How to check the quality of patterned aluminum plate?
Nov 09, 2020

Patterned aluminum sheet is based on aluminum sheet, which forms various patterns on the surface after calendering. It is widely used and mainly used in packaging, construction, curtain walls, etc. So, how to check the quality of drawing aluminum plate?

1. Inspection of the logo: The patterned aluminum plates we usually see are all labeled, and the logo has the standard code and license of the product.

2. The thickness of the oxide film: This requires the use of a professional eddy current thickness measuring instrument for testing.

3. Inspection of the surface quality: In addition to the cleanliness of the surface of the patterned aluminum plate, we need to see more things, for example, we should check whether the aluminum plate has some cracks or some corrosion. These all require careful observation to discover.

4. Sealing quality acid leaching method: The formation of the sealing is formed after the anodic oxidation. If these sealings are not well treated, it will cause the subsequent corrosion of the aluminum plate.

Usually the detection method we carry out is the acid leaching method, which is to remove the dust on the surface, drop the nitric acid on the surface, wipe it gently, wash off the nitric acid with water, and then drop the purple syrup on the surface, and wipe it off after one minute. See if there are obvious traces on the surface. If there are any, it means that the sealing is not done well.
