[0045] 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 according to the shape and size of the convex 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 drill a through hole in the corner of the lower glass 2. A seal groove 4 is set up at the periphery and the corresponding place of the mounting hole 3, and is ground, chamfered, cleaned, and dried, and the sealing strip 5 is prepared by mechanical spraying technology at the peripheral welding place of the upper glass 1 and the periphery of the mounting hole 3, and is applied with a dot The melter prepares the support 8 on the upper and lower glass, and then makes the silver paste layer 6 on the surface of the se...
