采用接触角张力仪测定乳胶基质体系油-水两相的界面张力。实验研究了温度对碳质燃料、乳化剂的表面张力的影响,以及乳化剂对乳胶基质中油-水界面张力的影响,结果表明,随着温度升高,碳质燃料、乳化剂的表面张力降低;而随着乳化剂质量分数的增加,油-水界面张力首先显著下降,随后趋向恒定值;乳胶基质体系中加入不同的乳化剂,高分子乳化剂形成的体系界面张力值相对较高。

Using contact angle tensiometer, measured the interfacial tension of oil-water two phase. The influence of temperature on surface tension of carbon fuel and emulsifier is investigated. Additionally, the effect of emulsifier on oil-water interfacial tension of emulsion base had been measured. The result indicate that, the surface tension of carbon fuel and emulsifier decrease as the temperature increases, interfacial tension of oil-water decrease significantly first as the emulsifier mass fraction increases, than the interfacial tension of oil-water be a constant value. Add different type emulsifier in emulsion base system, which use polymer emulsifier had relatively high value of interfacial tension. Results and findings have certain guiding significance, which for the formulation design and the safety production of emulsion explosives.
