CONTROLLED DATABASE ON THE BURNING TIME OF METAL PARTICLES IN THE DECOMPOSITION PRODUCTS OF FLUOROPLAST-BASED METALLIZED PYROTECHNIC MIXTURES

The article explores new patterns in the complex influence of various parameters on the burning time of magnesium,aluminum, and zirconium particles in the decomposition products of fluoroplastic-based metallized pyrotechnic mixtures. Experimentally-statistical models have been developed for predicting the influence of technological parameters on the burning time of metal particles, enabling the formation of a database of fire hazard properties under external thermal effects. Under forced external heating conditions, pyrotechnic mixtures may ignite, causing accelerated combustion and destruction of products, posing a fire hazard to surrounding objects. Systematizing the obtained data allows for more accurate prediction of the fire hazard properties of pyrotechnic mixtures and the development of effective risk reduction measures.To address the task, experimental-statistical modeling methods and specialized software were used to calculate the burning times of metal particles in the decomposition products of mixtures, enhancing the accuracy of predicting fire hazard properties under intense external heating conditions. Theobtained results provide practical use of models for assessing and reducing fire hazard risks. Additionally, these models will contribute to the development of new, safer pyrotechnic materials and products. This research is an important step in ensuring safety during the transportation, storage, and use of pyrotechnic products in various conditions.The obtained results ensure the practical application of models for evaluating and reducing fire hazard risks.
