Properties of Emulsion Matrices of Explosives Based on the Best Russian, Kazakh and Chinese Emulsifiers
Strain-stress properties of emulsion matrix (EM) poremit-type,obtained on the best emulsifiers of Russian,Kazakh and Chinese productions were investigated in this study.Comparative results are given here concerning emulsifying efficiency of the following emulsifiers: polymeric grade REM (Russia),pigmental grade P (Kazakhstan),polymeric grade SPAN-80 (China).The following parameters were estimated: microstructure,electric capacity,viability,thermal stability.Microstructure was determined by the method of optical microscopy with zooming in 400 times; viability was estimated according to electric capacity changing; thermal stability was measured by the method of differential thermo-gravimetric analysis;measurement of electric capacity was room-temperature.Studies concerning emulsifying efficiency showed that under equal experiment conditions more higher stress-strain properties and EM quality were obtained with REM.To achieve the same results of EM with SPAN and P,it is necessary to increase the content of emulsifier or burning phase in composition.
