摘要(Abstract)：

针对目前煤炭防灭火泡沫存在起泡性能低、稳泡时间短的问题,通过对现有表面活性剂进行复配,获得了泡沫性能良好的新型复合表面活性剂溶液体系。研究了复配体系的表面张力、泡沫性能,以及温度、无机盐离子对二元复配体系SDS/OP-10、SDS/OB-2、SDS/BS-12的起泡性能和稳泡性能的影响,并探讨了其性能变化的原因。结果表明:表面活性剂复配后均具有良好的协同增效作用,在其具有最低表面张力的复配比例下,起泡高度均超过100 mm,稳泡性能由高到低为阴/阳(SDS/OB-2)、阴/两性(SDS/BS-12)、阴/非(SDS/OP-10);泡沫性能最佳的复配体系为阴/阳(SDS/OB-2),在10-2mol/L NaCl存在时,起泡高度达133 mm,泡沫消失速度为0.01 mm/s。
