摘要
在锡槽内采用不同氢气与氮气比率的保护气体,探究保护气体中氢气与氮气比率对浮法玻璃生产过程中的高铝玻璃发朦的影响。利用SEM-EDS、分光光度计、光泽度仪、X射线能谱对样品进行表征并分析浮法玻璃生产过程中发朦的原因,并对发朦问题进行解决。结果表明:锡槽内氢气含量过高或者氢气与氮气的比值较高时,会出现玻璃发朦现象。其主要原因是氧化锡被保护气体中的氢气还原,形成单质锡并滞留在玻璃上表面,造成玻璃表面发朦,玻璃上表面光泽度降低。通过调整锡槽保护气体中氢气的用量和比例,可以有效解决浮法生产线中玻璃发朦的问题。
The influence of the ratio of hydrogen to nitrogen in the protective gas on the haze of high alumina glass in the production process of float glass was studied by using different hydrogen and nitrogen ratios in the tin bath.The samples were characterized by SEM-EDS,spectrophotometer,glossiness meter and X-ray energy spectrum,and the causes of the haze in the float glass production process were analyzed,and countermeasure was proposed.The results show that when the content of hydrogen in the tin bath is too high or the ratio of hydrogen to nitrogen is high,the glass will appear haze.The main reason is that tin oxide will be reduced by hydrogen in the protective gas to form metallic tin and stay on the upper surface of the glass,resulting in haze on the glass surface and reducing the glossiness of the upper surface of the glass.By adjusting the content of hydrogen gas or the ratio of hydrogen to nitrogen,the haze problem can be effectively solved.
