Study of Droplet Characteristics of Electrospray Coating Method as a Function of Ring Electrode Parameters; 링 전극 변수에 따른 정전 분무 코팅법의 액적 특성연구

초록

Among chemical coating methods, deposition using electrostatic spraying is commonly employed in coating processes to control the deposition rate, thickness, and properties of the formed materials. In this study, we considered the following variables: ring electrode, ring diameter (RD), ring voltage (RV), and nozzle-ring distance (NTR). Through experiments, we determined the atomization mode applied voltage, Sauter mean diameter (SMD), and SMD standard deviation of the nozzle. Additionally, we derived the voltage intensity and electric field along the axial direction using ANSYS maxwell to identify the optimal ring electrode atomization conditions. © © The Korean Society for Precision Engineering.
