自从进入21世纪后,能源的应用问题已经影响到我国经济的可持续发展。建筑能源的消耗成为我国主要能源消耗之一,因此研制节能型的建筑能源成为目前专家学者研究的重要课题。一些节能效果好的能源材料已经广泛的引用到外墙的保温中,但是这些材料遇火易融化,并且容易引发其它材料燃烧,同时在现行的防火设计中并没有细致的防火设计要求,所以一旦发生火灾危害相当严重。因此,本文就典型的外墙保温材料的PS火蔓延特性规律进行研究,希望对外墙保温的防火设计提供有效的指导与借鉴。
Since the 21st century, the application of energy has affected the sustainable development of our economy. Consumption of building energy has become one of the major energy consumption in our country. Therefore, the development of energy-saving building energy has become an important issue for experts and scholars at present. Some energy-saving energy-efficient materials have been widely used in thermal insulation of external walls. However, these materials will easily melt in the event of fire and easily lead to other materials burning. At the same time, there are no detailed fire-proof design requirements in the current fire protection design. The fire hazard is quite serious. Therefore, this paper studies the law of PS fire spread characteristics of typical exterior insulation materials, hoping to provide effective guidance and reference for the fire protection design of exterior insulation.
