Embodiment
The present invention is described in further detail below in conjunction with attached drawing.
In the description of the invention, it is to be understood that term " " center ", " on ", " under ", "front", "rear", The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on attached drawing institutes The orientation or position relationship shown, is for only for ease of description the invention and simplifies description, rather than indicates or imply and is signified Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the present invention Limitation.
A kind of tempered glass producing method, comprises the following steps：
Step 1: cutting big sheet glass, the required blank of production of next procedure is cut out, hand can be selected according to the size of glass Work is cut or machine cuts, and the side amount of staying of blank is usually 4-5 times of thickness of glass, and side is broken in favor of surrounding.
Step 2: glass cold treatment, cuts into required shape by blank, the leftover pieces of glass-cutting is got rid of, to glass Polish at the edge of glass fracture.
The too conference of the cutting pressure of numerical control cutting machine causes chip, and pieces of glass bits peel off, and edge of a knife line turns white opaque.Cut Cutter wheel is too sharp, can also cause chip and pieces of glass to consider to be worth doing and peel off.Scribing wheel will be selected according to the thickness of glass, different Thickness uses different break bars.
Scribing wheel must set a suitable height on glass, if cutter head is too high, the edge of a knife will too shallow or root This stroke less than if too low cutting wheel can cause glass breaking when contacting glass, usually adjustment minimum point is from glass 0.3mm.
Need edge ground smooth, glass edging generally using emery wheel edging after glass severing, emery wheel wants root Chosen according to thickness of glass, choose the emery wheel identical with thickness of glass.
In order to eliminate the dust of glass surface, greasy dirt, impurity, it is necessary to carefully wash, glass must dry completely after washing It is dry, during movable glass, it is necessary to take clean gloves, not handy hand directly contacts the glass after washing.
Step 3: surface layer of glass after washing pastes anti-reflection film, it is careful during anti-reflection film to paste, and hand cannot touch glass Surface, cannot have bubble on anti-reflection film, after stickup anti-reflection film compacting flatten.
Step 4: the heating tempering of glass, annealing furnace is heated, tempering temperature is maintained at 650 DEG C -670 DEG C in stove, Glass is entered by transfer roller and heating tempering is carried out in annealing furnace, is 40s-45s per 1mm thickness glass heating times.
Tempering temperature is the important parameter of steel process, it directly affects the intensity of glass, and heating-up temperature is high, and when quenching holds Broken, it is critically important to select rational tempering temperature.Using increasing certain temperature on the basis of glass transition temperature Tg Degree, softening temperature Tg=550 DEG C of general plate glass, to make the performance of anti-reflection film stablize, will not it is burned or thawing, with roller-way Between will not extrude, wind spot will not be produced, tempering temperature increases by 100 DEG C -120 DEG C for softening temperature to be advisable, i.e. tempering temperature Spend for 650 DEG C -670 DEG C, 665 DEG C when can reach best effect.
Specifically, various forms of heating furnaces, because chamber structure is different, the location of instrument of thermometric and its surrounding Situation is also different, and the setting of annealing furnace furnace temperature is generally 50 DEG C -130 DEG C higher than tempering temperature.
Firing rate depends on the setting of heating time and the setting of stove heating power, and firing rate is too fast, in glass The outer temperature difference is too big, and glass surface has softened, and central core does not eliminate also in solid state stress, steel of coming out of the stove when stress does not eliminate Change, at this time can be excessive and broken because of central core tension, if extending heating time again treats that central core softening is come out of the stove again, at this moment Light distortion or deformation, the too slow loss that can cause yield again of heating time setting, therefore every 1mm can occur because superficial layer is too soft Thickness glass heating time is 40s.
The heating tempering stage includes beginning to warm up the stage and continues the heating period, and as shown in Figure 1, tempered glass 4 passes through Roller-way 2 is entered in annealing furnace 1, is entered and is begun to warm up region 11 and carry out beginning to warm up the stage, begin to warm up staged glass by Room temperature, which enters in annealing furnace 1, to be heated, and glass inner layer temperature is low, and exospheric temperature is high, and outer layer starts to expand, and internal layer is unexpanded, outer layer Expansion suppressed surface be subject to internal layer and generate temporary transient compression, central core is tension；Glass, which enters, to be continued to heat Region 12 starts to continue the heating period, continues the heating period glass ectonexine temperature difference and reduces, all reaches tempering temperature to ectonexine When glass in iso-stress；Then glass, which enters, carries out toughening, forming in tempering shaping area 13.
Step 5: the cooling of glass, glass is sent out from annealing furnace 1 by air grid, carries out quenching cooling.
Quenching cooling includes starting the quenching stage and continues the quenching stage, as shown in Figure 1, starts the quenching stage to start The preceding 2s of blowing, glass is continued to be conveyed into air grid 3 by annealing furnace 1 is blowed quenching, into starting quenching region 14, glass Surface temperature descends below central temperature, and superficial layer starts to shrink at, and central core is not shunk, and the contraction of superficial layer receives central core Suppression, superficial layer is subject to of short duration tension, and central core forms compression；It is the preceding 2s-12s for starting blowing to continue the quenching stage Interior, glass, which enters, to be continued to be quenched region 15, and glass ectonexine is further quenched, and surface layer of glass temperature drops to less than 500 DEG C simultaneously Hardening, stops shrinking, and central core begins to cool down, shrinks, and the superficial layer of hardening suppresses the contraction of internal layer, and superficial layer produces pressure should Power, central core form tension.
Continue to complete toughening process, surface layer of glass and the complete tempering of central core, ectonexine temperature after the quenching stage in 20s Difference reduces, and the final stress of tempered glass is formed, and superficial layer is compression, and central core is tension.
Doubling is carried out after 4 toughening process of tempered glass, is set between the shiny surface of the tempered glass 4 after two tempering Doubling layer 41 forms doubling glass, and doubling glass is placed and carries out high-temperature high-voltage reaction in a kettle, reactor temperature is 130 ± 5 DEG C, pressure is 1.25 ± 0.5MPa, and reactor temperature is 130 DEG C in the present invention, pressure 1.25MPa.Such as attached drawing 2 It is shown, doubling glass is placed on during doubling in the plastic foil 5 after doubling, in the opposite plastic foil of doubling glass shiny surface Punched on 5 and place pumping connector 6, its excess-three side of plastic foil 5 seals to form sealing strip 51, and pumping connector 6 connects outer The aspiration pump in portion, is vacuumized in reaction kettle.
