Embodiment 1
[0063] Embodiment 1: see figure 1, a planar vacuum glass with an edge-sealing groove and three seals, two pieces of glass are tempered glass, one of which is low-emissivity glass, the production method is as follows: firstly cut the required vacuum glass according to the shape and size A piece of flat glass and a piece of low-emissivity glass, and set up an edge sealing groove 7 on one of the glasses, and then perform edge grinding, chamfering, cleaning, and drying; secondly, send the two pieces of glass into a tempering furnace for Toughening treatment, then prepare support 6 with polyimide adhesive and glue applicator respectively on two pieces of glass, support 6 is line shape, after two pieces of glass are combined, upper and lower support 6 intersects together; Or use a coating machine to evenly coat two low-temperature glass solders and one magnesium alloy powder on the periphery of two pieces of glass. The magnesium alloy powder is located between the two glass solders ...
Embodiment 2
[0065] Example 2: see figure 2 , a flat vacuum glass with two edge-sealing grooves and two seals. The two pieces of glass are tempered glass, one of which is still low-emissivity glass. The production method is as follows: firstly, cut the required A piece of flat glass and a piece of low-emissivity glass of the same size, and set up a corresponding upper and lower edge sealing groove 7 on each of the two pieces of glass, and then perform edge grinding, chamfering, cleaning and drying; Glass ink and dispensing machine to prepare support 6, the support 6 is a long strip, after the two pieces of glass are combined, the upper and lower supports cross together, and then the two pieces of glass are respectively sent into the tempering furnace for tempering treatment, the prepared The support 6 is also sintered on the glass; the sintered support 6 is mechanically ground again so that its top is in a plane, and the top edge after grinding is rounded to further eliminate the influenc...
Embodiment 3
[0069] Embodiment 3: see image 3 , a planar vacuum glass with two edge-sealing grooves and three seals, two pieces of glass are tempered glass, one of which is low-emissivity glass, the production method is as follows: firstly cut the vacuum glass 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 of the required size, and two edge sealing grooves 7 are set on the upper glass 1, and then edge grinding, chamfering, cleaning and drying are carried out; secondly, the two pieces of glass are sent to the tempering furnace respectively Perform tempering treatment; use polyimide adhesive and dispenser to prepare support 6 again, support 6 is cylindrical, and then evenly coat two layers of polyimide on the periphery of a piece of glass or two pieces of glass with a coating machine Adhesive and a magnesium alloy powder, the two polyimide adhesives correspond to the two edge grooves 7 respectively, the magnesium ...
