Thermal Decomposition Properties of Epoxy Resin in Sulfr hexafluoride - MDPI

The results showed that thermal properties of 20% SF 6 /N 2 (volume fraction of SF 6 is 20%) mixture has faster degradation than 40% SF 6 /N 2 mixture. 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.Get price
