Daylighting tile/sheet/panel installed on the roofing and buildings wall, it's used under the sun everyday. Suffering the sunshine and cold weather. Why the daylight aging easily?
1. Sunlight. When FRP is used in lighting tiles, ultraviolet absorbers are added to the outer surface to absorb harmful light waves. In addition, the role of coupling agents can also be considered. The service life of FRP after treatment must be required in the project.
2. In the environment of high temperature and heavy rain, the bending strength will decrease due to the moisture entering the resin glass fiber interface.
The performance of lighting sheet aging:
1. The glass fiber reinforced plastic lighting sheet loses its luster and the light transmittance is reduced. It looks foggy.
2. The lighting tiles are partially peeled off and the fibers are exposed. It shows that the lighting sheet has been severely corroded and aged. At this time, protective measures such as repair or resin coating should be taken.
3. The lighting sheet swells and partially delaminates. It shows that the corrosion is serious and has been destroyed, and this situation is already very dangerous. It should be determined whether it can be repaired according to the specific situation.
How does the daylighting wave plate resist aging:
It is composed of high-performance upper film, reinforced polyester and glass fiber. The upper film must have good anti-ultraviolet and anti-static properties. The anti-ultraviolet is to protect the polyester of the daylighting glass fiber reinforced plastic sheet from yellowing, aging and premature loss of light. Antistatic is to ensure that the dust on the surface is easily washed away by rain or blown away by the wind, and maintain a clean and beautiful surface.
