Flexible Organic Plugging Material Heat Insulation Fire Resistant Plugging Fireproof Mud

  • Fire-resistant mud is a type of fireproof insulation plugging material, non-solidified type.
  • Can form an expanded carbon layer when exposed to fire. 
  • This kind of firestop putty mud finds extensive application in fireproofing cable trays, cable bundles, and small plastic pipes passing through floor or wall openings. 
  • For larger openings, fireproof mud also can be used in conjunction with other fire-blocking materials.

Description


Fireproof mud is a kind of fire insulation blocking material, which can form an expanded carbon layer in case of fire, and prevent the spread of flame and toxic smoke. In addition, it has the characteristics of high fire resistance, low smoke, water resistance, oil resistance, corrosion resistance, and long-term fire protection. Widely used in cable tray, cable bundles and small plastic pipe through the floor or wall openings of fire stuffing, larger openings, can be used with other fire blocking materials, as well as power plants, industrial and mining enterprises, high-rise buildings, shipbuilding power, post and telecommunications, substation, metallurgy and other system engineering in the vertical or horizontal wire.

How to use fire resistance mud plugging?


  • Before plugging the holes, clean them up, remove oil and dust, and sort out the cables.

  • Take out the product, knead it well into a dough, and cut it to a suitable shape. Perform fireproof sealing on the holes and gaps of the cable to be blocked. The plugging thickness should be consistent with the depth of the holes.

  • For large holes, first use steel structure brackets or fireproof partitions as the skeleton to increase strength, and use in combination with fire retardant bags or inorganic plugging materials.


Cautions



  • Before use, clean up the surrounding environment to remove objects such as oil and debris to prevent the adhesive strength of materials.

  • When it is used in large diameter construction environment, the structure should be built in advance to avoid the material falling due to large volume during filling, which will affect the service performance
