Fireproof And Explosion-proof Composite Board

In high-risk industrial settings such as chemical plants, new energy storage facilities, pharmaceutical plants, and substations, ordinary wall panels struggle to meet both fireproof and explosion-proof requirements. Most conventional panels either only meet basic fireproofing needs and will crumble and collapse under blast impact, or they are heavy, cumbersome to install, and increase the overall load on the building. Therefore, fireproof and explosion-proof composite boards, commonly known in the industry as fiber cement composite steel plates, have gradually become the core material for the safety enclosure of high-risk buildings and are widely used in explosion-proof walls, partitions, and ceiling systems.

Typical Indicators for this Project

Combustion Performance: A1 grade, non-combustible (GB 8624)

Fire Resistance Limit: 1.5～4h (depending on thickness and wall structure)

Explosion Resistance: ≥1400kPa (approximately 1.4MPa), high-end models can reach 3000～4000kPa

Flexural Strength: ≥60MPa (core board)

Moisture Content: ≤10%

Environmentally Friendly: Asbestos-free, formaldehyde-free

Currently, mainstream Fireproof and explosion-proof composite boards adopt a "sandwich" composite structure, typically composed of the following parts

Core Material: Mostly high-strength fiber cement board or non-asbestos silicate fireproof board. The middle fiber cement layer plays a core role in absorbing energy upon impact.

Covering Material: High-strength perforated galvanized steel sheets (usually about 0.5mm thick) are covered on both sides, bonded together by mechanical pressure or extrusion. This galvanized steel surface material greatly increases the impact resistance of the board.

Thermal insulation filling (optional): When constructing thermally insulated explosion-proof walls, fire-resistant insulation materials such as rock wool are filled into the core of the frame to further enhance the fire resistance limit.

Fire-resistant and explosion-proof composite panels are widely used in industrial and civil buildings with potential explosion or fire hazards. Major applications include explosion-proof partitions, explosion-proof exterior walls, explosion-proof doors, explosion-proof ceilings, ventilation and smoke exhaust ducts, and cable channels.

Industrial applications: Petrochemical plants, pharmaceutical factories, gas/coal-fired boiler rooms, hazardous materials warehouses, waste recycling centers, offshore oil drilling platforms, etc.

Energy and transportation: Nuclear and oil-fired power plants, substations, subways, highway tunnels, airports and air stations, etc.

Other high-risk areas: Laboratories, data protection rooms, military manufacturing and storage equipment areas, etc.
