Embodiment
With specific embodiment, the present invention is further expalined below, but is not limited to protection scope of the present invention.
Carrying out in vacuum glass making and edge sealing working process in the past, on realizing, sealing-in between lower sheet glass, need upper, lower sheet glass is all placed in process furnace and carries out entirety heating, then pass through upper, after the glass powder melting that lower sheet glass is arranged, by upper, bottom sheet glass sealing, the space taken in whole edge sealing work is large, consumption of calorie is many, and operational difficulty, cycle is long, yield poorly, the demand grown with each passing day on the market cannot be met, in order to solve the problem, present embodiment provides a kind of edge bonding method of vacuum glass, in the method, local emphasis heating is carried out to needing the vacuum glass side carrying out edge sealing mainly through high hot blast, be similar to heat-processed and the principle of Blowing drum, to reduce the consumption of heat, specific as follows:
I) side of pre-for vacuum glass sealing-in is positioned over the side of high hot air source, open high hot air source, that hot blast is blown away to vacuum glass direction via pre-sealing-in side, to realize carrying out local emphasis heating to the side of vacuum glass, finally realize vacuum glass to be successively decreased in gradient to center position elongating temperature by pre-sealing-in side, produce by the phenomenon of thermal breakage effectively to prevent glass;
II) when the heating side edges of the pre-sealing-in of described vacuum glass is to molten state, sealing part implantation glass liquid between the upper sheet glass and lower sheet glass of described vacuum glass is also floating, cooling, complete edge sealing, because glass only just can realize bonding each other under the state of melting, and stability is high, therefore, need the heating side edges of pre-for vacuum glass sealing-in to molten state.
Wherein, described upper sheet glass and lower sheet glass can select simple glass or toughened glass.
If the side of hot blast to vacuum glass that directly use temperature is higher heats, also the phenomenon of glass rupture can be there is, in order to improve yield rate, as the improvement of technical scheme, can by step I) in the type of heating of heating source to described vacuum glass side select sectional type laser heating, specifically be divided into successively: the heating of low-temperature prewarming, middle temperature and heat three successive stage, wherein, the temperature of described low-temperature prewarming is 50 ~ 200 DEG C, the temperature of described middle temperature heating is 200 ~ 600 DEG C, the temperature of described heat is 600 ~ 1000 DEG C.
In order to realize large-scale production and the flow work, can by step I) in the position of heating source fix, vacuum glass is moved relative to described heating source, realize the heating for pre-sealing-in side, can vacuum glass be positioned on transmission belt in the production process of reality, the side of travelling belt or above be provided with heating source, realize vacuum glass moving relative to heating source by the transmission of travelling belt, complete the local heating for vacuum glass.
In order to reduce the probability of glass rupture further, as the improvement of technical scheme, described Step II) in the glass metal that injects be that cryogenic glass powder heating forms, and the temperature of described glass metal lower than/equal the side temperatures of the pre-sealing-in of described vacuum glass, thus effectively avoid bursting of glass.
Introduce the detailed process utilizing above-mentioned edge bonding method to carry out vacuum glass making below again, specific as follows:
1) according to specification, upper sheet glass and lower sheet glass are cut, and clean up, for subsequent use;
2) lay upholder dot matrix in the side of lower sheet glass, and the surrounding of lower sheet glass is provided with glass binder, the preferred high-temperature plastic of this binding agent;
3) described upper sheet glass is withheld the top in described lower sheet glass, bondd by the surrounding of described glass binder by described upper sheet glass and described lower sheet glass, form one;
4) side of described upper sheet glass and the pre-sealing-in of described lower sheet glass is positioned over the side of heating source, heat, wherein, described heating source is hot blast;
5) when the heating side edges of described pre-sealing-in is to molten state, the sealing part implantation glass liquid on described between sheet glass and lower sheet glass is also floating, and cooling, completes edge sealing;
6) the edge sealing place of sheet glass and lower sheet glass inserts medical needle on described, and one end of described medical needle communicates with the seal cavity formed between described upper sheet glass and lower sheet glass, and the other end is connected with vacuum pump, vacuumizes described seal cavity;
7) after vacuumizing end, use electric arc welding device to be blocked by described medical needle, and form solder joint in described truncated position, use the glass metal of molten state to carry out shutoff at described solder joint place, described electric arc welding device can select laser electric arc welding device.
Wherein, the insertion of conveniently medical needle in step 6), can in advance in the edge sealing place boring of upper sheet glass and lower sheet glass, and described medical needle is inserted by this aperture place.
The method vacuumized vacuum glass that the present embodiment provides is extracted by medical needle, and be upper, sealing-in place of lower-glass is inserted, blocked by welding machine after vacuumizing end, again by the shutoff of molten glass metal, can't see the position of syringe needle in appearance, and due to medical syringe needle thinner, the phenomenon causing very large hole to cause leaking gas to sealing-in place can be avoided to occur, well ensure that the vacuum tightness of vacuum glass, and avoid vacuum glass in the past and on the glass of side, leave one vacuumize hole, hole is closed by metal cap, bring difficulty to transport and construction.
Wherein, because the heat transfer of vacuum glass centre is made up of radiative transfer and upholder heat transfer, in order to reduce the hot/cold conduction of this vacuum glass further, preferably, above support is spheroid, and itself and upper sheet glass and lower sheet glass are point cantact, effectively reduces hot/cold conduction, more preferred, described spheroid is micro-steel ball or glass microballon.
In order to upper sheet glass can either with bottom sheet glass bonding, can connect with upholder again, being somebody's turn to do as technical scheme, make described step 2) in the glass binder height of relatively going up sheet glass be greater than the height that above support goes up sheet glass relatively, because glass binder has certain elasticity, when upper sheet glass is withheld above lower sheet glass, the height of glass binder can reduce, now go up that sheet glass is very good can contact with upholder, improve the quality of vacuum glass.
Consistent with edge bonding method, in preferred described step 4), the heating side edges mode of heating source to described upper sheet glass and the pre-sealing-in of described lower sheet glass is sectional type laser heating, be specially: the heating of low-temperature prewarming, middle temperature and heat three successive stage, wherein, the temperature of described low-temperature prewarming is 50 ~ 200 DEG C, the temperature of described middle temperature heating is 200 ~ 600 DEG C, the temperature of described heat is 600 ~ 1000 DEG C.
Experimental test
Ordinary insulating glass, 10 layers of simple glass and single-glass that the vacuum glass using aforesaid method to make, market are sold are carried out actual test, specific as follows:
4 bowls being loaded with 50 DEG C of hot water are positioned on desk, respectively above-mentioned vacuum glass, double glazing, 10 layers of simple glass and individual layer simple glass are positioned over after on 4 bowls being loaded with 50 DEG C of hot water successively and carry out temperature survey first, after 10 minutes, carry out second test again, concrete test data is in table 1.
Table 1: temperature data table
By the vacuum glass that the known use of table 1 method provided by the invention is obtained, its performance every hot/cold is better, is all better than double glazing, 10 layers of simple glass and single-glass, meets the requirements.
