摘要:
为研究金属基电热膜的引燃能力,以棉被、毛巾为覆盖物,对不同电热膜通电功率、不同覆盖物厚度和含水率条件下,覆盖物不同位置处的温度变化情况进行了实验研究,并通过建立相应的模型,计算得到了不同环境温度下,覆盖物与电热膜接触处的温度。研究结果可以为电热膜火灾的预防,以及电热膜火灾的原因调查提供一定的参考。
关键词: 金属基电热膜, 引燃能力, 可燃覆盖物, 模型计算
Abstract:
In order to study the ignition ability of metal- based electrothermal film, cotton quilt and towel are selected as combustible cover materials. The temperature changes of various positions of the cover material were studied experimentally, under the conditions of different film power, covering thickness and moisture content. A model was established. The temperature of the place electrothermal film connecting the cover at different ambient temperatures were calculated by the model.The results of this paper can provide some reference data for fire prevention and fire investigation of electrothermal film fire.
Key words: metal- based electrothermal film, ignition ability, flammable cover, model calculation
