摘要: 以水化膨胀能力最强的钠蒙脱石为研究对象,利用X′Pert Pro粉晶X射线衍射仪测试蒙脱石(001)晶面间距的原理,探索性地建立了使用X射线衍射仪直接、快速评价防膨剂防膨效果的方法和实验流程。系统总结了钠蒙脱石在去离子水、有机防膨剂、无机防膨剂中的(001)晶面间距变化情况。研究表明,蒙脱石(001)晶面间距的变化能够直观的反应防膨剂的防膨效果。并且采取了先抑后膨、先膨后抑的方法对防膨剂的稳定性、持续性进行了评价,拓宽了评价防膨剂的性能参数

Abstract: This paper establishes a direct,fast method and experiment process of evaluating the effect of the inhibitor for anti swelling by using X ray diffraction instrument — X ' Pert Pro,taking Na smectite for example which has the strongest swelling capacity,making use of the principle of testing the lattice spacing of smectite by X ray diffraction instrument.It systematically tests the changes of Na smectite treated by the distilled water,organic and inorganic inhibitors for anti swelling of clay,shown by the research,the changes of smectite's lattice spacing can directly reflect the effect of the inhibitor for antiswelling。And the author takes two different methods to evaluate the stability and durative of the inhibitor for anti swelling,increasing the performance parameter of evaluating the inhibitor for anti swelling.

Key words: smectite, attice spacing, clay mineral, expansion, Xray diffraction, inhibitor for anti swelling
