摘要
新型的三相粘结性防灭火材料是利用黄泥的覆盖性、氮气的窒息性以及水的吸热降温特性来进行综合防灭火的。在对该防灭火材料的研究中,表面活性剂的选择是研究的重点与难点。通过对6种表面活性剂进行单一和组合发泡实验,研究各活性剂之间的相互促进和抑制关系。最终得出活性剂A1和A2质量浓度比为2∶1,质量浓度为0.006 g/mL时发泡最佳。
The new three- phase preventing and extinguishing material of caking property makes use of the cover ability of loess, asphyxiating of nitrogen and deealeseent characteristic of water to prevent fires. The study of the preventing and extin- guishing materials is focused on the choice of surfactants. Through single and combination foaming test of six kinds of surfae- tanta, the mutual promotion of relations and inhibitory relations between surfactants are researched. Finally it comes to a coneluaion that the best test is mass concentration of 0.006 g/mL and suffaetants of A1 ： A2 = 2：1.
