摘要:
从流动性、黏弹性和触变性3方面研究了现场混装乳化炸药基质的流变性。从流动性曲线可知，在低速剪切区域，乳化基质呈现牛顿流体性质。剪切速率继续升高后，乳化基质呈现剪切变稀型非牛顿流体性质。触变性试验结果说明，乳化基质结构恢复能力和所受外力大小有关，外力越大，乳化基质的结构越难恢复。黏弹性曲线表明，应变升高后，乳化基质逐渐从弹性形变转变成黏性形变。此外，乳化基质流变性受分散相液滴尺寸的影响较大。液滴尺寸减小，黏度和储能模量升高，外力消除后，乳化基质的结构恢复能力提高。
Abstract:
Rheology of bulk emulsion explosive matrix was studied in the aspects of flowability, visco-elasticity and rheopexy. Flow curves illustrate that the matrix exhibits the feature of Newtonian fluid in the region of low shear rates, and shear-thinning non-Newtonian fluid at continuously increased shear rates. Results of rheopexy show that recovery ability of matrix structure is closely related to the external force. The greater the external force, the harder the recovery of its structure. Visco-elasticity curve shows the gradual transition from elastic deformation to viscous deformation in the matrix with the increased strain. Besides, rheology of matrix is greatly affected by the droplet size in dispersed phase. Viscosity and storage modulus will increase with the decrease of droplet size. Structure recovery ability of matrix will improve upon the elimination of external force.
