How to inspect the quality of patterned aluminum sheet drawing? 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 should the quality of patterned aluminum plate wire drawing be tested?
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 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 dropping purple solution on the surface, and wiping it clean after one minute 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.
