摘要

为研究点火位置对乳胶泡沫材料水平方向火蔓延规律的影响。搭建小尺寸实验平台，在距离材料中心点0（x1）、3.54 cm（x2）、7.08 cm（x3）、10.62 cm（x4）、14.16 cm（x5）、17.70 cm（x6）位置处点火，研究了试样表面温度、质量损失、火焰高度、火蔓延速度等特性参数的变化规律。结果表明，随着点火位置由材料中心点向边缘点移动，平均火蔓延速度分别为0.24、0.23、0.19、0.31、0.42、0.51 cm·s

烧时间较长，平均质量损失速率较低，主要与火蔓延过程中的热量传递方式有关。研究结果显示了乳胶泡沫的火蔓延过程，得到了点火位置对火蔓延的影响规律。

Abstract

A small-size experimental platform was developed to study the effect of ignition position on horizontal flame spread of 2 cm thickness latex foam. The ignition position was 0 (x1)

3.54 cm (x2)

7.08 cm (x3)

10.62 cm (x4)

14.16 cm (x5) and 17.70 cm (x6) from the center point of the material surface. The characteristic parameters

such as surface temperature

mass loss

flame height and flame spread speed were measured during the tests. The results showed that the average flame spread rate is 0.24

0.23

0.19

0.31

0.42 and 0.51 cm·s

-1

for the tests that the ignition position is far from the center point of the material. At the x3 ignition position condition

the average flame height and mass loss rate was lower and the combustion time was longer than the other tests due to the difference of the heat transfer mode. Then the heat transfer mechanism of the combustion process with different ignition position was analyzed.
