摘要
以建平膨润土为原料,对其进行了提纯,并在提纯土的基础上对其进行钠化改型.探讨了钠化剂用量、矿浆浓度、搅拌时间、反应温度等对钠化膨润土膨胀容的影响,得到了最佳的钠化条件.同时,利用X射线衍射(XRD)对样品进行了简单的性能测试.结果表明,钠化改型后的膨润土d(001)=1.254 18nm,其性能有了较大提高,可以在造纸领域得到更加广泛地应用.
The bentonite from Jianping was used to purified and modified to prepare Na-ben- tonite. The influence of dosage conversion agent, the ore slurry concentration, conversion time, reaction temperature for expansion capacity of Na-bentonite were studied and the opti- mum conversion conditions were obtained in the experiment. The XRD was carried out to characterize the properties of samples. The results shows that d（001） is 1.9,54 18 nm, the properties of Na-bentonite have been improved to be more widely applied in the papermaking field.
