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(shí)涂層基本上不發(fā)生體積變化，但涂層熱導(dǎo)率很低，延滯了熱量傳向被保基材的速度，防火涂料的涂層本身是不燃的，對(duì)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(jìn)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?xì)怏w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(duì)鋼材起到高效的防火隔熱保護(hù).另外該類鋼結(jié)構(gòu)防火涂料受火時(shí)涂層不發(fā)生體積變化形成釉狀保護(hù)層，它能起隔絕氧氣的作用，使氧氣不能被保護(hù)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(hù)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(dá)到一定的防火隔熱性能要求。廣州進(jìn)口防火涂料防火涂料對(duì)涂膜的防火性能及理化性能研究雖然進(jìn)展較快。</p><div

style="text-indent:25px">防火涂料防火原理：防火涂料的防火原理大致可歸納為以下幾點(diǎn)：⑴、防火涂料本身具有難燃性或不燃性，使被保護(hù)基材不直接與空氣接觸，延遲物體著火和減少燃燒的速度。⑵、防火涂料除本身具有難燃性或不燃性外，它還具有較低的導(dǎo)熱系數(shù)，可以延遲火焰溫度向被保護(hù)基材的傳遞。⑶、防火涂料受熱分解出不燃惰性氣體，沖淡被保護(hù)物體受熱分解出的可燃性氣體，使之不易燃燒或燃燒速度減慢。⑷、含氮的防火涂料受熱分解出NO、NH3等基團(tuán)，與有機(jī)游離基化合，中斷連鎖反應(yīng)，降低溫度。⑸、膨脹型防火涂料受熱膨脹發(fā)泡，形成碳質(zhì)泡沫隔熱層封閉被保護(hù)的物體，延遲熱量與基材的傳遞，阻止物體著火燃燒或因溫度升高而造成的強(qiáng)度下降。</p><p style="text-indent:25px">防火涂料噴涂法：使用壓縮空氣及噴使涂料霧化的施工方法，它的特點(diǎn)是噴涂后的涂層質(zhì)量均勻，生產(chǎn)效率高。缺點(diǎn)是有一部分涂料被損耗，同時(shí)由于溶劑的大量蒸發(fā)，影響操作者的身體健康?？諝鈬娡康年P(guān)鍵設(shè)備是噴。噴依據(jù)涂料供給方式通常分為重力式、吸引式和壓送式3種，又按噴涂能力分為小型和大型兩類。涂料黏度高，需要空氣壓力大，噴嘴應(yīng)選大口徑的；涂料黏度低，需要壓力小，噴嘴可以選小口徑的。空氣噴涂的空氣壓力一般為0.3~0.6MPa。乳液型膨脹防火涂料和溶劑型膨脹防火涂料可用于建筑物、電力、電纜的防火。防火涂料一般使用在耐火極限要求不超過2h的建筑鋼結(jié)構(gòu)上。</p><div

style="text-indent:25px">防火涂料誤區(qū)1：把木結(jié)構(gòu)防火涂料用在鋼結(jié)構(gòu)上由于木結(jié)構(gòu)防火涂料和鋼結(jié)構(gòu)防火涂料用肉眼是無法識(shí)別，消費(fèi)者選購時(shí)必須了解的防火涂料的詳細(xì)屬性。如果鋼結(jié)構(gòu)使用木結(jié)構(gòu)的防火涂料，其附著力較大下降，而且容易脫落，無法保證防火安全。誤區(qū)2未區(qū)分溶劑型和水性防火涂料鋼結(jié)構(gòu)防火涂料有兩種，溶劑型防火涂料和水性防火涂料。從附著力角度比較，溶劑型大于水性，因此，對(duì)用于室外的鋼結(jié)構(gòu)應(yīng)采用溶劑型防火涂料，室內(nèi)鋼結(jié)構(gòu)可使用溶劑型或水性防火涂料。國(guó)內(nèi)有些廠家生產(chǎn)的防火涂料，遇火時(shí)會(huì)分解出有毒氣體。如果耐火電氣產(chǎn)品使用了這種涂料，一旦失火就會(huì)釋放出有毒氣體。例如使用已被淘汰G60過氯乙烯防火涂料，遇火時(shí)會(huì)分解出有毒的氯氣，因此不能選用。防火涂料施工的好壞對(duì)材料的防火性能也有影響，因此，需重視防火涂料的涂裝質(zhì)量。不同的防火涂料的涂裝方法稍有差別，但其基本施工要點(diǎn)是相同的。防火涂料阻止物體著火燃燒或因溫度升高而造成的強(qiáng)度下降。廣州防火涂料資費(fèi)</p><p
