Dynamic Surface Tension of Selected Nonionic Agricultural Surfactants at Surface Ages Relevant to Component Processes in Spray Application

摘要

Dynamic surface tension data for selected nonionic surfactants, pesticides and other miscellaneous liquids are presented. Surface tension was measured using the oscillating jet technique at surface ages ranging from 0.5 to 7 ms. These early measurements are particularly important since new surfaces are being rapidly created, and they represent the time frame of spray droplet formation and impaction processes.
