一、前言铝合金阳极氧化膜的着色处理有自然发色、电解着色和化学染色法三种工艺。化学染色法是将经阳极氧化处理的铝件浸入含有染料(有机或无机)的溶液中,染料渗入多孔膜,发生物理和化学吸附而获得染色效果。虽化学染色的日晒牢度、磨耗性和耐蚀性相应较差,然而由于具有色调广泛、色泽鲜艳、工艺简单、成本低廉等特点,因此不失为铝制日用品及室内装饰用品的主要着色手段。国内现用的有机染料除瑞士产的Sandoz染料外,也用国产酸性毛元黑ATT。前者价格昂贵,后者性能往往不能满足要求。本工 First, the foreword Aluminum alloy anodizing film coloring natural hair color, electrolytic coloring and chemical dyeing three kinds of processes. Chemical staining is the anodized aluminum immersed in a solution containing dye (organic or inorganic), the dye into the porous membrane, the physical and chemical adsorption to obtain the dyeing effect. Although the chemical staining of the sun fastness, wear resistance and corrosion resistance of the corresponding poor, but with a wide range of colors, bright color, simple process, low cost and so on, it is the main coloring aluminum daily necessities and interior decoration means. Domestic organic dyes in addition to the Swiss-made Sandoz dye, but also with the domestic acid hair yuan black ATT. The former is expensive, the latter often can not meet the performance requirements. This work
