废旧印刷电路板资源化研究综述

The Methods for Recycling of Waste Printed Circuit Boards

在大力倡导建设资源节约型和环境友好型社会的今天,加大对废旧印刷电路板的资源化研究有着特别重大的意义。首先介绍了废旧PCB的组成,并对废旧PCB中金属的含量做了分析,指出废旧PCB具有很大的可再生利用价值。着重综述了废旧PCB资源化的常规用法,主要包括热处理法、化学处理法、和物理机械处理法,并对这些方法做了的分析归纳。通过对各种方法的综述可以看出采用物理机械方法回收废旧电路板应该是今后的发展方向。

Today, we strongly advocated the building of a resource-saving and environment-friendly society. Increasing the study for the recovery of the waste PCB has a special significance. Firstly, it describes the composition of PCB waste and analysis the metal contents in the waste PCB and also points out PCB waste has a great value for the recovery. It reviews the conventional methods of recycling waste PCB which mainly include that heat treatment method, chemical treatment method, physical and mechanical treatment method and made a brief analysis and induction for these methods.It also points out that the physical and mechanical methods for the recovery of waste PCB should be the trend in the future.
