摘要

开发了空气辅助静电喷涂装置和测量喷涂电流的装置。采用响应面方法对所开发的静电喷涂装置的性能进行了优化。电极直径、电极电压、电极位置和目标距离等最佳参数被确定为 30 毫米、2000 伏特、0 毫米和 400 毫米，以最大限度地提高电荷质量比（CMR）。此外，与不带电喷雾相比，带电喷雾的液滴沉积量增加了 1.5 至 4.6 倍，但均匀系数（2.13-2.14）和相对跨度系数（0.84-0.9）较低。

Performance optimization of an air-assisted electrostatic spraying unit using response surface methodology

An air-assisted electrostatic spraying unit along with a set-up to measure the spray current was developed. Response surface methodology was used to optimize the performance of the developed electrostatic spraying unit. The optimum parameters such as electrode diameter, electrode voltage, electrode position and target distance for maximizing charge-to-mass ratio (CMR) were determined to be 30 mm, 2000 V, 0 mm and 400 mm, respectively Predicted CMR under optimal conditions was experimentally validated. Furthermore, charged spray demonstrated 1.5 to 4.6 times higher droplet deposition with lower uniformity coefficient (2.13–2.14) and relative span factor (0.84–0.9) compared to uncharged spray.
