河南博物院展室空调滤网吸附灰尘的分析

Chemical analysis of dust sampled from air-conditioner sieve of exhibition hall in Henan museum

博物馆环境中的粉尘对文物有不利的影响,需了解其成分和来源,为文物的保存环境的选择提供科学的数据。为此,采用红外光谱、X射线衍射、扫描电镜等手段对河南博物院空调滤网上的粉尘进行了成分分析和形貌分析。分析结果显示,粉尘包括无机的硅酸盐物质和各种纤维。分析结果说明,博物馆展室这样的人工环境中仍然含有对文物有危害的因素,而空调措施对去除粉尘具有一定的作用。

The suspended particles in the museun are hamLful to the cultural heritages. In this paper, dust sampled from the air - conditioner sieves were analyzed by FTIR, XRD and SEM. The results of the analysis showed that the component was silicates and organic fibers, which means that it contains hamLful materials in artificial environments. The air - conditioner is useful for removal of suspended particles in the airs.
