Open publisher page 0 citations

Abstract

The bentonite from Jianping was used to purified and modified to prepare Na-bentonite.The influence of dosage conversion agent,the ore slurry concentration,conversion time,reaction temperature for expansion capacity of Na-bentonite were studied and the optimum 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 1.254 18 nm,the properties of Na-bentonite have been improved to be more widely applied in the papermaking field.
