这里电解着色指交流电解着色法,也称二段电解着色法或浅田法。优点是着色古朴、典雅,并具良好的耐光、耐热,耐磨和耐蚀性。适用于铝建材、车辆、家具及五金零件等表面处理。而以在建材上着古铜及赤褐色应用最为广泛。着古铜色可使用镍盐、着赤褐色可使用铜盐电解液。这些电解液性能稳定,着色性能良好。但缺点是着深色时易发生氧化膜的剥落和击穿问题。 Electrolytic staining here refers to the AC electrolytic staining method, also known as two-stage electrolytic staining method or Asada law. The advantage is plain coloring, elegant, and with good light, heat, wear and corrosion resistance. For aluminum building materials, vehicles, furniture and hardware parts and other surface treatment. And in building materials on the use of bronze and auburn the most widely used. Bronze can use nickel salt, auburn can use copper salt electrolyte. These electrolytes are stable and have good coloring properties. But the disadvantage is that the dark oxide film prone to flaking and breakdown problems.
