摘要
利用残余质量浓度法、ζ电位测定和IR法研究了萘磺酸盐甲醛缩合物分散剂在灭幼脲颗粒界面的吸附量、吸附状态、ζ电位、吸附作用力等性能。分析认为,萘磺酸盐甲醛缩合物分散剂在灭幼脲颗粒界面吸附后具有静电排斥和空间位阻双重作用,这对维持灭幼脲水悬浮剂的分散稳定性具有重要意义。
The adsorption properties of naphthyl sulfonate formaldehyde condensation dispersant on the surface of chlorobenzuron,such as adsorbed amounts,adsorption state,ζ potential,adsorption force,were studied with remnants of concentration,ζ potential instrument and IR first in laboratory.Electrostatic exclusion and stereo-hindrance effect produced on the Interface of chlorobenzuron particles absorbing naphthyl sulfonate formaldehyde condensation dispersant are very important to maintain the stability of chlorobenzuron SC.
