【摘要】 利用恒容静态平衡法,测定了包覆用氟橡胶-乙酸乙酯-CO2三元体系不同组成相应的临界温度和压力;以此为制备工艺参数确定的依据,将超临界流体反溶剂过程用于制备含3-硝基-1,2,4-三唑-5-酮(NTO)的高聚物粘结炸药,所得产品经组分分析、性能测试、吸光度的测量、红外光谱分析、扫描电镜(SEM)等手段,验证了该技术和工艺的可行性。更多还原

【Abstract】 The critical temperature and pressure of fluororubber-ethyl acetate-CO₂ ternary system are investigated by the static visual method at constant volume. On the basis of the results, NTO based polymer bonded explosive （PBX） is prepared by supercritical fluid anti-solvent method. The feasibility of the technique and the technology is validated by means of the sample component analysis,performance testing, absorbance testing, infrared spectra and SEM etc.更多还原
