化学固沙剂固沙作用机理研究

A Study of Sand-fixation Mechanism of Chemical Sand-fixation Agent

随着沙漠化治理的需要,化学治沙技术将会有广阔的发展前途,进一步开展化学治沙作用机理的研究是十分重要和必要的。化学固沙作用机理既包含简单的物理、化学过程,也包含许多物质结构、胶体化学等方面的问题,是一个比较复杂的过程。通过红外光谱法对7种化学固沙剂进行固沙作用的研究,了解了不同化学固沙剂与沙粒的固化、固沙过程作用机理,了解不同化学固沙剂的性能,为优良化学固沙剂筛选应用起到一定的技术参考作用。

It is both important and necessary to conduct further research on chemical sand-fixation mechanism as chemical anti-desertification technology will have positive development prospects in desertification control. Chemical sand-fixation mechanism includes simple physical and chemical processes as well as complex processes such as material structure and colloid chemistry. A research on seven chemical sand-fixation agents by infrared spectroscopy were carried out to study the chemical sand-fixation mechanism of the agents, hoping to provide reference for sand fixing agent selection and application.
