It is shown that conventional emulsion polymerization process leads to high gloss film and soap-free or micro-soap processes will lead to good water resistance and lower foaming.
研究表明采用常规乳液聚合涂膜的光泽较高，而采用无皂和微皂乳液聚合涂膜的耐水性较好，涂料的起泡性较低。
PH lower will reduce the stability of the emulsion system, emulsion, eventually forming cannot even oil-in-water.
PH低会降低乳化体系的稳定性，甚至无法乳化，最终形成水包油。
The simulation results show that local voidage calculated by bubble and emulsion model is observably lower in the bubble nose region, compared with that calculated by area weighted averaging.
模拟结果表明：气泡乳相模型在气泡鼻区域计算的局部空隙率显著低于面积加权平均法的计算结果，因而在该区域能较大幅度地修正曳力。
