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%。**開放以來，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)問題曾一度被人們忽視，荊門飾面型防火涂料噴涂。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%，荊門飾面型防火涂料噴涂，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，荊門飾面型防火涂料噴涂。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。油性防火涂料他的油劑有汽油、**，有一些揮發(fā)性易燃易爆的成分在里面，所以它存在一定的火災(zāi)危險(xiǎn)。荊門飾面型防火涂料噴涂</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。

磷酸鹽類黏結(jié)劑也是常用的無(wú)機(jī)黏結(jié)劑，用它作為防火涂料的基料時(shí)，避免了堿性氧化物與空氣中的酸性氣體反應(yīng)的問題，從而提高了涂料的耐候性、耐水性等理化性能指標(biāo)。但是，磷酸鹽類黏結(jié)劑中M/P的摩爾比（M指金屬，P是磷）對(duì)涂料的貯存穩(wěn)定性、耐水性以及涂料與鋼基材的黏結(jié)力等各項(xiàng)性能都有直接的影響。因此，在以磷酸鹽為基料的鋼結(jié)構(gòu)防火涂料的研制中，基料摩爾比的控制是很重要的。由于厚型鋼結(jié)構(gòu)防火涂料的涂層厚而且用量多，增加建筑物自重。因此，在涂料應(yīng)注意加入一些輕質(zhì)材料和高效隔熱骨料以降低涂料的密度。用得**多的輕質(zhì)隔熱骨料主要是膨脹蛭石和膨脹珍珠巖。武漢防火涂料出廠價(jià)格是多少？孝感隧道防火涂料公司</p><p
