- Abstract:
- In order to investigate the effect of water mist containing different additives on the alcohol extinguishing fire,exting experiments were carried out on water mist with different urea concentrations,potassium salt and FC-4 additives.The average fire extinguishing time of water mist with different concentrations of urea was compared under the same conditions.Comparing with water mist,water mist containing 1％ urea extinguished the alcohol fire in the shortest time,the extinguishing time reduction rate reached 44.63％.Water mist with K2C2O4· H2O extinguishied alcohol and kerosene fire in the minimal average extinguishing time,the extinguishing time reduction rate of fire suppression were 31.35％,73％ respectively.Water mist with KHCO3 extinguishied alcohol and kerosene fire in the maximal average extinguishing time,and reduction rates were 6.75％,57.56％ respectively.Water mist containing potassium extinguishing kerosene fire effect was better than to alcohol fire by contrast.Of all the compound additives,Water mist containing 0.05％ FC-4,1％ urea and K2C2O4· H2O with 0.2 mol/L K + extinguished the alcohol fire in the shortest time.And the extinguishing time reduction rate of fire suppression was 87.90％,the effect of fire suppression was remarkable.Compared with the above analysis,water mist containing compound additives was the better in alcohol extinguishing fire effect,and can realize extinguishing fire effectively.
