15491 分析了日本高性能低压腐蚀箔结构-性能特征,在此基础上讨论了腐蚀箔结构模型,并采用压汞仪测试和固态铝电解电容器性能测试进行模型验证。 The structure-property characteristics of high-performance low-voltage etched foils of lapan were analyzed and the structural model was discussed in detail. The mercury porosimeter measurements and electrical performance test or solidstate aluminum electrolytic capacitor were adopted to verify the model.
15492 结果表明,规格为U179H和LT23B腐蚀箔的性能差异主要是由于孔喉结构差异导致的。 The results show that the performance difference between U179H and LT23B etched foils is mainly due to their different pore-throat structures.
15493 为了维持电荷中性,Cl-离子倾向于聚集在蚀坑拐角处,促使拐角附近的薄弱点发生点蚀。而高浓度的Cl-离子利于与Al3+形成AlCl3盐膜,导致起蚀点附近的侧壁保持钝化状态,内部蚀坑呈现立方结构。 To maintain electrical neutrality, Cl- ions tend to accumulate at the corners of the pits, leading to pit initiation at weak points near the corners. Moreover,C1- ions with high concentration facilitate the formation of AlCl, salt film, which makes the sidewalls near the pitting point passivated and the internal pits structure kept the cubic structure.
15494 立方蚀坑连接口处形成一个窄小的通道,影响腐蚀箔比容和固态铝电解电容器引出率。 Consequently, a narrow channe is formed at the junction of the cubic etched cell, which affects the specific capacitance of the etched foil and the rate of capacitance withdrawing of the solid aluminum electrolytic capacitor.
