摘　　要：本文主要研究化学钢化玻璃中第一步离子交换的时间对化学钢化玻璃的性能影响。制备出不同的离子交换时间的化学钢化玻璃。分析第一步交换时间对钢化玻璃的弯曲强度、Weibull模数、表面应力大小、深度以及K+离子扩散所产生的影响。结果表明:随着第一步离子交换时间的延长,弯曲强度逐渐降低,Weibull先升高后降低,在40h时达到最高值;表面应力大小会随着时间的延长而降低,应力深度会增加;K+离子扩散曲线符合菲克第二定律的拟合曲线。扩散深度随着时间增加而增加,并且会在玻璃内部产生富集峰。This paper studies the performance effects of the chemical tempered glass by the time in the first step of ion exchange.Different chemical tempered glass with different time in the first step of ion exchange have been made.The effects of bending strength,Weibull modulus,surface stress,stress depth,and K＋ion diffusion by the time have been analysed.The experimental results show that with the extension of the time in the first step of ion exchange,the bending strength decreased gradually.Weibull modulus increased first and then decreased,and the highest Weibull modulus value has appeared when the time of ion exchange is 40 hours;With the extension of the time,surface stress decreased,but stress depth increased;K＋ion diffusion curve fitted the fitting curve of Fick ＇s second law.Diffusion depth increased with the extension of the time,and an enrichment peak would be produced inside the glass.
