DESIGN-EXPERIMENT INVESTIGATION OF MIXTURES ON BASE OF AMMONIUM NITRATE, CARBAMIDE AND BIURET

摘要

Porous charges on base of mixtures of ammonium nitrate, carbamide, biuret and aluminum were investigated in this work. Physical and chemical properties of biuret and carbamide were studied by means of differential scanning calorimetry method. Characteristics of fusion of mixtures ammonium nitrate/biuret were studied.At making of charges part of carbamide was replaced with biuret for improvement of detonation characteristics of early studied mixtures. Received mixtures were investigated by method DSC. It was established, what replacement of carbamide on biuret in mixtures of ammonium nitrate / carbamide / aluminum gives appreciable advantages. Such structures had good stability to moisture and heating to 100 °C without change of density and deformation. Detonation velocity studied mixtures were measured in the work Detonation velocity, oxygen balance were calculated for mixtures by means of SD code. Experimental data were compared with calculated values. Explanation of received results was given in the work
