研究明胶、硫脲、十二烷基磺酸钠、丙烯基硫脲及阿维同-A等作为添加剂 ,对阴极铜表面质量的影响。通过目测和金相显微观察对其影响效果进行了评价。结果表明 :十二烷基磺酸钠和阿维同-A的作用效果相似 ,丙烯基硫脲也能明显改善电铜表面质量 ,有望成为铜电解工艺中的添加剂。
The effects of gelatin, thiourea, sodium dodecyl sulfate, propenyl thiourea and avermectin-A on the surface quality of copper cathode were studied. The effect was evaluated by visual inspection and microscopic observation. The results showed that the effect of sodium dodecyl sulphate and ally-A were similar. Acrylthiourea could also improve the surface quality of copper electrowinning significantly and could become an additive in copper electrolysis process.
