Embodiment 1
[0057] Example 1: see figure 1 The vacuum glass consists of upper glass 1 and lower glass 2. The two pieces of glass are tempered glass or half-tempered glass, one of which is low-emissivity glass. The production method is as follows: First, cut the required size according to the shape and size of the vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass, the low-emissivity glass is selected as the lower glass 2, a through hole is drilled at the corner of the upper glass 1 as the air outlet 3, and a sealing groove is provided around the periphery of the lower glass 2 and at the corresponding place of the air outlet 3 6, and carry out edge grinding, 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 air inlet 3, and the periphery of the upper sealing groove 6 of the lower glass 2, and at the same time print the sealing strip on the At least one p...
Embodiment 2
[0058] Example 2: see figure 2 , the vacuum glass is composed of upper glass 1, middle glass 9 and lower glass 2, at least the upper and lower glass of the three pieces of glass are tempered glass or semi-tempered glass, wherein the lower glass 2 or\ and middle glass 9 are also low-emissivity glass, which The production method is as follows: First, cut three pieces of flat glass according to the shape and size of the vacuum glass to be produced, and drill a through hole on the upper glass 1 and the middle glass 9 respectively to form the air inlet 3, wherein the upper glass 1 The through hole is larger than the through hole on the middle glass 9, and the sealing groove 6 is set on the upper surface periphery of the middle glass 9 and the lower glass 2 and the periphery of the air suction port 3 and the corresponding positions, and the three glasses are ground, chamfered, and cleaned. , dry treatment; secondly, utilize toughened glass ink to print and prepare sealing strip 5 o...
