通过静电方式分离聚氯乙烯（PVC）-金属粒状混合物的成分的效率取决于材料的水分含量。已进行实验室研究以确定待分离颗粒可接受的表面湿度。实验研究是在具有电晕静电场的卷式实验室分离器上进行的。十个 50% PVC 和 50% 铝或铜的样品，水分含量在 W=0-0.9% 范围内，经过相同的处理。几张图显示了湿度对颗粒混合物中 PVC 和金属回收率的影响。结果发现，当水分含量低于 0.3% 时，可以获得有效的 PVC-金属分离。根据PVC颗粒的电荷、放电过程的时间常数和电像力对实验结果进行定性讨论。>
The efficiency of separating by electrostatic means the constituents of a polyvinyl chloride (PVC)-metal granular mixture depends on the moisture content of the materials. Laboratory research has been carried out to determine the acceptable superficial humidity of the granules to be separated. The experimental study has been implemented on a roll-type laboratory separator with a corona electrostatic field. Ten samples of 50% PVC and 50% aluminum or copper, with a moisture content in the range W=0-0.9%, have been identically processed. Several diagrams show the influence of the humidity on PVC and metal recovery from the granular mixture. It is found that efficient PVC-metal separation can be obtained for a moisture content of less than 0.3%. Experimental results are qualitatively discussed on the basis of the electrical charge of the PVC grain, the time constant of the discharge process, and the electric image force.>
