防火門(mén)骨架和門(mén)扇邊框處往往是填充薄弱處，防火門(mén)運(yùn)輸中收到磕碰或撞擊，龍骨或邊框處的門(mén)芯材料容易碎裂或下沉，造成縫隙，影響防火門(mén)的隔熱性。另外，鋼質(zhì)防火門(mén)的龍骨為鋼材，導(dǎo)熱性強(qiáng)，同時(shí)該位置耐火材料厚度會(huì)減少，容易將熱量從受火面?zhèn)鬟f至背火面，龍骨處溫度較高，門(mén)芯板易粉化，導(dǎo)致背火面超溫。解決方法：在防火門(mén)芯外整體設(shè)置防火板，或在龍骨附近單獨(dú)設(shè)置防火板條，注意單獨(dú)設(shè)置的防火板條要比龍骨略寬。標(biāo)準(zhǔn)對(duì)門(mén)框背火表面比較高溫升的要求由180℃提高至360℃，標(biāo)準(zhǔn)較大降低，但門(mén)框的隔熱性問(wèn)題也不容易忽視。門(mén)框背火面熱量主要來(lái)源于兩個(gè)方面：門(mén)框材料本身對(duì)熱量的傳導(dǎo)和門(mén)縫處熱量的傳導(dǎo)。解決方法：減少門(mén)框材料本身的熱量傳導(dǎo)。木質(zhì)防火門(mén)選擇熱傳導(dǎo)率較低或耐火性能好的木材，也可以在門(mén)框表面粘貼防火板。鋼質(zhì)防火門(mén)可以門(mén)框中間用防火板、隔熱材料或開(kāi)槽的方式設(shè)置熱量斷橋。減少縫隙處熱量傳導(dǎo)。可以增大搭接量，多設(shè)置密封條或設(shè)置多道密封條。耐火完整性是指在標(biāo)準(zhǔn)耐火試驗(yàn)條件下，防火門(mén)當(dāng)某一面受火時(shí)，在一定時(shí)間內(nèi)阻止火焰和熱氣穿透或在背火面出現(xiàn)火焰的能力。甘肅工業(yè)平開(kāi)門(mén)價(jià)格且該防火卷簾門(mén)提升到位后應(yīng)能自動(dòng)恢復(fù)原關(guān)閉狀態(tài)。</p><div

style="text-indent:25px">影響防火門(mén)耐火完整性和隔熱性的因素：目前門(mén)芯材料大多采用膨脹珍珠巖、發(fā)泡水泥、氧化鎂氯化鎂珍珠巖混合物等材料，這些材料的導(dǎo)熱系數(shù)、強(qiáng)度、腐蝕性、含水率等都會(huì)直接影響防火門(mén)的耐火性能。導(dǎo)熱系數(shù)決定了門(mén)芯材料的隔熱效果，導(dǎo)熱系數(shù)越低，熱傳導(dǎo)速度就越慢，門(mén)芯板就可以做的更薄，反之亦然。所以在設(shè)計(jì)門(mén)芯板厚度時(shí)，先要了解門(mén)芯材料的導(dǎo)熱系數(shù)，有時(shí)門(mén)芯材料受熱后會(huì)發(fā)生化學(xué)反應(yīng)，其導(dǎo)熱系數(shù)也會(huì)發(fā)生很大的變化，設(shè)計(jì)時(shí)也要充分考慮這個(gè)因素。如果防火門(mén)芯板的導(dǎo)熱系數(shù)過(guò)高或門(mén)芯板厚度過(guò)低就會(huì)造成門(mén)扇的整體隔熱性很差，會(huì)出現(xiàn)平均溫升>140℃的情況。門(mén)芯強(qiáng)度包括抗裂強(qiáng)度和抗彎強(qiáng)度?？沽褟?qiáng)度高可以保證其在運(yùn)輸過(guò)程中不易破碎，如果門(mén)芯板出現(xiàn)裂縫或破碎無(wú)疑是致命性的，會(huì)造成門(mén)扇局部或整體超溫，影響防火門(mén)的隔熱性能。解決方法：增大門(mén)芯密度和強(qiáng)度，在門(mén)扇內(nèi)加龍骨。門(mén)芯腐蝕性對(duì)防火門(mén)特別是鋼質(zhì)防火門(mén)影響非常嚴(yán)重，部分門(mén)芯材料或防火膠水含有大量氯離子，容易與鋼板發(fā)生化學(xué)反應(yīng)，鋼質(zhì)門(mén)面板會(huì)發(fā)生銹蝕和腐爛，導(dǎo)致面板逐漸與門(mén)芯板分離，這也會(huì)嚴(yán)重影響防火門(mén)的隔熱性能。解決方法：鋼板采用鍍鋅鋼板，或在門(mén)芯板外面加一次防火板。</p><p

style="text-indent:25px">防火門(mén)是建筑物防火分隔的主要設(shè)施之一，通常設(shè)置在防火墻、樓梯間出入口或管道井開(kāi)口部位。防火門(mén)除具有普通門(mén)的作用外，更具有阻止火勢(shì)蔓延和煙氣擴(kuò)散的作用，可在一定時(shí)間內(nèi)阻止火勢(shì)的蔓延，確保人員疏散，也為救援人員爭(zhēng)取救援時(shí)間。一旦發(fā)生火災(zāi)，防火門(mén)是保護(hù)人們生命財(cái)產(chǎn)安全的一道防護(hù)門(mén)，可是不合格防火門(mén)在火災(zāi)發(fā)生的時(shí)候不能防火，有的反而會(huì)讓火勢(shì)更大，加速火勢(shì)蔓延。這樣的防火門(mén)使逃生通道成了一條不歸路。據(jù)了解，現(xiàn)在市場(chǎng)上有很多不合格的“山寨”防火門(mén)產(chǎn)品，而一部分店主卻根本不知道什么是防火門(mén)，只是簡(jiǎn)單的認(rèn)為只要是鋼質(zhì)的就可以防火，更有甚者有的商家居然明目張膽地推銷(xiāo)假冒防火門(mén)，視**生命財(cái)產(chǎn)如無(wú)物，所以大家在購(gòu)買(mǎi)時(shí)一定要嚴(yán)格把關(guān)。對(duì)于質(zhì)量過(guò)關(guān)的防火門(mén)是有防火時(shí)間、耐溫極限等一系列標(biāo)準(zhǔn)規(guī)范的。人們?cè)谫?gòu)買(mǎi)防火門(mén)之前可以從網(wǎng)上下載相關(guān)文件。公安部消防局對(duì)新出的防火門(mén)都有一個(gè)資質(zhì)認(rèn)證標(biāo)準(zhǔn)，會(huì)有詳細(xì)的合格企業(yè)名單。若有不合格的企業(yè)，相關(guān)部門(mén)會(huì)進(jìn)行披露，隨之網(wǎng)上也會(huì)對(duì)其進(jìn)行曝光。蘭州電動(dòng)卷簾門(mén)定制</p></p><br
