使用DSC/TG联用技术对6种不同配比的硼/氧化铜延期药进行了热分析研究,并使用多元非线性拟合技术对硼含量为17%的B/CuO的动力学过程进行了求算。研究表明:B/CuO的反应为固-固相反应,其中硼含量为5%、8%、11%和14%时B/CuO反应不完全,而17%和20%时B/CuO反应相对完全。使用无模式的Firedman法对硼含量为17%的B/CuO分解的活化能和指前因子进行求算,结果表明其动力学过程十分复杂,至少存在两个反应。
The thermal analysis of six different boron / copper oxide delaying agents was carried out using DSC / TG technique and the kinetics of B / CuO with 17% boron content was investigated by multivariate nonlinear fitting Calculate. The results show that the reaction of B / CuO is solid-solid reaction, in which the B / CuO reaction is incomplete when the boron content is 5%, 8%, 11% and 14%, while the B / CuO reaction is not complete at 17% and 20% complete. The mode-free Firedman method was used to calculate the activation energy and the pre-exponential factor of B / CuO with a boron content of 17%. The results show that the kinetic process is very complicated and there are at least two reactions.
