摘要： 抗溶水成膜泡沫灭火剂应用范围广泛，是处置各类极性和非极性液体火灾的重要技术手段之一。但因其含有黄原胶等组分，导致泡沫液黏度较大，存在一定的局限性。因此本文研发了低黏度抗溶水成膜泡沫灭火剂的基础配方，并研究泡沫的铺展性能，为后续低黏度抗溶泡沫灭火剂产品的研发提供理论指导。研究表明，本文研发的基础配方产生的泡沫在极性液体表面的铺展性能优于传统抗溶泡沫，并且低黏度抗溶泡沫中含氟聚合物的质量分数在6%~8%时，泡沫的铺展性能最佳；低黏度抗溶泡沫在非极性液体表面的铺展速度略快于传统抗溶泡沫，这主要与泡沫的析液时间有关。

Abstract: Alcohol-resistant aqueous film forming foam extinguishing agent is widely used and is one of the important technical means to deal with all kinds of polar and non-polar liquid fires. However, because it contains xanthan gum and other components, the viscosity of the foam concentrates is relatively large, and there are certain limitations. Therefore, the basic formula of low-viscosity alcohol resistant aqueous film forming foam extinguishing agent was formulated in this paper, and the spreading performance of the foam was studied, which provided theoretical guidance for the subsequent research and development of low-viscosity alcohol-resistant aqueous film forming foam extinguishing agent products. The results show that the foam produced by the basic formula developed in this paper has better spreading performance on the surface of polar liquid than the traditional alcohol-resistant foam, and the foam spreading performance is the best when the mass fraction of fluoropolymer in the low-viscosity alcohol-resistant foam is 6%~8%. The spreading speed of low-viscosity alcohol-resistant foam on the surface of non-polar liquid is slightly faster than that of traditional alcohol-resistant foam, which is mainly related to the foam drainage time.
