Composite Material For Air Ducts
This Composite Material For Air Ducts adopts a multi-layer composite structure: The substrate surface layer takes aluminum foil/steel plate as the framework to form a high-strength matrix, with a maximum operating temperature of 80℃; the insulation layer is made of closed-cell foamed polyurethane, with a thermal conductivity as low as 0.022 W/(m·K), saving 30% energy compared with traditional thermal insulation materials and effectively reducing the risk of air duct condensation; the inner layer of the functional coating is an antibacterial nano-coating with an antibacterial rate > 99%, and the outer layer is covered with a weather-resistant PVDF film that can resist ultraviolet rays and acid-alkali erosion, making it suitable for humid or industrially polluted areas.
The Advantages of Composite material for air ducts
Ultimate lightweight: With a density only 1/5 that of traditional galvanized steel sheets, it significantly reduces building structural load, as well as installation energy consumption and transportation costs.
Whole-life cycle economy: Its anti-corrosion and anti-aging properties extend the service life to more than 20 years (the average service life of traditional materials is 8-12 years), reducing the comprehensive maintenance cost by over 40%.
Dual certification for environmental protection and safety: It adopts a formaldehyde-free formula, meets flame-retardant standards, produces low smoke and no toxicity when burned, and ensures the safety of indoor air quality.
Comparison with Traditional Materials: All-round Performance Leap
| Performance Indicator | Duct Composite Material | Galvanized Steel Sheet | Inorganic Fiberglass Reinforced Plastics |
|---|---|---|---|
| Installation Cycle | 3 - 5 days/100㎡ | 7 - 10 days/100㎡ | 5 - 8 days/100㎡ |
| Thermal Conductivity | 0.022W/(m·K) | 50.2W/(m·K) | 0.06W/(m·K) |
| Resistance to Mold Growth | Grade 0 (No growth) | Grade 3 (Obvious growth) | Grade 2 (Slight growth) |
| Recycling Rate | Detachable for recycling and regeneration | Requires paint removal treatment, 60% recycling rate | Non - renewable |
This Composite material for air ducts breaks the industry pain points of "being unable to achieve both strength and lightweight" and "difficult to balance thermal insulation and fire resistance" through material innovation. It has been applied in over 2000 large-scale projects worldwide, including benchmark projects such as GOLD COAST UNIVERSITY HOSPITAL and Baoji High-Speed Railway, and has become the preferred material for the ventilation systems of green buildings.
