摘要： 通过燃烧杯试验测得八氟环丁烷与N2、HFC-125、HFC-227ea混合物的火焰高度、火焰温度及火焰形态等数据，探究了八氟环丁烷与N2、HFC-125、HFC-227ea的协同作用及配比关系。结果发现，八氟环丁烷与N2和HFC-125表现出负协同作用，与HFC-227ea表现出正协同作用。当八氟环丁烷流量与HFC-227ea设置流量比为13:5时，表现出最佳正协同作用，灭火体积分数为7.02%，低于八氟环丁烷和HFC-227ea的最低灭火体积分数。

Abstract: Based on the flame height, flame temperature and flame morphology data of octafluorocyclobutane with N2, HFC-125 and HFC-227ea mixtures obtained from the combustion cup experiment, the synergistic effects and their proportional relationships were investigated. The results showed that octafluorocyclobutane showed negative synergy with N2 and HFC-125, and positive synergy with HFC-227ea. The best positive synergy was shown when the flow rate of octafluorocyclobutane was set at 13:5 with HFC-227ea, and the extinguishing volume fraaction was 7.02%, which was lower than the minimum extinguishing volume fraction of octafluorocyclobutane and HFC-227ea.

Key words: octafluorocyclobutane, synergistic fire extinguishing effect, composite fire extinguishing media, chemical fire extinguishing
