                【万鑫涂料科普】防火涂ㄨ料常识:防火涂料为什么能够防火

                防火涂料防火涂料百科全书为何可以防火为我们揭№秘。火灾的频频发作给很多人带来了难以弥补的损伤,为了减少发作火灾构成的丢失,就使得防火涂料防火涂料知识及介绍的开展适当→敏捷,那么防火涂料为何可以防火呢?无妨看看具体的介绍。

                防火涂料五大防火机理:

                (1)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触摸,推迟物体着火和添加】平息的速度。

                (2)防火涂料除本身具有难燃性或不燃性外,它还具有较低的导热系数,可以推迟火焰温度向被保护基材的传递。

                (3)防火涂料受热组成出不燃惰性气体,减弱被保护『物体受热组成出的可燃性气体,使之不易平息或平息速度减慢。   

                (4)含氮的防火涂料受热组成出NO、NH3等基团,与有机游离基化合,间断连锁反映,降高温度。

                (5)缩短型防火涂料受热缩短发泡,构成碳质泡沫隔热层封闭被保护的物体,推迟热量与基材的传递,阻挠物体着火平息或因温度下降而构成的强度下降
