Glass-welded plain double-vacuum-layer glass provided with edges sealed by sealing grooves and provided with mounting hole(s)

Abstract

Glass-welded plain double-vacuum-layer glass provided with edges sealed by sealing grooves and provided with mounting hole(s) is disclosed. The plain double-vacuum-layer glass comprises upper glass, lower glass and middle glass, and is characterized in that: the plain double-vacuum-layer glass is provided with the mounting hole(s); the lower surfaces of the upper glass and the middle glass and the periphery of each mounting hole are provided with sealing strips; corresponding positions of the peripheries of the upper surfaces of the middle glass and the lower glass and each mounting hole are provided with the sealing grooves; after being rapidly heated, the upper glass and the middle glass as well as the lower glass and the middle glass are subjected to sheet combining at a high temperature, and the peripheries of the upper glass, the middle glass and the lower glass and the periphery of each mounting hole are welded under elevated pressure by glass solder in a vacuum furnace; and two sealed vacuum layers are formed among the upper glass, the lower glass and the middle glass. The vacuum glass and a manufacturing method thereof are simple in process and high in production efficiency. The manufactured tempered vacuum glass eliminates edge sealing stress and maintains tempered characteristics of tempered glass. The 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 plane double-vacuum-layer glass with sealing groove 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 fo...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a flat double-vacuum laminated glass with sealing groove and edge sealing glass welded with installation holes and its manufacturing method in view of the defects existing in the existing vacuum glass, and the vacuum glass and its manufacturing method Simple, high production efficiency, the prepared tempered vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered characteristics of tempered glass, can produce tempered vacuum glass in large quantities, and can increase its service life
