1、标识的检查：平常我们看到的花纹铝板都是具有标识的，而且标识上是有产品的标准代号和许可证的。
1. Identification inspection: Usually, the patterned aluminum plates we see are labeled with the product's standard code and license.
2、氧化膜的厚度：这个是需要使用的涡流测厚仪器进行检测。
2. The thickness of the oxide film: This requires the use of professional eddy current thickness measuring instruments for testing.
3、表面质量的检查：在花纹铝板的表面除了要看清洁与否之外，我们需要看到更多的东西，比如我们应该看看铝板材是否出现了一些裂痕或者出现了一些腐蚀的现象，这些都是需要仔细的观察的才能发现的。
3. Surface quality inspection: In addition to checking the cleanliness of the patterned aluminum plate surface, we need to see more things, such as whether the aluminum plate has any cracks or corrosion phenomena, which require careful observation to discover.
4、封孔质量酸浸法：封孔的形成是在进行的阳极氧化后才形成的，如果这些封孔没有很好的处理的话，就会导致以后的铝板材被腐蚀的现象出现。
4. Sealing quality acid immersion method: The formation of sealing holes is formed after anodizing. If these sealing holes are not well treated, it will lead to corrosion of the aluminum plate in the future.
通常我们进行的检测方法是酸浸法，就是除去表面的灰尘之后，将硝酸滴到表面，进行轻轻的擦拭之后，用水洗掉硝酸，再在表面滴上紫药水，一分钟后搽干净，看看表面是否有明显的痕迹，如果有的话就说明封孔没有处理的很好。
The usual testing method we use is acid immersion, which involves removing dust from the surface, dropping nitric acid onto the surface, gently wiping it off with water, then applying purple potion to the surface. After one minute, wipe it clean to see if there are any obvious marks on the surface. If there are any, it indicates that the sealing has not been done well.
