Abstrakt: Nitrocellulose is a highly combustible substance that is extensively utilized in creating a variety of products, making the appropriate handling and storage of this material vital for worker safety. In our analysis, we assessed the dangers associated with nitrocellulose by both numerical and experimental research. We calculated the heat release rate, the time necessary to attain the maximum rate, and the total heat of reaction for nitrocellulose under various conditions using calorimetry and thermokinetic techniques. Our findings demonstrated that the rate of heat release and the total heat of the reaction rose as temperature and concentration increased. In addition, the addition of stabilizers and diluents to the nitrocellulose mixture reduced both the rate of heat release and the total heat of the reaction. The congruence between experimental findings and numerical simulations confirmed the validity of our modeling strategy. Overall, the results of our research give essential information for evaluating the dangers, such as the temperature and activation energy, associated with nitrocellulose and indicate viable solutions for strengthening the material's safety during handling and long-term storage.
