Embodiment 1
[0046] The glass blank used in this embodiment is Corning 2320 grade glass with a thickness of 1.1mm.
[0047] This embodiment provides a method for preparing 3D glass, the specific steps are as follows:
[0048] (1) Clean the glass blank, and then cut it with a laser cutting edge grinder;
[0049] (2) Place the cut glass blank on the hot bending machine mold (structure such as figure 1 shown) and then raise the temperature to 860°C at a heating rate of 40°C / min, hold the temperature for 100 seconds, and gradually attach the softened glass blank to the mold under the action of gravity (the structure during the softening process and the final structure are as follows figure 2 with image 3 shown);
[0050] (3) After the glass blank is attached to the mold due to gravity, first cool down to 640°C at a cooling rate of 20°C and keep it warm for 50 seconds, then drop to 550°C at 10°C / min, and then cool down at a speed of 30°C / min Cool down to 250°C, and finally use cold wind to ...
Embodiment 2
[0054] The glass blank used in this embodiment is iridescent glass CG01 brand glass with a thickness of 1.3 mm.
[0055] This embodiment provides a method for preparing 3D glass, the specific steps are as follows:
[0056] (1) Clean the glass blank, put it into the etching solution for 3 minutes at 24°C, and wash the polishing solution on the glass on the continuous assembly line at 35°C after taking it out, and finally tear off the acid-resistant film;
[0057] (2) After cleaning the etched glass blank, use the sol-gel method to coat the surface of the glass blank with a coating solution;
[0058] (3) Clean the glass blank after coating and then cut it with a laser cutting edge grinder;
[0059] (4) Place the cut glass blank on the mold of the hot bending machine and then raise the temperature to 800°C at a heating rate of 30°C / min, hold the temperature for 5 seconds, and gradually soften the glass blank to the mold under the action of gravity;
[0060] (5) After the glass ...
Embodiment 3
[0064] The glass blank used in this embodiment is Japan Asahi Glass DT-X brand glass with a thickness of 0.7mm.
[0065] This embodiment provides a method for preparing 3D glass, the specific steps are as follows:
[0066] (1) Clean the glass blank, put it into the etching solution at 18°C for 1min, take it out at 22°C, wash the polishing solution on the glass on a continuous assembly line, and finally tear off the acid-resistant film;
[0067] (2) Clean the etched glass blank and cut it using a laser cutting edger;
[0068] (3) Place the cut glass blank on the mold of the hot bending machine, then raise the temperature to 700°C at a heating rate of 40°C / min, hold the temperature for 100 seconds, and gradually soften the glass blank to the mold under the action of gravity;
[0069] (4) After the glass blank is attached to the mold due to gravity, first cool down to 520°C at a cooling rate of 15°C and keep it warm for 300 seconds, then drop to 450°C at 5°C / min, and then cool...
