Study on the Heating Behavior of Fe3O4-Embedded Thermoplastic Polyurethane Adhesive Film via Induction heating

摘要

The heating behavior of thermoplastic polyurethane adhesive (TPU) embedded by nanometer or micrometer Fe3O4 particle is examined by induction heating. The effects of the size and the amount of Fe3O4 particle, TPU film thickness, and input power of the induction heater were examined on heating behaviors of TPU. The quantity of heat generated in the TPU films increased with the amount of Fe3O4 particles, film thickness, or input power. On the other hand, the quantity of heat generation of TPU is decreased with increasing Fe3O4 size. We confirmed that the mechanism of hysteresis led to heat loss in the nanometer and micrometer-sized Fe3O4 particles, and it was the key controller of the quantity of heat generated in the Fe3O4 particle-embedded TPU films by induction heating.
