上海“11·15”特大火灾将聚氨酯这种新型外墙保温材料推到了风口浪尖。公安部消防专家分析事故原因时指出,聚氨酯保温材料是导致这场火灾的五大因素之一。人们担心,这种建筑保温材料如果被广泛采用,一旦房屋着火,就可能重蹈覆辙。甚至有人呼吁,今后在建筑保温改造工程中完全禁用聚氨酯材料。与此同时,也有专家指出,聚氨酯节能保温效果显著,火灾是不合格聚氨酯引发的,不能因噎废食。那么,在我国正在大力推行的建筑节能改造工程中,聚氨酯该不该禁用呢?
Shanghai “11.15 ” big fire Polyurethane, a new type of exterior insulation materials pushed to the cusp. Ministry of Public Security fire experts analyzed the cause of the accident pointed out that the polyurethane insulation material is one of the five major factors that led to the fire. People worry that if this kind of building insulation material is widely used, once the houses are on fire, they may repeat the same mistakes. Some even called for the future in the building insulation renovation project to completely disable the polyurethane material. In the meantime, some experts also pointed out that the effect of energy-saving insulation of polyurethane is remarkable. The fire is caused by unqualified polyurethane and can not be discarded due to waste. So, in our country is vigorously promoting the building energy-saving renovation project, polyurethane should not be disabled?
