Embodiment

[0044] Embodiment: Referring to the accompanying drawings, the flat vacuum glass is composed of an upper glass 1 and a lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, and one of them is a low-emissivity glass. The manufacturing method is as follows: Cut a piece of flat glass and a piece of low-emissivity glass according to the shape and size of the required size, select the low-emissivity glass as the lower glass 2, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and drill a through hole on the periphery of the lower glass 2 and the air outlet Set up a sealing groove 6 at the corresponding position of the air port 3, and perform edging, chamfering, cleaning and drying, and use screen printing on the peripheral welding place of the upper glass 1, the periphery of the air inlet 3, and the periphery of the upper sealing groove 6 of the lower glass 2. technology to print the sealing strip and print the support 9 on at l...

Abstract

Metal-welded sealed plain vacuum glass with edges sealed by sealing grooves and sealing strips is disclosed. The plain vacuum glass comprises upper glass and lower glass which are plain glass. The upper glass is provided with air extracting hole(s). The peripheries of the upper glass and each air extracting hole are provided with sealing strips. Corresponding positions of the periphery of the lower glass and each air extracting hole are provided with the sealing grooves and sealing strips. After being heated, the upper glass and the lower glass are subjected to sheet combination at a high temperature, and the peripheries of the upper glass and the lower glass are welded under elevated pressure by alloy solder in an atmosphere heating furnace. Each air extracting hole is sealed by utilization of metal solder in a vacuum furnace. A sealed vacuum layer is formed between the upper glass and the lower glass. Supports arranged in a point array are disposed in the vacuum layer. The vacuum glass and a manufacturing method thereof are simple in process and high in production efficiency. The manufactured vacuum glass eliminates edge sealing stress and maintains tempered characteristics of tempered glass. 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 vacuum glass with metal welded sealing strip groove edge sealing 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 the edge s...
