白鐵,在我們的日常正規螺旋鍍鋅風管生活中隨處可見,抽風管在家里都能看見。因為盡管它包含相對活躍鋅元素,但添加一些外部螺旋鍍鋅風管定制因素,實際上這種鐵(tie)是(shi)相對(dui)穩(wen)定的(de)(de)。一般來說,鐵(tie)很少直(zhi)接使用,在使用前應進行處理(li)。隨著社會的(de)(de)發展和進步,白鐵(tie)加(jia)工并不是(shi)盲目的(de)(de)沒有什么科(ke)學技術,像成都余記白鐵(tie)加(jia)工這樣的(de)(de)加(jia)工廠到處都是(shi)。

那么白鐵風正規螺旋鍍鋅風管管的一般制作標準有哪些： 制作白鐵風管前首先螺旋鍍鋅風管定制要(yao)檢查采用的(de)(de)(de)材料是否(fou)符(fu)合(he)質量(liang)要(yao)求，有否(fou)出廠合(he)格(ge)證(zheng)明(ming)書或質量(liang)鑒定文件。若無(wu)上述證(zheng)明(ming)文件則應(ying)進(jin)行外觀檢查，并應(ying)符(fu)合(he)下列要(yao)求： 1.板材表面(mian)應(ying)平整(zheng)，厚度(du)應(ying)均勻，無(wu)凸凹及明(ming)顯的(de)(de)(de)壓(ya)傷現(xian)象，并不(bu)得有裂紋、砂眼(yan)、結(jie)疤及刺邊和(he)銹蝕情況； 2.型鋼應(ying)該等(deng)型、均勻，不(bu)應(ying)有裂紋、氣泡、窩(wo)穴(xue)及其(qi)(qi)他(ta)影響(xiang)質量(liang)的(de)(de)(de)缺陷； 3.其(qi)(qi)他(ta)材料不(bu)能因(yin)具有缺陷導致(zhi)成品強度(du)的(de)(de)(de)降低(di)或影響(xiang)其(qi)(qi)使用效能。

耐高溫通風正規螺旋鍍鋅風管管的安裝必須具備一定條件才能進行，對明裝或在技術夾層內安裝的風管，應在通風管道安裝螺旋鍍鋅風管定制部位的土建工(gong)程或主體工(gong)程及地評(ping)，粉刷完工(gong)以后(hou)進(jin)行，如果通風管(guan)道(dao)安裝后(hou)，在進(jin)行土建及其他工(gong)作，可能會(hui)損(sun)壞通風管(guan)道(dao)，特(te)別是空氣潔凈系(xi)統，將會(hui)使管(guan)道(dao)內受(shou)到(dao)污(wu)染。
