The principle of fire-resistant wrapping for industrial integrated calcium silicate composite boards mainly relies on its unique structure and material combination, achieving efficient fire resistance through multi-layer protection and connection methods.
The design of the fire-resistant cladding for industrial integrated calcium silicate composite board ducts includes components such as the duct body, fire-resistant insulation boards, connecting flanges, L-shaped angle brackets, and connecting plates. The fire-resistant insulation boards are overlaid on the outer side of the duct body, secured in place with L-shaped angle brackets and connecting plates, ensuring a firm installation. This design not only enhances the overall fire resistance but also strengthens the structural stability, capable of adapting to complex transportation environments. Specifically:
Fire-resistant insulation board: Provides primary fire protection, preventing direct contact with flames and high temperatures, reducing heat transfer.
L-shaped angle and connecting plate: These components securely fasten the fire-resistant thermal insulation board to the outer side of the air duct base, forming a complete fire-resistant covering layer.
Flange Connection: Used to connect two ducts or ducts to other equipment, also enhancing overall stability.
Shading Plates and Rivetless Riveting: Further enhances the tightness of connections and the stability of structures.
Additionally, this composite board utilizes a mechanized automatic lamination process, featuring fire-resistant, asbestos-free fiber-reinforced calcium silicate board and rock wool board as the core layer, with color steel plates (thickness not less than 0.35mm) as the protective layer on the outer surface, and aluminum foil on the inner surface. This design achieves efficient fire resistance and excellent thermal insulation. It is not only suitable for industrial environments but also for other applications requiring fire protection, such as interior decoration and partitions in buildings.
