摘要
轻质碳酸钙经改性后,具有了明显的抗水性,与水的接触角明显增大,增加了与有机相的相容性,吸油率下降近一半,同时SEM表明其聚集现象大大减弱。改性后的轻质碳酸钙在234.9℃以下是稳定的,且白度变化不大,完全可以满足加工生产的要求。
After modified by dendrimer, water-resistance and compatibility with organic phase of precipitated calci- um carbonate were improved, oil absorption was decreased about half and the aggregation phenomenon was reduced. The modified calcium carbonate kept its whiteness and stability under the temperature 234. 9℃.
