摘要:
采用白金环法测定了乳化炸药复合油相与硝酸铵水溶液的界面张力，并研究了乳化剂质量分数、温度、分子结构和热值对油水相界面张力的影响以及界面张力对乳胶基质微观结构和储存稳定性的影响。结果表明，随着乳化剂质量分数的升高，界面张力先下降后保持恒定;随着温度升高，界面张力呈线性下降趋势；复合蜡组分的异构化烷烃含量越高，环状化合物越少，热值越低，油水相界面张力越低。随着界面张力和临界质量分数的降低，乳胶基质的粒径减小。乳胶基质的储存稳定性随着油相材料界面张力的降低而增强。
Abstract:
Platinum loop method was applied to determine the interfacial tension between composite oil phase and ammonium nitrate aqueous solution in emulsion explosives. Influences of emulsifier mass fraction, temperature, molecular structure and calorific value on interfacial tension between oil and water were studied. Impacts of interfacial tension on microstructure and storage stability of emulsion matrix were also researched. The results show that the interfacial tension remains constant after falling with the increase of emulsifier mass fraction, and decreased linearly with the increase of temperature. Besides, interfacial tension between oil and water is lower when the isomerization alkane content of compound wax components is higher, cyclic compound is less and the calorific value is lower. Diameter of emulsion matrix decreases with the decrease of interfacial tension and mass fraction of critical micelle. Storage stability of emulsion matrix increases with the decrease of interfacial tension of oil phase.
