航空煤油的羟丙基纤维素凝胶力学性能研究

Mechanical Properties of the Aviation Kerosene Gels with Hydroxypropyl Cellulose as a Gelator

采用软固体测定仪,研究了胶凝剂、表面活性剂、稳定剂用量对航空煤油凝胶力学性能的影响。结果表明在实验条件下,随胶凝剂用量和表面活性剂OP10用量的增加,凝胶的屈服应力增加。引入稳定剂C可使凝胶形成时间显著缩短,抗剪切能力显著增强。

The mechanical properties of the aviation kerosene gels with hydroxypropyl cellulose as a gelator are studied by using a soft solid tester. It is found that the contents of the components excepting the solvent and the gelator,including surfactants ,stabilizers and other additives influence the yield stress of the gels significantly. The yield stress increases along with increasing the concentration of the gelator or that of the surfactant,OP 10. Introduction of the stabilizer C accelerates the formation of the gels and improves the performance of the gels subject to shear force.
