Glass-welded plane double-vacuum-layer glass having installing holes at edge sealed by sealing strips

Abstract

The invention relates to a glass-welded plane double-vacuum-layer glass having installing holes at edge sealed by sealing strips, which comprises an upper glass, a lower glass and an intermediate glass, the installing holes are provided, 1-4 installing holes are provided, at least a sealing strip is respectively provided at lower surface circumference of the upper glass and the intermediate glass and the circumference of the installing hole, at least two sealing strips are provided at upper surface circumference of the intermediate glass and the lower glass, at least a sealing strip is arranged at the lower glass corresponding to the installing hole, three glasses are rapidly heated, and the circumference can be welded together by pressurizing through a glass solder in a 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, large-batch production of toughened vacuum glass is realized, and usage life is increased.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a plane double-vacuum-layer glass with sealing strip edge-sealing glass welded with installation holes 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...
