电解电容器的特性与经腐蚀和制型后的铝箔的性质有很大关系,尤其是铝箔的组织和织构会影响其比容C=(ε/4πδ)(S/S’)的大小(式中ε-制型时形成的氧化膜之介电系数;δ-电介质厚度,S-氧化层的表面积,S’-受试试样的名义表面积).铝箔的组织和织构决定着受腐蚀表面的凸凹状况, Electrolytic capacitor characteristics and corrosion and shape of the foil has a lot of the nature of the foil, especially the organization and texture of aluminum foil will affect its specific volume C = (ε / 4πδ) (S / S ’) size Dielectric coefficient of oxide film formed during ε-formation; δ-Dielectric thickness, S-oxide surface area, S’-Nominal surface area of ​​test specimen.) The texture and texture of the aluminum foil determine the corrosion resistance of the surface to be etched The convex and concave conditions,
