摘要:
为调控K树脂基可燃药筒的燃烧性能,降低其燃速系数,在可燃药筒基础配方中添加聚甲基丙烯酸甲酯(PMMA)有机降速剂,通过抽滤模压工艺制备了2个125 mm口径可燃药筒。采用压汞仪、绝热量热仪、有机元素分析仪、万能试验机和密闭爆发器,分别对可燃药筒孔的结构特性、热力学性能、力学特性和燃烧性能进行分析。结果表明,PMMA树脂可提高可燃药筒的火药力和力学强度,降低可燃药筒常、高及低温下的燃速系数,延长燃烧结束点时间,减小静态燃烧残渣及碳化物的产生。同时还可提高可燃药筒的真密度,降低其孔容、总表面积和孔隙率,并有助于减小可燃药筒燃烧过程中的燃烧面积和燃气渗透速率,进而控制燃气释放规律。
Abstract:
In order to tailor the combustion performance of K-resin based combustible cartridge cases,two 125 mm-bored combustible cartridge cases with the added poly(methyl methacrylate)(PMMA)resin are prepared by the pulp molding method. The pore structure,the thermodynamic properties,the mechanical characteristic and the combustion performance are studied by the mercury porosimetry,the heat meter,the organic element analyzer,the mechanical tests and the closed-bomb tests respectively. Results show that the incorporation of PMMA in combustible cartridge cases can improve the mechanical strength,the true density and the force capacity and reduce the combustion velocity coefficient and the residue after combustion. Meanwhile,the pore volume,the total pore area and the porosity of the obtained cases are also reduced by adding the PMMA,and it is benefical for tailoring the combustible surface and the gas permeation rate of the combustible cartridge cases.
