Fire is a very terrible disaster, serious can hurt people, therefore, fire retardant coating is a very effective fire prevention method, especially the paint brush on the surface of those flammable materials, can improve the fire resistance of the material, slow down the spread of flame speed, or in a certain period of time can stop burning, give us more time to do a good job to escape and wait for rescue work. That todayTaiyuan fire retardant coating manufacturersWhat is the principle of fire protection for everyone to share?

1. fire retardant coatings have a lower thermal conductivity, which can delay the transfer of flame temperature to the substrate being protected.

2. coatings are heated to decompose NO, NH3 and other groups, and combine with organic free radicals to interrupt the chain reaction and reduce the temperature.

The 3. coating is decomposed by heating to produce non-combustible inert gas, which can dilute the combustible gas decomposed by heating the protected object, so that it is not easy to burn or the burning speed is slowed down.

4. coatings are flame retardant or non-flammable, so that the protected substrate is not in direct contact with the air, delaying the ignition of the object and reducing the speed of combustion.

5. fire retardant coating thermal expansion and foaming, the formation of carbonaceous foam insulation layer is closed to protect the object, delay the transfer of heat and the substrate, to prevent the object from burning or due to temperature rise caused by the decline in strength.
