油渍对手工纸的耐久性影响研究

油渍是一种纸张上的常见病害，以往对于这种病害如何影响手工纸性能的研究较少。本工作以纸张耐久性变化的研究作为切入点，辅以扫描电镜对油渍与纸张的共存状态的观察，以此来探讨油渍对手工纸的影响。研究表明油渍使得纸张的抗张强度、撕裂度、耐折度等物理性能有一定的降低，色差值增大，pH值降低，油渍以一种物理吸附的作用包裹于纤维之上对纸张造成影响。随着老化时间的增加，油渍因为氧化酸败作用而逐渐变质，从实验结果中发现油渍对纸张的耐久性影响在老化前期影响较大，后期影响较小。

Influence of oil stains on the durability of handmade paper

Oil stains on handmade paper is a common disease of paper relics, but there is little research on how this disease affects the permanence of handmade paper. In this study, the change in paper durability was taken as the breakthrough point, and the coexistence of oil stains and paper was observed by scanning electron microscopy, so as to determine the influence of oil stains on handmade paper. The results show that oil stains can affect the physical properties of paper to a certain extent, increase the color difference values and decrease the pH values. Moreover, oil stains wrapped on fibers to affect the paper in a way of physical adsorption. With the increase of aging time, oil stains gradually deteriorated because of oxidation and decay, so the influence of oil stains on the durability of paper is greater in the early stage than in the later stage of aging.
