The Problem Of Neat Seams Of Aluminum-plastic Panels

When the aluminum-plastic panel is decorated on the surface of the building, there is generally a gap of a certain width between the plates. For aesthetic reasons, the gap is generally filled with black sealant. In order to save time, some construction personnel do not use paper tape to ensure the neatness and regularity of glue, but use the protective film on the surface of the aluminum-plastic panel as a substitute. Since the aluminum-plastic panel will produce different degrees of tearing when the protective film is cut, it is impossible to use it as a substitute for protective tape, and it is impossible to clean up the glue seam.
Common quality problems in the process of aluminum-plastic panel composite and their solutions
There are two main aspects of the quality problems often occurring in aluminum-plastic panels, one is the quality of coating; The second is composite quality. The coating quality problem appears in the pretreatment and coating baking paint processing process of aluminum plate, and the composite quality problem is mainly the technical problem and management problem in the composite process. Some of these problems are influenced by a single factor, and some are influenced by multiple factors. The quality problems in the process of aluminum-plastic panel composite mainly include board bubbling, board surface speckle, ruffles and poor adhesion, which are analyzed and discussed below.
