1.標識的檢查
1. identification check
平常我們看到的花紋鋁板廠家都是具有標識的，而且標識上是有產品的標準代號和許可證的。
Usually we see the pattern of aluminum plate manufacturers are marked, and the logo is the product's standard code and license.
2.表面質量的檢查
2. inspection of surface quality
在花紋鋁板廠家的表面除了要看清潔與否之外，我們需要看到更多的東西，比如我們應該看看鋁板材是否出現了一些裂痕或者出現了一些腐蝕的現象，這些都是需要仔細的觀察的才能發現的。
In addition to the surface of the planed aluminum manufacturer, we need to see more, for example, we should see if there are some cracks in the aluminum sheet or some corrosion phenomena that need to be carefully observed.
3.氧化膜的厚度
Thickness of 3. oxide film
這個是需要使用的渦流測厚儀器進行檢測。
This is a professional eddy current thickness gauge.

4.封孔的質量
The quality of 4. holes
封孔的形成是在進行的陽極氧化后才形成的，如果這些封孔沒有很好的處理的話，就會導致以后的鋁板材被腐蝕的現象出現。通常我們進行的檢測方法是酸浸法，就是除去表面額灰塵之后，將硝酸滴到表面，進行輕輕的擦拭之后，用水洗掉硝酸，再在表面滴上紫藥水，一分鐘后搽干凈，看看表面是否有明顯的痕跡，如果有的話就說明封孔沒有處理的很好。
The formation of the sealing hole is formed after the anodization of the anode. If these sealing holes are not treated well, it will lead to the corrosion of the later aluminum sheet. We usually test the method of acid leaching, that is, after removing the surface dust, drop the nitric acid on the surface, then wash the nitric acid with water and drop the purple water on the surface. After a minute, we can see if there is any obvious trace on the surface, if the fruit has some words, it shows that the sealing hole is not treated. Very good.
5.耐蝕性
5. corrosion resistance
花紋鋁板廠家這個指標也是影響到鋁板材的壽命的，我們經常使用的是滴堿的方法，使用的是氫氧化鈉溶液，主要是看氧化膜被貫穿的時間。建議在實驗室里有嚴格要求的情況下進行。。
This indicator is also affecting the life of aluminum plate, we often use the method of drop alkali, the use of sodium hydroxide solution, mainly to see the time of the oxide film through. It is suggested that there should be strict requirements in the laboratory.
