以典型废印制电路板湿法剥离得到的元器件为研究对象,通过筛分和磁选相结合的物理方法,分离其中的电容器。研究发现,筛分后电容器分布在9.5-19 mm和4.0-9.5 mm范围内,并且50%以上的元器件与电容器得到分离。9.5-19 mm范围内的元器件经过磁选,可以将强磁性的铜线绕阻类元器件分离出来,剩余元器件采用8 mm宽的条形筛进行筛分,筛上物主要为电容器,筛下物主要为芯片和引脚;4.0-9.5 mm范围内的元器件经过磁选,可以将92.93%的电容器分离出来。

Through physical methods combined by screening and magnetic separation, the capacitors were separated from waste printed circuit board components. It was found that after screening more than 50% of components were separated form capacitors which were located in a range of 9.5-19 mm and 4.0-9.5 ram. Components with strong magnetic force in 9.5-19 mm range, like copper winding, could be isolated by magnetic separation, and the others were screened by an 8ram wide strip sieve. Then the capacitors were gained above the sieve, and the chips and pins were left. For 4.0N9.5 mm range, 92.93% capacitors can be isolated by magnetic separation.
