劣质材料

2017-01-05

进入夏季,彩钢板集成房屋失火率比以往更高。经调查,绝大多数彩钢板房失火的主要原因在于彩钢板防火性能不达标。
  据了解,在2013年,我国实施了强制性的新国家标准《建筑材料及制品燃烧性能分级》(GB8624-2012),该标准明确了建筑材料及制品燃烧性能的基本分级为A、B1、B2、B3。通常情况下,彩钢板的燃烧性能必须达到A级,而很多彩钢房根本达不到这个标准。
  岩棉、玻璃丝棉等材料,防火性能可以达到A级,彩钢板夹层填充料如果使用上述材料,可起到阻燃作用。目前,市场上彩钢板芯材大多用聚苯乙烯泡沫作为填充料,而聚苯乙烯泡沫燃点低,不仅没有起到阻燃效果,还有助燃作用。
  在此,笔者呼吁,切勿搭建和使用劣质材料的集成房屋,一旦失火,后果不堪设想。
