Abstract

The thermal decomposition characteristics of the ZPP(Zirconium/Potassium perchlorate), widely used as a primary charge of initiators, were investigated by differential scanning calorimetry(DSC). The DSC results with different heating rates were elaborated with AKTS-Thermokinetics software for the determination of the kinetic parameters of the thermal decomposition of ZPP. There was good agreement between the experimental and the simulation curves, based on the determined kinetic parameters, which indicates the validity of the kinetic description of the thermal decomposition process of ZPP.

착화기의 1차 점화장약으로 널리 사용되어지고 있는 ZPP(Zirconium/Potassium perchlorate)의 열분해 특성을 differential scanning calorimetry(DSC)를 사용하여 평가하였다. ZPP의 열분해반응에 대한 속도론적 파라미터를 결정하기 위하여, 다른 가열 속도를 갖고 수행된 DSC 결과들을 AKTS사의 Thermokinetics software를 사용하여 분석하였다. 결정된 속도론적 파라미터를 사용하여 계산된 모사값들은 실험적 결과들과 잘 일치함으로써, ZPP의 열분해과정에 대한 속도론적 모사의 유효성을 검증할 수 있었다.
