Embodiment 1
[0056] Embodiment 1: see figure 1 , the vacuum glass is composed of upper and lower pieces of glass, one of which is low-emissivity glass. Edge sealing grooves are opened at the welding place, and edge grinding, chamfering, cleaning and drying are carried out, and low-temperature glass powder paste is printed on the upper glass with polyester screen to make edge sealing strips and supports; the upper glass has two There are two edge-sealed frames and the lower glass has two edge-sealed grooves. After the upper and lower glass are combined, the edge-sealed frame of the upper glass can be embedded in the edge-sealed groove of the lower glass; the width of the upper glass edge-sealed frame is 1.5 mm, the height is 0.3mm, the width of the lower glass edge sealing groove is 2.5mm, and the depth is 0.5mm. The support is a lattice arrangement of equilateral triangles with the smallest unit. The side length of the triangle is 30mm, and the support is cylindrical. , with a diameter of...
Embodiment 2
[0059] Example 2: see figure 1 , the vacuum glass is composed of upper and lower pieces of glass, both of which are ordinary float glass, and its 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, and weld them on the periphery of the lower glass Edge sealing grooves are opened at the edge, and edge grinding, chamfering, cleaning and drying are carried out. On the upper glass, the low-temperature glass powder paste is printed into edge sealing strip frames by printing technology. The upper glass has two edge sealing strip frames, and the lower glass The glass has two edge-sealing grooves. After the upper and lower glass are combined, the edge-sealing strip frame of the upper glass can be embedded in the edge-sealing groove of the lower glass; secondly, the upper glass is sent to the high-temperature furnace, and the temperature of the high-temperature furnace is 550~650℃. ...
Embodiment 3
[0061] Embodiment 3: see figure 2 , one of the two pieces of vacuum glass is low-emissivity glass, and the other is tempered glass or half-tempered glass. For radiant glass, edge sealing grooves are set at the peripheral welding of the lower glass, and the edges are ground, chamfered, cleaned, and dried. On the upper glass, the low-temperature glass powder paste is made into an edge sealing strip frame with a spray gun, and the upper glass has a The edge banding frame and the lower glass have an edge banding groove. After the upper and lower glass are combined, the edge banding frame of the upper glass can be embedded in the edge banding groove of the lower glass; secondly, the upper glass is sent into the tempering furnace, Under the high temperature of 650~750℃ in the tempering furnace, the edge banding frame and glass are sintered together, and then air-cooled and tempered to obtain tempered or semi-tempered glass; low-temperature glass solder is used on the upper glass to...
