Embodiment

[0039] Embodiment: Referring to the accompanying drawings, the plane double-vacuum laminated glass is composed of upper glass 1, middle glass 9 and lower glass 2. Among the three glasses, at least the upper and lower glasses are tempered glass or semi-tempered glass, and at least one of the glasses is still low. Radiation glass, its production method is as follows: First, according to the shape and size of the planar double vacuum layer glass to be produced, cut three pieces of flat glass of the required size, and drill a through hole on the upper glass 1 and the middle glass 9 respectively to form the air inlet 3 , wherein the through hole on the upper glass 1 is greater than the through hole on the middle glass 9, and the three pieces of glass are ground, chamfered, cleaned and dried; secondly, on the periphery of the upper glass 1, the lower glass 2 and the middle glass 9 Print and prepare the sealing strips 5 and 6 on the periphery of the welding place and the exhaust port ...

Abstract

Glass-welded sealed plain double-vacuum-layer glass with edges sealed by sealing strips is disclosed. The plain double-vacuum-layer glass comprises upper glass, lower glass and middle glass which are plain glass. The upper glass and the middle glass are provided with one to four air extracting holes. The periphery of the lower surface of the upper glass, the periphery of the lower surface of the middle glass and the periphery of each air extracting hole are respectively provided with at least one sealing strip. The peripheries of the upper surfaces of the middle glass and the lower glass are provided with at least two sealing strips. A position on the lower glass, which is corresponding to each air extracting hole, is provided with at least one sealing strip. After the three sheets of glass are rapidly heated, the peripheries of the three sheets of 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. A manufacturing method of the plain double-vacuum-layer glass is 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 double-vacuum-layer 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 th...
