摘要
以高效氯氰菊酯为例,通过相图考察了非离子与阴离子表面活性剂及其不同复配比例对农药微乳剂相行为的影响。研究结果表明,同等使用剂量下,非离子与阴离子表面活性剂复配比单用非离子或阴离子表面活性剂得到更大的微乳区域,并且存在最佳复配比例。以此确定了非离子与阴离子表面活性剂最佳复配比例,对配方进行了优化。
The effects on the microemulsion phase behavior of nonionic and anionic surfactants along with different combinations of the two were determined using phase diagrams with beta-cypermethrin as the pesticide. Given equivalent use rates, combinations of anionic and nonionic surfactants produced larger phase diagram microemulsion regions than did anionic or nonionic surfactants used alone. An optimized surfactant mixture was identified for producing the beta-cypermethrin microemulsion.
