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 production 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 drill a pass on the upper glass 1 and the middle glass 9 respectively. The holes form the air suction port 3, wherein the through hole on the upper glass 1 is larger than the through hole on the intermediate glass 9, and the sealing groove 6 is set at the upper surface periphery of the intermediate glass 9 and the lower glass 2 and the periphery of the air extraction port 3 and corresponding positions, and Carry out edging, chamfering, cleaning and dryi...
