摘要
表面坚硬附着物的清洗是出土瓷器保护的技术难点,现有的机械清洗、化学清洗、超声波清洗、蒸汽清洗等方法均存在技术局限性。对上海青龙镇遗址出土瓷片开展了微纳米气泡清洗研究,科学评价该技术的安全性能和清洗效果。使用色差分析、光泽度分析、釉面显微分析、裂缝显微测量等方法,对青龙镇出土瓷片及仿烧瓷片样品进行检测评估,验证了微纳米气泡清洗技术的安全性。开展微纳米气泡清洗、超声波清洗、蒸汽清洗3种物理方法的效果比对试验,综合评估其在清洗出土瓷片的表面附着物、缝隙污染物、断面污染物和金属侵蚀上的效果,验证了微纳米气泡清洗技术的有效性。
The cleaning of hard surface attachments,crevice contaminants and fracture contaminants is a technical difficulty for the conservation of unearthed porcelain.Current mechanical,chemical,ultrasonic and steam cleaning methods have their respective limitations.In this research,micro-nano bubble cleaning was applied to unearthed porcelain from Qinglong Town,and its safety performance and cleaning effectiveness were evaluated.Colorimetric,gloss and microscopic analysis of the glaze and microscopic measurement of crevices were used on the Qinglong Town samples and imitated porcelain samples,and showed that micro-nano bubble cleaning was a safe technique.Micro-nano bubble cleaning was compared with ultrasonic cleaning and steam cleaning so as to evaluate the effectiveness of cleaning of surface attachments,crevice contaminants,fracture contaminants and sites of metal erosion,and showed that micro-nano bubble cleaning was an effective method.
