Background technique
The disclosure relates generally to the building glass of thermal conditioning, and more particularly to the hot building glass enhanced and is related to using
In the correlation technique and system that carry out hot enhancing to building glass (especially for thin building glass piece).
In heat (or " physics ") enhancing of building glass piece, the vitrifying that building glass piece is heated to above glass is turned
Then sheet surface is quickly cooled down (" quenching ") by the high temperature of temperature, the interior zone of sheet material is at the same time with more slow rate
It is cooling.Interior zone is more slowly cooling, because they are isolated by the thickness of building glass and rather low thermal conductivity.It is dispar
Cooling generates residual compressive stress in glass surface region, is put down by the tensile residual stresses in building glass central area
Weigh the residual compressive stress.
The heat enhancing of glass is different from the Chemical enhancement of glass, by changing near-surface region in the Chemical enhancement
In the Chemical composition that (pass through such as ion spread method) of glass generate bearing stress.Expanded some based on ion
In scattered method, can by the way that larger ion is changed into the exterior section compared with small ion come reinforcing glass near glass surface,
So as on the surface or surface is applied around compression (also referred to as negative tensile stress).Compression is construed to limit crack initiation
And/or it propagates.
The heat enhancing of glass is also different from the glass enhanced by the following method:Pass through two types of combination in the method
The glass of type enhances or arranges the exterior section of glass.In such method, the glass combination with different heat expansion coefficient
The layer of object combines or laminated together when hotter.For example, by the molten glass layers with relatively low thermel expansion coefficient (CTE)
Between sandwich the melten glass with higher CTE, when glass is cooling, the positive tension in inner glass compresses outer layer, thus again
The secondary compression that formed on the surface is to balance positive tensile stress.This bearing stress provides enhancing.
The building glass of heat enhancing has the advantage that relative to non-reinforced building glass.With non-reinforced building glass phase
Than the surface compression of the building glass of enhancing provides bigger resistance to fracture.Intensity increase usually with the amount of bearing stress
It is proportional.If sheet material has enough heat enhancings horizontal relative to its thickness, if that sheet material is damaged, then usually it will
It is divided into fractionlet without being divided into big fragment or elongated chips with sharp edges.As limited by the various standards established
, the glass for being divided into sufficiently small fragment or " stripping and slicing " can be described as safety glass or " complete tempering " glass, or sometimes referred to as
For " tempering " glass.
Because enhancing degree depends on the glass sheet surface during quenching and the temperature difference between center, more thin glass is needed
Will more high cooldown rate to reach given applied stress.Moreover, more thin glass usually requires higher bearing stress value and center
Stress value so as to fracture when realize stripping and slicing at little particle.Therefore, if not can not if, with a thickness of about 3mm or more
Realize that desired temper level is very challenging in small glass.
All aspects of this disclosure be also generally related to for enhance the stress distribution of its exterior section building glass or
Glass ceramics.Building glass and glass and ceramic product (such as building glass piece) can be used for being widely applied.The reality of these applications
Example include in building, family, hotel, office and other similar building body building window, single pane and more pane windows,
Indoor and outdoors window, vacuum thermal insulation glass window and safety glass window.

Specific embodiment
Applicants have realized that needing in the method and system of the building glass for heat enhancing and in resulting heat
The heat treatment of building glass is improved in terms of building glass piece of enhancing itself.For example, relatively thin but height optical quality builds glass
Glass sheet material (for example, building glass pane) and product including such building glass piece be for many applications it is useful, it is described
Using window, the building window of the inside and outside single pane and more panes for including building, family, office and similar structures
The layer or pane of family, vacuum insulated glass building (VIG) window etc..It will be appreciated that the compressibility of glass is very strong, but to resistance to surface
It is relatively weak in terms of power.By providing compression at sheet surface, (compression passes through at the center of not exposed surface
Power balances), the useful intensity of building glass piece dramatically increases.Although however, relative to alternative Enhancement Method (for example, changing
Learn enhancing, the enhancing based on lamination), traditional hot building glass enhancing is usually cheaper and more rapidly, but thin for enhancing builds
Build glass (for example, 2-3mm or smaller building glass piece), it is known that traditional hot building glass enhancing is not effective.It passes
The hot glass strengthening method of system is typically considered to be limited to thicker sheet glass, because enhancing is horizontal depending on during process for quenching
The temperature difference generated between glass sheet surface and center;And because of the heat conduction rate limitation of traditional Enhancement Method, due to usually sending out
The raw relatively uniform cooling on entire thin glass sheet, therefore, it is difficult to realize between thin building glass piece surface and center
The significant temperature difference.
On the other hand, enhanced by ion exchange thin building glass may be it is time-consuming and troublesome, such as need to extend
The period of building glass chemical bath.Directly different types of building glass is laminated to may need complicated manufacturer each other
Method is such as related to double overflow slot fusion draw.
Therefore, it is necessary to have cause enhancing to building glass with for various uses (such as window, work top,
Used in device etc.) particular stress distribution building glass or glass and ceramic product, the building glass or glass ceramics system
Resource density is lower and/or more unpainful method is made by being compared with the traditional method for product.Specifically, it is discussed herein
Method and system forms the building glass product with the stress distribution of exterior section of enhancing building glass, and then is used to subtract
Light cracking and destruction, while allowing various other required building glass quality (for example, geometry, surface quality, visible light
Transmissivity, flexibility etc.) so as to the use that facilitates in the application of various building glass.
This specification provide for using heat enhancing come produce highly reinforcing building glass material (and especially height
Enhancing thin building glass piece) improved method and system.Method and system solves the various of routine building glass strengthening method
Limitation, thus allow thickness be less than about 3mm, less than 2mm, less than 1.5mm, less than 1.0mm, less than 0.5mm, be less than about
High-caliber enhancing is realized in 0.25mm and building glass piece less than about 0.1mm.Specifically, applicant develop provide it is non-
The often system and method for high heat conduction rate, thus formed between building glass piece surface and center the sufficiently large temperature difference so as to
Enhancing or tempering are provided in very thin building glass piece.
The summary and limitation of conventional thermal tempering technology
Conventional commercial method for hot-reinforced glass includes:(or two kinds of technologies are used in radiation energy furnace or convection furnace
" integrated mode " furnace) in sheet glass is heated to predetermined temperature, then typically via by being blown against or along glass surface
The convection current of a large amount of surrounding airs is sent to carry out gas cooling (" quenching ").This method for gas cooling is mainly convection current, is thus led to
The mass motion (collective motion) of fluid is crossed to be conducted heat (by diffusion and advection), because gas is by heat from hot glass sheet
It takes away.
In conventional tempering method, certain factors can limit in sheet glass (especially thin glass sheet) and be typically considered to possibility
Enhancing amount.Be partially present limitation because the compression amount on finished sheet directly with the sheet surface realized during quenching
Temperature difference size between center is related.However, a possibility that temperature difference during quenching is bigger, and glass ruptures during quenching is got over
Greatly.For given cooling rate, rupture can be reduced by quenching since higher initial glass temperature.In addition, more
High initial temperature allows generally for tempered glass piece to realize the whole enhancing potentiality provided by high cooldown rate.However, quenching
Increasing sheet temperature when beginning also has the shortcomings that its is potential.For example, higher initial glass temperature may cause sheet material because of it
Become softer and excessive deformation, to limit the practical achievable temperature difference.
In conventional tempering method, sheet thickness also applies significant limitation to the temperature difference achievable during quenching.For
Given cooling rate during quenching, sheet material is thinner, and the temperature difference between surface and center is with regard to smaller.This is because for will in
The heart and the thickness of glass that surface is insulated are smaller.Therefore, the heat enhancing of thin glass usually requires higher cooling rate (with thicker glass
The hot reinforced phase ratio of glass), and therefore remove heat more quickly from glass outer surface and usually require significant energy consumption, with
Just the enhancing for generating the temperature difference between the inside and outside of sheet glass is horizontal.
For example, Fig. 1, which is shown, is used to blow enough surrounding airs and carry out " complete tempering " soda-lime glass (" SLG ")
Air blower needed for power (by kilowatt/every square metre of sheet glass area as unit of), depend on glass in millimeters
Glass thickness, based on the hot Enhancement Method of professional standard developed before 35 years.As used glass is thinning, required power is in finger
Increase severally.Therefore, the sheet glass of about 3mm thickness is the commercial glass of most thin complete hot tempering available for many years.
In addition, sheet material is thinner, a possibility that glass deformation, is bigger under given pliability (that is, in given viscosity).Cause
This, reduced thickness directly reduces the achievable temperature difference, and because the risk of sheet material deformation increases and tends to reduce using more
Machine of the high sheet temperature to obtain whole benefits of more high cooldown rate and prevent the glass as caused by more high cooldown rate from rupturing
Meeting.Therefore, in conventional convection gas glass strengthening method, higher cooling rate is accomplished by the following way:Increase empty
Gas velocity reduces air jet orifice to the distance of glass sheet surface, increases the temperature (when beginning to cool) of glass, and appoint
The temperature of selection of land reduction cooling air.
As nearest example, the performance curve of Fig. 2 (prior art) is to enhance equipment using the glass heat of the prior art
Publication.This improved equipment continues to use traditional air blowing convective methods to cool down glass, but by least in heating
Support the systematic substitution of glass for supporting the roller of glass during heating during final stage using air.It is connect in no roller
In the case where touching, glass can be heated to higher temperature (and higher pliability/lower viscosity) before quenching,
It is reported that allow to produce the complete tempered glass of 2mm thickness.As shown in Fig. 2, compared with using roller (curve O), using empty
Gas come support glass (curve N) to realize higher temperature under, the blower power reported needed for enhancing the sheet material of 2mm thickness from
1200kW/m2It is reduced to 400kW/m2。
Although it indicates the process for being able to produce the 2mm heavy sheet glass of complete tempering, such as shown in Fig. 3 (prior art),
The old curve O and new curve N of Fig. 2 is scaled to match the ratio of Fig. 1 and exemplify and (scheme by the convection current toughening method of state of the art
Shown in 2) realize performance improvement it is relatively small and only to sheet glass convection current enhancing in energy requirement first feed-forward nets in
Progressive change.In Fig. 3, the old curve O and new curve N of Fig. 2 is scaled to match the curve graph of Fig. 1 and be covered on it
(wherein old curve O is in 240kW/m2Top be truncated in order to check new curve N).From figure 3, it can be seen that working as thickness of glass
When being reduced to 2mm from 3mm, the technology indicated by curve N only slightly changes the performance curve of convection gas process for quenching.Height behaviour
Make point (for 2mm glass, blower power 400kW/m2) show and handled by this method compared with power needed for thin glass
Still there is great increase.Air-flow sharply increases, therefore required power shows, it is difficult to enhance using conventional convection gas
Method reaches while producing full tempered glass lower than the thickness of 2mm (as engineering practice and economic problem).In addition,
Required very high air-flow it is also possible that thin slice shape distortion.Therefore, in order to realize thickness less than 2mm glass it is complete
Tempering or in order to thermal expansion coefficient (" CTE ") be lower than using hot tempering soda-lime glass thermal expansion coefficient glass in
The complete tempering of 2mm is realized, applicant have determined that needing using another toughening method/system.
Also the hot Enhancement Method of substituted type of current commercial convection type gas enhancing is had attempted to, but every kind of method is in convection current
Gas enhancing aspect has certain disadvantages.Specifically, realizing that the typical alternative hot Enhancement Method of more high cooldown rate is logical
It often requires at least some liquid or solids to contact with glass surface, rather than is only contacted with gas.This with sheet glass contacts
The uniformity of glass surface quality, glass flatness and/or Enhancement Method may be negatively affected.These defects sometimes can be by
Human eye is discovered, when especially watching in reflected light.As described in more detail below, at least in some embodiments, originally
Disclosed thermally conductive tempering system reduce or eliminate it is such with contact relevant defect.
Contact enhancing using liquid (in the form immersed in liquid bath or working fluid and in spraying form)
Enhance higher cooling rate than convection gas to realize, but has and cause excessive thermal change on sheet material during cooling means
The shortcomings that change.During immersion or class immersion in liquid are sprayed or flow, due to the spontaneous production in liquid bath or liquid flow
Larger thermal change may occur in smaller area for raw convection current.In finer be sprayed, discontinuous spray droplet
Significant thermal change is also generated with the effect of nozzle spray pattern.Excessive thermal change is tended to increase in the heat contacted by liquid
Glass is caused to rupture during strong, this can mitigate by limitation cooling rate, but limitation cooling velocity is also reduced and be can be achieved
Gained intensity.In addition, the necessary processing of sheet material (is located or is maintained in liquid bath or liquid flows or liquid spray
In) also due to being physically contacted with sheet material and leading to physical stress and excessive thermal change, to also tend to cause during enhancing
It ruptures and limits cooling velocity and gained is slight.Finally, some liquid cooling methods (such as pass through oil immersion and various spraying skills
The high cooldown rate of art quenches) glass surface can be changed in this cooling period, thus it requires being moved later from glass sheet surface
Except glass material to generate satisfactory finish.
The enhancing of solid contact heat is comprising contacting the surface of hot glass with the colder surface of solids.Enhance as liquid contacts
Equally, excessive thermal change may be easy to produce in quenched period, as seen in liquid contact enhancing.Sheet glass
Surface smoothness, any defect of the consistency of hardened face or sheet thickness all can cause the bad of some region of sheet material to connect
Touching, and this bad contact may cause larger thermal change, tend to rupture glass and such as chankings during processing
Material may also lead to undesirable birefringent if surviving.Additionally, hot glass sheet is made to contact can lead to solid objects to be formed
Surface defect, chip, check, cracking, crackle, scratch etc..With the increase of sheets of sizes, in the whole surface of sheet glass
Upper realization good physical contact may also become more and more difficult.Physical contact with the surface of solids can also during quenching machine
Sheet material is suppressed to tool, to increase a possibility that destroying sheet material during the method.In addition, start contact when hypervelocity temperature
Degree changes the rupture that can lead to during thin slice processing, and therefore the contact cooling of thin glass substrate is commercially infeasible
's.

While sheet glass is by air supporting, cooling sheet material:1) by conduction rather than by convection current (passing through gas to radiator), and
And 2) it is enough to generate or fix the thermotropic bearing stress of sheet material and thermotropic center tensile stress under environment temperature.

In case, gas is delivered to be formed in the air bearing that radiator nearby supports building glass piece.In some embodiments, only lead to
It crosses the aperture of radiator or only delivers gas by one or more holes of porous radiator and aperture.
These and other correlation techniques of the disclosure, as refrigerating mode is dominated rather than convection current, are violated by using conduction
The gaseous exchange cooling technology of current dominant.Method described herein is not the heat using solid and gas (glass and air)
Exchange, but use solid and solid (glass and radiator) heat exchange, by a small amount of gas (for example, glass surface and
It is not physically contacted between radiator) it is reconciled in small―gap suture, to start and complete to generate the cooling of heat enhancing.Although in gas
There are some convection current when body (for example, air bearing gas) flows into small―gap suture, but pass through gas and enter the direct of radiator
Across gap conduction is leading refrigerating mode.Applicant have determined that relative to the cooling means based on convection current, the advantage of heat transfer
Increase rate of heat transfer.
Because the conduction (or even across gap) of solid and solid allows heat flow more faster than convection current, relatively thin building glass
Cooling rate increase needed for glass piece is not limited by gas velocity and volume.According to various embodiments, not usually by
In the case where the constraint that gas flowing and gap size in contracurrent system apply, it can be selected for other purposes, control or excellent
Change gas flowing and gap size, such as control the rigidity of the air cushion in gap, be used to support sheet material, for flattening or
Otherwise make sheet forming, for optimize it is thermally conductive, for kept during heat enhancing sheet flatness and/or shape and/
Or for balancing sheet material ease of handling and high cooldown rate.For example, in some embodiments, because cooling is not by right
Stream, so while the low-down gas flow rate of support gas bearing, helium become economically may be used in the system of the disclosure
Capable air substitute, and in such embodiment, helium provides the thermal conductivity for being about five times in air.Even if price is assumed to be
The several times of currently available price, helium also become economically feasible alternative solution under the low flow velocity of the system of the disclosure.
In addition, because the system of the disclosure reduces the volume (phase in the air of building glass on piece flowing during cooling
For contracurrent system), so the system and method being discussed herein reduce typically by routine based in the tempering system of convection current
The potential risk of required high speed, the thin building glass piece deformation of the caused heat of high volumes of air flowing.This also allows do not becoming
Softer, higher temperature building glass piece is handled in the case where shape or minimal deformation, to be further improved achievable increasing
Strong degree.Eliminate upper air current speed also mitigate sometimes in the following areas in the problem of seeing:It is (inverse that sheet material is transported to quenching chamber
The dynamic movement of upper air current) and prevent high flowing, cooler air from entering and the adjacent part of the cooling furnace for heating plate.
Contact with conventional liq or solid contact quenching tempering correlation in addition, can be mitigated by use of the conduction of gas
Contact damage, warpage, forming of connection etc..Using gas keeps adding by avoiding contact of the solid with solid as middle conductor
The surface quality of work product.High conduction rate, which is reconciled, by gas also avoids liquid contact.Some type of liquid hardening can
Cause undesirable deformation, the pollution of the spatial variations in tempering and glass surface.These embodiments mainly provide non-
Contact the cooling of (in addition to gas) but very high speed.In other embodiments, as set forth above, it is possible to include that solid or liquid connect
Touching.
The power consumption of hot tempering system/method
Another advantage of upper air current speed is avoided to be to conduct by using solid-gas-solid as main building
The saving of power and energy that glass cooling body is realized.The point A and B of Figure 18 and Figure 19 indicates every square metre of building glass piece
The high-end estimation (being supplied by the compressed air under relatively high flowing) that the peak power of air bearing uses.Compressed air
Practical low side peak power using may as low as institute's indicating value 1/16.Point A and point B does not include the active cooling of radiator, however,
It may include in some embodiments, especially in the case where machine is in continuous, quasi-continuous or high-frequency operation.
Referring again to Figure 18 and Figure 19, point A' and B' indicate when considering the active cooling of spreader surface in point A and
The peak power level of the conservative estimation of air bearing operation at point B, it is assumed that by mechanical (or electricity) the efficiency ratio of heat-be 7.5 to 1
Active Cooling System come complete 300 DEG C be equivalent in building glass piece temperature of decline thermic load (for point A ' decline
Within 2.1 seconds time limits and for point B ' in 1 second).(these points are approximately corresponding in equipment described herein by practical steel
The building glass piece of change.)
Although four points in the region R of Figure 18 and Figure 19 show the improvement as obtained by disclosed method and system
Importance (at least to a certain extent), it should be noted that because power demand be represented quantity, attached
Whole incomes may be significantly underestimated in figure.For example, the peak power of air blower cannot effectively be beaten as represented by curve N
It is open and close, it usually needs gate air flue is to stop big fan, the big fan still rotation (but load when not needing air
Reduce).It usually can more effectively adapt to the fluid cooling system (such as cooling water factory) being for example easily achieved according to the disclosure
Peak power requirements (being indicated by point A' and B'), and effective peak power will be significantly reduced, thus only close to complete
Just close to A' and B' when continuous operation.Therefore, as shown, tendency is greater than peak value energy demand by the difference of total energy demand
Difference.In some embodiments, peak power possessed by process as described herein is less than 120Kw/m2, be less than 100Kw/m2、
Less than 80KW/m2So that heat enhancing is with a thickness of 2mm or smaller building glass piece.

In general, in the system and method for the present invention, the heat transfer from thin building glass piece includes conducted component, right
Flow component and radial component.It explains in detail as noted above and herein, the hot tempering system of the disclosure passes through utilization
Heat transfer provides thin building glass tempering as the principal organ for quenching thin building glass piece.
It is understanding of the applicant to basic theory below.The those of ordinary skill in glass tempering technology field can be easy to
Expect, wherein conduction effect is usually so small that in being typically ignored to be conducive to independent analysis convection current and radiation very much, is ask
Whether ask by the conduction via gas (such as air) can actually realize thin building glass piece (such as at 2 millimeters and following)
Sufficiently high cooling rate-and if so, if such rate can be realized under actual gap size.
Heat conduction amount under conditions of embodiment in the method using system described herein can be through being determined by the following.Firstly,
Under the background for carrying out hot enhancing by conduction in such as disclosure, it is necessary to assess gap on the conduction orientation along hot slope
The thermal conductivity of interior gas.High temperature air at or near the surface of the sheet material cooled down, which has, compares Cryogenic air significantly more
High thermal conductivity, the room temperature compared with Cryogenic air such as at spreader surface or near it or close to the air of room temperature
(the nominal thermal conductivity of (dry) air at room temperature (25 DEG C) is about 0.026W/mK).Using the air assumed on entire gap cold
Approximation in two apparent surface's mean temperatures when but starting.In cooling start, building glass piece can be for instance in 670
DEG C temperature, and spreader surface can for example start at 30 DEG C.Therefore, the mean temperature of the air in gap will be 350
DEG C, dry air has the thermal conductivity of about 0.047W/mK at such a temperature;It is higher by 75% or more than its thermal conductivity at room temperature
It and is the sufficiently high gap so as to the size in system through the invention to conduct a large amount of thermal energy, such as following institute
As discussion, it is assumed that sheet material is finish-machined to surface and the consistency of thickness of reasonable altitudes.
In order to illustrate Qcond, i.e., by distance be g gap heat transfer rate conducted component (with the gap
On the vertical direction in the direction of distance g) (area possessed by the gap is Ag) can be given by:
Wherein k is the thermal conductivity of material (gas) in the gap assessed in heat transfer direction (or opposite direction), and Ts is
The temperature of glass surface, and THSIt is the temperature of spreader surface (or being heat source surface in other embodiments).Such as with
On refer to, Due Diligence k will need to merge the thermal conductivity of gas along (or opposition) conduction direction of heat flow, because of gas
Thermal conductivity changes with temperature-but it is used as good approximation, in two surface temperatures Ts and THSAverage value under, k can be with
It is counted as the k value of gas in gap.
As unit of heat transfer coefficient (by hot-fluid power/square metre/Kelvin as unit of) reconfigure equation (14) to
Out:
So the effective heat transfer coefficient across gap conduction is the thermal conductivity of medium in gap (being in this case air)
(as unit of W/mK) is divided by gap length (as unit of rice), to provide the temperature difference as unit of Watt/ square metres/degree

It is not in contact between bearing or is not in contact substantially.Hot-zone 310 has gas bearing 312, supplies from hot-zone pumping chamber 318
To each gas bearing 312, and bearing 312 is used for the cartridge heater 314 in hole is inserted by bearing 312
Hot-zone gas bearing 312 is heated to desired starting process temperature.Building glass piece (hot-zone) 400a is maintained at hot-zone gas
It is long enough to reach desired precooled temperature (for example, being higher than transition temperature) between bearing 312.
In some embodiments, it can mainly be completed by making heat be conducted through thin barrier layer for gases from radiator
Sheet material is heated in hot-zone.The conduction used in hot-zone can be similar with cooling means as described herein, still
