富碳有机物的成碳及红外干扰性能实验研究

Experimental Study on Carbon Particle Production and Its Infrared Interference Properties

采用烟火燃烧反应的方法将富碳化合物碳化得到碳黑。测试了碳黑的粒径分布、微观形貌及红外光谱透射率，并采用Mie散射理论计算了所制备碳黑的红外消光系数。结果表明，在4种不同结构的富碳化合物中，苯酐的成碳性能最好，形成的碳黑的粒径分布均匀，形貌一致，红外消光性能最佳。通过对实验中结果进行分析最终确定在新型抗红外干扰剂的配方设计中选用廉价且成碳性能优异的苯酐作为碳粒子产生剂。这为新型抗红外干扰剂的设计提供了重要理论依据。

Carbon particles are produced by burning different carbon-rich organics in pyrotechnic agent. The particle size distribution, microstructure and infrared （IR） transmission of these carbon particles are tested and IR extinction coefficient of the produced carbon particles is calculated using Mie scattering theory. The results show that the infrared extinction performance of the soot formed by phthalic anhydride is the best in the four tested compounds. The particle size distribution and microstructure of the soot are uniform. The study provides important theoretical basis for new anti-IR smoke agent design and recommends phthalic anhydride which has excellent performance and cheap price as carbon agent of new anti-IR smoke agent.
