摘　　要：为了改善浮法电子玻璃表观质量,降低玻璃锡缺陷,提出了一种新的锡槽出口处密封方式——气封,并研究了气体流量、气体压力、气封结构距离玻璃板高度以及出气孔结构对气封效果的影响,获得优化的气封系统参数。结果表明,在一定范围内,气封效果随着气体流量、气体压力的增加而变好,随着气封结构距离玻璃板高度的增加而变差,圆孔结构的气孔优于长条孔结构的气孔。通过优化气封系统,有效提升了浮法电子玻璃的表观质量,降低了玻璃锡缺陷。In order to improve the apparent quality of electronic glass and reduce tin defects in glass,a new sealing method at the outlet of tin bath-gas seal was proposed.The effects of gas flow rate,gas pressure,height of gas seal structure from glass plate and pore structure on gas seal effect were studied respectively,and the parameters of the gas seal system were optimized.It was found that in a certain range,the gas seal effect became better with the increase of gas flow rate and gas pressure,and became worse with the increase of height of gas seal structure from glass plate,and the circular pore structure was better than the long pore structure in the outlet pore structure.The optimization of the gas sealing system effectively improves the apparent quality of float electronic glass and significantly reduces the occurrence of glass tin defects.
