture absorption to prevent the white king is welding ceramic materials

摘要

The present invention relates to a method of manufacturing a ceramic backing material for welding, and more particularly, to a method of manufacturing a ceramic backing material for welding, which comprises applying a waterproofing material for preventing moisture absorption of a ceramic backing material to prevent welding defects due to moisture, dust, Ceramic backing materials.For this purpose, the present invention provides a method of manufacturing a ceramic body, comprising the steps of: preparing a ceramic body having a welded surface formed with a bead groove on one side;Applying a waterproofing agent to the surface of the ceramic body;Drying the applied ceramic body at a temperature of 180C for 10 minutes to 30 minutes;And an assembly step of installing aluminum foil on the both sides and the back side of the dried ceramic body except for the welding surface.;
