Kovalenko I. Physical-chemical bases and technology of nitrate energy condensed systems

The thesis is devoted to the development of scientific bases and technologies of nitrate energy condensed systems as a safe alternative to industrial TNT-containing materials. The concept of mechanisms and features of NH4NO3 thermal decomposition kinetics as the main component of energy condensed systems and their interaction with mineral pyrite is advanced. The technologies of granulated ammonium nitrate modification are developed to obtain granules of high porosity (6.0-7.5% for liquid fuels) and optimal strength (7.0-9.0 N/grain). Modeling by mathematical neural network method is carried out. On the basis of the mathematical model of detonation and experimental research, the composition and conditions for obtaining bulk and patronized emulsion nitrate systems with water content of 8-17 wt % were determined. Physical and chemical bases of peroxide sensabilization of nitrate emulsions are developed. The compositions and technologies of granular, bulk and patronized emulsion energy condensed systems and their components are developed and implemented, which allowed solving the national scientific and technical problem of complex transfer of underground mines and quarries of Ukraine to the use of non-TNT explosive materials with the maximum safety of application.
