鋼材是一種不會(huì)燃燒的建筑材料。跟混凝土相比,鋼材具有抗震、抗彎等諸多優(yōu)點(diǎn)。所以在現(xiàn)代建筑中,鋼結(jié)構(gòu)被廣泛應(yīng)用,不**可以相對(duì)增加建筑物的荷載能力,也可以滿足建筑設(shè)計(jì)美感造型的需要,如各種單層或多層廠房、摩天大樓、庫(kù)房、候車室、候機(jī)廳等都普遍采用鋼結(jié)構(gòu)設(shè)計(jì)。沒(méi)加保護(hù)的鋼結(jié)構(gòu)燃燒后場(chǎng)景?沒(méi)加保護(hù)的鋼結(jié)構(gòu)燃燒場(chǎng)景?雖然鋼材不會(huì)燃燒,但鋼材遇到高溫會(huì)發(fā)生變形,導(dǎo)致結(jié)構(gòu)坍塌。鋼材作為建筑材料在防火方面又存在一些難以避免的缺點(diǎn)。一般不加保護(hù)的鋼結(jié)構(gòu)的耐火極限為15分鐘左右。通常在450～650℃溫度中就會(huì)失去承載能力,發(fā)生很大的形變,導(dǎo)致鋼柱、鋼梁彎曲甚至于結(jié)構(gòu)坍塌。在我們身邊,時(shí)常發(fā)生讓人觸目驚心的火災(zāi),造成巨大的生命和財(cái)產(chǎn)損失。北京,央視北配樓大火上海,靜安區(qū)公寓大火廣州,建業(yè)大廈大火......2013年,上海市發(fā)生9596起火災(zāi),死亡73人,直接損失.......發(fā)生火災(zāi)時(shí),防火涂料能抵御高溫,延長(zhǎng)逃生和救援時(shí)間。因此,鋼結(jié)構(gòu)需要防火涂料來(lái)進(jìn)行保護(hù)。在發(fā)生火災(zāi)的時(shí)候來(lái)抵御高溫,在一定的時(shí)間內(nèi)保護(hù)鋼結(jié)構(gòu)不變形不坍塌,延長(zhǎng)人員的逃生及消防救援的時(shí)間。防火涂料按受火后狀態(tài)分為兩類:膨脹性和非膨脹型1.膨脹型防火涂料膨脹型防火涂料在受火時(shí)。 </p> <p> <br /> </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(wú)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(wú)機(jī)涂料，這種涂料是無(wú)機(jī)基料中加入一些無(wú)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。如何分辨防火涂料的真?zhèn)危?/p><div

style="text-indent:25px">鋼結(jié)構(gòu)作為高層建筑結(jié)構(gòu)的一種形式，以其強(qiáng)度高、質(zhì)量輕，并有良好的延伸性、抗震性和施工周期短等特點(diǎn)，在建筑業(yè)中得到廣泛應(yīng)用，尤其在超高層及大跨度建筑等方面顯示出強(qiáng)大的生命力。截止1990年底，世界上高200m以上的100棟超高層建筑中鋼結(jié)構(gòu)占了79%。**開(kāi)放以來(lái)，隨著國(guó)際間技術(shù)交流與合作的加強(qiáng)，鋼結(jié)構(gòu)應(yīng)用技術(shù)在中國(guó)得到了蓬勃發(fā)展，高層和超高層建筑迅速增長(zhǎng)。據(jù)1995年的統(tǒng)計(jì)資料，中國(guó)建成的100幢超高層建筑中鋼結(jié)構(gòu)占37%，多數(shù)是近幾年興建的。隨著中國(guó)城市規(guī)模的發(fā)展，鋼結(jié)構(gòu)在中國(guó)建筑業(yè)的應(yīng)用具有非常廣闊的前景。但由于鋼結(jié)構(gòu)自身不燃，鋼結(jié)構(gòu)的防火隔熱保護(hù)問(wèn)題曾一度被人們忽視。根據(jù)國(guó)內(nèi)外有關(guān)資料報(bào)道及有關(guān)機(jī)構(gòu)的試驗(yàn)和統(tǒng)計(jì)數(shù)字表明，鋼結(jié)構(gòu)建筑的耐火性能較磚石結(jié)構(gòu)和鋼筋混凝土結(jié)構(gòu)差。鋼材的機(jī)械強(qiáng)度隨溫度的升高而降低，在500℃左右，其強(qiáng)度下降到40%～50%，鋼材的力學(xué)性能，諸如屈服點(diǎn)、抗壓強(qiáng)度、彈性模量以及荷載能力等都迅速下降，很快失去支撐能力，導(dǎo)致建筑物垮塌。因此，對(duì)鋼結(jié)構(gòu)進(jìn)行保護(hù)勢(shì)在必行。鋼結(jié)構(gòu)防火涂料刷涂或噴涂在鋼結(jié)構(gòu)表面，起防火隔熱作用，防止鋼材在火災(zāi)中迅速升溫而降低強(qiáng)度，避免鋼結(jié)構(gòu)失去支撐能力而導(dǎo)致建筑物垮塌。防火涂料生產(chǎn)廠家有哪些？襄陽(yáng)倉(cāng)庫(kù)防火涂料公司</p><p
