关于聚氨酯发泡塑料自燃性能的研究

主要研究测量通过回收处理还原的、用于一次性家用电器的、聚氨酯发泡塑料的最低燃点。随着样品容器量加大，聚氨酯的临界燃点降低，环戊烷-聚氨酯发泡塑料会发生剧烈燃烧。由于在环戊烷-聚氨酯发泡塑料的粉碎和储存过程中存在很高的火灾及粉尘爆燃危害，应该考虑对采用环戊烷-聚氨酯发泡塑料作为绝热材料的一次性家用电器的回收处理制定特殊的防火防爆规定。

A study on the autoignition characteristics of polyurethane foam

This study was performed by measuring the minimum ignition temperature of polyurethane foam recovered from the recycling process of the end-of-life home appliances.The critical ignition temperature of polyurethane foam was lower as the size of the sample vessel was increased, and that the combustion of cyclopentane-polyurethane foam occurred fiercely.It is considered that the recycling process of end-of-life home appliances using cyclopentane-polyurethane form as the insulator would require a special fire and dust explosion prevention measures since there exists a high potential hazard of fire and dust explosion during crushing and storage processes.
