摘要: 为了防范矿用胶带和电缆燃烧火灾,文章采用FTT锥形量热仪测试并研究了其燃烧特性,并使用火灾危险性指标进行分析。试验测试胶带、电缆外护套和电缆绝缘层在30、40、50 kW/m2热辐射强度下的燃烧特性,建立了热释放速率经验预测模型。结果表明:热释放速率曲线在上升阶段和下降阶段分别呈现出幂函数和指数函数规律;热辐射强度的增大使材料热分解加快,燃烧反应历程缩短,点燃时间缩短,耐热能力变弱,火灾危险性增大。

Abstract: In order to prevent fires caused by the burning of mining belts and cables, the article used FTT cone calorimeter to test and study their combustion characteristics and analyzed their fire hazard indicators. The combustion characteristics of the belt, cable sheath and cable insulation under 30, 40 and 50 kW/m2 thermal radiation intensity were tested, and an empirical prediction model of heat release rate was established to study the heat release law. The results indicate that the heat release rate curve exhibits power function and exponential function patterns in the rising and falling stages, respectively. The increase in thermal radiation intensity accelerates the thermal decomposition of materials, shortens the combustion reaction process, shortens the ignition time, weakens the fire resistance performance, and increases the fire hazard.
