日本东京都立工业技术中心主任研究员三田郁夫、日本铝生产技术研究所所长山本崇等人针对建筑、光学仪器、铭牌、日用品等不同对象,介绍了目前在日本取得工业应用的铝阳极氧化自然发色、电解着色(二次交流电解,电流反向电解法)及染色等技术内容,现归纳整理如下(重点介绍反向电解法和有机染料着色). 一自然发色法阳极氧化自然发色有如下两种途径: (一) 用易发色的材料在特殊电解液中进行阳极氧化,此法所得膜层耐光性好,但电解液管理困难(与常用硫酸电解液相比),而且电解液成本高,氧化时需要高电压,高电流密度,色调种类也受到限制,为得到各种色调需配置各种专用电解槽.基于上述原 Japan Tokyo Metropolitan Industrial Technology Center researcher Yutaka Mitsuda, Japan Aluminum Production Technology Research Institute Yamamoto Chong and others for construction, optical instruments, nameplates, daily necessities and other different objects, introduced at present in Japan for industrial applications of aluminum anodized natural hair Color, electrolytic coloring (secondary AC electrolysis, current reverse electrolysis) and dyeing and other technical content are summarized as follows (focusing on reverse electrolysis and organic dye coloring.) A natural color anodizing natural hair color The following two ways: (A) with a chromogenic material in a special electrolyte for anodic oxidation, the light resistance of the resulting film is good, but the electrolyte management difficult (compared with the commonly used sulfuric acid electrolyte), and the electrolyte High cost, oxidation requires high voltage, high current density, color types are also limited, in order to get a variety of colors need to configure a variety of special electrolyzer.Based on the original
