对位芳纶纸在湿纸页成形后需要热压处理来提升其性能。本文研究了对位芳纶纸热压后纸页各项性能的变化以及热压过程中产生的各种现象并提出了改善方法;同时,借助扫描电子显微镜(SEM)研究了热压后纸页表面纤维结合状态和纸页横截面的微观结构。
Para-aramid papers require hot pressing after wet sheet formation to improve their properties. In this paper, we studied the changes of paper properties after hot pressing of para-aramid paper and the various phenomena produced during the hot-pressing process and put forward the improvement methods. At the same time, we studied the hot-pressed paper with scanning electron microscopy (SEM) Surface fiber bonding state and paper sheet cross-section of the microstructure.
