Self-Cleaning Pre-Painted Aluminum Coil (TiO2 Photocatalytic Coating)

Core Advantages: Science and Technology and Economic "Double Engine"
Self-cleaning mechanism

Photocatalytic decomposition: TiO₂ nanoparticles produce reactive oxygen species (ROS) under ultraviolet light to decompose organic stains (degradation rate ≥ 95%, ISO 10678).

Super hydrophilic effect: the surface energy is < 25mN/m, and the rainwater forms a water film to wash away the inorganic dust (contact angle <5°).

Performance parameters rolling：

Environmental compliance

Decomposition of NOx/VOCs (in accordance with the EU EN 16980-1 air purification standard).

Zero-VOC coating, passed the French A indoor air quality certification.

International application scenarios
1. Curtain wall of super high-rise building
Burj 2020 Tower, Dubai (UAE):

In the Middle East high temperature sand and dust environment (50°C), the self-cleaning efficiency is > 90%, and the annual cleaning cost is saved by $1.2 million.

Passed ISO 22197-1 photocatalytic test (formaldehyde decomposition rate 98%).

One Nine Elms Eco House, London (UK):

Resistant to acid rain corrosion (pH 3.5), rain contact angle < 10°, BREEAM Excellence certification.

2. Public transport hubs
Singapore Changi Airport Terminal 5:

The curved aluminum sheet is resistant to oil stains (30% removal rate of airborne particulate matter) and the maintenance interval is extended to 5 years.

Complies with EN 13501-1 fire class A2.

Munich Central Station canopy, Germany:

Resistance to freeze-thaw cycle (-20°C~60°C), ice adhesion reduced by 50%.

3. Industrial environmental protection facilities
Exterior wall of Tokyo Garbage Disposal Center (Japan):

Decomposition of hydrogen sulfide (H₂S concentration > 50 ppm) with an odor elimination rate of 85% (JIS K 3702 test).

Los Angeles Wastewater Treatment Plant (USA):

Chloride corrosion resistant (Cl⁻ 5000ppm), salt spray test > 3000 hours (ASTM B117).

Future Trends: Smart and Green Revolution
1. Breakthrough in material properties
Quantum dot synergistic coating: 300% increase in visible light response (École Polytechnique Fédérale de Lausanne 2024 laboratory).

Self-healing microcapsules: release of TiO₂ nanoparticles after scratches (BASF 2026 mass production plan).

2. Energy collaborative innovation
BIPV integration: Transparent conductive film layer increases photovoltaic efficiency by 15% (Tesla Solar Roof V5 design).

Photocatalytic power generation: UV conversion for energy storage (University of Tokyo prototype with an efficiency of 5%).

3. Digital management
IoT cleanliness monitoring: Built-in sensors for early warning of contamination accumulation (Siemens MindSphere platform).

AI Clean Path Planning: Drones work accurately according to pollution maps (DJI Industry Application Solution).

4. Regulations drive the market
The EU's "Clean Building 2030" mandates that the coverage rate of photocatalytic materials for new buildings > 30%.

China's "dual carbon" policy subsidizes self-cleaning building materials ($50 per tonne CO₂ reduction subsidy).
