Black and white aluminum-plastic plate protective film: special protective film for polyester roller coating series aluminum-plastic plate, delayed plate is affected by ultraviolet light. Transparent aluminum-plastic board protective film: special protective film for patterned aluminum-plastic board, easy to view the layout pattern. Classic aluminum-plastic board protective film: laser, PVC, and special protective film for aluminum-plastic board with special instant surface treatment, can protect the board from chemical reaction with the glue used by customers.
The general quality of the protective film of the aluminum composite panel can be guaranteed for half a year to two years. But there are certain prerequisites, that is, the aluminum composite panel with the protective film can be stored under certain conditions: suitable temperature and humidity, and avoid direct sunlight. In the process of use, if the glue properties of the protective film are improperly selected or the glue quality is unstable, it will bring many problems to the user, such as not sticking, warping or not tearing off within the shelf life after sticking.
The aluminum composite panel should be torn off as soon as possible after the decoration is completed. If the time is too long, the protective film of the aluminum composite panel will be weathered and dried and difficult to absorb. You can scrub the surface of the double-layer aluminum composite panel protective film with hot water, and then slowly tear it off. Clean up. The discoloration and discoloration of aluminum composite panels are mainly caused by improper selection of panels. Aluminum-plastic panels are divided into indoor panels and outdoor panels. The surface coatings of the two panels are different, which determines their application in different occasions.
The surface of the board used indoors is generally sprayed with a resin coating. This coating cannot adapt to the harsh outdoor natural environment. If it is used outdoors, it will naturally accelerate its aging process, causing discoloration and discoloration. The surface coating of outdoor aluminum-plastic panels is generally made of polyfluorocarbon resin coating with strong anti-aging and anti-ultraviolet ability, which is expensive. Some construction units deceived the owners, pretending to be anti-aging and anti-corrosion high-quality fluorocarbon sheets for indoor use, to squeeze unreasonable profits, thus causing serious discoloration and discoloration of the aluminum sheets used in the project.
The glue opening and falling off of the aluminum composite panel are mainly caused by the improper selection of the binder. As an ideal binder for outdoor aluminum composite panel projects, silicone adhesive has unique advantages. In the past, my country's silicone rubber mainly relied on imports, and its value was prohibitive for many people. Only those expensive curtain wall projects on high-rise buildings dared to care.
