详情描述
The working principle of steel-faced magnesium composite duct primarily relies on its unique material properties and structural design.
Steel-faced magnesium composite ducts are equipped with a refractory insulation layer, combining the three properties of fire resistance, refractoriness, and heat insulation, and are a new type of refractory insulation material. This material not only meets the fire resistance and heat insulation requirements of building smoke exhaust ducts but also features high connection strength and easy installation. The inner and outer protective layers of the ducts are made of high-corrosion-resistant metal plates or anti-corrosion aluminum foil, with a service life of over 30 years. Moreover, the duct connection profiles are made of special angle steel flanges, further enhancing the stability and durability of the connections.
Steel-faced magnesium composite duct material is a laminated sheet made by cold rolling, hot rolling, and other processes, combining steel-based materials with high-temperature, wear-resistant, and corrosion-resistant magnesium-based composite materials. The surface is coated with a layer of glass fiber reinforced epoxy impregnating resin that provides insulation and corrosion protection using high-temperature spraying technology, followed by a coating of high-temperature wear-resistant magnesium aluminum alloy material. This material boasts excellent strength and wear resistance, as well as superior corrosion and insulation properties, ensuring stable operation and extended service life of the ducts under various environmental conditions.
In summary, the steel-faced magnesium composite duct achieves high efficiency in fire resistance, heat insulation, and corrosion resistance through its inner and outer protective layers made of fire-resistant and heat-insulating layers, high-corrosion-resistant metal sheets, or corrosion-resistant aluminum foil, along with the connection method of special angle steel flanges, ensuring the safety and reliability of ventilation and smoke extraction systems.
