摘要:为研究档案灭菌杀虫方法对纸张物理性能强度指标是否有影响,方法一分别将装有1950年出版旧书刊纸、1987年出版旧书刊纸、1988年出版旧书刊纸、静电复印纸的标准档案盒置于喷洒过量油樟生物复合剂的密闭空间内密闭7天；方法二将四种纸样分别置于零下20℃冷冻10天,零下50℃冷冻24小时。处理后测定纸样的抗张强度、裂断长、伸长率、耐折强度、撕裂强度和耐破强度,与空白组纸样比较。结果表明：两种灭菌杀虫方法处理过的纸样物理性能强度指标与空白组相比变化不明显,说明两种灭菌杀虫方法对档案纸张物理性能无显著影响。

Abstract:In order to investigate whether the sterilization and insecticidal methods of archives have an impact on the physical properties and strength indicators of paper, Method 1 placed standard archive boxes containing 1950 published old book and magazine paper, 1987 published old book and magazine paper, 1988 published old book and magazine paper, and electrostatic photocopy paper in a sealed space sprayed with excessive camphor bio compound for 7 days; Method 2: Freeze the four types of paper samples at -20 ℃ for 10 days and -50 ℃ for 24 hours. Measure the tensile strength, fracture length, elongation, tear strength, burst strength, and flexural strength of the processed paper sample, and compare it with the blank group paper sample. The results showed that the physical properties and strength indicators of the paper samples treated with the two sterilization and insecticidal methods did not change significantly compared to the blank group, indicating that the two sterilization and insecticidal methods had no significant effect on the physical properties of archival paper.
