Abstract

In order to improve the radiation radiation area of Mg-PTFE infrared bait agent and reduce the radiation intensity, the Mg/PTFE/NC particle type agent was prepared by solvent evaporation method to study the infrared radiation performance of the particle agent. The results showed that the radiation area of the granular agent increased by 60% on average and the radiation intensity decreased by 84% compared with the equal-quality powdery agent. For granules, the radiation performance increases with the increase of particle size. When the particle size increases from 690.6μm to 1048.3μm,the average radiation area increases from 139.51cm2 to 172.83cm2,and the average radiation intensity is 2.89 W• Sr−1 increased to 4.56 W•Sr−1; while the mass fraction of Mg-PTFE in the granules also increased with the increase of mass fraction, and the effect on the radiation area was small; mass fraction When increasing from 30% to 70%,the radiation intensity increases from 2.64 W•Sr−1 to 5.62 W•Sr−1.
