Abstract
The invention discloses a vacuum glass metal edge sealing technology. An edge sealing strip is included; each of the upper side and the lower side of the edge sealing strip is coated with a layer of welding glass powder sealing adhesive. The vacuum glass metal edge sealing technology is characterized in that 1, the edge sealing strip adopts an integral U-shaped flexible thin-wall structure; 2, after welding glass powder is melted, and before bubbles are produced, acting force is applied between a glass plate and the edge sealing strip to bond the glass plate and the edge sealing strip together.
Description
Technical field
The invention belongs to vacuum glass manufacture field, especially a kind of vacuum glass metal sealed edges technique.
Technical background
Current vacuum glass is mainly with the sealing of glass for bonding powder.The temperature difference (indoor/outdoor temperature-difference) on vacuum glass two sides causes vacuum glass generation buckling deformation.Vacuum glass will be caused to break when buckling deformation is too large, in order to prevent buckling deformation too large, generally outside vacuum glass, add one deck double glazing, reducing the temperature difference with this, reducing vacuum glass buckling deformation.The way welding metal sealed edge that Chinese patent application 2011204276188 proposition is welded by metal spraying, this method can solve vacuum glass buckling deformation problem, but complex process, operate more difficult.
Summary of the invention
The object of this invention is to provide a kind of vacuum glass metal sealed edges technique.Eliminate vacuum glass buckling deformation with this, simplify welding process.
Technical scheme of the present invention is: a kind of vacuum glass metal sealed edges technique, comprises edge band, edge band and scribbles one deck glass for bonding powder sealing cement up and down, it is characterized in that: 1, edge band is an overall U-shaped flexible thin wall construction; 2, between sheet glass and edge band, apply reactive force before producing bubble after the fusing of glass for bonding powder, force sheet glass and edge band to be bonded together.As shown in Figure 1, this is overall U-shaped edge band, edge band be one overall.As shown in Figure 2, this is U-shaped edge band schematic cross-section, and cross section is U-shaped structure.The object of U-shaped structural flexibility edge band is adopted to be eliminate vacuum glass buckling deformation, when there is the temperature difference on vacuum glass both sides, the one side of catching a cold is shunk, during one surface expansion of being heated, because edge band is U-shaped flexible structure, larger distortion can be born, be out of shape by edge band and adapt to sheet glass distortion, thus eliminate vacuum glass buckling deformation.
Above-mentioned vacuum glass metal sealed edges technique, it is characterized in that: the metal material of the vacuum glass metal sealed edges technique U-shaped preferred coefficient of expansion of structural flexibility edge band and glass for bonding powder expansion coefficient similar, also can select other material of the coefficient of expansion and glass for bonding powder expansion coefficient similar.
Above-mentioned vacuum glass metal sealed edges technique, is characterized in that: heat fused glass for bonding powder is in vacuum furnace.Glass for bonding pruinescence heat fused process is such: 1, melt first completely, now glass for bonding powder melt thickness and wetting property is poor, also poor with the cohesiveness of levels sheet glass, and middle containing some small bubbles, resistance to air loss is also bad; 2, heating glass for bonding powder melt is continued, glass for bonding powder melt starts a large amount of bubble of emerging, along with temperature raises, under the acting in conjunction of defoamer, removal of bubbles, glass for bonding powder melt viscosity reduces, and wetting property and resistance to air loss improve, under gravity, levels sheet glass and middle edge band are bonded together.Melt completely at glass for bonding powder, but just on levels sheet glass, apply pressure before also not bubbling, under the effect of the pressure, the glass for bonding powder melt of thickness becomes a very thin skim, so just levels sheet glass and edge band are sticked together closely, the compressing of external force simultaneously also inhibits the generation of bubble in glass for bonding powder melt, and suppresses former alveolate expansion, adds the resistance to air loss of glass for bonding powder melt.As shown in Figure 3, a large amount of bubble of emerging is started at glass for bonding powder melt, along with temperature raises, under the acting in conjunction of defoamer, removal of bubbles, glass for bonding powder melt viscosity reduces, and glass for bonding powder melt will run off, the glass for bonding powder melt between U-shaped structural flexibility edge band and lower glass plates 4 will be caused like this to reduce in a large number, cannot seal.Then can not run off when glass for bonding powder melt viscosity is larger.Due to be glass for bonding powder just completely fusing time just apply pressure and force levels sheet glass and edge band to stick together closely, and do not need the complete froth breaking of glass for bonding powder melt at a higher temperature by the time, which reduce heat-up time.
Usefulness of the present invention is to eliminate vacuum glass buckling deformation, simplifies welding process, decreases heat-up time.

Embodiment
If Fig. 3 is the vacuum glass raw sheet schematic diagram adopting overall U-shaped flexible thin wall construction edge band, vacuum glass raw sheet comprises upper glass plate 1, lower glass plates 4, edge band 3, supporter 5, sealing cement glass for bonding powder 2, and edge band about 3 has sealing cement glass for bonding powder 2.Have space near between the supporter and upper glass plate of vacuum glass panel edges, such guarantee upper glass plate can be depressed.Heating, vacuum glass raw sheet in heating under vacuum Sealing furnace, vacuum furnace and vacuum glass raw sheet intermediate gas is extracted out while heating, by the time when sealing cement glass for bonding powder 2 melts also do not emit bubble in a large number completely, vacuum glass raw sheet levels sheet glass applies pressure f, thinner by what press at the effect lower seal binding agent glass for bonding powder 2 of pressure f, levels sheet glass and sealed strip are bonded together, stop heating progressively cooling, vacuum glass is cooled to come out of the stove close to after room temperature by the time.As shown in Figure 4, U-shaped flexible thin wall construction edge band 3 cross section have a point deformation near between the supporter and upper glass plate of vacuum glass panel edges without space, supporter is played a supporting role to levels sheet glass.
Fig. 5 is the hollow plate glass schematic diagram of the overall U-shaped flexible thin wall construction edge band adopting outsourcing, wrap in outside hollow plate glass outside overall U-shaped flexible thin wall construction edge band, by the time when sealing cement melts also do not emit bubble in a large number completely, pressure f 1 is applied outward at overall U-shaped flexible thin wall construction edge band, thinner by what press at the effect lower seal binding agent of pressure f 1, levels sheet glass and sealed strip are bonded together.
