摘要
利用辐照技术来改善高反射EVA胶膜的性能。使用电子加速器对高反射EVA胶膜进行辐照加工,分析了不同电子束流强度对胶膜预交联度、硫化速率、剥离强度和封装效果的影响。研究结果表明:随着电子束流强度的增加,胶膜的预交联度、硫化速度、剥离强度的衰减程度均不断变大;当束流强度达8 mA时,硫化速率趋于稳定,胶膜封装效果最好。辐照技术的应用,提高了废料利用率,降低了生产成本。
Irradiation techniques are used to improve the performance of high reflective EVA film.High reflective EVA film was irradiated via an electron accelerator.The effects of different electron beam intensity on pre-crosslinking degree,curing rate,peeling strength and encapsulate effects were evaluated.The results show that:as the intensity of the electron beam increased,the pre-crosslinking degree of the film increased continuously;the curing rate increased and tended to be stable when the beam intensity reached 8 mA;the attenuation of peel strength was increasing.When the beam intensity was 8 mA,the film was well encapsulated.The application of irradiation technology has improved the utilization of waste and reduced production costs.
