Brief description of the drawings
Fig. 1 is the explosion-proof super thick cover-plate glass preparation method's of preferred embodiments of the present invention flow chart.
Detailed description of the invention
In order more clearly to understand technology contents of the present invention, describe in detail especially exemplified by following examples. Ying LiSeparate, embodiment is only for the present invention is described, instead of limitation of the present invention.
Please refer to Fig. 1, is the explosion-proof super thick cover-plate glass preparation method's of preferred embodiments of the present invention flow chart.
S101, enters annealing furnace heating by original sheet glass by room temperature.
Particularly, because glass is hot non-conductor, now glass surface temperature is high, and its superficies startExpand, and inside glass does not expand, the expansion of superficies is subject to inner inhibition, thereby at superficiesProduced temporary transient compression, inside is tensile stress. Because the compression strength of glass is high, even if Fast Heating,Original sheet glass is not broken yet.
Further, the tensile stress of glass and compression are 0.
Further, the thickness of original sheet glass is 6mm.
S102, continues heating glass, glass outer layer surface and the inner temperature difference is locked gradually little, until glassIso-stress in superficies and the inner glass plate that all reaches tempering temperature.
Further, the temperature difference between superficies and inside is progressively dwindled, the tensile stress of glass and compressionBe 0.
S103, carries out quenching processing for the first time to glass.
Particularly, in front 1.5-2 second of blowing, glass is entered to air grid by annealing furnace and blows starting,So that the superficies temperature of glass decline and lower than central temperature, thereby superficies start shrink. Due to interiorPortion does not shrink, thereby the contraction of superficies is subject to inner inhibition, makes to show superficies and is subject to temporarily opening and answeringPower, central core forms compression.
Further, superficies are cooling fast, and temperature is low, and inside is also in high temperature, outer tensile stress andInternal compressive stress is 0.
S104, carries out quenching processing for the second time to glass.
Particularly, glass is further carried out to quenching processing, thus the further quenching of inside glass, now glassSuperficies harden, and reach 500 DEG C, and glass stops shrinking, and inside also begins to cool down, shrinks.Owing to having suppressed inner contraction in the superficies of hardening phase, superficies are produced answer pressure, andFormed a pressure in inside.
Further, superficies and inner temperature reduce, and the temperature difference reduces, thereby inside starts to shrink, outerThe temperature on layer surface is below 500 DEG C, makes superficies occur compression.
S105, continues glass to carry out quenching processing.
Particularly, in 12 seconds, glass is proceeded to quenching processing, the superficies of glass and insideTemperature further reduces, and the inside of glass now drops to below 500 DEG C.
S106, forms toughened glass panel.
Particularly, in 20 seconds, the rear complete tempering of glass, superficies and inner temperature difference are processed in quenchingDwindle, thereby the final stress of safety glass forms, outer surface is compression, and internal layer is tensile stress.
Further, superficies and inner temperature decline, and temperature difference trend balance forms ectonexine and forever shouldPower.
In use, at the nanometer film circuit of the surface printing 0.05mm of the toughened glass panel of 6mm, with shouldFor touch-control desktop, thereby solve the interference that split screen touches.
Explosion-proof super thick cover-plate glass in the present embodiment is applied to touch-control desktop, not only can reach touch screen surfaceAntifouling, uprising, waterproof, outside corrosion-resistant effect, can also solve and drive between multi-screen simultaneously in conjunction with split screen technologyInterference phenomenon. And explosion-proof super thick cover-plate glass has dustproof, waterproof, the effect ability of IP67, this standard to describeThe system that electrical equipment shell protection grade is classified. Carried by Comite Europeen de Normalisation ElectrotechniqueGo out, electrical equipment shell protection grade is divided into a lot of classes, according to different numbers, can facilitate really rapidlyThe degree of protection of fixed output quota product. From material, high strength cover-plate glass kind difference, effect difference. Existing steelChange glass and claim again tempered glass. It is that on glass surface, forming a pressure should by method physics or chemistryPower layer, glass itself has higher compression strength, can not damage. In the time that glass is subject to External Force Acting,This shell of compression can be offset part tension, avoids the cracked of glass, although safety glass inside is in largerTensile stress state, but the inside zero defect of glass exists, and can not make and become to destroy, thereby reach raising glassThe object of intensity. From structure aspects, adopt the flexible material such as rubber around product or other position reinforces,Utilize outside complete machine structure to adjust simultaneously, improve product shock resistance.
Compared with prior art, explosion-proof super thick cover-plate glass preparation method of the present invention, preparation process is simple, knotThe spies such as structure is stable, makes touch-control desktop possess waterproof, antifouling, uprising, resistance to chemical attack, high temperature resistant, and the life-span is longWhen point, can, in conjunction with split screen technology, solve the interference that split screen touches, improve user's experience.
The present invention is not limited to above-described embodiment, but covers the feelings that do not depart from the spirit and scope of the present inventionThe institute carrying out under condition changes and revises. These changes and amendment should not be considered to depart from essence of the present inventionGod and scope, and all amendments such as it will be apparent to those skilled in the art that all should be included inIn the scope of claims.
