            虹牌涂料—防火涂料的原理

            [图文] 2015-05-26

             

            虹牌涂料讲防火涂料的防火原理大致可归纳为以下五点:
            ⑴、防火涂料本身具有难燃性或不燃性,使被保护基材不直接与空气接触,延迟物体着火?#22270;?#23569;燃烧的速度。
            ⑵、防火涂料除本身具有难燃性或不燃性外,它还具有?#31995;?#30340;导热系数,可以延迟火焰温度向被保护基材的传递。
            ⑶、防火涂料受热分解出不燃惰性气体,冲淡被保护物体受热分解出的可燃性气体,使之不易燃烧或燃烧速?#29123;?#24930;。
            ⑷、含氮的防火涂料受热分解出NO、NH3等基团,与有机游离基化合,中断连锁反应,降低温度。
            ⑸、膨胀型防火涂料受热膨胀发泡,形成碳质泡沫隔热层封闭被保护的物体,延迟热量与基材的传递,阻止物体着火燃烧或因温度升高而造成的强度下降。
