浮法超薄玻璃化学钢化及性能研究

Research on Chemical Strengthened of Ultra Thin Glass

本文研究高铝超薄浮法玻璃与浮法钠钙硅玻璃的化学钢化过程。用全自动化学钢化玻璃表面应力测试仪、万能试验机和数显显微维氏硬度计分别测试了样品的表面应力、应力层深度、抗折强度和显微硬度。结果表明:在一定的温度下,随着离子交换时间的增加,高铝超薄玻璃与浮法钠钙硅玻璃的表面应力、抗折强度、显微硬度均出现先增加再到减小的趋势,应力层深度则随着时间的增加而加深。在同样的离子交换制度下,高铝玻璃化学钢化后的力学性能优于钠钙硅玻璃。同时,以浮法工艺生产的玻璃锡面的表面应力小于非锡面的应力,应力层深度也相对小于非锡面的深度。

Chemical strengthened process of ultra-thin aluminum silicate glass and float soda-lime silicate glass were studied in this paper. The strengthened process were characterized by surface stress,depth of stress floor,bending strength and micro-hardness of the samples. The results showed that under certain temperature,with the increasing of ion exchange time,the surface stress,bending strength and microhardness of aluminum silicate glass and float soda-lime silicate glass are first increased and then decreased,while the depth of stress is increased with the increasing ion exchange time. Under the same ion exchange condition,the mechanical properties of aluminum silicate glass are superior to that of sodalime silicate glass. Meanwhile,the stress of the Sn surface is less than that of the non-Sn surface,and the depth of the stress is relatively smaller than the non-Sn surface.
