氧化鋁板就是將鋁板經(jīng)過相應(yīng)處理使其表面形成一層氧化膜，我們稱為氧化鋁板，根據(jù)工藝不同氧化鋁板還分為陽極氧化鋁板和化學(xué)氧化鋁板。
　　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.
　　陽極氧化鋁板是將鋁板置于相應(yīng)電解液(如硫酸、鉻酸、草酸等)中作為陽極，在特定條件和外加電流作用下，進(jìn)行電解。陽極的鋁板氧化，表面上形成氧化鋁薄層 ，其厚度為5～20微米 ，硬質(zhì)陽極氧化膜可達(dá)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.
　　化學(xué)氧化鋁板就是鋁板在弱堿性或弱酸性溶液中，部分基體金屬發(fā)生反應(yīng)，使其表面的自然氧化膜增厚或產(chǎn)生其他一些鈍化膜的處理過程，常用的化學(xué)氧化膜有鉻酸膜和磷酸膜，它們既薄吸附性又好，可進(jìn)行著色和封孔處理。
　　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.
　　陽極氧化和化學(xué)氧化因?yàn)楣に嚥煌a(chǎn)生的氧化膜性能也不一樣，化學(xué)氧化膜與鋁陽極氧化膜相比，化學(xué)氧化膜要薄得多，抗蝕性和硬度比較低，而且不易著色，著色后的耐光性差，所以鋁板著色與配色僅介紹陽極化處理。
　　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.
　　氧化鋁板的優(yōu)勢及特點(diǎn)：
　　Advantages and characteristics of alumina sheet:
　　1.具有良好的加工性：陽極氧化鋁板，硬度適中，既可折彎成型還可以進(jìn)行連續(xù)性高速?zèng)_壓，非常適合企業(yè)產(chǎn)品的加工，由于陽極氧化鋁板裝飾性強(qiáng)，企業(yè)產(chǎn)品生產(chǎn)出后無需再進(jìn)行表面的工藝處理，對(duì)于企業(yè)而言，可以大大降低生產(chǎn)成本和生產(chǎn)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：標(biāo)準(zhǔn)厚度氧化膜（3μm）的陽極氧化鋁板室內(nèi)使用長期不變色，不腐蝕，不氧化，不生銹。加厚氧化膜（10μm）的陽極氧化鋁板可使用于室外，可長期暴露于太陽光線下不變色。

                               
　　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.外表美觀，金屬感強(qiáng)：經(jīng)陽極處理的鋁板表面硬度高，可達(dá)寶石級(jí)，抗刮性好，表面無油漆覆蓋，保留鋁板金屬色澤，突出現(xiàn)代金屬感，提高產(chǎn)品檔次和附加值。
　　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.環(huán)保，耐高溫：氧化鋁板是純金屬制品，表面無其他化學(xué)物質(zhì)，600度高溫下可以做到不燃燒，不產(chǎn)生有毒氣體，完全符合消防環(huán)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，使用范圍廣：氧化鋁板，不留手印，不會(huì)有污點(diǎn)痕跡，容易清洗，不產(chǎn)生腐蝕斑點(diǎn)。可廣泛應(yīng)用于金屬鋁天花板，幕墻板，鋁塑面板，防火板，蜂窩鋁板，鋁單板，電器面板，櫥柜面板，家具面板等。陽極氧化鋁板還是機(jī)械零件，飛機(jī)汽車部件，精密儀器及無線電器材，汽車裝飾等行業(yè)的好材料。
