|
Linear thermal expansion coefficient |
23×10⁻⁶/℃ (highly compatible with concrete structure) |
Key parameters for controlling super-long curtain wall joints |
(1)Molecular bonding process：
Thermosetting polyurethane film lamination technology is used to form a permanent chemical bond between the 0.5-1.2mm aluminum plate and the 80-200kg/m³ rock wool core material, with a peel strength of ≥4.0N/mm (EN 14509 standard), which completely solves the cold bridge effect of traditional mechanically fixed sandwich panels.
(2)Thermodynamic optimization design：
Heat reflective barrier: The solar radiation reflectivity (TSR) of the anodized aluminum panel surface reaches 85%, reducing the surface temperature by 12-15℃ in summer
Heat conduction blocking: The three-dimensional mesh structure of rock wool fiber extends the heat conduction path by 27 times, and the thermal resistance value is R=4.35 (m²·K)/W (75mm core material)
Thermal convection suppression: closed-cell foam edge sealing technology makes the air permeability less than 0.05m³/(m·h), eliminating energy loss
Performance Matrix: Establishing a New Benchmark for Industrial Building Materials
Scenario-based solutions: from risk management to value creation
(1.)High-risk industrial protection system (taking lithium battery factory as an example)
Pain point: GB51377-2019 requires that the fire partition of the energy storage workshop be ≤2000㎡
Countermeasures: Use 100mm thick A1 grade rock wool aluminum plate to build a fire wall system
Results:
✓ The fire resistance limit of the fire isolation zone is increased to REI 180 minutes
✓ The surface resistance of the electrostatic dissipative coating is less than 1×10⁹Ω
✓ Modular installation shortens the construction period by 40%
(2.)Acoustic optimization of transportation hub (Chengdu Tianfu International Airport)
Acoustic environment target: background noise in the terminal hall ≤45dB(A)
Technical configuration:
✓ 50mm gradient density rock wool core material (surface 30kg/m³ + bottom 120kg/m³)
✓ Micro-perforated aluminum plate Helmholtz resonance structure (250-2000Hz broadband sound absorption)
✓ BIM prefabrication construction realizes precise installation of special-shaped curved surfaces
Whether it is the fire protection enclosure system of an oil refinery or the energy-saving curtain wall of a high-end commercial building, the aluminum rock wool sandwich panel will help you create a benchmark project with both safety and efficiency with its A1-level fire protection, ultra-long life, and green and low-carbon excellent performance!
