摘要：

This work demonstrated the criterion of shear stability of emulsion explosive matrices (EEM), combined with rheology test, interfacial tension test, droplet size test and the crystallization test of emulsion explosive matrices. The shear stability of emulsion explosive matrices was defined as the characteristic refinement time of the droplet size decrease in emulsification process. The constitutive relationship between the characteristic refinement time and droplet size of inner phase droplets was proposed by theoretical analysis and experiments on the emulsification process of emulsion explosive matrices. By analyzing the relationship between rheological properties and characteristic refinement time of emulsion explosive matrices, the relationship model between Bingham coefficient and dimensionless coefficient was established to characterize the shear stability of emulsion explosive matrices. The effects of shear strength, shear time and shear shape on the stability of emulsion explosive matrices were studied. In addition, there exists a critical value to quantitatively characterize the shear stability of emulsion explosive matrices.
