1.标识的检查
1. identification check
平常我们看到的花纹铝板厂家都是具有标识的，而且标识上是有产品的标准代号和许可证的。
Usually we see the pattern of aluminum plate manufacturers are marked, and the logo is the product's standard code and license.
2.表面质量的检查
2. inspection of surface quality
在花纹铝板厂家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。
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
这个是需要使用的涡流测厚仪器进行检测。
This is a professional eddy current thickness gauge.

4.封孔的质量
The quality of 4. holes
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。通常我们进行的检测方法是酸浸法，就是除去表面额灰尘之后，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 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.耐蚀性
5. corrosion resistance
花纹铝板厂家这个指标也是影响到铝板材的寿命的，我们经常使用的是滴碱的方法，使用的是氢氧化钠溶液，主要是看氧化膜被贯穿的时间。建议在实验室里有严格要求的情况下进行。。
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.
