一、防火涂料用于电缆阻燃的国内外现状 发电厂、变电所以及钢铁、化工等联合企业、高层建筑、地下铁道、船舶,都要涉及到很多的电缆。尤其是发电厂、变电所内,电缆群密集敷设,更是纵横交错,有若蛛网密布。这些电缆无论是它们本身散热恶化、绝缘下降击穿、弧光接地、中间接头盒爆炸等内因,还是电气设备火灾、油系统漏油、锅炉制粉系统防爆门爆炸及电焊渣掉落电缆上或沟道内等外因,都会导致电缆着火。电缆的外护层常用油纸绝缘、塑料绝缘、橡胶 First, the fire retardant coating for the current situation at home and abroad flame retardant power plants, substations and steel, chemicals and other joint ventures, high-rise buildings, underground railways, ships, should involve a lot of cables. In particular, power plants, substations, densely laid cable group, but also criss-cross, with cobwebs. Whether these cables are deteriorating due to their own heat, insulation breakdown breakdown, arc grounding, explosion in the middle connector box, or electrical equipment fire, oil system oil spills, explosive blast door explosion in the pulverizing system of the boiler and welding slag drop cable or ditch Road and other external factors, will lead to the cable on fire. Cable sheath commonly used oil paper insulation, plastic insulation, rubber
