    摘要:

    研究了微粉石墨红外消光性能及其在燃烧型抗红外烟幕中的应用。结果表明: 微粉石墨在不产生凝聚的条件下,粒径越小,其红外消光效果越好。石墨作为成烟物质用于燃烧型抗红外烟幕时,存在燃烧损失,在相同烟幕剂配方中,石墨添加量从20%降至5%,用有机物B做可燃物时,石墨燃烧损失从31.6%增至57.6%; 用金属C做可燃物时,石墨燃烧损失从44.6%增至80.5%。为提高石墨利用率,在氧化剂A、有机可燃物B和20%微粉石墨组成的抗红外烟幕剂配方中,加入5%市售炭黑,同原配方相比,炭黑的加入能够有效抑制石墨燃烧和提高烟幕中石墨的红外消光能力。

    Abstract:

    Infrared extinction ability and application of tiny graphite powder in combustible antiinfrared smoke screen were studied. Results show that infrared extinction ability of dispersed graphite is stronger when its granularity is smaller. The graphite can burn when it is used in combustible antiinfrared smoke screen. When graphite is added from 20% to 5% respectively,its burning loss is accordingly increased from 31.6% to 57.6% in formula containing organic combustible and from 44.6% to 80.5% in formula containing metal combustible. In order to make use of graphite effectively,5% carbon black is added into combustible antiinfrared aerosol containing oxidant,organic combustible and 20% graphite. Compared to the original formula,the use of carbon black can effectively prevent combustion of graphite and improve infrared extinction of smoke screen containing graphite.
