CALCULATION OF THE SPECIFIC HEAT OF EXPLOSION OF A LOW-DENSITY MIXTURE OF EMULSION EXPLOSIVES AND EXPANDED POLYSTYRENE GRANULES

Abstract

According to current terminology, emulsion explosives (EE) mixed with expanded polystyrene (EPS) granules are referred to as emulpors. The calculation of the specific heat of explosion for these explosives is complicated by the lack of reliable data on the chemical composition of the fuel phase used in EE manufacturing and the absence of reliable experimental data on the composition of explosion products. This article determines the contribution of the emulsifier's heat of formation to the specific heat of the EE explosion and provides calculated values for the heat of formation of hydrocarbon fuels used in EE production. Based on the research conducted, a methodology was developed to determine the specific heat of explosion for a low-density emulsion mixture, accounting for both its chemical composition and the volumetric content of EPS granules.
