摘要
首先描述5种不同的硅藻页岩原矿和硅藻页岩粉体的外观和微观形貌,然后利用红外分析、X射线衍射分析、热失重分析等手段,分析硅藻页岩的化学成分、晶体形态和组成等。比较5种硅藻页岩的调湿性能,提出热失重分析方法也可以用于分辨和筛选高调湿性能的硅藻页岩。
Firstly,this article described the appearance and microscopic morphology of five different diatom shale ore and diatom shale powder,and analyzed chemical composition,crystal form and composition,etc.of diatom shale by means of infrared analysis,X-ray diffraction analysis,thermal gravity analysis.The humidity control performance of 5 kinds of diatom shale was compared,and the thermal gravity analysis method could also be used to distinguish and screen diatom shale with high humidity control performance.
