摘要
改性纳米CaCO3稀悬浮液基本表现为牛顿流体行为,浓悬浮液表观粘度曲线存在低剪切速率剪切稀化幂律特征区和高剪切速率牛顿区两个区域,并具有明显触变性。改性CaCO3填充聚酯氨基清漆,在柔韧性、硬度、流平性及光泽等方面均优于未改性纳米CaCO3填充清漆。
Dilute CaCO 3 suspensions have newtonian behaviors. Concentrated CaCO 3 suspensions have shearing dilution phenomenon, accompanied with some degree of thixothopy characteristics. The coating filled with modified CaCO 3 has better properties in hardess, flexiblity and gloss than unmodified CaCO 3.\;
