氧化铝板具有丰富的色彩和现代金属外观，因此越来越多的产品金属外壳采用氧化工艺来达到美观实用的效果。氧化铝板广泛应用于标志、移动电子设备、家电、建筑、装饰等行业。氧化铝板的颜色也很丰富。有自然色、黑色、玫瑰金、雾白色、不锈钢、金色等多种颜色可供选择。不同行业可选择不同外观的氧化产品。在标志行业，可根据产品的特点和需求选择不同的颜色。在标志的应用中，通常选用自然色、不锈钢色、金色等基本颜色，使标志看起来简洁大方，突出标志本身的特点。

阳极氧化铝板是将铝板置于相应的电解液（如硫酸、铬酸、草酸等）中作为阳极，在特定条件和外加电流的作用下进行电解。
1.阳极氧化铝板氧化膜形成的一般原理：
以铝板为阳极，将其置于电解液中，利用电解效应使其表面形成氧化铝膜的过程称为铝板阳极氧化。设备中的阴极是电解溶液中化学稳定性高的数据，如铅、不锈钢、铝等。铝阳极氧化的原理实质上是水电解的原理。当电流通过阴极时，氢被释放；在阳极上，分离出的氧不仅是分子氧，还有原子氧（o）和离子氧，在反应中通常用分子氧表示。铝作为阳极被从中分离出来的氧气氧化，形成无水氧化铝膜。生成的氧气与铝并不完全相同，部分氧气以气态方式分离。
2.阳极氧化铝板电解液的选择：
阳极氧化膜生长的先决条件是电解液对氧化膜具有溶解作用。然而，这并不意味着阳极氧化可以在所有具有溶解效应的电解质中生成氧化膜，或者生成的氧化膜的性质相同。

Aluminum oxide plate has rich color and modern metal appearance, so more and more product metal shells use oxidation process to achieve beautiful and useful results. Aluminum oxide plate is widely used in signs, mobile electronic equipment, household appliances, construction, decoration and other industries. The color of aluminum oxide plate is also very rich. There are natural color, black, rose gold, fog white, stainless steel, gold and other colors to choose from. Different industries can choose oxidation products with different appearance. In the sign industry, different colors can be selected according to the characteristics and needs of the products. In the application of signs, the basic colors such as nature, stainless steel color and gold are usually selected, which will make the signs look simple and generous and highlight the characteristics of the signs themselves.

Anodized aluminum plate is to place the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode for electrolysis under specific conditions and the effect of applied current.
1. General principle of oxide film formation of anodic alumina plate:
The process of using aluminum plate as anode and putting it in electrolyte solution to make its surface form alumina film by using electrolytic effect is called anodizing of aluminum plate. The cathode in the equipment is the data with high chemical stability in electrolytic solution, such as lead, stainless steel, aluminum, etc. The principle of aluminum anodizing is essentially the principle of water electrolysis. When the current passes through the cathode, hydrogen is released; On the anode, the separated oxygen is not only molecular oxygen, but also atomic oxygen (o) and ionic oxygen, which are usually indicated by molecular oxygen in the reaction. Aluminum as an anode is oxidized by the oxygen separated from it to form an anhydrous alumina film. The generated oxygen is not all the same as aluminum, and part of it is separated in a gaseous manner.
2. Selection of electrolytic solution for anodized aluminum plate:
A prerequisite for the growth of anodic oxide film is that the electrolyte should have a dissolution effect on the oxide film. However, this does not mean that anodic oxidation can produce oxide films in all electrolytes with dissolution effect or the properties of the generated oxide films are the same.
