摘要
通过分析真空充氮条件下杀死档案害虫烟草甲全虫态的有效作用时间及其对档案纸张的物理性能的影响,明确了在能够有效杀死害虫前提下,对档案纸张影响最小的真空充氮保压时间。结果表明,真空充氮保压处理60h可有效杀死烟草甲的全虫态。通过比较真空充氮60h处理条件下的宣纸、皮纸、打印纸、新书纸、旧书纸和新闻纸的物理性能,发现处理前后纸张的白度、耐破指数、撕裂指数和抗张指数的差异均不显著,随着存放时间的增长,这些性能变化趋于稳定,说明真空充氮对纸张机械性能的影响不大。
By analyzing the time needed to kill all life stages of L.serricorne,a kind of archival insect,under vacuum nitrogen conditions and evaluating the effect on the physical properties of archival paper,the study determines the optimal duration for vacuum nitrogen filling and pressure holding that ensures insecticidal efficacy while causing minimal impact on archival paper.Results show that a vacuum nitrogen filling and pressure holding time of 60 hours effectively kills L.serricorne of all developmental stages.By comparing the physical properties of various paper types—Xuan paper,leather paper,printing paper,new book paper,old book paper,and newsprint—before and after vacuum nitrogen filling for 60 hours,it is found that there are no significant differences in whiteness,bursting strength,tearing resistance,or tensile strength.Furthermore,these property changes tend to be stabilized over time,indicating little impact of the vacuum nitrogen filling on paper mechanical properties.
