This firewall is widely used to block various penetrations, such as tunnels, cables, air ducts, oil pipes, gas pipes, and other openings formed when passing through walls (warehouses), building (A) slabs, as well as fire separation of cable trays, to prevent fire from spreading through these openings and gaps. It has excellent fire prevention function and is easy to replace.
Composition
Fire blocking materials include: fire blocking plate, foam blocking material, flame retardant module, fire sealant, flexible organic blocking material, inorganic blocking material and fire bag.
Function
The basic prototype of fireproof sealing is that the sealing material expands, absorbs heat, and provides insulation. When exposed to fire, it expands to seal the gaps left by the combustion of combustible materials, preventing the spread of toxic gases and smoke generated during fires; Heat absorption and insulation are used to reduce the temperature of the back and surface of the penetrating material, and to prevent the natural combustion of combustibles on the back surface.
