Metal-welded convex vacuum glass provided with edges sealed by sealing grooves and sealing strips and provided with mounting hole(s)

Abstract

Metal-welded convex vacuum glass provided with edges sealed by sealing grooves and sealing strips and provided with mounting hole(s) is disclosed. The convex vacuum glass comprises upper glass and lower glass, and is characterized in that: the convex vacuum glass is provided with the mounting hole(s); the number of the mounting hole(s) is 1-4; peripheries of the upper glass and the mounting hole(s) are provided with sealing strips; corresponding positions of the periphery of the lower glass and the mounting hole(s) are provided with the sealing grooves and sealing strips; after being rapidly heated, the upper glass and the lower glass are subjected to sheet combining at a high temperature, and peripheries of the upper glass and the lower glass and the periphery of each mounting hole are welded under elevated pressure by metal solder in a vacuum furnace; and a sealed vacuum layer is formed between the upper glass and the lower 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 convex vacuum glass with mounting holes welded to the sealing strip groove edge sealing metal 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 the construction field; but there are also obvious The shortcomings are mainly low production efficiency, low production capacity, and inability to produce toughened vacuum glass, which limits its promotion and application in a wider range; the existing large-scale production of vacuum glass uses high temperature (430-480°C) atmospheric pressure The production process of under-sealing and low-temperature (180-300℃) vacuuming and then sealing. Because the edge-sealing temperature needs to be kept f...
