Embodiment
[0044] Embodiment: Referring to the accompanying drawings, the plane double-vacuum laminated glass is composed of upper glass 1, middle glass 9 and lower glass 2. Among the three pieces of glass, at least the upper and lower glasses are tempered glass or semi-tempered glass, wherein the lower glass 2 or\and The middle glass 9 is still low-emissivity glass, and its manufacturing method is as follows: first, cut three pieces of flat glass of required size according to the shape and size of the flat double-vacuum glass to be made, and place the upper glass 1, the middle glass 9 and the lower glass 2 A through hole is drilled at the corner of the upper glass 1 as the air outlet (installation hole) 3, wherein the through hole on the upper glass 1 is larger than the through hole on the middle glass 9, and the upper surface periphery of the middle glass 9 and the lower glass 2 and the air outlet 3 Sealing groove 6 is set up at the periphery and the corresponding place, and the three p...

Abstract
High-temperature-sheet-combination 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: 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 peripheries of the upper surfaces of the middle glass and the lower glass and each air extracting 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 peripheries of the upper glass, the middle glass and the lower glass are welded under elevated pressure by glass solder in a heating furnace; and each air extracting hole is automatically sealed by utilization of metal solder in a vacuum furnace. 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 flat double-vacuum-layer glass with mounting holes on the edge of a high-temperature laminate sealing groove 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 ...
