铝卷在我们的生活中被广泛使用，各方面的性能可见的好，但是面对市面上数量繁多的铝卷，质量方面是不一样的，有好有坏，那么如何通过外观厚度来辨别铝卷质量呢？
　　Aluminum coil is widely used in our life, the performance of all aspects of the visible good, but in the face of a large number of aluminum coil on the market, the quality is not the same, there are good and bad, so how to identify the quality of aluminum coil through the appearance of thickness?
　　铝卷的质量可以通过外观，平面度和厚度公差来区分。优质铝卷表面无油，无色差和划痕，这可以通过购买铝卷的外观来区分，因此建议没有购买铝卷经验的用户可以通过很简单的表面来区分铝卷的质量。
　　Aluminium coil quality can be distinguished by appearance, flatness and thickness tolerances. High quality aluminum coil surface oil free, no color difference and scratch, which can be distinguished by buying the appearance of aluminum coil, so it is recommended that users who do not buy aluminum coil experience can distinguish the quality of aluminum coil by very simple surface.
　　铝卷生产厂家提醒大家，选择高质量的铝卷或展平铝卷，散布在地面上，可以看到铝卷是否有起伏的波浪。高质量的铝卷已得到纠正，没有明显的波纹。厚度需要使用的千分尺进行测量。完成上述步骤后，您可以选择优质铝卷。
　　Aluminum coil manufacturers remind you to choose high-quality aluminum coil or flat aluminum coil, scattered on the ground, you can see whether the aluminum coil has ups and downs. High quality aluminium coil has been corrected without noticeable ripple. The thickness should be measured with a professional micrometer. After completing the above steps, you can choose high quality aluminum coil.

　　此外，阳极氧化后的铝卷表面存在许多空隙，如果未密封或密封不好，则铝型材的耐腐蚀性会降低。铝的表面易于自然产生致密而牢固的保护膜，可以很好地保基材不受腐蚀。通过人工阳极氧化和着色，可以获得具有良好铸造性能的铸造铝合金或具有良好加工塑性的变形铝合金。
　　In addition, there are many voids on the surface of the anodized aluminum coil, and if it is not sealed or poorly sealed, the corrosion resistance of the aluminum profile will be reduced. The surface of aluminum is easy to naturally produce a dense and strong protective film, which can well protect the base material from corrosion. By artificial anodic oxidation and coloring, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained.
　　如何通过外观厚度来辨别铝卷质量？以上便是问题的相关解答内容了，大家还要注意铝卷的存放是有要求的，具体的事项可以来网站进行咨询了解！
　　How to distinguish the quality of aluminum coil by its appearance thickness? The above is the relevant answers to the problem, we should also pay attention to the storage of aluminum coil is required, specific matters can come to the website for consultation!
