說到白鐵大家可能都非常正規螺旋鍍鋅風管模糊，是不是白色的鐵就叫白鐵？其實白鐵就是大家都非常熟悉的鍍鋅鐵。鐵是我們螺旋鍍鋅風管生活(huo)中使用廣泛的(de)金屬(shu)材料，在(zai)任何地方(fang)都會有鐵(tie)的(de)使用。人們之(zhi)(zhi)所以(yi)要(yao)(yao)對鐵(tie)進行鍍(du)鋅，是(shi)因為鐵(tie)在(zai)代大氣中非常活(huo)躍，只(zhi)要(yao)(yao)本質比(bi)較(jiao)活(huo)躍的(de)金屬(shu)材料都很容易(yi)和氧氣產生化學(xue)反應(ying)，但是(shi)經(jing)過鍍(du)鋅之(zhi)(zhi)后就能夠起到保護作用，這樣就不會發生氧化現象發生。

工業中的正規螺旋鍍鋅風管主要有： (1)白鐵管道類：白螺旋鍍鋅風管廠家鐵(tie)(tie)(tie)厚(hou)鐵(tie)(tie)(tie)各(ge)種排氣，排風(feng)(feng)、吸塵管道，中央空調(diao)冷(leng)氣管，廚房抽(chou)油煙(yan)管道，保溫(wen)(wen)管、烤漆爐(lu)抽(chou)煙(yan)煙(yan)罩。 (2)白(bai)鐵(tie)(tie)(tie)工(gong)(gong)程(cheng)類：酒店(dian)餐(can)館超市工(gong)(gong)程(cheng)、車間(jian)換氣工(gong)(gong)程(cheng)、工(gong)(gong)業(廠)排風(feng)(feng)(通風(feng)(feng))凈化工(gong)(gong)程(cheng)、水簾降溫(wen)(wen)工(gong)(gong)程(cheng)。 (3)對外(wai)加工(gong)(gong)：剪板(ban)、折板(ban)、沖壓、液壓。 (4)來(lai)料加工(gong)(gong)或定做(zuo)的(de)(de)生產(chan)銷售： 各(ge)種五金白(bai)鐵(tie)(tie)(tie)制(zhi)品、鋁板(ban)、不(bu)銹鋼(gang)及各(ge)種方(fang)圓(yuan)制(zhi)品、水濂柜、不(bu)銹鋼(gang)工(gong)(gong)作(zuo)臺、貨(huo)架、水箱、吸塵桶。 我們(men)在說(shuo)(shuo)說(shuo)(shuo)白(bai)鐵(tie)(tie)(tie)煙(yan)囪(cong)的(de)(de)加工(gong)(gong)流程(cheng)：根(gen)據(ju)(ju)客(ke)戶(hu)的(de)(de)需(xu)(xu)求（圓(yuan)形還是(shi)(shi)方(fang)形），用專業的(de)(de)設(she)備(bei)進行定型(xing)，然后壓邊，繼而(er)對縫合處(chu)密封處(chu)理(li)。說(shuo)(shuo)到(dao)這里(li)，有些人就有些不(bu)賴煩了，我們(men)主(zhu)要是(shi)(shi)講(jiang)白(bai)鐵(tie)(tie)(tie)的(de)(de)好(hao)處(chu)，怎(zen)么說(shuo)(shuo)到(dao)這里(li)了呢，其(qi)實不(bu)然，我們(men)在了解(jie)它好(hao)處(chu)的(de)(de)同時，基礎是(shi)(shi)需(xu)(xu)要了解(jie)的(de)(de)，因為那些好(hao)處(chu)都(dou)是(shi)(shi)從白(bai)鐵(tie)(tie)(tie)的(de)(de)材質(zhi)而(er)言的(de)(de)。 一、耐高溫(wen)(wen)：白(bai)鐵(tie)(tie)(tie)所(suo)承受的(de)(de)溫(wen)(wen)度是(shi)(shi)35℃-600℃，還可(ke)以根(gen)據(ju)(ju)客(ke)戶(hu)需(xu)(xu)求更(geng)高； 二、方(fang)、圓(yuan)隨用戶(hu)而(er)定； 三(san)、工(gong)(gong)作(zuo)壓力強：一般在400mmWG，也可(ke)根(gen)據(ju)(ju)客(ke)戶(hu)需(xu)(xu)求更(geng)高； 四、美觀、大(da)方(fang)，可(ke)根(gen)據(ju)(ju)客(ke)戶(hu)的(de)(de)樣式制(zhi)作(zuo)（白(bai)鐵(tie)(tie)(tie)的(de)(de)可(ke)塑性更(geng)強）； 除以上(shang)之(zhi)外(wai)還有耐酸堿、阻燃、耐磨、耐拉等(deng)(deng)功能。有良好(hao)的(de)(de)防火性能和良好(hao)的(de)(de)機(ji)械強度。 白(bai)鐵(tie)(tie)(tie)在很多地方(fang)都(dou)能用到(dao)，工(gong)(gong)廠廠房、電子設(she)備(bei)、酒店(dian)、冶金、制(zhi)冷(leng)、高氣體、通風(feng)(feng)換氣、環保通風(feng)(feng)工(gong)(gong)程(cheng)之(zhi)抽(chou)放煙(yan)霧、濕氣、塵埃等(deng)(deng)，真(zhen)可(ke)謂用途多多。

支吊架不得正規螺旋鍍鋅風管安裝在風口、閥門檢查孔處，以免妨礙操作。吊架不得直接吊在法蘭上。保溫風管不能直接與支螺旋鍍鋅風管廠家吊(diao)(diao)架(jia)接觸，應墊上(shang)堅固(gu)的隔熱材料，其厚(hou)度與保溫風(feng)管(guan)厚(hou)度相同(tong)，防止產生“冷橋”。聚氯吞烯風(feng)管(guan)也與鋼板(ban)風(feng)管(guan)一樣采用(yong)支(zhi)、吊(diao)(diao)托架(jia)，但一般以吊(diao)(diao)架(jia)為主，支(zhi)架(jia)間距按下(xia)表的要求制作安(an)裝。

從重慶白鐵加正規螺旋鍍鋅風管工廠了解到，白鐵皮要比馬口鐵耐用，馬口鐵碰破一點，很快會爛掉;可是白鐵皮即使碰螺旋鍍鋅風管廠家破(po)一大塊，也不容易被銹蝕。這是(shi)因(yin)為鋅(xin)的(de)(de)(de)(de)化學性質(zhi)比鐵(tie)活潑，當外界的(de)(de)(de)(de)空(kong)氣(qi)和水份向白(bai)鐵(tie)皮“進攻”時，鋅(xin)首(shou)先(xian)與氧氣(qi)化合(he)，而保護了(le)鐵(tie)的(de)(de)(de)(de)安(an)全(quan)。 金屬鋅(xin)除了(le)用來(lai)制造白(bai)鐵(tie)皮外，也用來(lai)制造干電(dian)池的(de)(de)(de)(de)外殼(ke)。不過干電(dian)池外殼(ke)的(de)(de)(de)(de)鋅(xin)是(shi)較純的(de)(de)(de)(de)。此外，鋅(xin)也與銅(tong)制成銅(tong)鋅(xin)合(he)金——黃銅(tong)。

高壓靜電重正規螺旋鍍鋅風管慶油煙凈化方法：高壓靜電方法是由220kv電壓通過變壓器變壓至上萬伏，然后經整流器轉換螺旋鍍鋅風管廠家成(cheng)(cheng)直(zhi)流電(dian)(dian)，在(zai)(zai)兩極板間構成(cheng)(cheng)一個強電(dian)(dian)場(chang)，使(shi)煙氣中(zhong)顆(ke)(ke)粒荷(he)電(dian)(dian)，荷(he)電(dian)(dian)的油煙霧顆(ke)(ke)粒物(wu)在(zai)(zai)電(dian)(dian)極間受重力、電(dian)(dian)極引力和風場(chang)動力做用(yong).由于顆(ke)(ke)粒物(wu)的荷(he)電(dian)(dian)量(liang)隨粒徑的增(zeng)長而增(zeng)大，大顆(ke)(ke)粒受電(dian)(dian)場(chang)力的作(zuo)用(yong)大，其對氣溶膠狀態污染物(wu)的去除率相(xiang)對較高(gao)，可達80%-90%，但該法造價相(xiang)對較高(gao)，在(zai)(zai)運(yun)行維護(hu)方(fang)面(mian),相(xiang)比機械式(shi)靜電(dian)(dian)式(shi)較為簡單，而在(zai)(zai)設備價格(ge)方(fang)面(mian),靜電(dian)(dian)式(shi)投入成(cheng)(cheng)本相(xiang)比機械式(shi)要大。綜合比較而言,靜電(dian)(dian)式(shi)凈化(hua)設備優于機械式(shi)凈化(hua)設備。
