摘要
火灾调查过程中,火灾现场蔓延特征是认定起火点的主要依据。实验研究塑料垃圾桶火灾蔓延特性,分别以纸张、布料引燃塑料垃圾桶,测试纸张位于垃圾桶内部不同高度处的火焰发展情况,高度分别为1/3、2/3高度以及与垃圾桶齐平,主要分析火焰高度、熔融滴落时间、软化时间等,得到纸张高度位置越高,火焰高度越大,完全熔化时间越短。
In the process of fire investigation, the on-site fire spread characteristics is the main basis for the identification of fire points. Experimental study on the fire spread characteristics of plastic trash was made, trash was ignited by paper and cloth, the flame development was analyzed with different height of paper as 1/3, 2/3 inside of trash and the same height with trash, the main flame height, the melt dropping time and the softening time were obtained, The results showed that with the increasing of the height of the paper, the flame height got greater while the complete melting time got shorter.
