以改进型HC发烟剂为基础配方,试验研究了发烟剂中赤磷的含量对所成烟幕的红外光谱透过率,初始浓度和沉降速度及烟幕粒谱分布的影响。试验结果表明,当烟剂中不含赤磷时,其烟幕在8－14μm波段的红外光谱平均透过率为22．4％,当发烟剂中赤磷含量为10％时,形成的烟幕在8－14μm波段的红外光谱平均透过率降至7．8％。
Based on modified HC, the influence of red phosphorus（RP）content on smoke spectrum transmissivity, initial concentration, settling velocity and particle size distribution is studied. Smoke chamber experiment results show that when RP content is 0% ,the average infrared spectrum transmissivity is 22.4% with smoke in 8~14 μm; when RP content is 10% ,the average infrared spectrum transmissivity is reduced to 7.8% in the same smoke region.
