| 摘 要： | 采用溶剂替换法制备了氟铃脲水悬浮剂，通过测定颗粒的平均粒径Dav和颗粒界面的Zeta电位，研究了分散剂种类、添加量以及有机相中乙醇的加入量对水悬浮剂分散稳定性的影响。 结果表明，在相同条件下，以苯乙烯丙烯酸共聚物(MOTAS)作为分散剂制备的水悬浮剂的分散效果较好；当MOTAS添加质量分数为1%时，Dav最小，Zeta电位绝对值最大，体系分散稳定性最好；在有机相中添加乙醇可以显著提高氟铃脲水悬浮剂的分散稳定性，当有机相中乙醇的加入质量分数增加至31.2%时分散稳定性达到最好。

| Abstract: | Effects of the dispersant,mass fraction of styrene-acrylic acid random copolymer(MOTAS),mass fraction of ethanol on the dispersion stability of hexaflumuron suspension produced by a solvent displacement technique were studied by means of measuring the average particle size and Zeta potential analysis.It has been found that the dispersive effect of MOTAS on the suspension was greater than others under the same condition.Under the condition of 1% mass fraction of MOTAS,Dav is the minimal,Zeta potential is the... |
