Embodiment

[0036] Embodiment: Referring to the accompanying drawings, the plane double-vacuum laminated glass is composed of upper glass 1, middle glass 3 and lower glass 2. Among the three pieces of glass, at least the upper and lower glasses are tempered glass or semi-tempered glass, and the lower glass 2 or\and The middle glass 3 is also a 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 them around the upper surface of the middle glass 3 and the lower glass 2. A sealing groove 6 is set up at the welding place, and the three pieces of glass are ground, chamfered, cleaned, and dried; secondly, the sealing strip 5 is printed and prepared at the corresponding positions around the lower surface of the upper glass 1 and the middle glass 3, and the upper glass 1 The support 7 is prepared by printing or dispensing glue on the lower surfa...

Abstract

Glass-welded plain double-vacuum-layer glass provided with edges sealed by sealing grooves is disclosed. The plain double-vacuum-layer glass comprises upper glass, lower glass and middle glass, and is characterized in that: the lower surfaces of the upper glass and the middle glass are provided with sealing strips; the peripheries of the upper surfaces of the middle glass and the lower glass 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 are welded under elevated pressure by glass solder in a vacuum furnace; and two sealed vacuum layers are formed among the upper glass, the middle 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 plane double-vacuum-layer 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 th...
