To illuminate the thermal transfer mechanism of devices adopting polytetrafluoroethylene(PTFE) as ablation materials,the thermal radiation properties of PTFE plasma are calculated and discussed based on local thermodynamic equilibrium(LTE) and optical thin assumptions.It is clarified that line radiation is the dominant mechanism of PTFE plasma.The emission coefficient shows an opposite trend for both wavelength regions divided by 550 nm at a temperature above15 000 K.The emission coefficient increases with increasing temperature and pressure.Furthermore,it has a good log linear relation with pressure.Equivalent emissivity varies complexly with temperature,and has a critical point between 20 000 K to 25 000 K.The equivalent cross points of the average ionic valence and radiation property are about 10 000 K and 15 000 K for fully single ionization. 展开更多
