How to use A/B explosion-proof mortar

A/B Type Explosion-Proof Mastic Usage Method of Construction Steps (1) Remove the oil and dust from the cables inside the packing box and the inner wall of the box plate.

(2) Use aluminum silicate hard bars (calcium silicate bar also) to separate the cables evenly.

(3) The range of the filler layer between the cable and the cable and the wall of the cable shall be 40---10 mma.

(4) The average thickness of packing filled in the stuffing box plug is greater than l00mm

(5) Pay attention to the use of a small piece of padding to seal the end face when caulking to prevent air bubbles. It is necessary to continuously compact the packing, seal the surface of the mouth, and then apply a seal auxiliary agent to make it smooth and seamless. (6) After the above steps, the cable stuffing box passed through the fire blocking cable should be coated with silicic acid on the cover. Aluminum fire insulation cover. Between the cable gaps of the insulating gas that are brighter than the sealing surface, the filling should also be full. At this time, it is also possible to use the DFD-11 type wire and cable fire blocking materials exported by the factory to borrow 4 pairs of sealing sealing pad boxes to be drilled due to poor seal quality or replacement of cables and other reasons. - 5mm hole (depth 40 ~ 50), and then after the filler with a tool to cut away from the sealed end to eliminate filler particles and powder, the new construction of the filler can still meet the sealing requirements.

5A, B filler no skin irritation, non-toxic, harmless to the human body, but the construction operation still need to wear a rubber sleeve, if there are fillers stuck to the skin, available alcohol, oil and other solvents, very easy to get clean.

Explosion-proof clay cement role:

Widely used in petroleum, chemical, gas stations, substations, dangerous warehouses and other areas of explosion hazards, as a display or cable wiring explosion-proof insulation seal. Can be used to package wires, connectors, cables, pipes, ground, etc., to prevent fire.

Popularly speaking, explosion-proof electrical industry in the explosion-proof electrical industry, our manufacturers mainly used in the explosion-proof distribution box and explosion-proof control box of the increased safety box and flameproof box sealing effect, while in the petrochemical industry in the wire and cable sealing performance Play a very important position, but also the vast majority used for sealing.
