故宫东华门内檐彩画多为清初彩画遗迹,它的保护修复建立在详细勘察内檐大木及天花彩画的保存现状及法式特征的基础上,采用了偏光显微镜、红外光谱等仪器,对彩画的颜料进行成分、工艺的科学分析,再根据分析结果筛选保护材料,针对病害情况特点及文物保护原则,尝试对不同病害采用不同的修复保护方法。在修复过程中尽量使用原材料和原工艺,确保真实性。除采用传统方法修复外,局部还采用经过试验且性能稳定的化学材料对彩画进行清洗和加固封护,现已取得良好的保护效果。
Most of the Donghuamen eaves of the Forbidden City were painted relics of the early Qing Dynasty. Based on the preservation status and the French characteristics of the eaves, large wood and ceiling paintings detailedly surveyed, the protection and restoration of the eaves were carried out with instruments such as polarized light microscope and infrared spectroscopy , The color of the paint pigment composition of science and technology analysis, and then screening based on the results of analysis of protective materials, according to the characteristics of disease and cultural relics protection principles, try different repair and protection methods for different diseases. In the repair process to make full use of raw materials and the original process to ensure authenticity. In addition to using traditional methods of repair, the local also tested and stable performance of the chemical materials on the painting cleaning and reinforcement of the seal has achieved good protection.
