【摘要】 本文研究了离子交换温度、时间和加速剂对钠钙硅酸盐超薄玻璃力学性能的影响,发现提高离子交换温度和延长离子交换时间都会导致玻璃的表面应力、抗折强度和表面硬度先增加后降低。最佳的离子交换工艺为450℃,保温10 h,此时超薄玻璃的表面应力、抗折强度和表面硬度分别为552.8MPa,320.1MPa和550.3Kg mm^-2。抗折强度和显微硬度分别是超薄玻璃原片的3.7倍和1.2倍。在KN03中添加加速剂KOH对提高玻璃的力学性能没有帮助,但可有效缩短离子交换时间。更多还原

【Abstract】 This paper studied the influences of ion-exchanged temperature and duration and accelerating agent on the mechanical properties of ultra-thin plate glasses.The results indicate that the surface stress,surface hardness and rupture strength all increase firstly and decrease with increasing the ion-exchanged temperature and extending the ion-exchanged period.The best ion-exchanged processes are 450 ℃ for 10 h,at which the sample has a rupture strength of 320.1MPa and a surface hardness of 550.3Kg mm^-2.The rupture strength and surface hardness of the chemically-strengthened glass are 3.7 times and 1.2 times as large as the original ultra-thin glass.The accelerating agent KOH added in KNO₃ has hardly influence on the mechanical properties besides shortening the ion-exchanged period.更多还原
