2009年9月25日，為有效防止建筑外墻外保溫系統(tǒng)引起的火災事故，公安部、住房和城鄉(xiāng)建設部聯(lián)合制定了《民用建筑外保溫系統(tǒng)及外端裝飾防火暫行規(guī)定》(公通字〔2009)46號)(以下簡稱46號文)。本規(guī)定是為引導建筑外端保溫材料行業(yè)健康發(fā)展，在消防安全方面開出的劑。然而，開出之后，病情不但沒有得到緩解，而且以多處復發(fā)的趨勢蔓延。建筑外墻保溫材料和防火安全從“行業(yè)之爭”正式上升到不得不加強干預的“政策之重”。 </p> <p> 2011年3月14日，公安部消防局下發(fā)的公消〔2011)65號文件(以下簡稱65號文)，對容易造成防火問題的外墻保溫材料選用進行臨時**，規(guī)定在新標準發(fā)布前，從嚴執(zhí)行46號文的第二條規(guī)定，民用建筑外墻保溫材料采用燃燒性能為A級的材料。非A級保溫材料不得上墻。 </p> <p> 65號文被稱為“史上嚴消防令”。 </p> <p> <br /> </p> <p> <br /> </p><p> 中國作為四大文明古國，有著悠久燦爛的歷史文化，在防火技術方面也曾是世界先進水平。在中國早些時候，其實并沒有明確的阻燃概念，提出來的是“防火”。 </p> <p> 有道是：建業(yè)千日功，火燒當日窮。 </p> <p> 火災是自然災害中出現(xiàn)頻率比較高的災害之一，也是一種不受時空限制、破壞性巨大的災害。火出現(xiàn)在遠古時期，它帶給人類光明以及生存的可能性，從它的出現(xiàn)開始，似乎就奠定了它在人類社會歷史中不可置疑的地位。但那只是遙遠的過去，現(xiàn)在的人們對于火有了不同的認知，經(jīng)過相當長歲月的變遷，人們不僅了解到了火的用途，用勤勞的雙手以及智慧的頭腦使用火焰，駕馭火焰，給生活帶來便利，給發(fā)展帶來機會；與此同時，人們也在漫長的歲月中見識到了火的不確定性，火焰的可怕性，火災的出現(xiàn)帶給人們不可磨滅的傷害。阻燃型鋁塑板和防火鋁復合板產(chǎn)品的突出特性為:防火性能優(yōu)越。</p><div

從事電線電纜行業(yè)的人對于zr是再熟悉不過了，zr**就是阻燃的意思。大部分的電線電纜規(guī)格型號前都有一個zr或者za、zb、zc等的字眼，對于電纜購買者的我們，za、zb、zc到底**什么含義呢？我們來說說電纜的阻燃級別劃分，什么是電線電纜阻燃等級？電線電纜阻燃等級是怎么分的呢？字符“zr”是阻燃的意思，阻燃分a、b、c三級，za就**a級阻燃，zb就**b級阻燃，zr默認為c級阻燃。這對于電線電纜防火阻燃來說是一個比較方便簡潔的方式來說明不同的等級。

style="text-indent:25px">如今阻燃/防火的發(fā)展早已日新月異，一大批先進的防火/阻燃技術以及相關標準已經(jīng)應用于生產(chǎn)和生活中。江蘇建材防火等級檢測單位</p><p> 建筑物的耐火等級分為四級。建筑物的耐火等級是由建筑構(gòu)件（梁、柱、樓板、墻等）的燃燒性能和耐火極限決定的。一般說來：一級耐火等級建筑是鋼筋混凝土結(jié)構(gòu)或磚墻與鋼混凝土結(jié)構(gòu)組成的混合結(jié)構(gòu)；二級耐火等級建筑是鋼結(jié)構(gòu)屋架、鋼筋混凝土柱或磚墻組成的混合結(jié)構(gòu)；三級耐火等級建筑物是木屋頂和磚墻組成的磚木結(jié)構(gòu)；四級耐火等級是木屋頂、難燃燒體墻壁組成的可燃結(jié)構(gòu)。防火材料可分為四級：不燃性B1級，難燃性B2級，可燃性B3級，易燃性。
