This study was investigated to test the combustion properties of wood specimen for the constructional interiors, especially focusing on smoke performance index which is smoke hazard properties. Smoke release properties were measured by using a cone calorimeter (ISO 5660-1) and used cypress wood. The external heat flux was maintained at 50 kW/m2. The concentration of Talc was changed to obtain a blending ratio of proper concentration. Total smoke production by concentration was the lowest, with talc 20 being 4.93. Smoke performance index increased by 9.7 ~ 25.8% compared to uncoated specimens, respectively. The smoke growth index decreased by 87 ~ 92%. Smoke intensity decreased by 76 ~ 83%. According to the change of concentration, the smoke hazard properties were reduced in all specimens and the talc mixed with silicon sol improved the fire risk. |
