真假的區(qū)別，當(dāng)然不止是山寨那么簡單。在消防領(lǐng)域，也有不法商家造假冒偽劣消防器材！試想一下，發(fā)生火災(zāi)后，防火門不防火，滅火器也不能用，那得多***啊……<br/> 還是跟隨小編的步伐，<br/> 學(xué)學(xué)真假消防器材的辨別方法吧，<br/> Get 此項(xiàng)技能，<br/> 你就是這條街**亮的仔！<br/> 如何辨別消防器材真假？<br/> 一、查看產(chǎn)品標(biāo)識(shí)<br/> 一般來說，市面上賣的比較好的家用消防器材有滅火器、逃生繩、逃生面罩，防毒面具、防火毯等，隨著網(wǎng)絡(luò)的普及,網(wǎng)購作為一種方便、快捷的購物方式越來越被廣大網(wǎng)民朋友所接受,由于網(wǎng)上交易方便快捷,沒有地區(qū)限制,選擇范圍廣,**重要的是價(jià)格較為低廉,因此吸引一些私營單位和個(gè)人的目光和購買。小編建議大家購買消防產(chǎn)品比較好到有規(guī)模、有銷售資質(zhì)的實(shí)體店購買，并且在選購時(shí)一定要仔細(xì)檢查產(chǎn)品的名稱，廠名廠址，產(chǎn)品的型號(hào)規(guī)格，宿州建支瑪鋼管件供應(yīng)商、編號(hào)，宿州建支瑪鋼管件供應(yīng)商、商標(biāo)、生產(chǎn)日期、主要技術(shù)指標(biāo)、執(zhí)行標(biāo)準(zhǔn)代號(hào)、使用方法，宿州建支瑪鋼管件供應(yīng)商、保質(zhì)期等內(nèi)容，滅火器和應(yīng)急燈還要有消防產(chǎn)品身份證標(biāo)識(shí)。<br/> 瑪鋼管件全程采取六檢二查一驗(yàn)的嚴(yán)格檢驗(yàn)過程。宿州建支瑪鋼管件供應(yīng)商</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="宿州建支瑪鋼管件供應(yīng)商,瑪鋼管件"

白心可鍛鑄鐵，將碳、硅含量較低的白口鑄鐵密封在氧化介質(zhì)中，在950～1050℃溫度下保持幾十個(gè)小時(shí)進(jìn)行脫碳退火處理，就得到外層為鐵素體、中心殘留著少量珠光體和團(tuán)絮狀石墨的顯微組織。其心部斷口呈白色，故稱為白心可鍛鑄鐵。黑心可鍛鑄鐵，將碳、硅含量較低的白口鑄鐵放在中性介質(zhì)中進(jìn)行石墨化處理后，在850～950℃溫度下保持幾十小時(shí)，爐內(nèi)冷卻至720～740℃再保溫十幾小時(shí)，得到鐵素體基體和團(tuán)絮狀石墨的鐵素體黑心可鍛鑄鐵；或在850～950℃下保溫十幾小時(shí)后出爐，空氣中冷卻，得到珠光體基體和團(tuán)絮狀石墨的珠光體黑心可鍛鑄鐵。鍍鋅瑪鋼常用于制造汽車后橋、彈簧支架、低壓閥門、管接頭、工具扳手等。珠光體可鍛鑄鐵常用來制造動(dòng)力機(jī)械和農(nóng)業(yè)機(jī)械的耐磨零件，國際上有用于制造汽車凸輪軸的例子。鐵素體可鍛鑄鐵廣大用于汽車、拖拉機(jī)的輪圈、差速器殼和底盤零件，機(jī)床附件中的扳手，輸電線路中的瓷瓶鐵帽、線夾、碗頭排板，紡織機(jī)械中的粗紡機(jī)和印花機(jī)盤頭以及水油管道中的彎頭、三通、接頭、中壓閥門等。珠光體可鍛鑄鐵用于氣閥搖桿、加煤機(jī)零件、高壓接頭閥體和汽車工業(yè)撥叉、差動(dòng)齒輪箱等。白心可鍛鑄鐵用于汽車零件吊架、駕駛盤柱叉肩、紡織機(jī)零件等。</p><p style="text-indent:25px">瑪鋼管件化學(xué)成分選擇：瑪鋼管件原鐵液的化學(xué)成分和熔煉過程有相似之處。原鐵水的碳當(dāng)量一般選用稍過共晶成分,w(CE)為4.3%-4.7%。過共晶鐵水有石墨漂浮傾向。為了避免這種現(xiàn)象發(fā)生,需要根據(jù)鑄件壁厚來選擇碳當(dāng)量和碳含量。壁厚小于15mm的鑄件，碳當(dāng)量應(yīng)偏于上限，如w（CE)為4.6%-4.7%,w(c）為 3.5%-3.8%。厚壁鑄件的碳當(dāng)量應(yīng)偏于下限，w(CE)為4.3%-4.4%,w(C）為3.4%-3.6%。熔制高碳當(dāng)童原鐵水是必要的,既能提高蠕化率、降低白口傾向，又能改善鐵水流動(dòng)性、防止鑄件產(chǎn)生縮松缺點(diǎn)，提高碳當(dāng)量會(huì)使瑪鋼管件強(qiáng)度有所降低,但是碳當(dāng)**對(duì)強(qiáng)度的影響遠(yuǎn)比灰鑄鐵小。承插焊管件，螺紋管件，防腐襯塑鋼制管道管件.</p><div
