Abstract:

The unearthed relics suffer deterioration in some archeology museums of China because of improper preservation environment. To acquire appropriate environmental factors for the conservation of the historical relics, this paper designs the multi-field coupling test chamber orientated to research the quantitative relationship between deterioration and environmental factors(including air temperature and humidity, light, gaseous pollutants, soil moisture and soluble salt).The test chamber is made up of test chamber body, air curtain and air-conditioning system, gaseous pollutants control system, solar radiation simulation system and soil regulation system, which can realize the complex environment of air-relic-soil. This paper focuses on clarifies the test chamber's design index, system composition, as well as implementation and function of each subsystem, and makes performance testing of air temperature and humidity. The experimental result shows that air temperature and humidity is 10-35℃ and 30%-95%, and the accuracy of temperature and relative humidity is ≤1℃ and ≤3%,respectively, which can meet air temperature and relative humidity testing requirements.

Key words: relics preservation, multi-field coupling test chamber, relics deterioration, environmental factors

摘要：

为研究遗址博物馆中文物病害(干裂、返碱等)与环境参数(空气温湿度、光照、污染物浓度、土壤含水量、可溶盐含量等)的定性、定量关系,确定遗址文物保存适宜的环境参数,设计研制了适宜遗址文物保存环境研究的多场耦合实验舱。实验舱主要包括本体、空气净化和气幕隔离调控系统、污染气体控制系统、太阳辐射模拟系统及土环境调控系统5个子系统,可实现"土壤-文物-大气"多场耦合的复杂环境模拟。本文主要介绍实验舱设计指标、系统组成以及各子系统的实现方式和功能,并选取9组具有代表性的温湿度值作为测试对象研究实验舱中空气温湿度的均匀性和稳定性。结果表明,在多种工况下,多场耦合实验舱中空气温湿度的均匀性、稳定性均分别为≤1℃和≤3%,满足实验舱中空气温湿度的设计要求。
