可膨胀石墨用作抗红外/毫米波双模发烟剂的研究

为了获取一种性能较佳的毫米波发烟剂材料,就JF-150可膨胀石墨对3mm和8mm波的衰减性能进行了实验研究,在此基础上,以JF-150可膨胀石墨作为重要组分设计了一种抗红外/毫米波发烟剂配方,采用红外热像仪及毫米波辐射计测试了该发烟剂形成的烟幕对3mm和8mm波的衰减特性。结果表明,可膨胀石墨对3mm和8mm波单程最大衰减分别为17.0dB、16.6dB,优于铝箔条衰减效果;60g可膨胀石墨发烟剂对3mm和8mm波单程最大衰减值均大于10dB,干扰时间约为20s。可膨胀石墨是一种用于制造抗红外/毫米波双模发烟剂的良好材料。

Study on anti-IR/Millimeter Wave Smoke Composition with Expansive Graphite

For obtaining a good millimeter wave smoke materials,the attenuation performance to 3 mm and 8 mm wave of JF-150 expansive graphite was studied. Furthermore,the anti-IR/millimeter wave smoke composition with JF-150 expansive graphite was designed . The attenuation performance of the smoke formed by mentioned composition was also studied by the IR thermal image set and millimeter wave radiometer. The results show that the unilateralism maximum attenuation to 3 mm and 8 mm wave of expansive graphite are 17.0 dB and 16.6 dB,respectively,and better than that of the aluminum foil; the unilateralism maximum attenuation to 3 mm and 8 mm wave of 60 g expansive graphite are higher than 10 dB,the interference time is about 20 s. The expansive graphite is a good material for producing the anti-IR/millimeter wave smoke composition.
