摘要： The surface of a signal electrode is treated as substrate treatment. For example, an oxide film on the surface of the signal electrode is removed for roughing, and the roughened surface is used as a surface treated face. A coating of a fluororesin is provided on the surface treated face for lining or thermal welding to the lining material. A signal electrode is provided in the resin lining. Since the oxide film has been removed from the surface of the signal electrode for roughening, the adhesive force of the coating of the fluororesin is increased. The fluororesin coating and the resin lining melt each other, and, as a result, the fluororesin coating is strongly bonded to the resin lining, whereby the adhesion between the signal electrode and the resin lining can be increased without opening a hole in the signal electrode. A method may also be adopted in which a primer film is formed by substrate treatment on the surface of the signal electrode.
摘要翻译：将信号电极的表面作为衬底处理。例如，除去信号电极表面的氧化膜进行粗加工，将粗糙面用作表面处理面。在表面处理面上设置氟树脂的涂层，用于对衬里材料进行衬里或热焊接。信号电极设置在树脂衬里中。由于氧化膜已经从信号电极的表面去除以粗化，所以氟树脂的涂层的粘附力增加。氟树脂涂层和树脂衬里彼此熔融，结果，氟树脂涂层牢固地结合到树脂衬里，由此可以增加信号电极和树脂衬里之间的粘附，而不会在信号电极中打开孔。还可以采用在信号电极的表面上通过基板处理形成底漆膜的方法。
