采用Bruker OPAG33傅里叶变换红外遥测光谱仪,在自行研制的泡沫云起泡系统上,对泡沫云的中远红外波段信号的遮蔽性能进行了测试。结果表明:泡沫针对3～5μm和8～14μm的红外透过率随着起泡剂浓度的升高而先降低,当起泡剂浓度增加到0.1mol/L后,又开始升高;泡沫直径越小,中远红外透过率越低,泡沫云厚度越大,透过率越小。当直径分布为4～7mm时,厚度为10m时,3～5μm和8～14μm波段的红外透过率均在20%以下,且有效干扰时间在20分钟以上。研究结果可为这一新技术的战术运用设计,直接提供必要的理论基础和实验依据。
Using Bruker OPAG33 Fourier Transform Infrared Telemetry Spectrometer, the shielding performance of the far-infrared band signal of the foam cloud was tested on a self-developed foam cloud bubbling system. The results showed that the infrared transmittance of foam at 3 ~ 5μm and 8 ~ 14μm decreased first with the increase of foaming agent concentration. When the concentration of foaming agent increased to 0.1mol / L, The smaller the COSCO infrared transmittance, the greater the foam cloud thickness, the smaller the transmittance. When the diameter distribution is 4 ~ 7mm, the infrared transmittance of 3 ~ 5μm and 8 ~ 14μm band is less than 20% when the thickness is 10m, and the effective interference time is more than 20 minutes. The results of this research can be used to design tactics for this new technology and directly provide the necessary theoretical and experimental evidence.
