열중량 분석법(TGA)을 이용하여 소방용 합성수지 배관으로 사용되는 CPVC의 활성화 에너지를 측정하였다. 열중량 분석법을 이용한 활성화 에너지는 Kissinger method와 Flynn-Wall-Ozawa method를 이용하여 계산하였다. 활성화 에너지를 계산한 결과 Kissinger method에 의해 128.07 kJ/mol, Flynn-Wall-Ozawa method에 의해 145.60 kJ/mol로 나타났다. Kissinger method와 Flynn-Wall-Ozawa method에 의해 계산된 활성화 에너지의 차이는 해석 방법이 다르다는 점을 감안했을 때 큰 차이가 없다고 판단된다. 향후 가속열화을 이용한 열적 열화평가 및 공기오븐노화시험을 통한 CPVC의 연소특성을 시험하고, 수명을 예측하고자 한다.
The activation energy of CPVC (Chlorinated Poly Vinyl Chloride) used for non-metallic synthetic resin piping in fire-fighting was measured by thermogravimetric analysis (TGA). The activation energy was determined using by TGA kinetic methods, such as Kissinger and Flynn-Wall-Ozawa method. The calculated activation energy was 128.07 kJ/mol (Kissinger method) and 145.60 kJ/mol (Flynn-Wall-Ozawa method). The difference in activation energies calculated by the Kissinger method and Flynn-Wall-Ozawa method was not considered to be significant considering that the different analysis methods. The combustion characteristics will be tested in a future study through an evaluation of thermal deterioration using an accelerated deterioration and air oven aging test and the lifetime of CPVC will be predicted.
Key Words: CPVC, TGA, Activation energy, Kissinger method, Flynn-Wall-Ozawa method
