玻璃的膨胀系数对玻璃退火指导意义探索

Exploration on the Guiding Significance of Expansion Coefficient of Glass For Glass Annealing

简要介绍了热膨胀系数与热历史的关系。通过对普通玻璃、超薄玻璃以及炸板玻璃热膨胀系数的测试,分析比较玻璃板热膨胀系数的差异,得出玻璃正常生产时热膨胀系数曲线的分布状态,对玻璃生产退火工艺制度的调整有重要意义。

The relationship between thermal expansion coefficient and thermal history is briefly introduced.The thermal expansion coefficient of ordinary glass,ultra-thin glass and Fried glass is tested,and the distribution state of thermal expansion curve of glass during normal production is obtained by analyzing the difference of thermal expansion coefficient of glass,which is of great significance to the adjustment of glass annealing process.
