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。</p><p style="text-indent:25px">在高速發(fā)展的建筑中，采用混凝土的建筑結(jié)構(gòu)十分普遍，其中，預(yù)應(yīng)力鋼筋混凝土比普通鋼筋混凝土的抗裂性、剛度、抗剪性和穩(wěn)定性更好，質(zhì)量更輕，并能節(jié)省混凝土和鋼材。但是，應(yīng)用較多的預(yù)應(yīng)力鋼筋混凝土空心樓板的耐火性能很差，其原因是：預(yù)應(yīng)力鋼筋的溫度達(dá)200℃時(shí)，屈服點(diǎn)開(kāi)始下降，300℃時(shí)，預(yù)應(yīng)力幾乎全部消失，蠕變加快，致使預(yù)應(yīng)力板的強(qiáng)度、剛度迅速降低，從而板中的撓度變化加快，板下面出現(xiàn)裂縫，預(yù)應(yīng)力鋼筋直接受到高溫作用，其剛度和強(qiáng)度進(jìn)一步下降，混凝土在高溫下性能也在改變，板下的混凝土受熱膨脹方向與板受拉方向一致，助長(zhǎng)了板中撓度的變化?；炷猎?00℃時(shí)，強(qiáng)度開(kāi)始下降，500℃強(qiáng)度降低一半左右，800℃強(qiáng)度幾乎喪失。在建筑火災(zāi)中，這類(lèi)樓板均在0.5h左右即斷裂垮塌。如何選購(gòu)防火涂料廠家？</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(chēng)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(lèi)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(lái)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。
