Metal-welded plain vacuum glass with installing holes and edge sealed by sealing strips

Abstract

The invention relates to a metal-welded plain vacuum glass with installing holes and edge sealed by sealing strips, which comprises an upper glass and a lower glass, the installing holes and extraction openings are combined as an integral body, 1-4 installing holes are arranged, at least a sealing strip is provided at circumference of the upper glass and the extraction opening, at least two sealing strips are provided at circumference of the lower glass and the extraction opening, the sealing strip of the upper glass is inserted between the sealing strips of the lower glass; the upper glass and the lower glass are rapidly heated and laminated at high temperature, the circumference can be welded together by pressurizing through an alloy solder in an atmosphere heating furnace, and the extraction opening is enclosed by using metal solder in vacuum furnace. The vacuum glass and its production method have the advantages that the process is simple and the production efficiency is high, the prepared vacuum glass can eliminate the stress of the sealed edge and can keep the toughening characteristic of the toughened glass, so that toughened vacuum glass can be massively produced, and its usage life is increased.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat vacuum glass with a metal welding sealing strip edge sealing and an installation hole and a manufacturing method thereof. Background technique [0002] As a new type of glass with the most energy-saving potential, vacuum glass has achieved large-scale production after more than ten years of research and development, and has been well applied in many fields, especially in the construction field; but there are also obvious The shortcomings are mainly low production efficiency, small production capacity, and inability to produce tempered vacuum glass, etc., which limit its popularization and application in a wider range; the existing large-scale production of vacuum glass uses high temperature (430-480°C) normal pressure The production process of lower edge sealing, low temperature (180-300°C) vacuuming and sealing, because it needs to be kept warm for a period ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a flat vacuum glass with mounting holes on the edges sealed with metal welding sealing strips and its manufacturing method for the defects of the existing vacuum glass. This vacuum glass and its manufacturing method are simple in process, The production efficiency is high. The prepared tempered vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered characteristics of the tempered glass. It can produce tempered vacuum glass in large quantities and increase its service life.
