Study of the internal temperature of rigid polyurethane bodies using temperature sensors

This paper investigates the effect of filling polystyrene foam beads (EPS) on foaming temperature regulation rigid polyurethane (RPUF) composites and describes change process first 400 s reaction for two systems with high low RPUF. Different contents expandable EPS were used to regulate RPUF reduce internal structural defects composite material caused by excessive which is effectively optimized its use cost. HCFC-141B as physical blowing agent filler studied. MATLAB software was simulate pure both predict temperature. The comparison experimental data made, it concluded that too high. In addition, EPS-doped PUF porous in core region variation upper lower surfaces during measured using a probe sensor. represented three-dimensional trapezoid. maximum decreases more rapidly increasing content. heat loss smaller growth energy lead an increase mass fraction.
