摘要
以高庙子天然钙基膨润土和其改性钠基膨润土为研究对象,利用X-射线衍射对电子辐照-热顺序老化作用和γ-射线辐照-热顺序作用前后的样品进行了吸水膨胀能力大小测试,结果表明,在本试验条件下,两种不同类型的辐照-热顺序老化作用对高庙子膨润土膨胀能力的影响微弱,老化后的样品基本保持了原始样品的吸水膨胀能力。
The natural bentonite and modified sodium bentonite of Gaomiaozi （GMZ） were investigated, and the swelling capacity of samples after electron irradiation-thermal sequential aging and y-ray irradiation-thermal sequential aging were analyzed by XRD. The results show that the influences of two different irradiation-heat aging modes on swelling capacity of GMZ bentonite are weak. The bentonite can maintain its original swelling capacity after the aging process.
