摘　　要：档案纸张间的酸迁移,会导致无酸纸酸性逐渐增强,理论与实践早已认识这一现象,但关于酸迁移的机理及其影响因素至今未做研究。本文采用干热老化实验和湿热老化实验,研究酸迁移的一般特征,发现纸张中的酸会随着时间的推进而愈发向另一纸上迁移,迁移受到纸张种类等因素影响;在相同温湿度环境中,手工纸对于H+的吸附能力强于机制纸。在对老化后中性纸红外谱图的对比研究中发现,酸迁移还表现在会直接导致纸张泛黄,这一研究结论进一步证实档案使用无酸纸张、卷皮盒的重要性。It has been acknowledged that the acid migration between archive papers will increasingly intensify the acidification of the acid-free paper theoretically and practically. However the mechanism of acid migration and its impacting factors have been unexplored. This paper proves the universality of acid migration and finds out its characteristics on the aged paper by simulating the naturally aging environment based on the dry-heat aging experiment and the moist-heat aging experiment. Discoveries have been made that the acid in one paper gradually migrates to others and this process is affected by several factors, such as humidity, temperature and type of paper. Specifically hand-made paper shows stronger adorability than machine-made paper with the same pre-set temperature and humidity. Besides, this paper indicates in the comparative research of infrared spectrum of neutralized paper after aging that acid migration leads to yellowing of paper and it then strengthens the necessity of free-acid paper and box.
