Abstract

A violet pyrotechnic formulation is proposed based on the colour-light mixing principle, which is KClO₃/SrCl₂·6H2O/2CuCO₃·Cu(OH)₂/Al/C₆H_9.6O_1.6. To optimize the formulations, determine the types and contents of different colour emitters using the REAL calculation program, calculate the colour coordinates, wavelengths, colour purity and plot the chromatic diagrams of different formulations through the MATLAB program, and then optimize the formulations. Calculations showed that the formulation had an optimum ratio of 60/14/6/12/8, an oxygen balance of - 0.067 g.g^-1, a colour coordinate of (0.2500, 0.1392), a virtual dominant wavelength of 404nm and a colour purity of 0.35. The experimental results are that the colour coordinates are (0.2541, 0.1706), the virtual dominant wavelength of violet light is 439nm, the colour purity is 0.34, and there is a good violet light effect. The theoretical simulation results are in good agreement with the experimental results, and the design method can provide a theoretical basis for the other multidye flamer chromatic pyrotechnic formulations and the study of related problems.
