Embodiment 1
[0058] Embodiment 1: see figure 1 , the vacuum 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 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 as the air outlet 3, and drill a through hole at the corner of the upper glass 1 as the air outlet 3, and drill a through hole on the periphery of the lower glass 2 and the air outlet 3 Set up sealing groove 6 at the corresponding place, and carry out edging, chamfering and cleaning, drying, utilize mechanical spraying technology to prepare sealing strip 5 at the peripheral welding place of upper glass 1, the periphery of suction port 3 and the periphery of lower glass sealing groove, And use a dispensing machine to prepare supports 8 on...
Embodiment 2
[0059] Example 2: see figure 2 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 peripheral welding part 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; Two pieces of glass are put into two forming molds r...
Embodiment 3
[0060] Embodiment 3: see image 3 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 on...
