Phenolic composite air duct is a kind of air duct made of phenolic foam as the middle layer and embossed aluminum foil as the inner and outer layers. This type of air duct has high temperature resistance and can withstand long-term use in high-temperature environments without embrittlement, decomposition, or melting. In addition, phenolic composite air ducts also have various advantages such as corrosion resistance, anti mold and antibacterial properties, good insulation, good noise reduction, light weight, long service life, convenient installation, hygiene and aesthetics.
The main production process of phenolic composite air ducts includes steps such as layout and marking, sheet forming, aluminum foil bonding, processing and manufacturing, and inspection and packaging. In the production process, it is necessary to strictly control various parameters and processes to ensure the quality and performance of the product.
Phenolic formaldehyde composite air ducts are widely used in various places that require ventilation, such as power plants, petrochemicals, metallurgy and other high-temperature and highly corrosive industrial places, as well as commercial places that require high air purification and comfort, such as shopping malls, office buildings, hospitals, etc. In addition, it is also suitable for ventilation and smoke exhaust in underground parking lots, subways, highway tunnels, and other places.
However, phenolic composite air ducts also have some limitations. For example, its outer skin is made of aluminum foil, which may not be suitable for acid-base air conditioning systems; Meanwhile, its resistance is relatively low and may not be suitable for high-pressure systems. Therefore, when choosing to use it, it is necessary to comprehensively consider the specific usage environment and requirements.
Overall, phenolic composite air ducts are gradually becoming one of the mainstream products in the air duct market due to their excellent performance and wide application areas.
