Flexible organic fire blocking material

Fire blocking material (refractory mud): 40KG/bag, 20 sachets/bag

Suitable for power, telecommunications, postal, chemical, industrial and mining, enterprises, construction and underground engineering to block various penetrating objects, such as cables, air pipes, air pipes and metal pipes, etc., which are formed when they pass through barriers or barriers. The fireproof partition has a fireproof function. It is used in smaller cable penetration holes, gaps and other special-shaped holes that are not suitable for fire blocking materials and places where cables are replaced frequently.

Matching construction of organic and inorganic fireproofing materials --- For large-area cave projects that require frequent disassembly, this method can be used.For some small gaps, the use of organic blocking materials is easy to meet the construction purpose, but for large-area caves, because it is soft and cannot be shaped, it is difficult to meet the construction requirements, so the construction method of organic and inorganic blocking materials is used for the construction of large caves. .Inorganic plugging materials can also be used, and the fire retardant package can be used alone or in combination.

(1) Choose a plastic pipe larger than the section of the wire and cable longer than the sealing wall, cut it, and cover it on the wires and cables in the construction section, so that the plastic pipes on the wires and cables can move freely, and ideally, the wires and cables As the center, the wires and cables can be wrapped around a gap of one centimeter of organic plugging.

(2) After the above work is completed, nail the template according to the size of the cave to be constructed, and plug the adjusted inorganic plugging material.

(3) The use of inorganic blocking material and the calculation of the material used --- The blocking material should be plugged according to the size of the hole required during construction, and the amount of the blocking material will be estimated, and then the blocking material will be put into the container according to 1:0.6- Add water in the proportion of 0.7 and stir it into a paste for immediate use. If the amount is large, it is usually done in several times.The stirring volume is about 5 kg each time.When plugging larger holes, an appropriate amount of steel bars can be used to increase the expected strength, and the thickness of the plugging can be determined according to needs, generally not less than 15 cm.Fill the hole with a volume of 1m3.1.3 tons of this blocking material is required.

(4) When the inorganic plugging is completed for about 15 minutes, the plastic casing is removed, and the organic plugging can be filled in the gap.
