[0040] Example: see figure 1 , The convex vacuum glass is composed of an upper glass 1 and a lower glass 2, the periphery of the two pieces of glass is welded together by glass solder 4, 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 to form a suction port 3, and grind and chamfer the upper and lower glass And clean, dry, utilize mechanical spraying technology to prepare sealing strip 5 and 6 at the peripheral welding place of upper and lower glass and the periphery of air inlet 3 and corresponding place, and prepare support 8 on upper and lower glass with dispenser; Put the glass into the mold, put it in the hot bending furnace, heat up to the temperature of glass softening 550-750 ℃, rely on the gravity of the glass itself to make the glass downward to form a convex surface...
