The aluminum-plastic composite board is a composite material made of chemically treated coated aluminum sheet as the surface material and polyethylene plastic as the core material on the special aluminum-plastic sheet production equipment. The unique performance of the aluminum-plastic composite board itself determines its wide use: it can be used for building exterior wall, curtain wall board, old building renovation, interior wall and ceiling decoration, advertising signs, display platform, purification and dust engineering.
So, what should we pay attention to when we use aluminum composite panel?
(1) Aluminum composite panel should be stored in an appropriate way or installed in a dry and ventilated place, avoid water, and the ambient temperature is not higher than 70oC. Avoid installation in abnormal environment, such as smoke, dust, radiation, harmful gas and chemical environment.
(2) The aluminum composite panel should be laid flat during transportation or storage. In handling must make the plate 4 sides at the same time lift, do not unilateral drag, so as not to scratch the board.
(3) When grooving with grooving machine or gong machine, the round head or v-shaped flat head saw blade or milling cutter shall be used for grooving, with 0.2-0.3mm thick plastic core plate bent together with the panel to increase strength and toughness and Prevents the chemical reaction of aluminum flakes with H₂ in the air.The bending Angle is too sharp or cut injury and aluminum panel or the plastic left is too thick will cause aluminum plate fracture or paint film burst when bending.
(4) When bending the edge, the force should be uniform, one molding, do not bend repeatedly, otherwise it will make the aluminum panel fracture.
(5) In order to maintain the flatness of the aluminum composite panel and enhance its wind resistance, the aluminum composite panel should be lined with skeleton and glued with the plate after bending.
(6) When used for arc surface decoration, bending equipment should be used to bend aluminum composite panel, slowly force, so that the plate gradually reach the required surface, not in one step. The bend radius should be greater than 750px.
(7) Install the aluminum-composite panel on the same plane according to the same flow direction. Otherwise, it may cause color difference in the viewing Angle.
(8) The protective film should be removed within 45 days after the installation of aluminum composite panel, otherwise, the protective film will be aging due to long-term exposure to the sun. Tear film may cause glue phenomenon.
(9) The inner wall panel should be used indoors and should not be installed outdoors to ensure its service life.
(10) In the process of construction or use, if there is pollution on the surface of the plate, it can be gently cleaned with neutral detergent or alcohol, instead of strong acid or alkaline detergent.
Remind consumers again, different specifications of different uses of aluminum composite panel prices will be different, please understand the market before purchasing; In the process of using aluminum composite panel must pay attention to maintenance.
