作者测定了乳状液中的油珠及矿粒的动电位以及油酸钠(NaOl)的吸附量,并按疏水作用理论计算了油珠与疏水矿粒间的作用势能。结果表明,当考虑疏水作用势能时,疏水矿粒与油珠在相距约60～80nm时,两者之间开始出现强烈的吸引力,并最终发生粘附现象。这是非极性油对疏水作用起强化作用的前提条件。 The authors measured the kinetic potentials of oil droplets and mineral particles in emulsion and the adsorption capacity of sodium oleate (NaOl), and calculated the potential energy of interaction between oil droplets and hydrophobic minerals according to the theory of hydrophobic interaction. The results show that when hydrophobic potential energy is considered, hydrophobic minerals and oil beads begin to show strong attraction between the two when the distance between them is about 60 ~ 80nm, and the adhesion finally occurs. This is a non-polar oil on the role of the role of strengthening the role of hydrophobic preconditions.
