The Effect Of Shear Strength On Viscosity-Temperature Characteristics And Rheology Behavior Of Emulsion Explosive Matrix

In this work, the effect of shear strength on viscosity-temperature characteristics and rheological behavior of emulsion explosive matrix was investigated. It was demonstrated that the viscosity-temperature relationship of emulsion explosive matrix was in accordance with the Arrhenius equation. The increase of temperature leads to the decrease of viscosity and the value of d eta/dT. Besides, the sensitivity of viscosity towards temperature increased under lower temperature condition. With the increased of shear strength, the value of d eta/dT decreased at the same temperature. In addition, the activation energy of emulsion explosive matrix varied with temperature, which decreased with the increase of shear strength. The temperature phase transition characteristics of the emulsion explosive matrix under dynamic oscillation mode were discussed. It was found that the crystallization temperature decreased with the increase of shear strength, which lead to the increase of peak storage modulus and peak composite viscosity.
