Thin fireproof coatings indoor fire principles can be summarized into the following five points:
⑴, fireproof thin coating itself incombustible or flame-retardant, so that the substrate to be protected from direct contact with air, and reducing the ignition delay combustion objects speed.
⑵, in addition to fire-resistant coating having itself flame retardant or incombustible, it also has low thermal conductivity, flame temperature is transmitted to the protective substrate may be delayed.
⑶, a thin non-combustible fire-resistant coating heat decomposition of an inert gas to dilute the protected object Thermal decomposition of the combustible gas that is less burning or combustion slows down.
⑷, fireproof coatings of heat decomposition of nitrogenous NO, NH3, etc. groups, with an organic radical compound, interrupting a chain reaction, lowering the temperature.
⑸, thin thermal expansion foam fire retardant coating steel, carbon foam heat insulating layer is formed closed object to be protected, delay heat transfer to the substrate, to prevent the object or the intensity ignition combustion caused by temperature rise decreases. Steel works are generally sprayed fire retardant coating to prevent avoid unnecessary losses.
