摘　　要：通过对PET片材水浸泡液紫外吸收强度的研究,探讨了在波长220~360 nm范围内引起浸泡液出现吸收峰的原因。通过对PET片材加工过程的控制和助剂的加入,可以有效地减弱在所关注波长范围内的紫外吸收强度。This article explores the reasons for the appearance of absorption peaks in the soaking solution of PET sheets in the wavelength range of 220 nm~360 nm by studying the UV absorption intensity of the soaking solution.By controlling the processing of PET sheets and adding additives,the UV absorption intensity within the wavelength range of interest can be effectively reduced.

关 键 词：PET片材 紫外吸收强度 乙醛 抗水解
