style="text-indent:25px">防火涂料厚型鋼結(jié)構(gòu)：涂覆在鋼構(gòu)件上的厚型鋼結(jié)構(gòu)防火涂料的防火隔熱原理是防火涂料受火時涂層基本上不發(fā)生體積變化，但涂層熱導(dǎo)率很低，延滯了熱量傳向被?；牡乃俣?，防火涂料的涂層本身是不燃的，對鋼構(gòu)件起屏障和防止熱輻射作用，避免了火焰和高溫直接進攻鋼構(gòu)件.還有涂料中的有些組分遇火相互反應(yīng)而生成不燃氣體的過程是吸熱反應(yīng)，也消耗了大量的熱，有利于降低體系溫度，故防火效果較顯，對鋼材起到高效的防火隔熱保護.另外該類鋼結(jié)構(gòu)防火涂料受火時涂層不發(fā)生體積變化形成釉狀保護層，它能起隔絕氧氣的作用，使氧氣不能被保護的易燃基材接觸，從而避免或降低燃燒反應(yīng).但這類涂料所生成釉狀保護層導(dǎo)熱率往往較大，隔熱效果差.為了取得一定的防火隔熱效果，厚涂型防火涂料一般涂層較厚才能達到一定的防火隔熱性能要求。</p><p style="text-indent:25px">防火涂料種類：防火涂料種類很多，但是按照防火涂料的使用對象以及防火涂料的涂層厚度來看，一般分為飾面型涂料和鋼結(jié)構(gòu)防火涂料。飾面型防火涂料一般用作可燃基材的保護性材料，具有一定的裝飾性和防火性，又分為水性和溶劑型兩大類。而鋼結(jié)構(gòu)防火涂料主要是用作不燃燒體構(gòu)件的保護性材料，這類防火涂料的涂層比較厚，而且密度小、導(dǎo)熱系數(shù)低，所以具有優(yōu)良的隔熱性能，又分為有機防火涂料和無機防火涂料。合格膨脹型防火涂料在受到噴燈等強火灼燒時，會大量發(fā)泡膨脹，表面聚集凸起，數(shù)分鐘內(nèi)不會出現(xiàn)燒損現(xiàn)象，而假冒偽劣防火涂料則基本不發(fā)泡，會出現(xiàn)大量散落掉渣的情況，木質(zhì)基材也會很快發(fā)生燃燒破損的現(xiàn)象。防火涂料因為其質(zhì)地疏松而具有良好的隔熱性能，可延滯熱量傳向被保護基材的速度。</p><div
