1. Discoloration and fading of aluminum veneer curtain walls:
Discoloration and fading of aluminum veneer curtain walls are mainly caused by improper selection of coatings. The coatings of aluminum veneers are divided into indoor and outdoor use. The two different coatings determine the use occasions of aluminum veneers. Ordinary coatings, polyester powder coatings, and polyester paints are generally used for indoor use; these three coatings cannot adapt to the harsh natural environment outdoors. If used outdoors, they will naturally shorten the life of the aluminum veneer and accelerate its aging, causing discoloration and fading.
The surface coating of the outdoor aluminum veneer curtain wall will use some high-quality anti-aging and anti-corrosion coatings, such as: fluorocarbon two-layer, fluorocarbon three-layer, etc.; but this kind of aluminum veneer is slightly expensive. Some construction units deceive the owners and use indoor aluminum veneers to pretend to be high-quality outdoor aluminum veneer curtain walls that are anti-aging and corrosion-resistant in order to squeeze unreasonable profits, thus causing the aluminum veneers on the aluminum veneer curtain wall project to discolor and discolor.
2. Deformation of aluminum veneer curtain wall:
There are many reasons for the deformation of aluminum veneers; this may be a problem with the aluminum veneer plate itself. High-strength and high-quality plates are required to process aluminum veneers to produce high-quality aluminum veneer curtain walls. Improper plate selection will inevitably cause the aluminum veneer curtain wall to deform after being exposed to wind, sun, and rain during use. Another reason for deformation may be that the aluminum veneer is not well protected during transportation, causing the aluminum veneer to deform.
3. The gap between the aluminum veneer curtain wall is large and inappropriate:
Because the aluminum veneer curtain wall is measured on site by the designer and then the overall installation of the aluminum veneer is designed, the on-site measurement of the aluminum veneer curtain wall is very important. If the size is accidentally wrong, it will cause the aluminum veneer curtain wall project to have large gaps or inappropriate installation.
