摘要
采用液-固水热反应,研究了半封闭的恒温条件下,利用多孔镍与硝酸铵、水合肼反应,在多孔镍表面生成一层致密的多孔硝酸肼镍。用光纤测时法测量了不同增重率的多孔硝酸肼镍的爆速,结果表明,最佳的增重率为35%-40%,此时爆速最大约为2300 m·s^-1。通过正交实验得到了多孔硝酸肼镍最佳生产条件:水合肼浓度0.256 mol·L^-1,硝酸铵浓度0.192 mol·L^-1,反应温度65℃,pH值9,并实验验证了该条件下生产的多孔硝酸肼镍爆速范围为2357-2499 m·s^-1。
The porous nickel hydrazine nitrate(NHN) was obtained by in-situ liquid-solid reaction of ammonium salt, hydrazine hydrate and porous nickel under constant temperature in half-closed environment. The detonation velocities of NHN with different mass increase rate were measured using optical fiber time measurement method. Results show detonation velocity is maximum (about 2300 m·s^-1 ) when the mass increase rate ranges from 35% to 40%. The optimum reaction condition to obtain NHN with high detonation velocity was investigated by orthogonal test. It is found when the concentration of hydrazine hydrate is 0. 256mol·L^-1 , and the concentration of ammonium nitrate O. 192 mol·L^-1, and reaction temperature 65 ℃ and pH 9, the detonation velocity of NHN reaches up to 2357-2499 m · s^-1
