Background
In the field of construction, a firewall means an incombustible wall body that prevents a fire from spreading to an adjacent area and has a fire resistance limit of not less than three hours, and is an important partition member for dividing fire zones or preventing the spread of a fire between buildings. When a pipeline and a cable are arranged in the firewall in a penetrating mode, a fireproof blocking technology is generally adopted to prevent fire from spreading to the other side of the firewall. Fireproof sealing is used for sealing various penetrations, such as various openings formed when cables, air pipes, oil pipes, air pipes and the like pass through wall (warehouse) walls and floor (deck) plates and fireproof separation of cable bridges so as to prevent fire from spreading through the openings and gaps, and fireproof sealing materials comprise: fireproof plugging plates, foam plugging materials, flame-retardant modules, fireproof sealant, flexible organic plugging materials, inorganic plugging materials, fire retardant bags and the like. The fireproof plugging material is used for sealing the cable or the pipeline to penetrate through the wall body or the floor slab to form a hole, so that the fire can be prevented from spreading to an area adjacent to an ignition source, and the purpose of protecting the safety of personnel and equipment is achieved. The basic principle of the fireproof plugging is that the plugging material plays roles of expansion, heat absorption and heat insulation, expands when meeting fire to seal gaps left by combustible combustion, and prevents the spread of toxic gas and smoke generated in the fire and the fire; the heat absorption and the heat insulation are used for reducing the temperature of the back fire surface of the penetration object and preventing the combustible substance on the back fire surface from spontaneous combustion.
When doing the fire prevention shutoff to the civil air defense engineering, especially need notice cable duct's fire prevention shutoff, the cable sheath generally uses the polyethylene preparation, the burning takes place easily for the polyethylene, and black cigarette is strong, because the inside only has two exports from top to bottom of pipeline, black cigarette can only be followed these two exports and discharged, at this moment, fire prevention block structure only can play the mesh that makes the intensity of a fire can't stretch to next floor, can't in time be discover when leading to the cable to catch fire, contain a large amount of hydrocarbon in the black cigarette simultaneously, harmful to the human body, and the polluted environment.
