Embodiment
[0043] Embodiment: Referring to the accompanying drawings, the vacuum glass is composed of an upper glass 1 and a lower glass 2. The two glasses are tempered glass or semi-tempered glass, and one of them is low-emissivity glass. The manufacturing method is as follows: first, according to the shape of the vacuum glass produced Cut a piece of flat glass and a piece of low-emissivity glass according to the required size, choose the low-emissivity glass as the lower glass 2, drill a through hole at the corner of the upper glass 1 and the lower glass 2 as the air outlet (installation hole) 3, and insert Set up a sealing groove 6 around the periphery of the glass 2 and the corresponding part of the air outlet 3, and perform edge grinding, chamfering, cleaning, and drying, and use screen printing technology or dispensing on the peripheral welding of the upper glass 1 and the periphery of the air outlet 3 technology to make the sealing strip and the support 9 at the same time, and then...

Abstract
High-temperature-sheet-combination plain vacuum glass provided with edges sealed by sealing grooves and provided with mounting hole(s) is disclosed. The plain vacuum glass comprises upper glass and lower 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; 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; 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 are welded under elevated pressure by glass solder in a heating furnace; each air extracting hole is automatically sealed by utilization of metal solder in a vacuum furnace; a sealed vacuum layer is formed between the upper glass and the lower glass; and 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 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 vacuum glass with mounting holes on the sealing edge of a high-temperature laminated 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 warm...
