Wire basket test is a hazard analysis method for the self-heating hazard of accumulated substances regulated in EN15188. However, this test requires a large amount of sample and long test period. To solve these issues, a new isothermal method to predict the self-heating temperature for any scale by obtaining pseudo activation energy of heat accumulation reaction using DSC has been developed. Governing equations at isothermal condition for nth-order reaction model and for autocatalytic reaction model were induced. From self-heating temperature at a scale obtained by wire basket tests and activation energy by DSC tests, the self-heating temperature can be easily predicted regardless of the accumulation scales.

使用等温DSC代替线篮测试的化学物质自热温度预测方法（EN15188）

钢丝篮测试是针对EN15188中规定的累积物质自热危害的危害分析方法。但该测试样本量大、测试周期长。为了解决这些问题，开发了一种新的等温方法，通过使用 DSC 获得蓄热反应的伪活化能来预测任何规模的自热温度。推导了n级反应模型和自催化反应模型的等温控制方程。根据通过线篮测试获得的一定规模的自热温度和通过DSC测试获得的活化能，无论累积规模如何，都可以容易地预测自热温度。
