          Patterned aluminum plate is an aluminum product that forms various patterns on the surface through rolling processing on the basis of aluminum plate. It is widely used and mainly used in packaging, construction, curtain walls, and other aspects. So, how to detect the quality of patterned aluminum plate wire drawing


          Patterned aluminum plate


          Identification inspection: Usually, the patterned aluminum plates we see are labeled with the product's standard code and license.



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


          Surface quality inspection: In addition to checking for cleanliness, we need to see more on the surface of patterned aluminum plates. For example, we should check if there are any cracks or corrosion on the aluminum plate, which requires careful observation to discover.


          Sealing quality acid immersion method: The formation of sealing holes is only after anodizing. If these sealing holes are not well treated, it will lead to corrosion of the aluminum plate in the future.


          The usual method for testing patterned aluminum plate wire drawing is the acid immersion method. After removing the surface dust, nitric acid is dropped onto the surface, gently wiped, washed off with water, and then dropped purple solution on the surface. After one minute, it is wiped clean to see if there are any obvious marks on the surface. If there are any, it indicates that the sealing hole has not been treated well.
