Self-Cleaning Aluminum Composite Panel
Share:
Introduction:
Self-cleaning aluminum composite panels utilize nanoscale photocatalytic technology to achieve a self-cleaning effect through three key functions.
1. Light energy is converted into chemical energy, and the photodegradation function absorbs the ultraviolet rays in sunlight that can cause paint to fade. The stronger the UV radiation, the more UV rays are absorbed, and the greater the photodegradation capacity, thereby significantly reducing UV-induced damage to the paint and slowing down the rate of fading. In addition, the photodegradation capability breaks down corrosive substances in the atmosphere—such as vehicle exhaust and airborne oil contaminants—into water and carbon dioxide, effectively minimizing corrosion and discoloration of the aluminum composite panel coating under natural atmospheric conditions.
2. Anti-static properties and reduced dust adhesion: The primary components of self-cleaning aluminum composite panels are inorganic, making them less prone to static electricity. Consequently, the painted surface exhibits very weak attraction to airborne dust, which significantly reduces dust accumulation. Under natural conditions without rainfall, self-cleaning aluminum composite panels demonstrably exhibit lower dust deposition compared with non-self-cleaning panels.
3. Excellent hydrophilicity: upon contact with water, a hydrophilic film forms on the surface. Under light irradiation, the titanium dioxide surface becomes covered with hydroxyl groups, transforming it into a state with exceptionally strong affinity for water. In addition, other auxiliary materials incorporated into the self-cleaning aluminum composite panel also possess inherent hydrophilic properties, further enhancing the overall hydrophilic performance of the surface. As a result, when exposed to rain in natural environments, a hydrophilic film forms on the surface, effectively washing away residual dust and other contaminants. Compared with conventional aluminum composite panels that lack self-cleaning capabilities, the surface of self-cleaning aluminum composite panels remains free of water stains; each subsequent rainfall essentially serves as a cleaning cycle.
Features:
1. Self-cleaning function keeps the exterior walls as clean as new;
2. Sterilization and disinfection function, effectively killing or inhibiting a wide range of viruses and bacteria;
3. Surface paint protection: the self-cleaning coating blocks direct UV exposure to the substrate, effectively slowing the fading of colored pigments in curtain walls, billboards, and other outdoor applications under sunlight. This results in long-term resistance to aging, thereby extending gloss retention and service life.
4. Energy-saving benefits: The self-cleaning aluminum composite panel utilizes nanoscale photocatalytic technology, which not only reduces light pollution but also blocks 15% of total solar radiation from entering the interior, keeping indoor spaces cool and comfortable while lowering electricity consumption.
5. Air Purification: A 10,000-square-meter self-cleaning coating delivers air-purifying performance equivalent to that of 200 poplar trees. It not only decomposes inorganic pollutants but also exhibits exceptionally strong antibacterial and germicidal properties, effectively enhancing air quality within the designated area.
Purpose:
Suitable for a wide range of residential and commercial settings, including subway stations, airports, high-speed rail station halls and platforms, office buildings, shopping malls, hotels, hospitals, sports venues, exhibition centers, and more.
