When choosing a laminated aluminum-plastic panel, the user should conduct a sample test to determine whether the selected viscosity and the adhesive of the selected surface protective film are suitable for the surface coating of the decorative material, because the adhesive of the surface protective film is not a general-purpose self-adhesive .
1. Aluminum-plastic panels can be divided into polyester aluminum-plastic panels and fluorocarbon aluminum-plastic panels according to the material of the paint. Each type can be roughly divided into metallic paint and non-metallic paint. Due to the difference in paint material and structure, different requirements are put forward on the thickness and viscosity of the protective film glue.
2. In use, if the glue property of the protective film is not selected properly or the glue quality is unstable, it will cause many problems to the user, such as not sticking, curling, or not being torn off within the shelf life after sticking.
3. The viscosity of the selected surface protective film should be determined according to the smoothness of the material surface. The surface of the material is smooth and smooth. The viscosity of the selected protective film should be low, the surface of the material should be rough, and the particles on the coating surface should be rough. The viscosity of the selected protective film should be high. On the contrary, if you choose to use it improperly, it will cause the phenomenon that the paste is not firm or cannot be removed.
4. For a given surface, the appropriate glue and viscosity should be selected, and the subsequent processing steps are the key to determining the size of the viscosity. Subsequent processing generally includes bending and stamping. Generally, a low-viscosity protective film is used for smooth surfaces with a viscosity of 0.9N/cm; a medium-viscosity protective film is used for medium-rough surfaces with a viscosity of 1.2N/cm.
For the use of laminated aluminum-plastic panels, it is recommended that you still pay attention to the correct way of use, and also pay attention to choosing products with guaranteed quality. The above is the relevant introduction of the precautions for the selection of film aluminum-plastic panels that Youwoxing will take you to know.
