Пластмассы. Фенолоальдегидные смолы. Определение тепловых потоков и температурной реакции с помощью дифференциальной сканирующей калориметрии
Название (англ.):
Plastics; phenolic resins; determination of heats and temperatures of reaction by differential scanning calorimetry
Описание (англ.):
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.
