| Summary: | 碩士 === 國立雲林科技大學 === 文化資產維護系碩士班 === 92 === Paper, the carrier of civilization, communicates culture, art, knowledge and memories. As recent development of technology progresses rapidly, part of paper’s function seem to have been replaced by digital techniques. However, “image” still can not replace the texture and sentimental value of paper. The study of paper deterioration is inclusive of multiple aspects, such as the texture of paper, papermaking materials and methods, preservation environment, and restoration materials and methods. The multitude of inner and surface factors and deteriorating factors involved in paper deterioration process demonstrate the magnitude of complexity of a paper degradation study.
Preventive conservation is the consensus reached by worldwide conservation scientists. The research addressing the preservation environment of wood-based panels is used in this article to discuss how the mechanics, color and pH value of paper changes when stored in VOC environment. The experiment started by establishing and evaluating the pH value indicator test for paper, followed by executing paper pH value indicator test using cold -water extraction method to achieve a more stable enumeration environment. The exposure test utilized chambers build with ten different kinds of wood-based panels to preserve five kinds of industrial paper each with different settling time. Then the tensile strength, color-difference and pH values are measured for the correlation of paper degradation and wood-based panel materials after exposure. During the process, Oddy test was also performed to evaluate suitability of the ten different materials used in the experiment.
Following chamber exposure test, accelerated aging was also performed to investigate whether short-term exposure under wood-based panel environment can accelerate paper deterioration process.
The experimental results of exposure test shows the three trends of changing pH value, mechanics and ADMI for paper being exposed in wood-based panels for a short time. The experimental result of Oddy test also demonstrates the possible risks of using the ten materials in the experiment as art treasure exhibition and storage equipment.
This study discusses in depth the three paper degradation indicator tests which can serve as references and guidelines for culture heritage organizations when choosing exhibition and storage equipments.
