Embodiment 1
[0044] Embodiment 1: see figure 1, The convex low-altitude glass is composed of upper glass 1 and lower glass 2, the periphery of the two pieces of glass is welded together by low-temperature 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 low-altitude glass to be made, drill a through hole at the corner of the upper and lower glass respectively to form the installation hole 3, and install the hole 3 around the periphery of the lower glass 2. Sealing groove 6 is provided on the periphery of 3, and edge grinding, chamfering, cleaning and drying are carried out, and sealing strip 5 is prepared by mechanical spraying technology at the peripheral welding place of upper glass 1, the periphery of mounting hole 3 and the periphery of lower glass sealing groove, And use a dispensing machine to prepare support 7 on the upper and lower glass; secondly, put the upper ...
Embodiment 2
[0045] Example 2: see figure 2 The convex low-altitude glass is composed of an upper glass 1 and a lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass. The production method is as follows: firstly, the convex low-altitude glass is cut according to the shape and size of the produced convex low-altitude glass. A piece of flat glass and a piece of low-emissivity glass of the required size, choose the low-emissivity glass as the lower glass 2, drill a through hole at the corner of the upper and lower glass to form the installation hole 3, and set up a seal around the periphery of the lower glass 2 and the installation hole 3 Groove 6, and carry out edging, chamfering, cleaning, and drying, and use screen printing technology to print sealing strips on the periphery of the upper glass 1, the periphery of the mounting hole 3, and the periphery of the upper sealing groove 6 of the lower glass 2; Put two pieces of glas...
