Embodiment

[0039] 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, remove the film on the welding part of the low-emissivity glass, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and grind the upper and lower glass Edge, chamfering and cleaning, drying, use silk screen printing technology to print the sealing strip on the peripheral welding place of the upper and lower glass and the periphery and corresponding position of the air inlet 3 and print the support 8 on one of the glass at the same time; The piece of glass is sent into the tempering furnace for air-cooling and tempering to obtain tempered or semi-tempered glass...

Abstract

Glass-welded sealed plain vacuum glass with edges sealed by 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 respectively provided with at least one sealing strip. The peripheries of the lower glass and each air extracting hole are respectively provided with at least two sealing strips. The sealing strip of the upper glass is inserted between the sealing strips of the lower glass. After being rapidly heated, the upper glass and the lower glass are subjected to sheet combining at a high temperature, and the peripheries of the upper glass and the middle glass are welded under elevated pressure by glass solder in a heating furnace. Each air extracting hole is sealed on line by utilization of melted glass in a continuous vacuum furnace. 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 plane vacuum glass with glass welding sealing strip 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 sealin...
