不同浓度硫酸对纸张老化性能影响的初步研究
A Preliminary Study on the Effect of Different Concentrations of Sulfuric Acid on the Aging Properties of Paper
摘要
Abstract
Acidic substances such as sulfuric acid,which is contained in writing materials,is one of the important factors causing paper aging.Xuan paper,edging paper and newspaper were soaked in 2％,4％,6％,8％and 10％sulfuric acid for 10 days in this study.The properties of the color difference,tensile strength and micro structure of fibers were tested respectively.The results showed that the L value which expresses light-shade of the three kinds of paper decreased,with the increase of sulfuric acid concentration,the color of the paper gradually darkened.Simultaneously,the a value which indicates yellow-green gradually increased,the color became more yellow.The total color difference △E increased,the color change was obvious.The maximum tensile strength also decreased with the increase of sulfuric acid concentration.The paper fiber was broken and shortened under the action of sulfuric acid,the higher the concentration of sulfuric acid was,the shorter the fiber was broken.The aging and deterioration of papers in acidic environment has induced the destruction of the cultural heritage value and literature value.关键词
