膨脹型防火涂料受熱膨脹，形成碳質(zhì)泡沫隔熱層封閉被保護(hù)的物體，十堰油性防火涂料，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。所以在選擇家用防火涂料時(shí)，一定要選購具有環(huán)保作用的綠色防火涂料。十堰油性防火涂料</p><div style="width:100%;text-align: center;"><img

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(hù)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(jī)防火涂料和無機(jī)防火涂料。對非膨脹型防火涂料來說，正是依賴于它本身的難燃性和不燃性來阻止火焰?zhèn)鞑?。所以，涂層越厚，高溫下形成的一種釉狀物也越厚，防火涂料的隔熱效果也會(huì)得到提高。對膨脹型防火涂料來說，涂層厚，受火膨脹發(fā)泡，形成隔絕氧氣和隔熱的泡沫層也愈厚，同時(shí)部分含氮防火涂料分解出的[NO]、[NH3]等基團(tuán)增多，與有機(jī)游離基化合，中斷鏈鎖反應(yīng)的效果也好。所以，從提高耐火性能來說，防火涂料處理時(shí)，涂層越厚越好。非膨脹型防火涂料主要用于木材、纖維板等板材質(zhì)的防火，用在木結(jié)構(gòu)屋架、頂棚、門窗等表面。膨脹型防火涂料有***型膨脹防火涂料、乳液型膨脹防火涂料、溶劑型膨脹防火涂料。***型膨脹防火涂料可用于保護(hù)電纜、聚乙烯管道和絕緣板的防火涂料或防火膩?zhàn)?。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。

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)。

在非膨脹型防火涂料的組成中必需含有阻燃（防火劑），如含磷、含鹵素的有機(jī)物（如十溴聯(lián)苯醚）、硼酸鈉、三氧化銻等。硼酸鈉尤其合用于用作乙酸乙烯系乳液的阻燃劑，其添加量按10%溶液計(jì)，以占聚合物的40%~60%為宜。三氧化二銻本身的阻燃能力并不算高，但當(dāng)它處在燃燒初期可以天生三氯化銻的情況下，例如在氯化石蠟并用，就會(huì)施展出優(yōu)勝的阻燃能力。為了獲得優(yōu)異的防火機(jī)能，除添加阻燃劑外，基料的選擇也很重要。因?yàn)辂u素（一般為氯和溴）和磷等元素對改進(jìn)防火性效果十分***，所以比較好選用含有這些元素的基料。例如，以氯乙烯或偏二氯乙烯共聚物乳液或氯化橡膠乳液作為基料**為優(yōu)勝。此外，要以選用磷酸三甲苯酯和β-三氯乙烯磷酸酯作為阻燃性增塑劑。膨脹型防火涂料的防火機(jī)理在于當(dāng)防火涂料的飾面層暴露于火焰上時(shí)，涂膜中的發(fā)泡性成分即受熱分解，形成隔熱性的海綿狀發(fā)泡層，從而阻止火焰的傳播。涂料中的防火助劑主要是發(fā)泡成分，包括碳源、發(fā)泡劑和有機(jī)氮化合物等，它們可以配合使用。武漢防火涂料廠家直銷，來電咨詢。十堰油性防火涂料</p><p
