中高压铝电解电容器用电极箔的四级制造方法
摘要：
中高压铝电解电容器用电极箔的四级制造方法:将铝箔在95℃的水中浸10分钟,取出置于0.1－8%的柠檬酸和0.1－5%的柠檬酸盐的水溶液中,在70－95℃、20mA/(cm)2、150V的条件下,化成10分钟，取出水洗;置于0.1－5%的壬二酸和0.1－5%的壬二酸盐的水溶液中,在85℃、20mA/(cm)2、300V的条件下,化成10分钟，置于同于一级化成的水溶液中,在85℃、20mA/(cm)2、430V的条件下,化成10分钟，置于同于二级化成的水溶液中,在85℃、20mA/(cm)2、530V的条件下,化成10分钟，取出,在空气中滞留5分钟，置于同于二级化成的水溶液中,在85℃、20mA/(cm)2、530V的条件下,化成10分钟，取出,烘干。本发明优点:生产效率高,贮存性能好。
摘要（英）：

A four-stage process for preparing the electrode foil for medium-and high-voltage aluminium-electrolytic capacitor include such steps as immersing the aluminium foil in water at 95 deg.C for 10 min, taking out and placing in citric acid and the aqueous solution of citrate for formation under a certain condition for 10 min, taking out and washing in water; placing in azelaic acid and the aqueous solution of azelate for formation under a certain condition for 10 min, placing in the same condition as that for the first formation for 10 min, placing in the same condition as that for the second formation for 10 min, taking out and exposing in air for 5 min, placing in the same condition as that for the second formation for 10 min, and taking out and baking. Its advantages are high productivityand high storage performance.
