Recycling treatment of cable insulation resin generated from electric wires and cables was investigated. Conventional insulation PVC contains a lead component, tribase, as a thermal stabilizer and lead removal is necessary to recycle this PVC as insulation resin. This paper describes a solid surface adsorption method using ion exchange resin to remove the fine lead containing particles from PVC dissolved solution. Low lead concentration in the recovered PVC, complying with the requirements of RoHS, was achieved.
研究了电线电缆绝缘树脂的回收处理。传统的绝缘聚氯乙烯（PVC）含有三碱式硫酸铅作为热稳定剂，因此需要去除铅才能将这种 PVC 回收为绝缘树脂。本文介绍了一种使用离子交换树脂从溶解的 PVC 溶液中去除含细铅颗粒的固相亲和吸附方法。从回收的 PVC 中去除了符合 RoHS 要求的低浓度铅。
