【摘要】：世界文化遗产云冈石窟在长期的保存过程中,因自然因素和人为作用,石窟石雕表面产生了严重的黑垢病害,不仅影响到文物的艺术价值,也是一个潜在的文物安全隐患。本课题针对石质文物表面的黑垢病害现象,首先回顾了近年来国内外相关的研究情况,全面了解了石质文物表面黑垢病害的生成机理、研究方法和进行黑垢病害处理的质文物清洗技术。在此理论前沿基础上,初步调查了云冈石窟石雕表面主要污染物类型,对其中黑垢病害的分布、组成和来源进行了探讨。之后,通过干湿循环作用、so2腐蚀循环作用和干湿与so2共同腐蚀循环作用,研究了在不同的影响条件下,黑垢病害对云冈砂岩的作用效果。结果显示,粉尘黑垢在一定程度上促进了云冈砂岩的破坏,而烟熏黑垢,则在一定程度上减缓了云冈砂岩的破坏。因此,认为在实施云冈石窟石雕表面黑垢的清洗实践中,在不考虑艺术价值影响的前提下,烟熏黑垢可暂时保留,而粉尘黑垢却必须进行清洗。最后,通过实验室的初步研究,基本筛选出了具有一定清洗效果的黑垢清洗剂。
[Abstract]:During the long-term preservation of the Yungang Grottoes, the world cultural heritage, due to natural factors and human actions, the surface of the grottoes has a serious black scale disease, which not only affects the artistic value of the cultural relics, but also is a potential hidden danger to the safety of cultural relics.This topic aims at the phenomenon of black scale disease on the surface of stone cultural relic. Firstly, it reviews the related research situation at home and abroad in recent years, and fully understands the formation mechanism of black scale disease on the surface of stone cultural relic.Research methods and cleaning technology of quality cultural relics for black scale disease treatment.On the basis of this theoretical frontier, the main pollutant types on the surface of Yungang Grottoes are investigated, and the distribution, composition and source of the black scale disease are discussed.After that, the effect of black scale disease on Yungang sandstone under different influence conditions was studied by the effect of dry and wet cycle and so _ 2 corrosion cycle together with so2.The results show that dust black scale promotes the destruction of Yungang sandstone to some extent, while smoke black scale slows down the destruction of Yungang sandstone to some extent.Therefore, it is considered that in the practice of cleaning black dirt on the surface of Yungang Grottoes, the smoke black dirt can be kept temporarily, but the dust black dirt must be cleaned without considering the influence of artistic value.Finally, through the preliminary research in the laboratory, the black scale cleaning agent with certain cleaning effect was basically screened out.
