摘要
建立回收工艺模型,利用中心复和设计方法对FR-4型废旧线路板的超临界CO2流体回收工艺进行实验研究。分析温度和处理时间对线路板的分层率、玻璃纤维布的纬向抗拉强度及二者综合效应的影响;建立回收工艺输出工艺参数的多元二次模型方程,由此得到超临界CO2回收FR-4型线路板的最佳温度和处理时间,并通过实验验证最佳温度和处理时间的准确性。
To create a model for recycling technology, process employing supercritical fluid CO2 （SCF-CO2 a waste FR-4 printed circuit board （PCB） recycling ） is studied using central composite design. The influence of temperature and treatment time on the PCB delamination ratio, latitudinal tensile s glass fiber sheets, and their synthesized effect are analyzed. The optimal temperature and treat for FR-4 PCB recycling with SCF-CO2 are found by building a quadratic polynomial equation output parameters in recycling technology. The accuracy of the derived optimal temperature and time is validated by a series of experiments.
