ACP sheet (aluminium-plastic composite sheet) is coated with chemically treated aluminium sheet as surface material. Aluminum chute factory uses polyethylene plastic as core material, which is processed on special production equipment of ACP sheet. The unique properties of aluminium-plastic composite sheet determine its wide application. It can be used for building exterior walls, curtain wall panels, old building renovation, interior walls and ceiling decoration, advertising signs, display benches, cleaning and dust-proof projects. Aluminum-plastic composite board has been widely used in China, which belongs to a new type of building decoration material.
Advantages of ACP sheet:
ACP sheet is a good material for easy processing and forming. It is an excellent product for efficiency and time. It can shorten the construction period and reduce the cost. ACP sheets can be cut, grooved, bandsaw, drilled and buried. It can also be cold bending, cold rolling, riveting, screw joining or bonding, etc.
Poor bonding of ACP sheets:
Poor bonding or even degumming is a very worrying problem in the production of ACP sheet
. There are many factors contributing to this problem, including equipment and operation. Cold shrinkage deformation of core plate and deformation of aluminium coil, aluminium chute and flue gas pollution of aluminium surface in Flue-curing paint will cause poor bonding. When plastics contain low molecular chemical additives such as opening agent and smoothing agent, the bonding force of the adhesive layer will be slowly destroyed and degumming will occur. Therefore, for the phenomenon of poor bonding, we need to analyze the specific problems and find out the crux to solve them.
