Embodiment 1
[0018] Wash and dry the ultra-thin glass of 1.5×212×376mm, and put it into the reaction chamber. After the trimethylaluminum gas is pumped into the reaction chamber for about 1.5 seconds, the pressure of trimethylaluminum in the reaction chamber reaches 600Pa, and then pumps in water vapor for about 1.5 seconds, so that the water vapor pressure in the reaction chamber reaches 800Pa, and then the unreacted gas and The gas produced by the reaction is pumped away, so that the pressure of the reaction chamber returns to 300Pa, and the next cycle of deposition is carried out. A total of 2 cycles are carried out to obtain strengthened ultra-thin glass. After testing, the static compressive strength of the glass before treatment is 1.2kPa, and the static compressive strength after treatment is 1.8kPa.
Embodiment 2
[0020] Wash and dry the ultra-thin glass of 1.5×212×376mm, and put it into the reaction chamber. After the trimethylaluminum gas is pumped into the reaction chamber with a pulse frequency of 80Hz for 1.5 seconds, the pressure of trimethylaluminum in the reaction chamber reaches 800Pa, and then water vapor is pumped in at a pulse frequency of 50Hz for about 1.5 seconds, so that the water vapor pressure in the reaction chamber reaches 800Pa. Then the unreacted gas and the gas produced by the reaction are pumped away, the pressure of the reaction chamber is returned to 600Pa, and the deposition of the next cycle is carried out, and a total of 3 cycles are carried out. After testing, the static compressive strength of the glass before treatment is 1.2kPa, and the static compressive strength after treatment is 2.2kPa.
Embodiment 3
[0022] Clean and dry the ultra-thin glass of 1.7×710×1262mm, put it into the reaction chamber, the vacuum degree of the reaction chamber is 500Pa, the temperature is 250℃, and the trimethylaluminum and the water with the resistivity of 15MΩ·cm are respectively vaporized, After pumping trimethylaluminum gas into the reaction chamber with a pulse frequency of 60Hz for 1.5 seconds, the pressure of trimethylaluminum in the reaction chamber reaches 800Pa, and then pumps water vapor with a pulse frequency of 50Hz for 1.5 seconds, so that the water vapor pressure in the reaction chamber reaches 1000Pa. Then the unreacted gas and the gas produced by the reaction are pumped away, and the pressure of the reaction chamber is returned to 500Pa, and the next cycle of deposition is performed, and a total of 2 cycles are performed. After testing, the static compressive strength of glass before treatment is 1.4kPa, and the static compressive strength after treatment is 1.9kPa.
