摘要：

为研究洁净厂房内典型可燃物的火灾燃烧特性，通过对洁净厂房的实地调研，选取不同组合的聚丙烯塑料箱和聚苯乙烯塑料盒，分别采用3 MW 量热仪和10 MW 量热仪开展了4组全尺寸火灾燃烧特性试验。试验结果表明，无论是单组、双组还是4 组铺设，聚丙烯塑料箱均具有较高的火灾危险性，其燃烧增长速率和最大热释放速率在燃烧增长阶段的发展过程均接近超快速火，且几乎无平稳燃烧阶段。聚丙烯塑料箱平铺面积增大后，除热释放速率增大外，也进一步提高其火灾增长速率；聚苯乙烯塑料盒在燃烧增长阶段的发展过程为中速火，平稳燃烧时间较长。

Abstract:

In order to study the fire and combustion characteristics of typical combustibles in clean workshop, four groups of full- scale fire combustion characteristics tests were carried out by selecting different combinations of polypropylene plastic box and polystyrene plastic box by using 3 MW calorimeter and 10 MW calorimeter respectively. The test results show that the polypropylene plastic box has high fire risk whether it is arranged in single group, double group or four groups. The development process of its combustion growth rate and maximum heat release rate in the combustion growth stage is close to the ultra fast fire, and there is almost no steady combustion stage.In addition to the heat release rate, the fire growth rate will be further increased with the increase of tile area; the development process of polystyrene plastic box in the combustion growth stage is medium speed fire, and the stable combustion time is longer.

Key words: polypropylene, polystyrene, combustion characteristics;HRR, value of combustion
