[0044] Example: see figure 1 , The convex vacuum glass is composed of upper glass 1 and lower glass 2, the periphery of the two pieces of glass is welded together by metal solder 7, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the vacuum glass to be produced, drill a through hole at the corner of the upper glass 1 and the lower glass 2 as the installation hole 3, and grind the upper and lower glass. Edge, chamfering and cleaning, drying, use mechanical spraying technology to prepare sealing strips 5 and 4 at the peripheral welding place of the upper and lower glass and the periphery and corresponding positions of the mounting hole 3, and prepare the support 8 on the upper and lower glass with a dispenser. Make a silver paste layer 6 on the sealing strip in contact with the solder and the surface of the glass; secondly, put the upper and lower pieces of glass in...
