文物保存微环境用调湿材料调湿性能研究

Research on the performance of some humidity-controlling materials used in museum micro-environments

文物在贮存、展示过程中面临着环境温度、湿度、污染物对它的影响。其中,湿度是关键的一种因素。采用调湿材料控制文物保存微环境的湿度是最经济实用的方法。为了科学选用调湿材料,本工作选择了Art-Sorb^(?)调湿产品与纤维调湿板,通过试验,评价了它们的湿容量、吸放湿性能、响应速度、调控时效等调湿性能。检测结果显示,Art-Sorb^(?)调湿产品与纤维调湿板均有较好的调湿功能,但两者比较,纤维调湿板具有湿容量大、用量少的优点;而对Art-Sorb^(?)产品,则其平衡湿度受外界环境温度的变化较小。

Cultural relics are affected by temperature,humidity and pollutants during storage and exhibition.Humidity is one of the key environmental factors.The use of humidity - controlling materials to adjust humidity in museum micro—environments is the most economical and practical method to protect objects.In order to obtain a scientific understanding of these materials,Art - Sorb^(?) humidity controlling products and fiber humidity controlling board were selected for performance tests.This paper describes tests,to evaluate these materials with regard to humidity - control performance such as moisture capacity,moisture adsorption and desorption performance,response speed and time required to achieve regulation.These studies show that these materials have good humidity control performance.However,the fiber humidity controlling board has a larger moisture capacity and therefore less materials is required,while Art - Sorb^(?) depends less on environment temperature.
