◆Product composition of PIR Foam Aluminum Duct
This air duct is mainly composed of two parts. The internal polyisocyanurate (PIR) foam is the core insulation layer, which is made by the reaction of isocyanate with polyether under the action of a catalyst. PIR foam has a unique molecular structure and strong stability.
The exterior is made of aluminum material, with common ones being 60-80-micron aluminum foil or 150-200-micron aluminum Sheet. Aluminum material not only provides a certain strength for air ducts, but also has good moisture-proof and corrosion-resistant properties.
◆Performance advantage of PIR Foam Aluminum Duct
1. Excellent fire resistance: PIR foam itself has a relatively high fire resistance rating, usually reaching the B1 flame retardant standard, which can significantly enhance the safety of ventilation systems and is suitable for places with strict fire protection requirements.
2. Excellent mechanical properties: The air duct has high strength and pressure resistance, can withstand certain external force impacts and internal wind pressure, is not prone to deformation, ensures normal use in complex environments, and has a long service life.
3. Excellent air tightness: The structural design of the product endows it with outstanding air tightness, which can effectively reduce air leakage, ensure the efficient operation of the ventilation system, and avoid problems such as energy loss and poor ventilation effect caused by air leakage.
◆ Installation and maintenance of PIR Foam Aluminum Duct
Installation Key Points:
Modular splicing with adhesives/fasteners; seal joints with high-temp tapes; cut to size for non-standard sections.
Routine Maintenance:
Wipe aluminum surface (avoid abrasive cleaners); quarterly air leakage tests (re-seal if needed); touch up aluminum scratches with anti-corrosion paint.
Long-Term Care & Precautions:
Check PIR core for damp/mildew every 2–3 years (replace damaged parts); avoid impacts/heavy loads; keep flammables away, no unapproved modifications.
