Abstract
동적 모델 방법을 이용한 TGA 문석방법을 이용하여 PVC 열분해의 속도론적 연구를 수행하였다. PVC의 경우 두 단계에 걸쳐 열분해가 일어나며 각각에 대하여 속도상수 값이 계산 가능함을 확인할 수 있었으며 첫 번째 열분해 단게에 대하여 159.7kJ/mol을, 그리고 두 번째 단계에 대하여 189.6 kJ/mol의 겉보기 활성화 에너지의 값을 각각 얻을 수 있었다. 또한 본 연구에서 제안한 속도론적 해석 방법의 효용성을 확인하기 위하여 기존의 문헌에 발표된 여러가지의 방법들을 이용항 PVC의 열분해 속도론적 결과와 비교 검토하였다.
The kinetic analysis of the thermal degradation of poly(vinyl chloride)(PVC) has been studied by a conventional thermogravitric technique using dynamic model method. The thermal degradation was found to be a complex process composed of at least two steps for which kinetic values can be calculated. The kinetic analysis of PVC gave apparent activation energy of 159.7 kJ/mol for the first step with a value of 189.6 kJ/mol for the second step. To verify the effectiveness of the kinetic analysis method proposed in this work, the results based on dynamic model method were compared to those of analytical methods reported in the literature.
