摘要
基于典型场所的火灾载荷密度及可燃物,制备了典型的塑料杯组合体和纸杯组合体标准燃烧物,开展两种标准燃烧物的燃烧特性试验研究。结果表明,两种典型的标准燃烧物的燃烧性能稳定,总热值、火灾增长速率数据偏差较小,实验的重现性良好;在一定条件下,塑料杯组合体标准燃烧物可近似代表火灾载荷约为157.8 MJ的近中速火,纸杯组合体标准燃烧物可近似代表火灾载荷约为51.1MJ的慢速火。
Typical plastic-cup and paper-cup standard combustible material have been prepared based on fire load density and material composition of the typical places.Experimental research on these 2combustible materials' combustion characteristic shows that:their combustion properties are stable,total heat release and fire growth rate have small deviation,and the tests have good reproducibility.Under certain conditions,plastic-cup standard combustible material can represent quasi medium fire with fire load of 157.8 MJ,and paper-cup standard combustible material can represent slow fire with fire load of 51.1MJ.
