精炼镍阳极──通往工业最佳实践应用的途径

Refined nickel anodes——Pointers to industrial best practice

利用特地开发的测试方法在模拟电镀生产阳极溶解的条件下,研究了精炼原始金属镍阳极的功能特点,评价了阳极溶解效率、能耗、微观表面孔蚀、阳极装载密度和不溶残渣的积累。研究结果给钛篮用原始金属镍阳极类别的选择提供了指导,并能帮助终端电镀用户使用所推荐的最佳实践操作,通过控制镍库存、镍的工作投入、电能的消耗,以及最大限度地利用金属镍原料、劳动力和管理开支,以降低生产成本。减少因清洗而产生的金属镍、盐和电解液添加剂的浪费,也就减少了环境污染并有利于工人的职业健康和安全。本研究所报告的结果与6年来许多不同电镀厂和镀镍应用中观察到的情况一致。

Studies were conducted using test methods developed to determine performance characteristics of refined primary nickel under anodic dissolution in simulated production plant conditions. Efficiency of dissolution, power consumption, microsurface pitting, packing density, and accumulation of insoluble residues were evaluated. The results provide guidance on selection of primary Ni anode forms for use in titanium baskets enabling end users to adopt best practice for achieving cost savings in production by addressing the value of Ni inventory and application of working capital, consumption of electrical power and the optimum use of materials, labor and overheads. Reduction of waste in cleaning can save Ni metal, salts and electrolyte additives, and has consequent environment benefits and ameliorates worker occupational health and safety （OH＆S） risks. The results reported in those observed over 6 years plants and applications. this study are consistent with in many different Ni plating
