摘要
长粒子的电铜加工性能差 ,严重影响电铜质量。本文结合生产实践 ,阐述了电铜长粒子是由电解电流密度不均、添加剂量不当和悬浮物超标等原因所致。可根据电铜粒子的不同特征来分析形成粒子的具体原因 ,并采取相应的措施来预防和消除电铜粒子 ,提高电铜质量。
The cathode copper with nodules is poor in processing performance.Such nodules cause serious influence on quality of cathode copper.This paper,combined with production practice,describes the formation of nodules on cathode copper and removal methods.Nodules on cathode copper are basically caused by uneven distribution of current density,improper amount of additives to electrolyte,overmuch suspended material in electrolyte,etc.In the light of nodule characteristics,specific reasons for the nodule formation can be analyzed and appropriate measures can be taken to prevent or eliminate nodules.
