Many people who use aluminum-plastic panels should know that this is a material that can have many colors, and it is used a lot in our lives, but in fact, our manufacturers have also encountered problems such as not being able to color The reason, do you know what the reason is? What are the solutions? Here is a brief introduction for you.
With the development of technology, aluminum-plastic panels are used more and more in people's lives, and the color is no longer as monotonous as before. The current aluminum-plastic panel processing can color the color you want, but when we color the aluminum-plastic panel, it is inevitable that we will encounter the situation that the color cannot be dyed, the cause and treatment of the non-coloring of the aluminum-plastic panel The methods are:
1. Insufficient anodic oxidation film thickness: The solution is to check whether the anodic oxidation process is standardized, to see whether the temperature, voltage, conductivity and other factors are stable. If there is any abnormality, please adjust the specification accordingly. If there is no abnormality, the oxidation time can be extended appropriately. Ensure that the film thickness meets the standard.
2. The selected dye has been decomposed or mildewed: at this time, the dye needs to be replaced and a suitable dye should be selected. 3. The oxidation temperature is too low, resulting in dense film: the oxidation temperature can be increased appropriately. 4. The PH value of the dye solution is too high: at this time, glacial acetic acid can be used to adjust the PH value to the standard value.
5. The workpiece is placed in the water tank for too long after oxidation: timely dyeing is advocated. If this situation has already occurred, the workpiece can be properly activated in the anodic oxidation tank or nitric acid neutralization tank before dyeing, and the effect will be very good. it is good. 6. Poor electrical conduction: Poor electrical conduction in batches may be indicated by poor contact of the anode copper rod or cathode lead plate. Pay attention to cleaning the anode copper rod and cathode lead plate to ensure good electrical conductivity.
The above is about the causes and treatment methods of the non-staining of aluminum-plastic panels. At present, aluminum-plastic panels have become a common material in the construction field, and they are widely used in decorative fields such as building exterior walls, interior walls, and advertising signs. However, as people's aesthetic requirements for decorative products are getting higher and higher, aluminum-plastic panels with single colors and rigid patterns can no longer meet production needs.
