Embodiment 1
[0046] Use the following weight percentage components: 60% SiO 2 ;14%Al 2 o 3;3.5%B 2 o 3 ;5%MgO;5%BaO;11%CaO;1%ZrO 2 and 0.5% Sb 2 o 3 Made of high-quality glass, the size is 130×26×19mm, all surfaces are polished, and there are no defects such as bubbles, streaks and stones inside.
[0047] Put the processed glass into the heating furnace, raise the temperature to 900°C at a heating rate of 5°C / min, keep it warm for 30 hours for microcrystallization treatment, then raise the heating furnace to 940°C at a heating rate of 10°C / min, and hold it for 10 minutes , quickly move the glass out of the heating furnace, put it on the support in the wind field for horizontal rotation and cooling, the rotation speed is 80rpm, the wind pressure is 0.12MPa, and the glass is taken out of the wind field after 4min. Apparent quality testing shows that the tempered glass has no deformation in appearance, and the apparent quality is good. After testing, the bending strength of the glass ...
