The principle of the single-sided color steel magnesium composite duct is primarily based on its special structure and material composition. This duct utilizes a fire-resistant core material made of magnesia (MgO), magnesium sulfate (MgSO4), water (H2O), and modifiers, which are reasonably configured into a fireproof board. The core is then coated with steel plates and assembled using metal components. This design ensures not only excellent fire resistance but also certain structural strength and durability. Specifically:

Fire-resistant core material: A combination of light-burned magnesium oxide, magnesium sulfate, water, and modifiers forms a fire-resistant board. This material effectively prevents the spread of flames when attacked by fire, protecting the internal pipeline from damage.

Sheet metal cladding: The outer covering of steel plates on fire-resistant core materials not only enhances the structural strength of the duct, but also provides an additional fire-resistant layer, further improving the fire resistance of the duct.

Metal Component Fabrication: Fabrication of metal components ensures that the joints of ducts have excellent sealing and stability, guaranteeing the normal operation and safety of the duct system.

In summary, the principle of the single-sided color steel magnesium composite ductwork lies in its unique material combination and structural design, which achieves excellent fire resistance and structural strength. This ensures that during emergencies such as fires, the duct system can maintain stable operation, providing the building with reliable ventilation and smoke exhaust channels.
