Effect of Electrostatic Spraying Conditions on Droplet Deposition in Different Depth Areas on the Back of Target

Abstract

In order to explore the optimal spraying effect of different electrostatic spraying parameters on droplet deposition on the back of target, the application height, angle, charging voltage, and nozzle water pressure had been applied as spraying variables for the test designed to investigate on droplet density, deposition and coverage in different depth areas of the target. The results of the study showed that the height and angle of the spatial parameters of the application had a significant effect on the application effect. The droplet deposition effect decreased by 94.71%, 89.09% and 94.17% at different depths on the back of the target as the height increased from 20 to 50 cm. The deposition effects of droplets at different depths on the back of the target at 60° tilt angle are 5.91%, 9.81% and 51.97% of them at 0° tilt angle respectively. The results of orthogonal experiment showed that the optimal parameters of different depth areas on the back of different targets were inconsistent. The height and angle of application are the main influencing factors, when the target is warped up. The depth range of the target (5–7.5 cm) is greatly affected by the nozzle water pressure. In the actual spraying pesticides application, the appropriate operating parameters can be selected according to the size and attitude of the leaf surface to improve the spraying effect.
