摘要
废印刷电路板上元器件的拆解技术是电路板资源化再利用的重要环节。通过研究甲基磺酸-双氧水体系下元器件的脱落率,得出优化的实验条件为:甲基磺酸浓度范围为3.0～3.5 mol/L,双氧水浓度范围为0.4～0.6 mol/L,反应时间45 min。在该实验条件下,实验样品中焊接元器件脱落率达到100%,实现了电路板基板与元器件的快速高效分离,为废旧电路板上元器件的拆解技术提供一定的技术支撑。
The dismantling technology of waste printed circuit board is an important part of the circuit board treatment. Through the study of removal rate of components under CH4 O3 S-H2 O2 system, the optimum experimental conditions were as follows： the concentration of methyl sulfonate was 3.0-3.5 mol/L, the concentration of hydrogen peroxide was 0.4-0.6 mol/L, and the reaction time was 45 min. Under the experimental conditions, the removal rate of components reached 100% and realized the rapid separation of the circuit board components, which provides technical support for the industrial disassembly of the waste printed circuit boards.
