清代圣旨字迹显现研究

摘要

圣旨是研究当时社会政治、经济和文化等的珍贵资料。圣旨中的字迹在长期的储存过程中褪色淡化,导致历史信息消失而失去相应的价值。对圣旨褪色的成因进行分析,进而采用显现剂纳米二氧化硅/正丁醇分散液对字迹进行显现。采用红外光谱、扫描电镜和视频接触角考察显现剂对模拟样的影响;通过色差和力学性能评价显现剂对模拟样耐老化性能的影响。结果表明,显现剂能清晰地显现模糊不清的字迹而未明显改变圣旨的形貌和组成结构;提高了圣旨基材的力学性能和耐老化性能,对圣旨的长久保存具有重要意义。该方法对同类型的字迹显现具有一定的借鉴作用。

Abstract

Imperial edict is a precious information for the study of social politics, economy and culture at the corresponding time. The handwriting in the imperial edict has faded down in the process of long-term storage, which leads to the losing of its valuable information. In this paper, the cause of fading of handwriting on the imperial edict was firstly analyzed, then, the handwriting reappeared under the action of a dispersion agent of nano-silicon dioxide/n-butyl alcohol. The influence of reappearance reagent on the simulate sample was investigated using infrared spectrum, scanning electron microscopy and video contact angle. In addition, the effect of reappearance reagent on the ageing resistance was evaluated by color difference and mechanical performance of simulate sample. The results showed that the reappearance reagent not only visualized the vague handwriting without significantly changing the morphology and structure of the imperial edict, but also improved the mechanical properties and ageing-resistant performances of imperial edict, which is of great significance to saving the imperial edict for a long time. The method has a certain reference to the visualizing of the fade handwriting on similar cultural relic.
