浮法玻璃在线阳光镀膜生产中针孔缺陷产生原因分析及解决措施

Analysis on Causes and Solutions of Pinhole Defects in the On-line Solar-control Coating Production on Float Glass Surface

分析了导致在线阳光镀膜玻璃产生针孔的原因。其中锡槽污染是最主要的原因,要通过多种方式减少硫化亚锡和氧化亚锡的产生;此外,镀膜工艺及设备也是产生针孔的主要原因之一。要严格按操作规程执行,以提高镀膜质量。

The causes of pinholes in the online solar-control coated glass were analyzed,among which the pollution in tin bath was the main reason.Reducing formation of stannous sulfide and stannous oxide can be achieved in a number of ways.In addition,the coating process and equipment are also one of the main causes of pinhole defects.The operation procedures must be strictly followed so as to improve the coated quality。
