What are the characteristics of fire protection coating and fire protection board respectively?

At present, the tunnel fire protection is more than fire protection paint and fire insulation board, in the actual use of the process, what are their characteristics, is a simple introduction:
from the water content point of view, with glue as an interface agent fixed, applied to the pipe, without any gaps, the final water content than the pipe content is higher. And the fire plate in the construction process, with stainless steel nails fixed, and pipe between the air gap, the plate has a surface plastic seal, moisture is not easy to immerse in the plate, low water content.
most important thing is the fire protection of the product, which
the
. As far as fire protection coating is concerned, when under fire, the molecular structure contains high water content, produces hot gas wolf, bursts, the material density is lower and looser, the resistance to fire is obviously poor, because there is no support point and fall off. And magnesium oxide fire resistance is good, the board contains fiber by fire carbonization after the formation of a gap, the structure will not burst, combustion, plate and plate, plate and pipe between the gap, hot air from the gap, plus a number of layers of glass fiber cloth to do support, the board has a flat shoulder screw to do support, not easy to fall off. Therefore, fire protection coatings, service life is only five to ten years, the maintenance rate is higher, fire insulation board service life can reach 25 years, the maintenance rate is low.
Driving produces the influence of the top channel of the split pressure, the density of the coating is loose, there is negative pressure in the wind tunnel, the surface structure is attacked by wind pressure for a long time, the fire protection coating is destroyed over time, because the wind tunnel has a rough coating layer as the inner wall, the wind resistance coefficient increases. Fireproof insulation board density is high, strength is good, the surface is smooth, is the best material for style Road Oh.
to their respective construction environment requirements: paint construction, the relative humidity of the environment is less than 70%, the ambient humidity is greater than 5%, good ventilation, no such conditions construction quality will affect the cement solidification quality, the most common phenomenon is surface mold. Fire board construction on the temperature, humidity, ventilation without special requirements.
, compared with the tunnel fire insulation board on the tunnel fire protection paint cost-effective, more suitable for the needs of the market Oh.
