氧化铝板就是将铝板经过相应处理使其表面形成一层氧化膜，我们称为氧化铝板，根据工艺不同氧化铝板还分为阳极氧化铝板和化学氧化铝板。
　　Alumina plate is a layer of oxide film formed on the surface of aluminium plate after corresponding treatment. We call it alumina plate. According to different processes, alumina plate can also be divided into anodic alumina plate and chemical alumina plate.
　　阳极氧化铝板是将铝板置于相应电解液(如硫酸、铬酸、草酸等)中作为阳极，在特定条件和外加电流作用下，进行电解。阳极的铝板氧化，表面上形成氧化铝薄层 ，其厚度为5～20微米 ，硬质阳极氧化膜可达60～200微米 。
　　Anodic alumina plate is an anode made of aluminium plate in corresponding electrolyte (such as sulphuric acid, chromic acid, oxalic acid, etc.) under specific conditions and applied current. A thin layer of alumina is formed on the surface of the anode when the aluminium plate is oxidized. Its thickness is 5-20 microns, and the hard anodic oxide film can reach 60-200 microns.
　　化学氧化铝板就是铝板在弱碱性或弱酸性溶液中，部分基体金属发生反应，使其表面的自然氧化膜增厚或产生其他一些钝化膜的处理过程，常用的化学氧化膜有铬酸膜和磷酸膜，它们既薄吸附性又好，可进行着色和封孔处理。
　　Chemical alumina plate is a process in which some matrix metals react in weak alkaline or acidic solution to thicken the natural oxide film on its surface or produce other passive films. The commonly used chemical oxide films are chromic acid film and phosphoric acid film, which are thin and adsorbable, and can be colored and sealed.
　　阳极氧化和化学氧化因为工艺不同，所产生的氧化膜性能也不一样，化学氧化膜与铝阳极氧化膜相比，化学氧化膜要薄得多，抗蚀性和硬度比较低，而且不易着色，着色后的耐光性差，所以铝板着色与配色仅介绍阳极化处理。
　　Anodic oxidation and chemical oxidation have different properties because of different processes. Compared with aluminium anodic oxidation, chemical oxidation film is much thinner, less resistant to corrosion and hardness, and is not easy to be colored. The light resistance after coloring is poor. Therefore, the coloring and matching of aluminium plate only introduces anodic treatment.
　　氧化铝板的优势及特点：
　　Advantages and characteristics of alumina sheet:
　　1.具有良好的加工性：阳极氧化铝板，硬度适中，既可折弯成型还可以进行连续性高速冲压，非常适合企业产品的加工，由于阳极氧化铝板装饰性强，企业产品生产出后无需再进行表面的工艺处理，对于企业而言，可以大大降低生产成本和生产周期。
　　1. Good processability: Anodic alumina plate, with moderate hardness, can be bended and formed and can be punched continuously at high speed. It is very suitable for the processing of enterprise products. Because of its strong decoration, there is no need for surface treatment after the production of enterprise products. For enterprises, the production cost and production cycle can be greatly reduced.
　　2.具有持久的耐候性：标准厚度氧化膜（3μm）的阳极氧化铝板室内使用长期不变色，不腐蚀，不氧化，不生锈。加厚氧化膜（10μm）的阳极氧化铝板可使用于室外，可长期暴露于太阳光线下不变色。

                               
　　2. Durable weatherability: standard thickness of oxide film (3 micron) of anodic alumina plate indoor use for a long time does not change color, corrosion, oxidation, rust. Anodic alumina sheets with a thicker oxide film (10 micron) can be used outdoors and remain colourless under long-term exposure to sunlight.
　　3.外表美观，金属感强：经阳极处理的铝板表面硬度高，可达宝石级，抗刮性好，表面无油漆覆盖，保留铝板金属色泽，突出现代金属感，提高产品档次和附加值。
　　3. Beautiful appearance, strong metal sense: the surface hardness of the anodized aluminium plate is high, up to gem grade, good scratch resistance, no paint covering, retaining the metal color of the aluminium plate, highlighting the modern metal sense, improving product grade and added value.
　　4.环保，耐高温：氧化铝板是纯金属制品，表面无其他化学物质，600度高温下可以做到不燃烧，不产生有毒气体，完全符合消防环保要求。
　　4. Environmental protection, high temperature resistance: alumina plate is pure metal products, no other chemicals on the surface, 600 degrees high temperature can be achieved without burning, no toxic gases, fully in line with the requirements of fire protection and environmental protection.
　　5.耐污染，使用范围广：氧化铝板，不留手印，不会有污点痕迹，容易清洗，不产生腐蚀斑点。可广泛应用于金属铝天花板，幕墙板，铝塑面板，防火板，蜂窝铝板，铝单板，电器面板，橱柜面板，家具面板等。阳极氧化铝板还是机械零件，飞机汽车部件，精密仪器及无线电器材，汽车装饰等行业的好材料。
　　5. Pollution-resistant, widely used: alumina board, no fingerprints, no stains, easy to clean, no corrosion spots. It can be widely used in metal aluminium ceilings, curtain wall panels, aluminium-plastic panels, fire-proof panels, honeycomb aluminium panels, aluminium veneers, electrical panels, cabinet panels, furniture panels, etc. Anodic alumina plate is also a good material for machinery parts, aircraft and automobile parts, precision instruments and radio equipment, automobile decoration and other industries.
