Explained in detail below:
1. we know that the fire retardant coating itself is flame retardant or non-flammable, so the protected substrate will not be in direct contact with the air, delaying the ignition of the object and reducing the rate of combustion.
2. Fire retardant coatings decompose non-combustible inert gases when heated, dilute the combustible gases decomposed by the protected object, making it difficult to burn or slow down the combustion rate.
3. In addition to flame retardant or non-combustible properties, fireproof coatings also have a low thermal conductivity, which can delay the flame temperature to the protected substrate transfer.
4. Nitrogen-containing fireproofing coatings decompose into groups such as no and NH3 when heated and combine with organic radicals to interrupt the chain reaction and reduce the temperature.
The intumescent fireproof coating heats up and expands, forming a carbon foam insulation layer, sealing the protected object, delaying the transfer of heat and substrate, and preventing the fire from burning or the decrease in strength caused by the increase in temperature.
The role of applying fireproof coating is fire resistance. Does the use of fireproof coating help to improve the fire resistance of building components? With the development of fire retardant technology in China, advanced, high-quality fireproof coatings have emerged. From the point of view of active application, the effect is obvious.
