Abstract
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.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
