目前，工业上通常采用的济南铝板http://www.jngdly.com/着色法有自然着色法、电解着色法和化学着色法以及树脂粉末静电喷涂法。
Currently, the industry commonly used aluminum coloring Jinan natural coloring, electrolytic and chemical coloring coloring and resin powder coating method.
   
济南铝板化学着色法也就是所谓的浸渍着色法，这是早期用于铝阳极氧化膜着色方法。化学机理是基于多孔膜层有如纺织纤维一样吸附染料的能力，染料在水中分离成单分子，着色时，染料被吸附在孔隙表面并向孔内扩散、堆积，且和氧化铝进行化学或物理作用而使膜层着色，经封孔处理，染料被固定在孔隙内。
Jinan aluminum chemical coloring is called dipping coloring, which is early for anodized aluminum coloring methods. Chemical mechanism is based on a porous film like woven fabric as dye adsorption capacity, the dye in the water into a

single molecule separated, coloring, the dye is adsorbed to the surface of pores in the pore diffusion, accumulation, and alumina and a chemical or physical action leaving the colored film, by sealing treatment, the dye is fixed within the pores.

济南铝板http://www.jngdly.com/化学着色法具有工艺简单、效率高、成本低、设备投资少、着色域宽、色泽鲜艳等优点。但是大面积的制品容易出现颜色不均，着色后清洗、封孔不当或受到机械损伤时，容易褪色，着色膜的耐光性能差，因此一般作为室内装饰、日常用小型铝制品的着色处理。
Jinan aluminum chemical coloring process is simple, high efficiency, low cost, less investment in equipment, coloring domain wide, bright color, and so on. However, a large area of products prone to uneven color, coloring after cleaning, improper sealing or mechanical damage, it is easy to fade, poor light fastness of the colored film, it is generally used as interior decoration, with a small aluminum products daily coloring treatment.
