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

Abstract

Glass-welded plain double-vacuum-layer glass provided with edges sealed by sealing grooves and sealing strips 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: each mounting hole and a corresponding air extracting hole are of an integrated structure; the number of the mounting hole(s) is 1-4; the lower surfaces of the upper glass and the middle glass and the periphery of each air extracting 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 air extracting hole are provided with the sealing grooves and sealing strips; after the three sheets of glass are rapidly heated, peripheries of the three sheets of glass are welded under elevated pressure by glass solder in a heating furnace; each air extracting hole is sealed on line by utilization of melted glass in a continuous vacuum furnace; and two sealed vacuum layers are formed among the three sheets of 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 mounting holes on the edge sealing of glass welding sealing strip grooves 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 kep...
