助剂S240对水分散性粒剂及乳油药液雾化的影响

为探究药液性质对喷头雾化的影响,该文应用粒子图像分析系统、高速摄影仪及粒径分析仪对ST110-03喷头与IDK120-03喷头进行试验研究,分析了水分散性粒剂Don-q、乳油Score及2种药剂条件下助剂Breakthru S240浓度对雾化区及雾滴谱的影响。未添加助剂时,农药剂型不同,2类喷头的雾化区及雾滴体积中径（volume medium diameter,VMD）均发生显著变化,水分散性粒剂溶液与自来水的雾化区结构、液膜长度和VMD相差不大;乳油溶液可以使2类喷头的雾化区结构发生显著变化,液膜长度分别减小35.2%和40.5%,VMD分别增大13.5%和28.9%;不同剂型农药条件下,...

Summary:为探究药液性质对喷头雾化的影响,该文应用粒子图像分析系统、高速摄影仪及粒径分析仪对ST110-03喷头与IDK120-03喷头进行试验研究,分析了水分散性粒剂Don-q、乳油Score及2种药剂条件下助剂Breakthru S240浓度对雾化区及雾滴谱的影响。未添加助剂时,农药剂型不同,2类喷头的雾化区及雾滴体积中径（volume medium diameter,VMD）均发生显著变化,水分散性粒剂溶液与自来水的雾化区结构、液膜长度和VMD相差不大;乳油溶液可以使2类喷头的雾化区结构发生显著变化,液膜长度分别减小35.2%和40.5%,VMD分别增大13.5%和28.9%;不同剂型农药条件下,随助剂浓度增大,2类喷头液膜区及破碎区结构均发生不同程度的变化,液膜长度均先减小后增大,VMD先增加后减小,即液膜长度变化与VMD变化呈现负相关性。结合药液理化性质研究发现表面张力是影响雾化的重要因素之一。该研究可为田间助剂浓度的添加范围及喷头雾化特性的模拟与模型建立提供参考。

In order to study effect liquid characteristic on nozzle atomization process, this article applied Particle Droplets Image Analysis, high speed camera, and Malvern particle sizer to carry out experiment which focused on how Don-q, Score and the concentration of Breakthru S240 affected spraying sheet and droplet spectrum with conventional fan nozzle ST110-03 and anti-drift nozzle IDK120-03. The concentration of Don-q, Score solution was 0.275 % and 0.1 % respectively and the concentration of Breakthru S240 added into Don-q and Score was 0, 0.01%, 0.03%, 0.05%, 0.07%, 0.1%.
