The aluminium composite panel manufacturer tells us that when producing curtain wall aluminium composite panels,
different compounding methods can be used, let's take a look at them specifically.
One is the co-extrusion composite method, it is the polyethylene particles into the main extruder melt, plasticization,
while the bonding resin into the auxiliary extruder melt, fully activating the maleic anhydride reaction group,
bonding resin through the shunt mechanism to cover the upper and lower sides of polyethylene,
forming a three-layer structure, together through the T-shaped mouth die co-extrusion, under a certain temperature, pressure, after compounding, calendering,
cooling, shaping and other processes to manufacture into Curtain wall aluminium-plastic panels. Then there is the continuous film lamination method,
which is a five-layer structure of aluminium face roll, polymer bonding film, PE core board, Kormo bonding film and aluminium bottom roll,
which are produced together in the lamination process when laminated.
There is also a step-by-step continuous method,
which is a method of producing curtain wall aluminium composite panels by extruding polyethylene plastic on an extruder and collecting it into a coil,
and then laminating it with aluminium face rolls and bottom rolls on a composite line.
