纸质藏品修复用水考量

本工作借鉴已有的研究成果,并辅以相关调研,试图探究修复用水选择的重要性以及如何选择修复用水的问题。为此,通过对国内外文献的分析以及相关问题的调研,综述了生活饮用水中对纸张长期保存有害的污染物及其对纸张纤维的危害。通过对修复用水实例的讨论,指出:纸质藏品的修复须采用净化水,即通过逆渗透、去离子处理等方法净化后并达到一定电阻率的纯水,在条件许可的情况下,采用电阻率更高的超纯水更好;须现制现用以保证使用过程中净化水不被再次污染;在设备方面,选择小型纯水系统更能保证用水质量。

Consideration of the water used for restoration of paper-based collections

The effects of harmful pollutants in domestic drinking water and their harm to paper fibers, based on the analysis of domestic and foreign literature and related investigations, are summarized. In discussions of the use of water for paper restoration, it is pointed out that purified water (obtained via reverse osmosis and deionization, etc., of sufficiently high resistivity) should be selected for this purpose. It is better to use ultrapure water with higher resistivity where possible. In order to ensure that purified water is not re-contaminated after purification, it should be used right after being made. In terms of equipment, selection of a small pure water system can ensure better water quality.
