| Summary: | 碩士 === 國立雲林科技大學 === 文化資產維護系碩士班 === 100 === As people get information through computers in this technology fast-growth society, most of the information was gathered into file paper by using 3C products. To meet the demand from enormous users, standard spec of file paper were established for printers, photocopier, and other 3C products. When we used those machines to copy or edit our data, preserve time-limit of file paper or the unique value of those data were never considered as important or essential. We use the same paper for all data, so does our governmental organization.
Due to the reason that people did not choose the right paper and consider the time-limit for preservation, we need to waste more manpower, time and money to manage with the degradation of paper itself. This study applied accelerated degradation test on all paper samples that were found on the market, including those preservation improved paper from domestic and overseas. The color difference, tensile strength and Ph value were evaluated of those papers in this study, and we suggest the most suitable paper for preservation at the conclusion. We hope this study will assist people to choose the suitable paper in the office.
The three key factors of paper degradation are temperature, humidity and luminosity. Due to the restriction of our lab facilities, we only emphasized on temperature and luminosity in this study. The study used two test methods to accelerate thermal dissociation and light induced degradation (LID) with all our sample papers. Through the changing of color light, tensile strength, and Ph value, we know more detailed status of paper degradation process.
The test result showed that MITSUBISHI PPC paper, acid-free paper from U.S., and specialized acid-free paper for preservation in Japan were suitable for long time preservation. We strongly suggest choosing above three types of paper for all the important data / file.
