Roller Brush Filament of PV panel cleaning robots is exposed to sunlight for long periods, making them highly susceptible to photoaging. This not only impairs cleaning efficiency but also shortens their service life. The main culprit is ultraviolet (UV) rays in sunlight, which break down the polymer chemical bonds of the brush filaments and degrade material performance.

To prevent photoaging of roller Brush Synthetic Fiber, actions can be taken from four key aspects:

Material Selection: Choose materials with excellent light resistance, such as PA66, or modified materials added with antioxidants and light stabilizers.

Production Process: Adopt co-extrusion technology to wrap the filaments with a UV-resistant protective layer, or apply surface treatments like coating or film plating.

In-Use Measures: Install sunshade devices or adjust the layout properly to reduce direct sunlight exposure.

Daily Maintenance: Clean the brush filaments regularly and replace those showing aging signs (e.g., hardening, breakage) in a timely manner.

By implementing these methods, you can effectively extend the lifespan of roller brush filaments and ensure the efficient operation of PV systems.
