Construction site thick coating type Fire retardant coating Supply, steel structure Class I fire-resistant coating Supplied by the manufacturer
The thick coating fire retardant coating for construction site is supplied to the manufacturer, and the steel structure first class fire retardant coating manufacturers of the national standard GB14907-2002 are sold in batches. The thick coating fire retardant coating of our company is the steel structure fire retardant product of the national standard fire protection record, and the data is complete, which guarantees the acceptance quality of the steel structure fire retardant coating product. The thick coating fire retardant coating for construction is the national standard fire retardant 3h fire retardant coating, It is applicable to the construction of steel structure workshops, warehouses, buildings and other buildings with Class I fire resistance rating, as well as the fire protection of indoor and outdoor steel structures of steel structures.
The fire prevention principle of fire retardant coating can be summarized as follows:
1. The fire retardant coating itself is flame retardant or incombustible, so that the protected substrate does not directly contact with the air, delaying the ignition of objects and reducing the burning speed.
2. In addition to being flame-retardant or incombustible, the fireproof coating also has a low thermal conductivity, which can delay the transfer of flame temperature to the protected substrate.
3. The fireproof coating decomposes into incombustible inert gas when heated, diluting the combustible gas decomposed by the protected object, making it difficult to burn or slow down the burning speed.
4. Nitrogen containing fireproof coating decomposes into NO, NH3 and other groups when heated, combines with free radicals in agricultural production system, interrupts chain reaction and reduces temperature.
5. When heated, the intumescent fire retardant coating expands and foams to form a carbon foam insulation layer to seal the protected object, delay the transfer of heat and the substrate, and prevent the object from burning or strength reduction due to temperature rise.
