Embodiment
[0044] 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 pieces of glass, at least the upper and lower glasses are tempered glass or semi-tempered glass, wherein the lower glass 2 or\and The middle glass 9 is still low-emissivity glass, and its manufacturing method is as follows: first, cut three pieces of flat glass of required size according to the shape and size of the flat double-vacuum glass to be made, and place the upper glass 1, the middle glass 9 and the lower glass 2 A through hole is drilled at the corner of the upper glass 1 as the air outlet (installation hole) 3, wherein the through hole on the upper glass 1 is larger than the through hole on the middle glass 9, and the upper surface periphery of the middle glass 9 and the lower glass 2 and the air outlet 3 Sealing groove 6 is set up at the periphery and the corresponding place, and the three p...
