Fiber Cement Anti-Explosion Partition Board
Fiber cement anti-explosion partition board are made of a composite of fiber-cement board and steel. Fiber-cement serves as the primary inner layer, a mixture of cement and glass fiber. Its superior strength and durability are key features of these panels. They are primarily used as explosion-proof partitions in the chemical, oil, and gas industries, as well as in safety-critical buildings such as data centers and nuclear power plants. Fiber cement anti-explosion partition board offer excellent explosion-proof properties. In the event of an explosion, they absorb and disperse the impact energy. Combined with the steel plate, they effectively resist the blast pressure and shockwave. Experienced users know that they are exceptionally lightweight yet offer high compressive, tensile, and flexural strength. Custom sizes are also available.
The full performance of fiber cement anti-explosion partition board depends on the rigid connection between the panels, keels, and the building structure, ensuring they can withstand the blast wave and prevent the panels from falling off or deforming over time.
Galvanized steel sections are primarily used, with a wall thickness of >=2.0mm and spacing <=600mm. They can bear the weight of the panels and the impact of explosions, transmitting them to the main structure.
Galvanized light steel purlins with a wall thickness of >=1.2mm and spacing <=400mm help secure the panels and ensure they are evenly loaded.
High-strength self-tapping screws (grade 8.8 or higher) and chemical anchors connect the panels to the purlins and the purlins to the wall.
A1-grade non-combustible fireproof sealant and fireproof rock wool fill gaps to prevent flames and effectively enhance sealing performance.
Fiber cement anti-explosion partition board must be installed according to standard procedures, strictly following all procedures from base preparation, purlin fixing, panel installation, sealing, and reinforcement.
During use, product functionality may vary depending on the application environment. Furthermore, the installation location can affect the specific process. For example, there are significant differences between wall-mounted and ceiling-mounted fiber cement anti-explosion partition board.
Ensure the panels are vertically loaded to prevent cracking due to gravity. Galvanized steel joists should be installed at the bottom of the panels to prevent them from sinking. Reinforced keels should be installed in the middle of the wall, spaced <=1500mm apart, to prevent the panels from swaying under wind.
When installing suspended ceilings, be mindful of the risk of panels falling and injuring personnel or equipment below. Therefore, the weight of the panels should be controlled. Grid-shaped explosion-proof keels can be used as keels, and breakable hangers should be used to connect the keels to the roof.
fiber cement anti-explosion partition board undergo explosion-resistant testing, such as impact testing, after installation to ensure they can withstand the design pressure. If used in humid environments, select connectors with a zinc coating thickness of 80μm or greater to extend their service life.
Maintenance and care for fiber cement anti-explosion partition board primarily ensure their long-term, stable explosion-proof performance, preventing functional failure due to wear and tear, environmental degradation, or human damage. The following points should be noted during maintenance and servicing:
Check weekly for cracks, chipped corners, peeling, bulges, rust, scratches, cracked or detached fireproof sealant, loose self-tapping screws, exposed chemical anchors, and other issues. Repair any problems immediately.
Perform maintenance and servicing every 3-6 months to ensure proper function and check for stubborn stains. Check for deterioration in plastic clips and low-strength screws, and tap to check for hollowing sounds.
Although fiber cement anti-explosion partition board have a long service life, any problems discovered during maintenance and servicing should be promptly replaced.
