摘　　要：将合成的树枝状聚合物作为分散剂加入到轻质碳酸钙中研磨,测定其润湿性、表观黏度和沉降高度,并进行扫描电镜分析,结果表明,加入1%该分散剂后,轻质碳酸钙聚集现象大大减弱,润湿性得到改善,沉降高度减少,悬浮液表观黏度下降50%以上,分散性明显改善。After adding 1% dendrimer as dispersant into the precipitated calcium carbonate, the wettability and dispersivity were improved obviously, the apparent viscosity of suspension dropped by more than 50%, SEM image showed that the aggregation phenomenon of the precipitated calcium carbonate was reduced.
