【摘要】 在实验室条件下利用多波段红外辐射仪,对含不同聚合物的赤磷基发烟剂燃烧产生的烟雾对远红外辐射的透过率进行测试。试验表明:不同聚合物在发烟剂中所起作用不同,相似成分的发烟剂中加入氟可降低烟雾在远红外波段的透过率。并分析了上述烟雾在红外波段产生不同遮蔽效果的原因。更多还原

【Abstract】 Under laboratory conditions, transmittance of smokes produced by the burning of pyrotechnic compositions based on red phosphorus with different polymers is detected in farinfrared bands by IR spectroradiometer of muti-bands. Test result show that different polymer plays a different role in pyrotechnic composition; Adding fluorine into pyrotechnic composition with similar ingredient shall decrease the transmittance of smoke in farinfrared bands. The reason of different screening effect of smokes is also analysed in the infrared bands.更多还原
