Several factors influence the quality of aluminum-plastic panels. Firstly, let's discuss the main factors affecting the appearance quality, which include: the quality of the paint used; whether steel or rubber rollers are employed; and the control of temperature during baking. Moving on to the factors impacting the intrinsic quality of aluminum-plastic panels, these are: the quality of the aluminum coil, the quality of the plastic, the quality of the polymer film, and the production equipment.
Furthermore, the cleaning and coating quality of aluminum-plastic panels directly affect the composite quality of the panels. This is because the aluminum-plastic panels must first be cleaned to remove surface oil and impurities, forming a dense chemical layer on the surface to facilitate excellent bonding of the polymer film, thereby ensuring high-quality finished products.
However, some manufacturers do not strictly control the temperature, concentration, processing time, and replacement of the treatment solution during the pretreatment process of aluminum-plastic panels, which affects the cleaning quality. Consequently, this will undoubtedly impact the quality of the aluminum-plastic panels and further reduce their peel strength.。
