纳米氢氧化钙加固唐墓壁画的实验研究

Experimental Conservation and Consolidation of Tang Murals Using Calcium Hydroxide Nanoparticles

本文采用色差仪、透射电镜、扫描电镜、压痕仪、压汞仪、光学显微镜和超景深显微镜等设备分别在实验室和考古现场,系统研究了纳米氢氧化钙对郭杜万科大学城唐墓壁画残块和唐李道坚墓壁画残块的加固效果。结果显示,纳米氢氧化钙在壁画中具有良好的渗透性和加固效果,并且对壁画颜色影响极小。经纳米氢氧化钙加固后的壁画强度得到提高的同时内部结构没有明显变化。本工作成果对纳米氢氧化钙作为新型纳米材料运用到墓葬壁画加固中具有重要的指导意义。

This article presents the consolidation results of murals in a Tang tomb in Guodu Daxue District and Li Daojian tomb by applying calcium hydroxide nanoparticles.Colorimeter,TEM,SEM,indenter,mercury porosimeter,light microscope,and extended depth-of-field microscope were employed both on-site and inside the laboratory to systematically measure the results.Our study demonstrated that calcium hydroxide nanoparticles can have a good performance in terms of the penetration and consolidation for mural conservation,while the application of them only generate very limited impact on the color of murals.In addition,the microstructure of murals did not present significant changes after the consolidation of murals.This study holds significances for the application of calcium hydroxide nanoparticles in future conservation research.
