The thickness of aluminum composite panel interiors
The thickness of upper panel is 0.20mm, its smallest thickness is at least 0.10mm, its total thickness is 3mm. Its coating uses polyester coating and acrylic coating.
Installation precautions of aluminum composite panel interiors
(1) Connection of rivet
Aluminum composite panel can be connected with panel or other materials by suitable rivet. For outdoor or high humidity areas, it should use self-plugging rivet with stainless steel core to avoid influencing the board of aluminum composite panel by corrosion, if you use rivet with iron core, it must be extracted after connecting. Countersunk head rivet can just used indoors.
(2) Screw fastener
Fixed part should be used indoors
The connection indoors can be used by different cephalic steel plate or screws. Those screws are not allowed to have thermal expansion displacement with aluminum composite panel.
Countersunk head rivet can be used for fixing aluminum composite panel, aluminum face can be put into panel by countersunk hole method, its hole in aluminum panel is bigger than the diameter of screw rod.
(3) Plastic welding ( just used for PE core material)
The connection of plastic by hot-air can also be used for the connection of aluminum composite panel, using heated air to melt polyethylene core and plastic welding rod of aluminum composite panel by electrically heated welding gun, then connecting them after cooling, the following is the condition for good welding quality:
a. Preparing good edge interface
b. Clean hot air
c. Correct welding temperature.
d. Correct contact pressure.
e. Welding speed
