Abstract

The aim of the present paper is to study the feasibility of continuous dielectric barrier discharge (DBD) treatment of granular plastic materials in view of improving their triboelectric charging ability. The effects of the following DBD parameters were studied: the amplitude and the frequency of the applied high voltage, the thickness of the dielectric barrier, the distance between the electrodes of the reactor as well as the speed of the conveyor that was used for the transfer of the granular materials though the non-thermal plasma zone. The study was carried out on mm-size Polyethylene particles. It was found that the charge of DBD treated particles increases with the applied high voltage and decrease with the speed of the conveyor. Both the distance between the electrodes and the thickness of the dielectric barrier have a remarkable effect on the charge acquired after DBD treatment. Within the experimental domain of this study, the frequency of the high voltage does not significantly affect the efficiency of the tribocharging process.

介质阻挡放电暴露对颗粒塑料摩擦电荷的影响

本文的目的是研究连续介质阻挡放电(DBD)处理颗粒状塑料材料的可行性，以提高其摩擦充电能力。研究了以下DBD参数的影响:施加的高压的振幅和频率，介质阻挡层的厚度，反应器电极之间的距离以及用于通过非热等离子体区传递颗粒材料的输送机的速度。该研究是在毫米大小的聚乙烯颗粒上进行的。结果表明，DBD处理颗粒的电荷随施加的高压增大而增大，随输送速度的增大而减小。电极之间的距离和介质阻挡层的厚度对DBD处理后获得的电荷有显著的影响。在本研究的实验范围内，高电压的频率对摩擦充电过程的效率没有显著影响。
