摘要: 基于燃烧杯实验获得的火焰高度、火焰温度及火焰形态等参数,探究了反式-1,1,1,4,4,4-六氟-2-丁烯(HFO-1336 mzz(E),以下简称1336)与N2、六氟丙烷的协同灭火作用。在1336/N2的灭火过程中,1336体积分数小于15%时为正协同作用,最佳配比为5%∶95%。1336/六氟丙烷所有比例均为正协同作用,最佳配比为87%∶13%。六氟丙烷在一定程度上会增加火焰高度,并提高火焰温度,这是因为六氟丙烷的化学反应提供了额外的热量。

Abstract: Based on the parameters of flame height, flame temperature and flame shape obtained from the cup-burner experiments, the synergistic extinguishing effect of trans-1,1,1,4,4-hexafluoro-2-butene (HFO-1336-mzz(E),1336 in short) with N2 or HFC-236fa was investigated. The binary of 1336/N2 fire suppression agent showed positive synergism when the volume fraction of 1336 is less than 15%, and the optimum ratio is 5%/95%. All proportion of 1336/HFC-236fa exhibited positive synergistic extinguishing effect, and the optimum proportion is 87%/13%. The addition of HFC-236fa increased the flame height and flame temperature to a certain extent. This is because the fuel-like property of HFC-236fa caused extra heat release in the system.
