Glass-welded plain vacuum glass with edges sealed by sealing grooves and manufacturing method thereof

Abstract

Glass-welded plain vacuum glass with edges sealed by sealing grooves is disclosed. The plain vacuum glass comprises upper glass and lower glass, and is characterized in that: the upper glass is provided with sealing strips; the periphery of the lower glass is provided with the sealing grooves; after being rapidly heated, the upper glass and the lower glass are subjected to sheet combining at a high temperature, and the peripheries of the upper glass and the lower glass are welded under elevated pressure by glass solder in a vacuum furnace; a sealed vacuum layer is formed between the upper glass and the lower glass; and supports arranged in a point array are disposed in the vacuum layer. The vacuum glass and a manufacturing method thereof are simple in process and high in production efficiency. The manufactured vacuum glass eliminates edge sealing stress and maintains tempered characteristics of tempered glass. Tempered vacuum glass can be produced in a large scale, and the service lifetime of the tempered vacuum glass can be prolonged.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat vacuum glass welded with sealing groove edge sealing glass 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 of time at the edge sealing...

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 welded with sealing groove edge sealing glass and its manufacturing method in view of the defects existing in the existing vacuum glass. This vacuum glass and its manufacturing method are simple in process and high in production efficiency , the prepared vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered properties of tempered glass, which can be mass-produced tempered vacuum glass and can increase its service life
