    摘要:

    为了比较不同蓝光烟火药的发光效果和探讨配方优化设计的新方法,利用REAL热力学计算程序对六种蓝光烟火药进行了热力学研究,建立了蓝光烟火药燃烧反应焓与火焰温度和辐射光子数之间的关系,根据计算得到的燃烧火焰温度和辐射蓝光的光子数,优选了蓝光烟火药配方及配比。结果表明, 六种不同蓝光烟火药的燃烧温度为1651~2880 K,这与利用NASA-CEA程序的计算结果一致,在最大波长处辐射的光子数为0.02011~0.0435 mol·kg-1,且产生蓝色火焰的主要辐射体为CuCl。借助蓝光烟火药的燃烧反应焓、火焰温度和辐射光子数之间的函数关系式,计算得出含KClO3、2CuCO3·Cu(OH)2和S的蓝光烟火药燃烧温度为1651 K,辐射光子数为0.0435 mol·kg-1,在六种配方中其蓝光辐射效果最好,该配方的最佳配比为KClO3/2CuCO3·Cu(OH)2/S=63/19/18, 为其它火焰烟火剂的设计和优化提供了一种新的方法.

    Abstract:

    To compare the luminescence effect of different blue light pyrotechnic compositions and explore the new method of optimal design of formulations, the thermodynamic study on six kinds of blue light pyrotechnic compositions was carried out by REAL thermodynamic program. The relationship among the enthalpy of combustion reaction, flame temperature and emitted photon numbers of blue light pyrotechnic compositions was established. The formulation and proportion of blue light pyrotechnic compositions was optimized and selected based on the combustion flame temperature and photon numbers of emitted blue light obtained by calculation. Results show that the combustion temperatures of six kinds of blue light pyrotechnic compositions are 1651-2880 K, which is in accordance with the results calculated by NASA-CEA program. The photon numbers emitted at the maximum wavelenght are 0.02011-0.0435 mol·kg-1 and the major emitter that produces blue flame is CuCl. With the help of the relationship among the enthalpy of combustion reaction, flame temperature and emitted photon numbers of blue light pyrotechnic compositions, the combustion temperature of the blue light pyrotechnic composites containing KClO3, 2CuCO3·Cu(OH)2 and S is 1651 K. The emitted photon number is 0.0435 mol·kg-1. The emitted effect of blue light is better in the six kinds of formulations. The optimal proportion of the formulation is KClO3/2CuCO3·Cu(OH)2/S=63/19/18. It provides a new method for the design and optimization of the other light pyrotechnic compositions.
