气密展储空间内温湿度稳定性分析——以秦始皇帝陵博物院内气密展柜为例

Analysis of temperature and relative humidity stability in airtight spaces—a case study of an airtight showcase in Emperor Qinshihuang’s Mausoleum Site Museum

温湿度是影响文物保存的重要因素。为了研究气密展储空间内温湿度的变化情况,为文物的长期“稳定”展储奠定理论与实践基础,对秦始皇帝陵博物院内一台气密展柜7个月的温湿度检测数据进行分析。结果表明:展柜内温度随外界温度波动而波动,湿度稳定性取决于展柜气密性与展柜内外相对湿度差值,良好的气密性可以有效减缓外部环境湿度波动对展柜内湿度的干扰;气密空间内湿度短期内波动主要受环境温度影响。

Temperature and humidity are two of the most important factors that influence the preservation of cultural relics.It took seven months to get continuous test data from an airtight showcase in Emperor Qinshihuang’s Mausoleum Site Museum.The results show that the internal temperatures of the showcase fluctuated with the change of external temperatures and that the stability of humidity depends on the air airtightness and difference in relative humidity between inside and outside of the showcase.Good airtightness could effectively reduce interference of ambient humidity.A short-term fluctuation of internal relative humidity of an airtight space was mainly affected by environment temperatures,so good control of temperature could effectively reduce the fluctuation of relative humidity.
