Study of Reactivity Photoacoustic Spectra of C/KNO3 Pyrotechnic by a Pulsed Nd:YAG Laser
Photoacoustic spectroscopy is a new type of material detection technology, because of its high sensitivity, good resolution, minimal sample size required and the detection is non-contact, etc.. It is paid more and more attention in the study of energetic materials. In this paper, indirect reactivity photoacoustic spectrum of C/KNO3 under laser irradiation was studied. When the laser energy increased, the photoacoustic signals recorded also increased. The imaging spectrometer detected the atomic emission spectroscopy signals of C/KNO3 which was irradiated by laser. From the perspective of the dynamic testing, the chemical reaction process was analysed. The TG-DSC curves showed the chemical reaction degrees of C/KNO3 under the Pharmacy and laser irradiation were different.
