酸性蚀刻液无氯气电解设备与蚀刻机循环并同步工作,对比传统隔膜电解工艺,具有设备投资小、使用场地小、运营成本低、电解过程中不产生有毒气体氯气等优点.但工艺条件控制复杂,限制了其大规模的应用.在实际生产中,不同厂家蚀刻产线的工作情况各不相同,因此电解设备的工艺条件也需要进行相应调整.再生液氧化还原电位(ORP)值、电解设备和蚀刻机的循环流量以及电解设备的电流,是影响工艺稳定性及电解效率的3个关键因素.结合实验数据及提铜车间电解设备的调试结果,对这3个工艺参数的作用及内在逻辑关系进行阐述.
The acidic etching liquid chlorine-free electrolysis equipment and etching machine cycle and work synchronously.Compared with traditional diaphragm electrolysis process,it has advantages such as small equipment investment,small working space,low operating cost,and no toxic gas chlorine generated during the electrolysis process.However,due to the complex process conditions,the large-scale application of this process is limited.In actual production,the working conditions of etching production lines vary among different manufacturers,so the process conditions of electrolysis equipment cannot be fixed but need to be adjusted accordingly.The oxidation reduction potential(ORP)value of the regeneration solution,the circulating flow rate of the electrolysis equipment and etching machine,and the current of the electrolysis equipment are three key factors that affect process stability and electrolysis efficiency.This article will elaborate on the role and internal logical relationship of these three process parameters based on experimental data and the debugging results of the electrolysis equipment in the copper extraction workshop.
