Huamei Composite Panel

Foil composite air duct is an updated product of the current traditional fiberglass air duct, and it is also a new generation evolutionary product of galvanized iron air duct. In addition to the advantages of good rigidity and strength of iron sheet ducts, aluminum foil fiberglass composite air ducts also have the characteristics of composite air ducts, which are developing rapidly, without the need for secondary insulation and sound absorption and noise reduction. The outer surface of the air duct is a colored steel plate, which overcomes the previous fatal weakness of the fiberglass air duct, which is weak in strength and easy to damage the outer wall, and takes advantage of the galvanized iron sheet. At the same time, the inner wall is a high-density glass wool board, which retains the sound-absorbing properties of the inner wall of the fiberglass air duct. advantage.
,
Phenolic foam board and aluminum foil are combined to form a sandwich panel, and then special flange accessories are added to form a phenolic composite air duct for central air conditioning ventilation. The inner and outer surfaces of the phenolic composite sandwich panel are coated aluminum foil, and the middle layer is made of phenolic foam material. Its comprehensive performance has been greatly improved, especially in terms of mechanical properties, such as bending resistance, compressive brittleness and processing performance. A major improvement that basically meets the requirements for the use of air conditioning ventilation ducts. ,
Performance advantages of a phenolic composite air duct,
Traditional air supply ducts of central air conditioners are usually made of iron sheet or fiberglass as the inner layer, wrapped with thermal insulation material, and wrapped with aluminum foil on the outermost surface, which makes the air supply duct self-contained. Major construction and installation are labor-consuming and time-consuming, with poor appearance, low air tightness and high energy consumption.
Scope of application,


Galvanized steel air ducts are widely used, but their service life is short in high-humidity environments. Fiberglass air ducts have dust-proof requirements in the basements of hospitals, food processing plants, etc. The use in places with high humidity is also limited, while phenolic aluminum foil composite air ducts can be widely used in industrial and civil buildings, hotels, hospitals, office buildings and other places with special requirements.
