简要介绍了哈龙灭火剂的灭火特性及其对臭氧层的破坏性, 重点评述了目前为保护大气臭氧层而研制或正在研制的各种哈龙替代灭火剂. 在此基础上, 对哈龙替代灭火剂的研究现状进行了分析, 并总结了目前哈龙替代灭火剂的发展趋势, 即所研制的灭火剂的性能应向清洁、无毒、 对环境无害、灭火性好, 投资少的方向发展.

Situation and Development Tendency of Replacement of Halon Extinguishing Agents

Characteristics of Halon fire extinguishing agents and their destroying mechanism to the atmospheric ozone layer were introduced.The research and development of various Halon replacements was reviewed and the properties of them such as HCFCs,HFCs,FICs,inactive gases,aerosol,fine water mist,new powder and foam extinguishing agents were emphatically discussed from several aspects such as efficiency,scope of application,environment effect and the development tendency.It showed that halohydrocarbons like HCFCs will phase out because of the potential threat to the environment,while fine water mist and aerosol will be better alternatives to Halons.The conclusion is drawn that the development tendency of Halon replacements is clean,hygienic to human being,harmless to atmosphere,high fire suppression effect and small investment.
