1、铝和铝合金表面处理的过程首先对铝和铝合金进行电解抛光和化学抛光,然后在碱和碱土金属中的氢氧化物中,或者在金属盐和易形成阻挡膜的有机酸中,或者在无机酸的水溶液中进行交流电解。在交流电解时,由于铝表面产生气泡的作用,形成了具有条纹的膜。其后,把膜放入含有金属盐的溶液中进行交流电解处理和在染料、颜料中浸渍着色; 1, aluminum and aluminum alloy surface treatment process First of aluminum and aluminum alloy electrolytic polishing and chemical polishing, and then alkali and alkaline earth metal hydroxide, or in the metal salt and easy to form a barrier film of organic acids, Or in an aqueous solution of an inorganic acid for AC electrolysis. During AC electrolysis, a striped film was formed due to the effect of air bubbles on the aluminum surface. Thereafter, the film is placed in a solution containing a metal salt for AC electrolytic treatment and dyed in a dye or a pigment;
