Method for forming a vent port in a glass panel, and glass panel product manufactured using same

Abstract

The present invention relates to a method for forming a vent port in a glass panel and to a glass panel product manufactured using same. The present invention relates to a method for forming a vent port in a glass panel having no protruding vent pipe, such that the vent port for discharging gas from a sealed space to the outside is formed in either one of a pair of plate glasses which are spaced apart from each other in a thickness direction to form the sealed space therebetween, wherein the method comprises the following steps: forming a vent hole in either one of the plate glasses; vertically inserting a vent-pipe-type sealing member into the upper portion of the exhaust hole; discharging gas between the plate glasses to the outside; heating the sealing member such that the sealing member is converted into a fluid state, and the vent hole is closed by the sealing member having collapsed after being heated; and solidifying the sealing member remaining in the vent hole, thereby ensuring superior sealing properties without using a protruding vent pipe.

Description

technical field [0001] The invention relates to a glass panel (such as vacuum multi-layer glass, plasma display panel, etc.) formed to decompress (or inflate) the space between a pair of flat glasses. A technique to depressurize the exhaust port and seal the exhaust port after decompression. Background technique [0002] Conventionally, one of a pair of plate glasses arranged at intervals along the thickness direction is provided with an exhaust port for exhausting gas in a closed space between the two plate glasses to the outside. In this case, an exhaust hole is provided on the above-mentioned one plate glass, and an exhaust pipe is vertically arranged on the above-mentioned exhaust hole. [0003] At the same time, the sealing molding material is heated and melted after the sealing molding material is interposed between the lower end portion of the exhaust pipe and the upper periphery of the above-mentioned exhaust hole on the one plate glass, so that the above-mentioned ...

AI Technical Summary

Problems solved by technology

At this time, the sealing portion 19 is formed to seal the interface between the exhaust pipe 7 of the protruding exhaust port and the upper plate glass 18, but since the sealing molding material is heated and melted to a temperature above the softening point of the plate glass, there are Problems causing damage to the upper plate glass 18

[0022] In order to solve the above problems, it is necessary to form an exhaust port for decompressing the space between the flat glass at the minimum height possible when manufacturing the glass panel. Efficient way to seal the vent, but still no significant results
