摘要
在红磷发烟剂中分别加入四氧化三铁、三氧化二铁、氧化锰、硝酸铯、硝酸锶等氧化剂和可燃剂金属镁配制成六种发烟剂,在烟幕试验柜中测试了这六种不同配方烟幕的成烟时间、沉降速度和对10.6μm激光消光系数。研究表明,硝酸铯或硝酸锶作氧化剂时,烟幕的成烟时间分别为20 s和15 s,沉降速度分别为0.0021 m.s-1和0.0019 m.s-1,可以改善发烟剂的燃烧性能,而且烟幕对10.6μm激光的消光能力提高了41.9%和38.7%,因此,硝酸锶更适合作红磷烟幕的氧化剂。
Six kinds of RP smokes mixed with difference oxidants including F%O4 ,Fe2O3, MnO2 ,CsNO3, SrNO3 and combustible Mg were prepared seperatly, Their smoke shaping times, sedimentation rates and extinction coefficients to 10.6 μm laser were tested in a smoke chamber. Results show that the smoking time RP smoke with CsNO3 and SrNO3 are 20 s and 15 s, and the sedimentation rate are 0. 0021 m · s^-1 and 0. 0019 m · s^-1 , and the extinction coefficient to 10.6 μm laser increase 41.9% and 38.7% respectively. SrNO3 is better as oxidant for RP than CsNO3.
