摘要
固体微粒气溶胶灭火剂是一种新型灭火材料 ,具有良好的抑制火灾的能力。研究了气溶胶灭火剂的固体产物对四种金属材料的腐蚀情况 ,对其腐蚀性做了定性及定量分析 ,评价了不同灭火剂的固体产物对四种金属材料的腐蚀性级别。结果表明 ,在相对湿度小于 5 5 %时 ,气溶胶灭火剂的固体产物在短时间 (≤ 8h)内 ,其腐蚀性非常小 ;随着时间的延长、湿度的增加 。
Pyrotechnically generated aerosol (PGA) fire extinguishing agent is a kind of new fire extinguishing material with excellent fire suppressing performance. Corrosion of the products of PGA fire extinguishing agent to four kinds of metal materials was studied. Qualitative and quantitative results were analyzed, and the corresponding corrosive levels were evaluated. Experimental results show that the corrosion to the metals is very small in the short time (≤8h) when relative humidity is less than 55%, and it gets worse with time and increase of relative humidity.
