Device mode of cable tray
Fireproof plugging materials are used to plug various penetrations. To prevent the fire from spreading through these openings and gaps, it has the function of fire prevention and is easy to change. Including: organic fire blocking materials, inorganic fire blocking materials and fire prevention (resistance, fire resistance) bags. Such as cables, air ducts, oil pipes, natural gas pipes, safe and harmless wall (silo) walls, floor (A) plates, and the segmented fire separation of cable bridges. With fire retardant, the organic fire blocking material is made of organic synthetic resin as binder. The material is rolled from filler, etc., and has plasticity and flexibility. The plugging material has good plasticity, is durable and does not solidify, and can cut, knead and plug holes of various shapes. When a fire breaks out, it can effectively prevent the spread of fire and the transmission of smoke. This kind of plugging material is mainly used in pipes or wires
In the fireproof plugging project of cable through holes, in most cases, it is used together with inorganic fireproof plugging materials and fire retardant packages.
