Abstract

Electric charge accumulation on fibrous dielectric media during manufacturing processes can easily attain high levels of electrostatic hazard. In a previous paper, the authors addressed the problem of the accelerated discharge of such materials using a commercial ion generator. The aim of the present work is to evaluate the various factors that influence the efficiency of charge neutralization performed using a wire-type corona electrode energized from either a sinusoidal or a triangular AC high-voltage supply. The experiments were performed on 400 µm-thick non-weaved sheets of polypropylene and polyester, in ambient air. The samples were charged for 10 seconds using a triode - type corona electrode system of negative polarity. The surface potential on the charged media, which was in contact with the grounded electrode, was then measured with an electrostatic voltmeter. After 10 minutes, the media was moved beneath a neutralizing electrode, connected to a high-voltage amplifier. The efficiency of the neutralization was quantified by the ratio between the surface potential after and prior the charged sample exposure to AC corona discharge. The experimental design methodology was employed for evaluating the effects of two factors: amplitude (range: 16 to 24 kV) and frequency (range: 20 to 400 Hz) of the neutralizing voltage. The potential at the surface of the non-woven fabrics after neutralization was found to vary insignificantly with thermal conditioning and signal waveform, but was significantly lower for higher frequencies and amplitudes.
用于无纺布纤维电介质加速放电的正弦和三角形高压中和器
在制造过程中,纤维介电质上的电荷积累很容易造成严重的静电危害。在之前的一篇论文中,作者使用商用离子发生器解决了此类材料的加速放电问题。本研究旨在评估影响使用正弦或三角交流高压电源供电的线型电晕电极进行电荷中和效率的各种因素。实验在环境空气中对 400 微米厚的聚丙烯和聚酯无编织片材进行。样品使用负极性三极管式电晕电极系统充电 10 秒钟。然后用静电电压表测量与接地电极接触的带电介质的表面电位。10 分钟后,将介质移至中和电极下方,中和电极与高压放大器相连。中和效率通过带电样品接触交流电晕放电后与接触交流电晕放电前的表面电位之比来量化。实验设计方法用于评估两个因素的影响:中和电压的幅度(范围:16 至 24 kV)和频率(范围:20 至 400 Hz)。结果发现,中和后无纺布表面的电位随热调节和信号波形的变化不大,但频率和振幅越高,电位越低。
