硝化棉质量差异分析及其对推进剂制品性能的影响OA北大核心CSTPCD
Analysis of Quality Difference of Nitrocellulose and Its Influence on the Propellant Products Properties
为了获得D级硝化棉质量差异对其理化性能和推进剂制品性能的影响规律,对4种不同厂家、不同批次硝化棉样品的"八大度"、分子质量、分子质量分布及硝化均匀性等进行了表征及分析,并制备了 4种改性双基(CM-DB)推进剂样品,比较了各样品力学性能及燃烧性能的差异.结果表明,4种D级硝化棉样品的"八大度"均符合国军标要求,含氮量范围为11.9％～12.1％,GPC测得数均分子质量范围为0.59×105～0.73×105 g/mol;硝化棉含氮量小幅下降会使其…查看全部>>
To ascertain the effect of D-grade nitrocellulose's(NC)quality variation on its physicochemical properties as well as its propellant products,the"eight major properties",molecular mass,molecular mass distribution,and nitrification uni-formity of four types of NC samples of different manufacturers and batches were characterized.The CMDB propellant contai-ning four types of NC samples were also prepared,the mechanical and combustion properties were compared.Th…查看全部>>
