Analysis of common quality problems in aluminum curtain wall projects | HLCALUMINIUM

1. Discoloration and decoloration of aluminum composite panels: 

The discoloration and decolorization of aluminum composite panels are mainly caused by the improper selection of panels. Aluminum composite panels are divided into indoor panels and outdoor panels, and the surface coating of the two types of panels is different, which determines their application to different occasions. The surface of the panels used indoors is generally sprayed with resin coating, which cannot adapt to the harsh natural environment outdoors, and if used outdoors, it will naturally accelerate the aging process and cause the phenomenon of discoloration and decolorization. Outdoor aluminum composite panel surface coating is generally selected to anti-aging, anti-UV ability of fluorocarbon resin coating, the price of this plate is expensive. Some construction units deceive the owner to use the indoor plate as the anti-aging and anti-corrosion quality fluorocarbon plate to squeeze unreasonable profits, thus causing serious discoloration and decoloration of the aluminum plate used in the project.



2. Open and peeling of aluminum composite panel:   

Aluminum composite panels open and fall off, mainly due to improper selection of adhesive. As the ideal adhesive for outdoor aluminum composite panel project, silicone adhesive has unique and superior conditions. Previously, China's silicone adhesive mainly depends on imports, the price of many people deterred, only those high-rise buildings on the expensive curtain wall project to dare to ask for. Now, China's Zhengzhou, Guangdong, Hangzhou and other places have put into production different brands of silicone rubber, resulting in a big drop in prices. Now, in the purchase of aluminum composite panels, the salesman will recommend the kind of special fast-drying adhesive. This glue can be used indoors, used in the climate vagaries of the outdoor, there will be plates open glue, glue off the phenomenon.   



3. Deformation and bulging on the surface of aluminum composite panels:

The causes of deformation and drumming on the surface of aluminum composite panel are many. Previously in the construction, this kind of quality problems, we had thought that the quality of the plate itself; later, after we focus on the analysis only to find that the main problem in the paste aluminum composite plate on the grass-roots plate, followed by the quality of the aluminum composite plate itself. Dealers often provide us with the construction process of aluminum composite panel, the recommended base material is mainly high density board, woodworking board and so on. In fact, this kind of material in outdoor use, its service life is very fragile, after the wind, sun, rain, will certainly produce deformation. Since the grass-roots materials are deformed, then as the surface layer of aluminum composite panel that there is no reason to deformation? It can be seen that the ideal outdoor base material should be after rust-proof treatment angle steel, square steel pipe knotted into the skeleton is better. If conditions allow, the use of aluminum profiles as a skeleton is more ideal.   

This kind of metal materials made of the skeleton, its cost is not much higher than the wood keel, high density board, can really ensure the quality of the project.   



4. Aluminum plastic panel glue seam neatly:   

When aluminum composite panels are decorated on the surface of the building, there is generally a gap of a certain width between the panels. For the sake of aesthetic needs, generally have to fill in the gap with black sealant. In order to save time, some constructors do not use paper tape to ensure the neatness and rules of gluing, but use the protective film on the surface of aluminum composite panel as a substitute. As the aluminum composite panel is cut, the protective film will produce different degrees of tearing situation, so use it as a substitute for the protective tape, it is impossible to clean up the glue seam neatly and tidily.
