style="text-indent:25px">建筑防火是消防科學(xué)技術(shù)的一個(gè)重要領(lǐng)域，而防火涂料又是防火建筑材料中的重要組成部分。防火涂料是指涂裝在物體表面，可防止火災(zāi)發(fā)生，阻止火勢(shì)蔓延傳播或隔離火源，延長(zhǎng)基材著火時(shí)間或增加絕熱性能以推遲結(jié)構(gòu)破壞時(shí)間的一類涂料。按用途和使用對(duì)象的不同可分為：飾面型防火涂料、電纜防火涂料、鋼結(jié)構(gòu)防火涂料，隨州鋼結(jié)構(gòu)防火涂料、預(yù)應(yīng)力混凝土樓板防火涂料等。中國(guó)防火涂料的發(fā)展，較國(guó)外工業(yè)發(fā)達(dá)國(guó)家晚15～20年，雖然起步晚，但發(fā)展速度較快，隨州鋼結(jié)構(gòu)防火涂料。尤其是鋼結(jié)構(gòu)防火涂料，從品種類型，隨州鋼結(jié)構(gòu)防火涂料、技術(shù)性能、應(yīng)用效果和標(biāo)準(zhǔn)化程度上看，已接近或達(dá)到國(guó)際先進(jìn)水平。近幾年，其需求量成倍增長(zhǎng)，這與鋼結(jié)構(gòu)建筑的迅速發(fā)展是分不開的。防火涂料什么情況下會(huì)使其沉淀結(jié)塊?隨州鋼結(jié)構(gòu)防火涂料</p><div

防火涂料是用于可燃性基材表面，能降低被涂材料表面的可燃性、阻滯火災(zāi)的迅速蔓延，用以提高被涂材料耐火極限的一種特種涂料。施用于可燃性基材表面，用以改變材料表面燃燒特性，阻滯火災(zāi)迅速蔓延；或施用于建筑構(gòu)件上，用以提高構(gòu)件的耐火極限。防火涂料也被稱作做阻燃涂料。防火涂料的防火原理大致可歸納為以下五點(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。防火涂料種類很多，但是按照防火涂料的使用對(duì)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(hù)性材料，具有一定的裝飾性和防火性。

薄涂型：涂層厚度在3～7mm的鋼結(jié)構(gòu)防火涂料稱為薄涂型鋼結(jié)構(gòu)防火涂料。該類涂料受火時(shí)能膨脹發(fā)泡，以膨脹發(fā)泡所形成的耐火隔熱層延緩鋼材的升溫，保護(hù)鋼構(gòu)件。這類鋼結(jié)構(gòu)涂料一般是用合適的乳膠聚合物作基料，再配以阻燃劑、添加劑等組成。對(duì)這類防火涂料，要求選用的乳液聚合物必須對(duì)鋼基材具有良好附著力、耐久性和耐水性。常用作這類防火涂料基料的乳液聚合物有苯乙烯改性的丙烯酸乳液、聚醋酸乙烯乳液、偏氯乙烯乳液等。對(duì)于用水性乳液作基料的防火涂料，阻燃添加劑、顏料及填料是分散到水中的，因而水實(shí)際上起分散載體的作用，為了使粒狀的各種添加劑能更好地分散，還加入分散劑，如常用的六偏磷酸鈉等。該類鋼結(jié)構(gòu)防火涂料在生產(chǎn)過程中一般都分為3步：***步先將各種阻燃添加劑分散在水中，然后研磨成規(guī)定細(xì)度的漿料；第二步再用基料（乳液）進(jìn)行配漆；第三步在漿料中配以無機(jī)輕質(zhì)材料、增強(qiáng)材料等攪拌均勻。該涂料一般分為底層（隔熱層）和面層（裝飾層），其裝飾性比厚涂型好，施工采用噴涂，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><p> 非膨脹型防火涂料非膨脹型防火涂料包括兩個(gè)類型，即：難燃性防火涂料和不燃性防火涂料難燃性防火涂料有乳膠類防火涂料和含難燃助劑的防火涂料，乳膠類防火涂料其乳膠本身為難燃性物質(zhì)，在加上些無機(jī)顏料就形成了防火涂料，含難燃性助劑的防火涂料大多先用鹵素使基料難燃化，然后再加難燃劑，含難燃劑的防火涂料一方面由于本身的難燃性，另一方面由于這些助劑與基料的相互作用，而具有防火性能。不燃性防火涂料主要為無機(jī)涂料，這種涂料是無機(jī)基料中加入一些無機(jī)顏料及配料而形成一種完全不燃燒的防火涂料，對(duì)于這種涂料還存在著耐水性，裝飾性較差，不易固化等缺點(diǎn)，有待解決。膨脹型防火涂料與非膨脹型涂料相比，二者都是對(duì)火焰有抑制作用，但從隔熱性能看，膨脹型防火涂料是優(yōu)于非膨脹型防火涂料。常見的種類主要有裝飾性防火涂料、木質(zhì)防火涂料、鋼結(jié)構(gòu)防火涂料等。</p><div

非膨脹型鋼結(jié)構(gòu)防火涂料（厚型防火涂料）非膨脹型鋼結(jié)構(gòu)防火涂料是指涂層厚度大于7mm，小于等于45mm，呈粒狀面，密度較小，熱導(dǎo)率低，耐火極限在2h以上的鋼結(jié)構(gòu)防火涂料。由于厚型防火涂料的成分多為無機(jī)材料，因此其防火性能穩(wěn)定，長(zhǎng)期使用效果較好，但其涂料組分的顆粒較大，涂層外觀不平整，影響建筑的整體美觀，因此大多用于結(jié)構(gòu)隱蔽工程。該類防火涂料在火災(zāi)中利用材料粒狀表面，密度較小，熱導(dǎo)率低或涂層中材料的吸熱性，延緩了鋼材的溫升，保護(hù)鋼材。這類防火涂料是用合適的無機(jī)膠結(jié)料(如水玻璃、硅溶膠、磷酸鋁鹽、耐火水泥等)，再配以無機(jī)輕質(zhì)絕熱骨料材料(如膨脹珍珠巖、膨脹蛭石、海抱石、漂珠、粉煤灰等)、防火添加劑、化學(xué)藥劑和增強(qiáng)材料(如硅酸鋁纖維、巖棉、陶瓷纖維、玻璃纖維等)及填料等混合配制而成，具有成本較低的優(yōu)點(diǎn)。施工常采用噴涂，適用于耐火極限要求在2h以上的室內(nèi)外隱蔽鋼結(jié)構(gòu)、高層全鋼結(jié)構(gòu)及多層廠房鋼結(jié)構(gòu)。如：高層民用建筑的柱、一般工業(yè)與民用建筑中支承多層的柱的耐火極限均應(yīng)達(dá)到3h，需采用該厚型防火涂料保護(hù)。含氮的防火涂料受熱分解出NO，NH3等基團(tuán)，與有機(jī)游離基化和，終端鏈反應(yīng)，降低溫度。宜昌耐高溫防火涂料包工包料</p><p

隧道防火涂料是以阻燃為主的材料配置而成。該產(chǎn)品具有涂料涂層薄、耐火極限高、粘結(jié)強(qiáng)度高、耐候性能好等特點(diǎn)。適用于公路、鐵路、過街隧道以及地下工程等混凝土結(jié)構(gòu)的防火保護(hù)。而隧道防火涂料起皺問題多是以下三種情況進(jìn)行分析，從而才能夠達(dá)到效果。 </p> <p> <br /> </p> <p> <br /> </p> <p> 環(huán)境因素造成的起皺問題：涂裝時(shí)表面太熱或天氣太熱以及未固化的涂層暴露在雨、露、霧或高濕的環(huán)境下就會(huì)使得涂料難以及時(shí)干燥，造成起皺問題； </p> <p> <br /> </p> <p> 材料自身的問題造成起皺：由于涂料中添加的潤(rùn)濕劑量過少，或者添加的其他助劑量不合理可能造成涂料干燥時(shí)間過短，出現(xiàn)問題，這一情況的判斷主要是排除環(huán)境因素，可以用一塊樣品進(jìn)行試驗(yàn)，從而判斷出是否是材料的問題； </p> <p> <br /> </p> <p> 噴涂機(jī)器的問題使得出現(xiàn)起皺情況：涂料在實(shí)際的應(yīng)用過程中由于清理的不干凈就會(huì)出現(xiàn)起皺的情況； </p> <p> <br /> </p> <p> 其他原因造成起皺情況：由于隧道防火涂料在涂刷過程中涂刷過厚，不均勻也會(huì)造成出現(xiàn)起皺問題。 </p> <p> <br /> </p> <p> <br />
