摘要
研究了中性油乳浊液同矿粒间的相互作用。从热力学角度讨论了油滴同矿粒作用的条件。通过对粒子间的范氏作用力、静电力和疏水作用力的定量计算和化学作用力的分析,解释了油滴同矿粒间作用的选择性。最后,在物理模型的基础上,说明了“空间效应”的产生。
The interactions between neutral oil droplets and mineral particles havebeen studied in this paper. In a view of thermodynamics. the conditionsrequired for interactions were discussed. The selectivities of interactions wereexplained by means of the quantitative calculation for Van der Waals force,coulombic force, hydrophobic forces and the expression of chemical forcebetween particles. And the 'steric effects' of interactions were disclosed basedon physical model of adsorption oil droplets on mineral surface.
