摘要
Abstract
The halloysite from Xishuangbanna in Yunnan Province was studied in this paper.By measuring the slurry viscosity, the impact of stirring intens, solid content and pH value on the dispersion of halloysite in water without dispersant was determined.Moreover, the influences on the dispersion of halloysite in water with three various dispersants were discussed.The result showed that all of the three kinds of dispersants had good dispersing ability to halloysite.The capability of dispersants to the viscosity decreases successively: sodium polyacrylate, sodium hexametaphosphate, Sodium pyrophosphate.The appropriate pH value of sodium polyacrylate was greater than 7, sodium hexametaphosphate greater than 6.2, and Sodium pyrophosphate greater than 8.2.关键词
