Thermal Decomposition Properties of Epoxy Resin in Sulfr hexafluoride - MDPI

As ratio of SF 6 content decreases, thermal stability of the system decreases, and the decomposition process of SF 6 is exacerbated. Moreover, a mathematical model was established to determine happening of partial overheating faults on the epoxy resin surface in SF 6 /N 2 mixture. Also thermal decomposition process of epoxy resin was simulated by the ReaxFF force field to reveal basic chemical reactions in terms of bond-breaking order, which further verified that CO 2 and H 2 O producedGet price
