摘要
在分析可膨胀石墨膨胀机理基础上,实验研究了三维空间中的膨胀石墨对3mm、8mm波的衰减性能。结果显示,膨胀石墨能够较好地衰减3mm和8mm波辐射,其衰减性能随着可膨胀石墨粒度减小而降低。当可膨胀石墨作为毫米波干扰新型材料或发烟剂主体成分时,只有选用合适粒度才会获得较好的衰减效果。
On the basis of analyzing expanded mechanism of expansible graphite,attenuation performance of expanded graphite in three-dimensional space at 3 mm and 8 mm wave was studied by experiments. The results show that expanded graphite has a valuable attenuation performance at 3 mm and 8 mm wave,and its attenuation performance decreases with the reduction of expansible graphite particle size. It is essential to choose appropriate particle size to obtain a valuable attenuation performance when expansible graphite is used as a new millimeter wave interfering material or the main component of smoke composition.
