Experiment Study on the Ignition Point of XPS Foam Plastics

Abstract

In this paper, experiments were performed for the study of combustion characteristics of extruded polystyrene foam (XPS). The ignition temperature of extruded polystyrene foam (XPS) was studied by two different means in the fire laboratory of China University of mining and technology. Ignition temperature of extruded polystyrene foam (XPS) was measured by DW-02 type ignition point detector produced in the instrument analysis factory of jiang ning in Nan Jing. Ignition temperature with different heating power was measured by the radiation ignition instrument of extruded polystyrene foam (XPS). Results show that the ignition point of extruded polystyrene foam (XPS) measured by DW-02 type ignition point detector produced in the instrument analysis factory of jiang ning in Nan Jing was approximately 355 °C. Ignition point of extruded polystyrene foam (XPS) insulation board with 2.2 cm thickness was located approximately at 365 °C ∼ 370 °C, what's more, Ignition time of extruded polystyrene insulation boar (XPS) was gradually shortened as heating power increased. In a word, extruded polystyrene insulation board was more likely ignited by open fire than thermal radiation. Conclusions have a guiding role in setting material pyrolysis parameters during the FDS simulation of extruded polystyrene board (XPS) and have an important reference value in the selection of suitable external insulation materials in the practical engineering.
