【摘要】：随着我国水下考古事业的蓬勃发展,出水文物的科学保护已成为亟待解决的重要问题。表面各种附着物的清除是出水瓷器清洗的难点,现有的机械和化学清洗方法均存在着一定的局限性。在试清洗实验中,微纳米气泡展现了存在时间长、传质效率高、表面电荷形成的ζ电位高等不同于普通气泡的物理化学特性,对出水瓷器具有优越的清洗效果,因此有必要进一步对该清洗技术开展科学的安全性评价。选取打捞自"南海一号"的18件瓷片样品,进行了现状调查与病害检测,使用色差分析、光泽度分析、显微分析、显微测量等方法开展了安全性评价研究。实验结果表明,未发现微纳米气泡清洗技术会导致出水瓷器自身的颜色与光泽度产生明显变化,未发现其会导致瓷器釉面损伤,也未发现其会对瓷器已有裂缝产生影响。现有的评价结果表明,微纳米气泡清洗技术对于出水瓷器是基本安全的,为该技术在文物保护工作中的实际应用提供了重要依据。
[Abstract]:With the rapid development of underwater archaeology in China, the scientific protection of effluent cultural relics has become an important problem to be solved. The existing methods of mechanical and chemical cleaning have some limitations. In the experimental cleaning experiment, the microbubbles exhibit a long time and high mass transfer efficiency. The Zeta potential formed by surface charge is different from the physical and chemical characteristics of ordinary bubbles, and it has excellent cleaning effect on the porcelain out of water. Therefore, it is necessary to further carry out scientific safety evaluation of the cleaning technology. 18 samples of porcelain pieces salvaged from "Nanhai No. 1" are selected for current investigation and disease detection, color difference analysis, glossiness analysis and microscopic analysis. The safety evaluation was carried out by means of microscopic measurement and other methods. The results showed that the microbubble cleaning technology did not result in obvious changes in the color and gloss of the effluent porcelain itself, and it was not found that it would lead to the enamel damage of the porcelain. The existing evaluation results show that the micro-nano bubble cleaning technology is basically safe for the effluent porcelain, which provides an important basis for the practical application of the technology in the protection of cultural relics.
