近三十年来,人们从大火灾案例中日益认识到电线电缆阻燃和防火,对于抑制火灾扩散,控制火灾范围,减少人身伤亡和财产损失具有十分重要的意义。研究电缆的阻燃,提高它的使用安全性正在全球展开。本文想从世界和我国电缆火灾案例的分析着手,研究电缆燃烧成因和阻燃,对电线电缆阻燃技术和防火方面的有关问题作一些介绍和探讨。
In the recent three decades, people have come to realize the flame retardancy and fire prevention of wire and cable from the case of big fire. It is of great significance for suppressing the spread of fire, controlling the fire area, reducing the personal injury and property loss. Research on the flame retardant cable to improve its safety is being deployed worldwide. This article wants to start with the analysis of the world and China’s case of cable fire, to study the cause of the cable burning and its flame retardance, and to introduce and discuss some issues about the flame retardant technology of wire and cable and fire prevention.
