What is the composition of aluminum-plastic panels?
Aluminum-plastic composite panels are made of multi-layer composite material, the upper and lower layers of high-purity aluminum alloy plate, the middle of non-toxic low-density polyethylene (PE) core board, the front also paste a protective film. For outdoor, aluminum-plastic panels coated with fluorocarbon resin (PVDF) coating, for the interior, the front can be non-fluorocarbon resin coating.
Aluminum-plastic plate discoloration, bleaching, mainly due to improper selection of plate. Aluminum-plastic plate is divided into indoor plate and outdoor board, the two kinds of sheet surface coating is different, determines the applicable different occasions. Indoor use of the plate, the surface of the general spray resin coating, this coating can not adapt to the outdoor natural environment, if used in the outdoors, will naturally accelerate its aging process, causing discoloration bleaching phenomenon. Outdoor aluminum-plastic plate surface coating is generally used anti-aging, anti-ultraviolet ability of strong fluoroelastomer coating, this plate is expensive. Some construction units to deceive the owners to indoor use of sheet metal posing as anti-aging, corrosion-resistant high-quality fluorocarbon sheet, squeeze unreasonable profits, resulting in the use of the aluminum plate on the serious discoloration, bleaching phenomenon.
Aluminum-plastic plate is easy to process, forming a good material. But also for the pursuit of efficiency, for the time of the fine products, it can shorten the duration and reduce costs. Aluminum-plastic plate can be cut, cut, slotted, band saw, drilling, processing buried head, you can also cold bending, cold fold, cold rolling, can also riveting, screw connection or glue bonding.
