Encapsulation method for vacuum glass getter

Abstract

The invention relates to an encapsulation method for vacuum glass getter. The method comprises cutting flat-panel glass into pieces, manufacturing a groove, washing, laying supports, laminating the flat-panel glass pieces, putting a suction pipe, sealing edges, welding the suction pipe, putting the obtained glass product into a stove and heating the glass product to above 420 DEG C for fusing theedges and the suction pipe and vacuumizing outside the stove. After the edges of the two glass pieces are sealed and the two glass pieces are taken out from the stove and before the vacuum pumping isconducted, the getter is put in the suction pipe or is put into a suction groove pre-manufactured on the internal surface of the glass from the suction pipe, a vacuum pump is connected, the suction pipe is sealed after vacuum pumping and the getter is activated to finish the manufacturing of the flat-panel vacuum glass. The invention has the advantages that the design is scientific, the innovation is high, the defects caused when the conventional getter is directly heated and the vacuum glass is directly manufactured are changed, the manufacturing level of the vacuum glass is improved, the novel technology for the vacuum glass is exploited and the foundation is laid for the improvement of the cost and the technological level of the vacuum glass.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a packaging method of a vacuum glass getter. Background technique [0002] The sound insulation, heat insulation and thermal insulation properties of flat vacuum glass are much better than ordinary glass or insulating glass, and its application prospect is very broad. At present, the manufacture of flat vacuum glass requires the use of getters. The function of the getters is to absorb the air that participates in the edge-sealing vacuum glass to ensure the degree of vacuum. The existing general process for manufacturing vacuum flat glass is to put a non-evaporable getter into the gap between two adjacent pieces of glass before the glass substrate is put into the furnace, and then go through a high temperature of about 420°C after entering the furnace. Make the low-melting point glass powder melt and seal the edge. We know that the traditional evaporable getter is oxidized and loses ...

Problems solved by technology

[0004] The above four patents only make a fuss about the placement structure of the vacuum glass getter, and cannot solve the impact of high temperature on the getter at all, so they are also fundamentally different from this patent application
