摘要:
超薄玻璃的边部由于其形状和厚度的特殊性,对精密退火造成一定的影响,对该处应力控制不利可能会出现玻璃在掰边时不整齐甚至炸板的现象。不同厚度的平板玻璃在成形过程中会形成不同形状和厚度的边部,在一定的退火条件下会在玻璃板平面和边部端面有不同的温度和应力分布。而且同一板面及边部在不同的退火条件下,其应力分布与退火条件存在对应关系。本项工作利用ANSYS建立超薄玻璃的模型,模拟在不同的退火条件下的温度场和应力场,详细分析了退火条件对超薄玻璃永久应力的影响及相互关系。本项工作为超薄玻璃精密退火过程中的应力控制提供了科学的理论依据和指导。
Abstract:
The process of precision annealing can be affected by the special shape and thickness of ultra-thin glass edge.If the stress of this place is not be effectively modulate,there is a phenomenon of the plate glass is irregular and even crack when cutting the edge.Different shape and thickness of the edge of the plate glass with different thickness will be formed in the process of forming,which has different temperature and stress distribution in the edge and plate plane of ultra-thin glass during annealing.There exists a correspondence relationship between stress distribution and annealing conditions in the same edge and plate plane under different annealing conditions.The temperature field and stress field of ultra-thin glass plate under different annealing conditions are established by ANSYS.Analysis how the annealing condition affects permanent stress of ultra-thin glass and the relationship between them.This work provides a scientific theoretical basis and guidance for the stress control precision of ultra-thin glass during annealing process.
