Embodiment

[0043] Embodiment: Referring to the accompanying drawings, the convex double vacuum laminated glass consists of an upper convex glass 1 , an intermediate glass 3 and a lower convex glass 2 . Its production method is as follows: First, according to the shape and size of the convex double vacuum laminated glass to be produced, three flat glasses of the required size are cut, and a sealing groove 4 is opened at the corresponding positions on the upper surface periphery of the middle glass 3 and the lower glass 2, and Carry out edging, chamfering, cleaning and drying treatment to the three pieces of glass; secondly, spray on the lower surface periphery of the upper glass 1 and the middle glass 3 to prepare a sealing strip 5, and then make a silver paste layer 6 on the surface of the sealing strip and the sealing groove. The intermediate glass 3 is sent directly into the tempering furnace for tempering treatment. Put the upper and lower pieces of glass into the mould, heat up to the...

Abstract

Metal-welded convex double-vacuum-layer glass provided with edges sealed by sealing grooves is disclosed. The convex double-vacuum-layer glass comprises upper glass, lower glass and middle glass, and is characterized in that: peripheries of the upper surfaces of the upper glass and the middle glass are provided with sealing strips; corresponding positions of the peripheries of the upper surfaces of the middle glass and the lower glass are provided with the sealing grooves; after the three sheets of glass are rapidly heated, the peripheries of the three sheets of glass are welded under elevated pressure by metal solder in a vacuum furnace; and two 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 convex-surface double-vacuum-layer glass welded with sealing 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 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 t...
