摘要: 利用马尔文激光粒度仪对不同条件下制备的水包油型乳状液粒径分布进行了研究。结果表明,水包油型乳状液粒度随活性剂的质量分数增加而减小,当活性剂的质量分数达到0.5%时,乳状液体系很稳定,粒度随静置时间变化较小;聚合物的加入使水包油型乳状液粒度先增大后减小再增大;在一定剪切速率范围内,水包油型乳状液粒度随剪切速率的增加而减小,当剪切速率超过6 000 r/min时,粒度几乎不随剪切速率发生变化;剪切达到一定时间后,乳状液粒径随剪切时间变化很小;在低剪切速率下,剪切时间较短时形成的乳状液体系不稳定。

Abstract: The particle size distribution of oil⁃in⁃water emulsion prepared under different conditions was studied by Malvin laser particle size analyzer. The results showed that the particle size of the oil⁃in⁃water emulsion decreased with the increase of the concentration of the active agent. When the concentration of the active agent reached 0.5%, the emulsion system was stable and the particle size changed little with the time of standing. With the addition of polymer, the particle size of oil⁃in⁃water emulsion increased first, then decreased and then increases. Within a certain shear rate range, the particle size of oil⁃in⁃water emulsion decreased with the increase of shear rate. When the shear rate exceeded 6 000 r/min, the particle size hardly changed with the shear rate. After shearing for a certain time, the change of emulsion particle size with shearing time was very small. At low shear rate, the emulsion system formed with short shear time was unstable.
