摘要

使用锥形量热仪测定了一种最常用的消防防护装备(也称为道岔装备)在热和烟雾危害方面的防火性能,使用热重分析仪测定了热稳定性,使用扫描电子显微镜对其表面进行了物理检查(物理降解),使用能量色散光谱仪测定了用于洗涤的洗涤剂的元素组成以及道岔装备中的残留元素。锥形量热仪的结果表明,热性能参数,即峰值放热率、最大平均放热率和火焰增长率指数的值均随洗涤次数的增加而降低,而烟雾参数,即峰值产烟率、烟雾增长率指数、总烟雾释放量和相关的持续火焰值均随洗涤次数的增加而升高。热重分析仪的测量结果表明,道岔齿轮的热稳定性随着洗涤次数的增加而降低。

The effect of repeated washings on thermal protective performances of one most used structural firefighting turnout gear in the Gauteng Province in South Africa
Fire performance measurements of one of the most used firefighting protective ensembles (also called turnout gears), in terms of thermal and smoke hazards, were determined with the cone calorimeter, that of thermal stability were determined with thermogravimetric analyzer, the physical inspection (physical degradation) of the surface done with the scanning electron microscopy, and energy dispersive spectroscopy measurements determined the elemental compositions of the detergent used in washing and the residual elements in the turnout gears. The cone calorimeter results indicated that the values of the thermal performance parameters, namely: peak heat release rate, maximum average rate of heat emission, and fire growth rate index, all decrease with increasing number of washing cycles, while the smoke parameters: peak smoke production rate, smoke growth rate index, total smoke release, and related sustained flaming values, all increase with increasing number of washing cycles. From the thermogravimetric analyzer measurements, the thermal stability of the turnout gears decrease with increasing number of washings.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
