[0041] 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 according to the shape and size of the convex vacuum glass to be produced, and drill a through hole at the corner of the upper glass 1 and the lower glass 2 as the air inlet (installation hole) 3, Open the sealing groove 6 at the periphery of the lower glass 2 and the corresponding place of the air outlet 3, and perform edge grinding, chamfering, cleaning, and drying. Use mechanical spraying technology to prepare the sealing strip 5, and use a dispenser to prepare the support 8 on the upper and lower glass; secondly, put the upper and lower pieces of glass into the mold, put them in a bending furnace, and heat up to the softening temperature of the glass at 550-750°C. The gravity of the ...
