在銅、鉛电解精炼时所用电解槽,在目前国内国外一般以:木质內襯鉛、鋼筋水泥內襯鉛較多。近年来,由于塑料工業的發展,在国外已出现用塑料作为电解槽內襯的,在經济上和絕缘性能上,都比鉛襯电解槽优点多。但在我国目前情况下,由于沒有大量生产塑料,要用塑料来大量代替鉛皮是不够現实的。为了減少投資,改善电解槽絕緣性能,建議采用石油瀝青內襯电解槽,更能起到投資少收效大的作用。某厂电銅的电解槽設备,全为石油瀝青內襯,多年来使用結果証明,同样可以获得貿量优良的电解铜(99.97％Cu以上)及高的电流效率(97.5％以上)、高的銅回收率(99.85％以上)和低的硫酸消耗(6公斤/
In the copper, lead electrolysis used in electrolytic cells, at home and abroad in general at present: lined with wood, reinforced concrete lined with lead. In recent years, due to the development of the plastic industry, plastics have emerged as linings for electrolytic cells in foreign countries, which have more advantages in economy and insulation than lead-lined electrolyzers. However, in the current situation in our country, it is not realistic to use plastic instead of lead in large quantities because there is no mass production of plastic. In order to reduce investment and improve the insulation performance of the electrolyzer, it is recommended to use petroleum asphalt lined electrolyzer, which can play the role of less investment and less cost. Electrolytic cell equipment for a copper electrowinning plant is fully lined with petroleum bitumen and has been proven over many years to provide excellent electrolytic copper (above 99.97% Cu) and high current efficiency (over 97.5%) and high The copper recovery rate (99.85%) and low sulfuric acid consumption (6 kg /
