Curing kinetics model
WebJan 18, 2024 · The isothermal kinetics of curing was described by means of model fitting and the isoconversional approach (Friedman method). Accurate n-order approximation was obtained for all systems under study. In particular, the 2-order equation fits well with the main part of curing excluding high degrees of conversion. WebAdd new model: In "Analysis" tree under "Model Based" click on "Add New". A new "Model Based" kinetic model will be created with default parameters: One step: A->B . Reaction type: F1, 1st order reaction. 6. Change reaction type for A-B kinetic step. It is known that curing reactions are usually autocatalytical reactions.
