摘　　要：纸质档案文献酸化不利于字迹的耐久性,会造成字迹模糊、褪色和变色等问题,影响信息内容的识别和阅读,进而影响档案文献的寿命。本文研究了非水相纳米MgO脱酸技术在脱酸过程中对蓝黑墨水、喷墨打印墨水、原子印章三种常用档案字迹材料的影响。运用能量色散X射线谱(EDS)对三种字迹材料的主要元素成分进行检测分析,并通过pH、相容性、色度、字迹耐久性等实验测试,发现该脱酸剂能有效提高档案字迹的pH值;不会造成字迹模糊、晕染或扩散等现象;字迹表面会附着少量白色沉淀颗粒物。脱酸处理对蓝黑墨水字迹和原子印章字迹无明显不良影响,且一定程度上提高了其耐久性;而对喷墨打印墨水字迹有一定程度的不利影响。Acidification of paper archives is not conducive to the durability of handwriting,which can cause problems such as illegible,fading and discoloration,doing damage to identifying and reading information content,and the lifespan of archives further.In this paper,the effects of non-aqueous MgO nanoparticles deacidification technology on three common archival handwriting materials-blue black ink,printing ink and atomic ink,whose main elements were analyzed by X-ray Energy Dispersive Spectroscopy(EDS)were studied.What’s more,through the experimental tests such as pH,compatibility,colorimetry,and durability of handwriting,it was found that the deacidification agent can effectively improve the pH value of archival writing and reduce the degree of acid hydrolysis of the writing;and it will not cause blur,bleeding or diffusion.A small amount of white precipitation adheres to the surface of the handwriting.The deacidification treatment has no obvious adverse effects on the blue black ink writing and atomic ink writing,and the durability is improved to some extent;while producing a certain degree of adverse effect on the printing ink writing.
