近现代文献脱酸关键技术集成与应用

Integration and application of key technologies for deacidification of neoteric and modern literature

为解决纸质文献酸化的问题,针对近现代文献存世量大、保存状况差、酸化严重的现象,对已有脱酸技术进行优化,实现了水溶液脱酸-微波干燥-冷冻干燥的规模化集成。每批次的脱酸处理量不少于30本图书,脱酸后图书pH值和碱储量均有提高,皱缩率可控。初步构建起规模化脱酸示范技术体系,并进行集成应用示范,为大量近现代文献的保护提供技术支撑。

Considering the huge quantity, poor storage conditions and severe acidification of neoteric and modern paper literature in China, we sought to optimize the existing deacidification technologies of Nanjing Museum, and to integrate aquatic solution deacidification, microwave drying and freeze-drying technologies massively. At least 30 books were deacidified in each batch. After deacidification, the pH values and alkaline reserves were both improved and the paper shrinkage rate was controllable. A preliminary system that incorporates both the technology and demonstration of it for massive deacidification has been created in order to provide technical support for the conservation of the huge amount of neoteric and modern paper literature.
