武威磨咀子出土木器腐蚀病害与机理分析

武威磨咀子是甘肃古代糟朽木器的重要发现地之一,鉴于北方干燥地区出土的潮湿而糟朽(缺饱和水状态)漆木器与南方潮湿地区出土的浸饱水漆木器之间的差异,致使其保护材料与技术方法不同。本工作通过对武威磨咀子出土木器腐蚀病害与机理分析,着重从病害类型、影响藏品保存因素、材质物理化学组成、材质结构缺陷性及藏品的陈列和保存环境方面进行了全面、综合的科学分析。分析结果表明:武威磨咀子出土糟朽木器腐蚀病害发生是内外因素长期影响和作用的结果,得出保持保存环境的稳定性和控制木质材质中含水量是解决保护问题的关键,可为“十一五”期间甘肃馆藏木器文物实施全面保护修复提供详实的信息和技术支持。

The reasons for the corrosion of wooden relics excavated at Mozuizi, Wuwei

The Mozuizi of Wuwei is one of the most important archaeological sites of Gansu ancient wooden relics.Wooden relics excavated in the dry areas of Northern China in imperfectly saturated water state and those unearthed in the humid areas of Southern China in saturated water state,vary greatly in terms of the climatic conditions in which they were found.Thus,the protective materials and the techniques used to treat them are also different.This paper focuses on the wooden relics of Mozuizi,Wuwei and an overall scientific analysis of the corrosion,factors affecting preservation,chemical composition of the material,structural defects and the preservation climate.The result stated that the corrosion of the wooden relics is due to longterm influence and effect of internal and external factors.It also stated that maintaining a stable environment and controlling the moisture in the materials critical in solving the preservation problems.The analysis has provided dependable information and technical support for the overall preservation and restoration of these decaying wooden wares.
