摘要
通过分析离子交换增强玻璃表面K+浓度、表面应力、交换层深度和熔盐成分变化,研究了不同浓度Ca2+对K+-Na+交换的影响以及添加剂对熔盐中杂质离子作用的机理。结果表明:K+-Na+交换速率随熔盐中Ca2+浓度的增加而降低,在失活的熔盐中添加KHCO3可消除Ca2+对K+-Na+交换的不利影响。
Through analyzing the potassium concentration profiles, the surface stress, the exchange layer depth of ion-exchange strengthening glass and the molten salt composition change, the effect of different concentration Ca^2＋on K^＋-Na^＋ ion-exchange as well as additive on the impurity ion were studied. The results show that K^＋-Na^＋ ion-exchange rate decreases as the concentration of impurity ion increases, the detrimental effect on ion-exchange can be re- duced by adding KHCOa in this deactivated molten salt.
