What’s The Common Problems of Aluminium Colour Coated Coils
Aluminum color coated coils are a popular kind of aluminum coil in decoration field. It is well known for super weather resistance and rich colors. It has relatively high requirements on the processing craft. For ensuring the quality, let’s know about the common problems first.
Surface Scratch
It is a a kind of surface defect in the production of color coated aluminum coils, which will affect the appearance of the prepainted aluminium coils and reduce the the corrosion resistance of them.
According the causes, this problem can be divided into scratches of raw materials and scratches during production processes. To avoid the entrance of the scratched aluminum substrates, checking the production quality of the previous process is very necessary.
Coating Leakage
It refers to the quality defects formed during the color coating production process of aluminum plate, which directly affects the appearance of prepainted aluminum coil and also affects the performance of prepainted aluminum coil. Therefore, it is necessary to understand the cause of leakage in the production process in order to take measures to avoid and control leakage defects.
Leakage of Bumps
It can be divided into two cases: pit leakage and bump leakage. Impurities on the raw material can cause bump leakage after coating. The solution is to check the cleaning quality of the raw materials before entering the coating process.
To solve the pit leakage, it is necessary to clean the rollers of the color coating production line before starting production, to prevent the appearance of debris on the aluminum color coating.
A big and experienced color coated coil manufacturer has strict processing requirements and does testing during the whole process. The defect probability is very little. If you like to buy color coated aluminum coil wholesale, Haomei Alu is a good choice for you.
