| 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. |
