VACUUM SEALING METHOD OF A VACUUM CONTAINER WITHOUT FORMING A SEPARATE VACUUM EXHAUST PIPE WITHIN THE VACUUM CONTAINER

摘要

PURPOSE: A vacuum sealing method of a vacuum container prevents the out-gassing of organic components generated during firing of glass frit paste by manufacturing a solid only with inorganic glass frit to seal the vacuum container.;CONSTITUTION: A solid with multiple air gaps is manufactured by heating glass frit powder at a first temperature, after loading the glass frit powder into a mold to manufacture the solid in the shape corresponding to an opening of a vacuum container (S10). Vacuum exhaust is performed within the vacuum container through the air gaps after inserting the solid into the opening of the vacuum container (S20). The vacuum container is sealed by heating the solid at a second temperature higher than the first temperature (S30).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Glass frit powder is loaded into a mold with a shape of an opening of a vacuum container; (BB) Solid with multiple air gaps is manufactured by heating glass frit powder at a first temperature; (CC) Solid is inserted to the opening of the vacuum container; (DD) Vacuum drawing process is performed based on the multiple air gaps of the solid; (S30) Vacuum container is sealed by heating the solid at a second temperature
