超薄玻璃应力测试及对退火工艺指导
|
摘要
采用美国Hinds公司的Exicor~?GEN5进行超薄玻璃板板芯应力测试,利用测试结果指导超薄浮法玻璃退火工艺参数调整。退火工艺调整前超薄玻璃的南、中、北应力分布不均匀,同一玻璃板面的3个样品,光程差相差较大;退火工艺调整后超薄玻璃的南、中、北应力分布均匀,同一玻璃板面的3个样品应力分布状态基本一致。结果表明:通过测量超薄浮法玻璃板芯应力,分析应力分布状态,对超薄玻璃生产调整退火参数起指导作用。
The stress of ultra-thin glass plate core was test by using Exicor~? GEN5 from Hinds Company of the United States. The test results were used to guide the adjustment of annealing parameters of the ultra-thin float glass. The stress distributions in the south, middle and north areas of the ultra-thin glass were not uniform before the adjustment of annealing process. The three samples from different areas of the same glass plate had a large fluctuation in optical path difference. However, the stress distributions of the south, middle and north area of the ultra-thin glass plate were basically the same after the adjustment of annealing process. The results show that through analysis of the stress distribution status by measuring the core stress of ultra-thin float glass, the guidance of adjustment of annealing parameters in ultra-thin glass production can be achieved.
