Title
(EN) Chemically reinforced glass and method for production thereof
(ZH) 化学强化玻璃及其制造方法
Abstract
(EN) The invention relates to a chemically reinforced glass having a compressive stress layer formed in the surface layer thereof by ion exchange, characterized in that it has two types of compressive stress curves in the compressive stress layer: an A curve present nearer to the surface of the glass, and a B curve present in the side of an inner layer of the glass; a first method and a second method for producing the chemically reinforced glass: a fist method, wherein, after the immersion treatment for ion exchange, a second immersion treatment is carried out at a temperature higher than that for the previous immersion treatment by 20 to 50 DEG C for 10 to 60 minutes, and a second method, wherein, after a first immersion treatment for ion exchange, a second immersion treatment is carried out at a temperature higher than that for the first immersion treatment by 20 to 50 DEG C for 10 to 60 minutes.
(ZH)

本发明涉及在通过离子交换在玻璃表层形成压缩应力层的化学强化玻璃中,在压缩应力层之中有靠近玻璃表面的压缩应力曲线A与玻璃内层侧的压缩应力曲线B的两种不同应力曲线的化学强化玻璃。该玻璃可采用第1或第2方法制造。第1方法中,在离子交换用的浸渍处理后在比该浸渍液温度高20℃~50℃的温度下进行10分钟~60分钟的第2浸渍处理。第2方法中,在离子交换用的第1浸渍处理后在比该浸渍液温度高20℃~50℃的温度下进行10分钟~60分钟的第2浸渍处理。
