离子交换工艺对ESP玻璃的影响
Effect of Ion Exchange Process on ESP Glass
摘要
Abstract
Two step ion-exchanged method for preparing engineered stress profile glass ( ESP glass ) is used in this paper. The first step ion-exchanged time is longer than the second step ion-exchanged time in the two step ion-exchanged method. The difference in the performance of ESP glass after different first step ion-exchanged process is studied. In this paper, the ESP glass is tested by the bending strength test, micro hardness test, EPMA test. Weibull modulus could be calculated by the bending strength, and the ion diffusion coefficient could be calculated by the K ion distribution. The results show:the second step ion-exchanged could reduce the bending strength of the first step ion-exchanged glass. But after the two step ion-exchanged process, ESP glass has a higher Weibull modulus. The trend of micro hardness is consistent with the trend of bending strength. Combined with the bending strength and K ion distribution, the best temperature of the first step ion-exchanged is 450℃, and the time is 30 h. The second step ion-exchanged temperature is 400 ℃, and the time is 33 min.关键词
