Efficiency evaluation of intumescent coatings used for fire protection: comparison between numerical method and experimental results
| Resumo: | An experimental study to assess the performance of water-based intumescent paints, used as a passive fire protection material, is presented. The specimens are steel plates coated with two different paints, three dry film thicknesses and tested with two different radiant heat fluxes in a cone calorimeter. The efficiency of this protection is attained regarding the substrate temperature evolution. A comparison between these experimental results and the ones obtained from a numerical model is presented. The numerical model considers the coating decomposition, and models the protection by two layers, the reacted and the unreacted layer (Mesquita et al, 2009). |
