要約

The natural latex foam plays a significant role in our daily lives. Fire behavior of natural latex foam under bottom ventilation conditions is much different from the normal one, and the influences of bottom ventilation conditions on fire behaviors were rarely addressed in the literature. Therefore, fire behaviors of thermally thin natural latex foam under different bottom ventilation conditions (bottom holes dimension from 0 mm to 15.0 mm) were investigated experimentally. It was known from the experiments that the combustion characteristic time significantly decreases with bigger bottom holes up to 4.0 mm dimension and then it keeps the same even the size continues increasing. Flame showed a hollow structure under bottom ventilation. The flame spread rate of sample with 1.6 mm bottom holes was obviously lower than the others. A linear relationship was found between the flame spread rate and bottom hole dimension when it is larger than 2.3 mm. The flame spread for those samples with bottom holes dimension less than 1.6 mm almost happened at the sample surface, while for the others happened both at the surface and the bottom after bottom ignition. The preheat length showed an increasingly linear relationship with the dimension of bottom holes.
