摘要:
为有效防治油液在储运过程中易发生火灾问题，针对油液储运火灾特点，研发1种PFC-APG-SA水成膜泡沫材料。基于发泡性能、表面张力、pH值和抗烧性能，对复配的8种水成膜泡沫液开展性能测试实验，优选出最佳配方。结合分子动力学模拟，探究复配表面活性剂在模拟体系界面中分子排布作用的微观机理。研究结果表明：新型水成膜泡沫液发泡倍数为9.5，泡沫形态稳固，表面张力为17.521 mN/m，抗烧时间约为784 s，用量小且可以有效抑制油液燃烧；在分子动力学模拟中，复配的表面活性剂分子在油表面排列更为紧密，与油之间的相互作用能绝对值为8 210.238 kJ/mol，相互作用强且结构稳定。研究结果可为水成膜泡沫在油液储运火灾防治中的应用提供一定参考。
Abstract:
Aiming at the fire characteristics of oil storage and transportation,a PFC-APG-SA aqueous film-forming foam (AFFF) was developed.Based on the foaming property,surface tension,pH value and fire resistance,the performance test experiments of eight AFFF liquids compounded with surfactants were tested,to optimize the best formula.Combined with the molecular dynamics simulation,the micro-mechanism of molecular arrangement ofcompounded surfactants at the interface of simulation systemwas explored.The results showed that the foaming multiple of the new AFFF was 9.5,and the foam shape was stable.The surface tension was 17.521 mN/m,and the fire resistance time was 784 s,the dosage was small and the oil combustion could be effectively inhibited.In the molecular dynamics simulation,the compounded surfactant molecules were more closely arranged on the oil surface,and the absolute value of the interaction energy with the oil was 8 210.238 kJ/mol,with strong interaction and stable structure.The results provide certain reference for the application of water-forming foam in the prevention and control of oil storage and transportation fire.
