为满足高原地区低压低氧环境对火灾防治的特殊需求,在拉萨进行模拟试验,研究由溴氟丙烯和13X沸石所组成的气-固复合粉体灭火剂对汽油火的灭火性能,并与平原地区的合肥的灭火效果进行对比。试验结果表明,在拉萨低压低氧的环境下,复合粉体灭火剂对汽油火具有很好的灭火性能。在同样的试验条件下,其灭火时间和灭火剂用量比合肥减少20%以上,说明该复合粉体灭火剂在高原地区有很好的适用性。
To meet the demands of fire suppression in high plateau of Tibet with low pressure and low concentration of oxygen,performance of bromofluoropropene/zeolite 13X composite in extinguishing gasoline pool fires was studied in Lhasa.A comparison of the results with those from contrast experiments conducted in the plain area of Hefei was made.It was shown that as-prepared gas-solid composite particles could quickly extinguish the gasoline pool fires.Under the similar conditions,the fire extinguishment time and quantity of powder agents consumed in Lhasa were about 20% less than those of Hefei.The work validated that the gas-solid composite particles are adaptive for fire suppression in high plateau areas.
