Type of heating when low temperature should be taked long for three silver medal LOW-E glass tempering process.The parameter that during production, tempering is arranged all answers specification effectively in formulation parameter area, significantly can not change tempering parameters.The quality of product can be made to reach stability during such batch production.
Heating temperature in the optical skew of three silver medal LOW-E and stove, heat-up time, convection flow fan frequency are closely bound up, should find the regulation range of oneself during tempering according to the characteristic of equipment, assembling and experience.
When arranging Heating temperature, consider that three silver medal LOW-E rete faces are different from the heat absorption speed of glass surface, upper and lower part temperature all can not be too high, on simple two room, convection furnace preheating oven temperature is arranged on 350 DEG C ~ 450 DEG C, furnace temp is arranged on 650 DEG C ~ 680 DEG C, and the too high meeting of upper temp causes rete oxidation, variable color.If when three silver medal glass after inspection tempering find the overall variable color of LOW-E or edge generation variable color defect, can judge that Heating temperature is too high, upper furnace body temperature should be reduced and shorten heat-up time simultaneously.
Because the warpage of sheet glass makes the gravity of monolithic glass plate concentrate on crevice middle bottom it when three silver medal LOW-E glass heat in stove, sheet glass is in stove during to-and-fro movement, this part and live roll friction, that surface physics scratches, produce white opacity, time serious, may viscous deformation be produced.The face of LOW-E glass contact roller-way there is roller-way print (vaporific in vain), lower furnace body temperature should be reduced.
Heat-up time and Heating temperature are mutually mated, and it is inadvisable that high temperature, short time produces three silver medal LOW-E glass events, is the optimal selection mode of processing three silver medal LOW-E when low temperature is long.
Under the prerequisite that temperature sets, judge according to the optical skew degree after three silver medal LOW-E tempering and adjust heat-up time, long meeting heat-up time causes three silver medal LOW-E surface optical distortion, the control of optical skew can refer to tempering zebra stripes, the optical skew of edge 100mm must control lower than one bending deformation, and middle part zebra stripes must be straight.
The convection flow fan that annealing furnace is equipped with has a great impact three silver medal glass temperatures, and correct selected process operation parameter obtains the temperature required guarantee of accurate glass.The convection current frequency of convection furnace top convection flow fan answers 100% to open foot at preheating section, and arranging frequency is 60Hz, and in convection tempering furnace, glass preheats by convection current, and rete is absorbed heat evenly in preheating oven, sends into second room after reaching pre-heat effect.Convection flow fan set of frequency should be arranged according to section heat-up time, first section convection current frequency should be 60Hz, stage casing convection current frequency should be 40 ~ 50Hz, latter end convection current frequency should be 30Hz, it is because be equivalent to actual temperature when glass reaches softening temperature at about 660 DEG C that latter end falls low, convection flow fan is now only and keeps in-furnace temperature to be main, mode when what tempering three silver medal LOW-E own taked is exactly low temperature is long, it is too fast that second half section too high convection flow fan frequency can make temperature rise, and after making glass tempering, optical skew increases the weight of.The Heating temperature of mutual coupling, heat-up time, convection flow fan frequency just can produce high-quality three silver medal LOW-E glass.
Three silver medal toughened glass meet related fragment and requirement of strength, and compared with the white glass of stack pile float glass process, tempering blast will increase 10 ~ 20%, and set Heating temperature, heat-up time break to avoiding blowing cooling air section at air grid just.And stress and the fragment requirement of toughened glass must be met simultaneously.
Modification method is adjusted according to three silver medal LOW-E quality conditions after tempering, three silver medal LOW-E glass because of when coming out of the stove inlet grid cooling bottom glass face radiating rate faster than three silver medal LOW-E rete faces, so the LOW-E glass after tempering very easily upwarps, therefore first should consider this point when arranging air balance, wind should be put down 1/2nd point values arranging and orientate as and increase the white glass of common float glass process.
Air grid folding is decided by the fragment of toughened glass and the important factor of intensity, and air grid folding value also can affect the sinuousness of toughened glass.Three silver medal LOW-E windshield mold for toughing foldings can qualitatively be the folding value of common float glass.Control air grid folding by encoder, adjustment air grid air output, improves cooling efficiency.
Adopt convective heating mode can improve the heat transfer conditions of LOW-E glass in tempering heat-processed significantly, because LOW-E glass is in whole heat-processed, the upper and lower surface temperature difference is large, upper surface convection current mainly plays enhance heat transfer effect, the most outstanding feature of these heating means greatly to be shortened the heat-up time to tempering temperature glass heats, and temperature consistency is good.
