Embodiment 1
[0017] The invention provides a technical solution: a tempered glass processing technology, which mainly includes the following steps:
[0018] A. Clean the glass surface: Use a decontamination cleaner to decontaminate the glass surface, and dry the glass surface after decontamination cleaning;
[0019] B. Preheating the glass: push the glass horizontally into the tempering furnace, and inject nitrogen gas to slowly heat the tempering furnace, so that the temperature of the glass surface rises from room temperature to 180°C, then keep the temperature for 2 minutes, and turn off the nitrogen gas;
[0020] C. Spray a layer of silica powder on the surface of the glass: pull the glass out of the tempering furnace, spray a layer of silica powder with a diameter of 0.6 microns on the surface, and then push the glass into the tempering furnace;
[0021] D. Heating the glass with high power: Slowly raise the temperature of the tempering furnace to 650°C, inject nitrogen gas during the...
