Problems solved by technology

In the patent CN94192667.2 "Method for Manufacturing Vacuum Glass Windows", the edge sealing structure is designed so that the upper glass is slightly smaller than the lower glass in the two glasses, and the low melting point glass solder is placed on the edge steps formed by the two glasses, and the melted glass Solder flows into the gap between two pieces of glass due to capillary phenomenon. This method is the most representative and practical edge sealing technology at present, but it has the disadvantages of large amount of solder, uneven edges and high stress; patent CN95108228.0 "vacuum Flat glass and its manufacturing method" and CN96208977.X "vacuum flat glass", the edge of the glass plate is used to "chamfer" first, and the solder is placed in the chamfering groove. This method has the difficulty of distributing and the low-melting point glass solder is heated. Deficiencies that are easily lost during fusing and sealing; the patent CN02256440.3 "vacuum glass edge sealing structure" is to put auxiliary sealing strips on the upper periphery of the lower flat glass to prevent the loss of solder liquid. Although this method solves the problem of solder liquid's outward loss , but the process is complicated, and the auxiliary sealing strip takes up a large space, and it cannot solve the problem that the solder liquid flows into the glass; the edge sealing method of the vacuum glass proposed in the patent CN200620070302.7 "fully transparent vacuum glass" is to make the edge of the glass together with the glass The disadvantage is that the edge banding is not only expensive to manufacture but also cannot restrict the flow of low-temperature solder to the inside of the glass; patent CN200920314752.X "Edge banding structure of vacuum glass" is based on the glass and the The top glass and/or the base glass between the edge of the glass is made with a geometric filling groove, although it can improve the adhesion of the sealing filler between the base glass and the top glass, but the filling groove of the upper and lower glass is difficult. At the same time, the sealing packing is filled, and the random flow of the sealing packing cannot be restricted; Patent CN201010228110.5 "A Vacuum Glass Edge Sealing Method" is to put glass welding material around the periphery of the vacuum glass original plate, and set a layer inside the glass welding material The inner anti-seepage layer made of powdery or fibrous materials restricts the glass solder liquid from flowing

Example Embodiment

[0061] 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...

Example Embodiment

[0064] 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℃. ...

Example

[0066] Example 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 printed on the upper glass to form an edge sealing strip frame. There is an edge banding frame, and the lower glass has 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; First print or spray a layer of paste containing low-temperature glass powder on the position of the side groove, and then print or spray a layer of commercially available silver paste as a transition layer; secondly, send the upper glass into the tempering furnace, in the tempering furnace 650~ Under the action of high tempera...
