标准范围

规定方法的原理是测量供应给试样的热流，作为时间或温度的函数，同时试样在规定的大气条件下处于温度表中。反应的标志是样品释放能量，导致加热曲线出现放热峰。将记录的峰面积积分为时间的函数，可以测量反应的能量。适用于具有放热行为的酚醛树脂，如酚醛树脂与六亚甲基四胺或其他固化剂的酚醛树脂或混合物。

The principle of the method specified is measuring the heat flux supplied to a test sample as a function of time or temperature, while the test sample is subjected to a temperature schedule under a specified atmosphere. A reaction is marked by the release of energy from the sample, resulting in an exothermic peak in the heating curve. Integration of the recorded peak area as a function of time gives a measure of the energy of the reaction. Applies to phenolic resins with exothermic behaviour, such as resols or mixtures of novolaks with hexamethylenetetramine or other curing agents.
