摘要

本研究研究了一种新型的双面静电致动器（DSEA），该致动器由夹在铜网电极（上）和板电极（下）之间的介电层组成。DSEA是由一个多相方波电压通过高压放大器施加到每个电极驱动的。实验分析，利用铜和铝颗粒，并在DSEA上方使用一个吸气器，证明了电附着力作用于沉积在顶部表面的两种类型的颗粒。这一现象与颗粒质量的差异相结合，实现了铜和铝颗粒的高纯分离，回收率超过99%。

Experimental analysis of a new separation technique of aluminum/copper particles using a double-side electrostatic actuator

This study investigates a novel double-side electrostatic actuator (DSEA) comprising a dielectric layer sandwiched between a copper mesh electrode (top) and a plate electrode (bottom). The DSEA was driven by a polyphase square wave voltage applied to each electrode through high voltage amplifiers. Experimental analysis, utilizing copper and aluminum particles and employing an aspirator above the DSEA, demonstrated an electro-adhesion force acting on both types of particles deposited on the top surface. This phenomenon, combined with the difference in particle mass, enabled high-purity separation of copper and aluminum particles with recovery rates exceeding 99 %.
