溶剂替换法制备氟铃脲水悬浮剂及其分散稳定性
Preparation of Hexaflumuron Suspension by Solvent Displacement Technique and Its Dispersion Stability
摘要
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 maximal and the dispersion stability is the best. The dispersion stability of the hexaflumuron suspension can be greatly enhanced when the ethanol was added. The dispersion stability attained best in solution containing about 31. 2% mass fraction of ethanol.关键词
