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-tem

Embodiment 1

[0055] 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. On the upper and lower glass, the low-temperature glass powder paste is printed into an edge sealing strip frame by using a polyester screen and on the upper or lower glass using polyester The ester screen is used to print the low-temperature glass powder paste into a support; 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; Under the high temperature of 550~650℃ in the high temperature furnace, the edge banding frame and the support are softened or melted and bonded with the glass, and then lowered to room temperature; if the shape of the edge banding frame or the support changes during the high temperature sintering proc...

Embodiment 2

[0058] 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 set up, and edge grinding, chamfering, cleaning, and drying are carried out. The upper and lower glass is printed with low-temperature glass powder paste into an edge sealing strip frame by printing technology. After the upper and lower glass are combined, the edge sealing strip of the upper glass is The frame can be embedded in the edge sealing groove of the lower glass; secondly, the upper and lower glass are sent to the high temperature furnace, and the edge sealing frame and the glass are sintered together under the high temperature of 550~650 °C in the high temperature furnace, and then lowered to roo...

Embodiment 3

[0060] Embodiment 3: see figure 1 , 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, set up edge sealing grooves at the peripheral welding of the lower glass, and perform edge grinding, chamfering, cleaning, and drying. Use a spray gun to make low-temperature glass powder paste into edge sealing strips on the upper and lower glasses. After the upper and lower glasses are combined , the edge banding frame of the upper glass can be fitted into the edge banding groove of the lower glass; secondly, the upper glass is sent into the tempering furnace, and the edge banding frame is sintered with the glass under the high temperature of 650~750°C in the tempering furnace Together, air-cooled tempering is carried out immediately to obtain tempered or semi-tempered glass; on the upper glass, low-temperature glass solder is used to print supports using tensioned steel mesh or steel screens, so that th...

The manufacturing method has characteristics of simple process, low cost, high production efficiency, reliable sealing and good sealing effect. With the technology, large mass manufacturing of the vacuum glass with no gas exhaust port through the one-step method can be achieved. In addition, with the method, the universal vacuum glass can be manufactured, and the tempered vacuum glass can be manufactured.

Description

technical field [0001] The invention relates to the processing and manufacturing of vacuum glass, in particular to a method for making vacuum glass and its products. Background technique [0002] Vacuum glass is a new type of energy-saving and environmentally friendly product, which can be widely used in industrial and agricultural fields such as building doors and windows, glass curtain walls, solar products, agricultural greenhouses, refrigerators and refrigerators, and daily necessities for residents. Soundproofing and finishing materials. In the process of making vacuum glass, the structure and technology of edge sealing is the key technology to ensure that the periphery of vacuum glass is not deformed, does not produce excessive stress, does not leak air, and maintains the characteristics of tempered glass. 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 ...
