Quality Analysis for aluminum composite panels

iscoloration and decoloration
Discoloration and discoloration due to the improper selection of the materials. Aluminum composite panel are divided into indoor panels and outdoor panels. The surface coatings of them are different, which determines the different occasions for which they are applicable. The in door board are usually with PE coating and it can not adapt to the harsh outdoor environment. If it is used outdoors, it will accelerate aging and cause discoloration and discoloration. The indoor ACP is generally with PE coating, which is with high anti-aging and uvioresistant. The prices will be more expensive. Some suppliers sell indoor ACP and claim that they are outdoor wall panel to make huge profit, which causing serious discoloration and discoloration in the project.

Tackless and peeling
The Tackless and peeling of the aluminum composite panel is mainly due to improper selection of the binder. Usually silicone rubber is used as ideal binder for panel. In the past, Silicone rubber are mainly imported from other countries. The prices are too expensive to be acceptable by many factories. Only those high-rise buildings with expensive curtain wall projects dare to pay attention. By now, many factories mass produce the silicone rubbers and the prices are fair enough for people. Currently suppliers will recommend those ACP bonded with special quick-drying glue. However,This kind of glue can only be used indoors. It can cuase tackless and peeling using outdoors due to the unstable environment.

Deformation and drumming on the surface
People can always see the surface deformation and drumming on the surface of those big landscape projects, small facade renovation projects, as well as on large high-rise buildings. In fact, the problem is mainly on the base sheet, and secondly, the quality of the aluminum sheet. The aluminum sheet in high-density boards, wood boards, which suppliers recommend, are fragile in outdoors. After being blown by the wind, sun, and rain, deformation is inevitable. It can be seen that the ideal outdoor base material should be rust-proofed, and the angle steel and square steel tube are able to be formed into a skeleton, which make perfect base materials. And aluminum will be more idealistic material for the base. The prices may be the same but it ensure the quality of the project.
