在銅电解精炼过程中,采用硫脲和胶的混合添加剂能够大大提高电銅质量,降低直流电耗,提高劳动生产率和改善其他技术經济指标;但当用量和条件配合不当时,对阴极銅的外形质量会产生有害影响,甚至严重恶化。为了在生产中找出合理的添加剂用量与添加条件,我厂作了几种添加剂的极化效应試驗,經过一年多的生产实践已取得了一些經驗。
In the copper electrolytic refining process, the use of thiourea and plastic additives can greatly improve the quality of electro-copper, reduce DC power consumption, improve labor productivity and improve other technical and economic indicators; but when the amount and conditions with improper, the shape of the cathode copper Quality can have a detrimental effect, or even worse. In order to find a reasonable amount of additives in the production and the conditions for the addition, I plant made several additives polarization effect test, after more than a year of production practice has made some experience.
