ABSTRACT

Archaeological wet wood undergoes acid degradation in an uncontrolled exhibition environment if the iron compounds are not completely removed prior to its preservation treatment with polyethylene glycol (PEG). However, completely removing such compounds that have deeply penetrated the wood tissue and fully control the exhibition environment are difficult. The Shinan shipwreck – on display at the Korean National Maritime Museum – is experiencing acid degradation, which in turn is affecting the surrounding air quality. This study investigated the effect of acid degradation on air quality of the exhibition gallery; the temperature, humidity, volatile organic compounds, aldehydes, nitrogen dioxide, and sulfur dioxide were monitored from April 2018 to March 2019. An analysis of the data revealed that the formaldehyde and sulfur dioxide concentrations in the exhibition hall were extremely high during the summer, which was largely attributed to the acid degradation of the shipwreck. Therefore, continuously operating a heating, ventilation, and air conditioning (HVAC) system and maintaining the temperature in the gallery below 24°C are required for safe conservation of the artefacts in the gallery.

韩国国家海事博物馆新南沉船酸降解对室内空气质量的影响

摘要

如果在用聚乙二醇 (PEG) 进行防腐处理之前没有完全去除铁化合物,考古湿木会在不受控制的展览环境中经历酸降解。然而,要彻底清除这些已经深入渗透木质组织并完全控制展览环境的化合物是很困难的。在韩国国家海事博物馆展出的 Shinan 沉船正在经历酸降解,这反过来又影响了周围的空气质量。本研究调查了酸降解对展厅空气质量的影响;2018年4月至2019年3月监测温度、湿度、挥发性有机物、醛类、二氧化氮、二氧化硫。数据分析显示,夏季展厅内的甲醛和二氧化硫浓度极高,这主要是由于沉船的酸降解造成的。因此,为了安全保护画廊中的文物,需要持续运行暖通空调 (HVAC) 系统并将画廊内的温度保持在 24°C 以下。
