新型泡沫干扰剂的红外消光系数测试研究

Infrared Extinction Coefficient Testing of a Novel Foams Obscuring Agent

为评价泡沫干扰剂的红外消光性能,采用热像仪遥测光谱仪对泡沫的红外消光系数进行了测定,给出了热像仪和光谱仪测定泡沫红外消光系数的方法,并对比了两种方法的测定结果。结果显示,两种方法所测结果相近,能比较客观地反映泡沫的红外遮蔽干扰能力。研究认为,这两种方法均操作简单并具有较高的精度,可用于泡沫的消光系数测试,为保证测试结果的可靠性,这两种方法应配合使用。

To evaluate the infrared attenuation properties of a novel foams obscuring agent, a thermal imager and an FTIR spectrograph were applied to test the infrared extinction coefficient （ EC ） of a novel foams obscuring agent （FOA）. The methods of infrared thermography and spectrogrum are presented, and the results obtained based on them and the methods themselves are been compared. It indicates that two close EC results get truly by the two methods. So it figures out that the methods would be applied conveniently to test the EC of FOA with a high precision, and should be assisted and validated each other.
