摘要

为了确认高温及γ辐照对改性钠基膨润土的影响。以内蒙古高庙子改性钠基膨润土为研究对象，利用X射线衍射仪和同步热分析仪分析了高温热老化、γ辐照老化和γ辐照-热程序老化作用对改性钠基膨润土性能和微观结构的影响。发现单纯热作用或单纯的辐照作用影响较小，而辐射–热程序老化作用会显著影响改性钠基膨润土的微观结构。经过1000 kGy–120℃–9000 h老化后，蒙脱石已完全转变为非膨胀性的伊利石，晶胞尺寸从老化前的15.8 nm 减小至约6.0 nm。所以应该考虑辐射–热效应对改性钠基膨润土的影响。

Abstract

Taking modified sodium bentonite, from Gaomiaozi, Inner Mongolia, as research object, the thermal aging, γ-rays irradiation aging, and radiation-thermal sequential aging were investigated by X-rays diffractometer and STA, separately. The corresponding effects on the property and microstructure of modified sodium bentonite demon-strate that the impact of either thermal aging or γ-rays irradiation aging is limited. However, the effect induced by ra-diation-thermal sequential aging is significant. After 1000 kGy γ-rays irradiation and thermal-aging for 9000 h at 120℃, montmorillonites have turned into illites; furthermore, crystal cells also have decreased from 15.8 nm to 6.0 nm or so in length. Therefore the thermal and γ-rays irradiation impacts should be considered in future research work.Cited
