用來去除鋼管表面的氧化鐵，酸洗后，通過氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅鋼管是鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅鐵合金層。合金層與純鋅層、鋼管基體融為一體，因此熱鍍鋅鋼管具有鍍層均勻、附著力強(qiáng)、使用壽命長等優(yōu)點(diǎn)。2、冷鍍鋅管/冷鍍鋅鋼管冷鍍鋅就是電鍍鋅，鍍鋅量很少，只有10-50g/m2，其本身的耐腐蝕性比熱鍍鋅管相差很多。正規(guī)的鍍鋅管生產(chǎn)廠家，為了保證質(zhì)量，大多不采用電鍍鋅(冷鍍鋅)。只有那些規(guī)模小、設(shè)備陳舊的小企業(yè)采用電鍍鋅，當(dāng)然他們的價格也相對便宜一些。二、鍍鋅管的生產(chǎn)工藝流程鍍鋅鋼管的生產(chǎn)工藝屬于各生產(chǎn)廠家的機(jī)密，因此只能提供大致工藝流程：a.圓鋼準(zhǔn)備;b.加熱;c.熱軋穿孔;d.切頭;e.酸洗;f.修磨;g.潤滑;h.冷軋加工;i.脫脂;j.固溶熱處理;k.矯直;l.切管;m.酸洗;n.成品檢驗(yàn)。三、鍍鋅管的技術(shù)要求與標(biāo)1、牌號和化學(xué)成分鍍鋅管鍍鋅鋼管用鋼的牌號和化學(xué)成分應(yīng)符合GB-3092所規(guī)定的黑管用鋼的牌號和化學(xué)成分。2、鍍鋅管的制造方法鍍鋅管的制造方法(爐焊或電焊)由制造廠選擇。鍍鋅多采用熱浸鍍鋅法。3、鍍鋅管的螺紋及管接頭。肥西冷拔鍍鋅鋼管制造廠家管道試壓的壓力值，持壓時間，試壓合格標(biāo)準(zhǔn)應(yīng)按設(shè)計(jì)及有關(guān)標(biāo)準(zhǔn)規(guī)范執(zhí)行。</p><div

90年代以后，由于國家對環(huán)境保護(hù)的重視，對高污染企業(yè)控制越來越嚴(yán)，熱鍍鋅管在生產(chǎn)中產(chǎn)生的“三廢”難以解決，再加上不銹鋼焊管、PVC管和復(fù)合管等管材的快速發(fā)展，以及國家提倡推廣應(yīng)用化學(xué)建材，限制使用鍍鋅鋼管，使得熱鍍鋅焊管的發(fā)展受到了很大的約束和限制，熱鍍鋅焊管后來發(fā)展緩慢[1]。冷鍍鋅鋼管鋅層是電鍍層，鋅層與鋼管基體**分層。鋅層較薄，鋅層簡單附著在鋼管基體上，容易脫落。故其耐腐蝕性能差。在新建住宅中，禁止使用冷鍍鋅鋼管作為給水管。相關(guān)利用/鍍鋅管編輯為提高鋼管的耐腐蝕性能，對一般鋼管進(jìn)行鍍鋅。鍍鋅鋼管分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，電鍍鋅成本低，表面不是很光滑。吹氧焊管：用作煉鋼吹氧用管，一般用小口徑的焊接鋼管，規(guī)格由3/8-2寸八種。用08、10、15、20或者195-Q235的鋼帶制作成的，為了防腐蝕，有的要進(jìn)行有效滲鋁處理。鍍鋅管老房子大部分是用的都是鍍鋅管，現(xiàn)在煤氣、暖氣用的那種鐵管也是鍍鋅管，鍍鋅管作為水管，使用幾年后，管內(nèi)產(chǎn)生大量銹垢，流出的黃水不僅污染潔具，而且夾雜著不光滑內(nèi)壁滋生的細(xì)菌，銹蝕造成水中重金屬含量過高，嚴(yán)重危害人體的健康。六七十年代，國際上發(fā)達(dá)國家開始開發(fā)新型管材。</p><p> 獨(dú)特的清潔生產(chǎn)鍍鋅管采用***鹽電鍍鋅鐵合金工藝，在于生產(chǎn)線槽與槽間均穿孔直通而溶液無任何帶出或溢流。生產(chǎn)過程各工序由循環(huán)系統(tǒng)組成，各槽溶液即酸堿液、電鍍液、出光與鈍化液等，只循環(huán)回用不向系統(tǒng)外滲漏或排放，生產(chǎn)線只設(shè)5個清洗槽，采用循環(huán)回用定期排放，特別是鈍化后不清洗的無廢水產(chǎn)生的生產(chǎn)工藝。電鍍設(shè)備的特殊性鍍鋅管的電鍍銅線材電鍍一樣，都屬于連續(xù)電鍍，但施鍍的設(shè)備不同。鐵絲以其細(xì)長的條形特色而設(shè)計(jì)的鍍槽，槽體長而寬卻淺。電鍍時鐵絲從孔眼穿出，呈一字形在液面展開，保持相互間距。而鍍鋅管卻又不同于鐵絲，有其獨(dú)特之處，槽設(shè)備較為復(fù)雜。槽體由上、下兩部分組成，上部為鍍槽，下部為溶液循環(huán)儲存槽，形成一個上窄下寬狀、似梯形的槽體，在鍍槽中設(shè)有鍍鋅管電鍍運(yùn)行的通道，槽底有兩個通孔與下部的儲存槽相通，并與液下泵形成鍍液循環(huán)復(fù)用系統(tǒng)。因此，鍍鋅管同鐵絲電鍍一樣，鍍件都是動態(tài)性的，而與鐵絲電鍍不同之處，電鍍鍍鋅管的鍍液也是動態(tài)性的。生產(chǎn)工藝/鍍鋅管編輯黑件檢查→掛料→脫脂→漂洗→酸洗→清洗→浸漬助鍍劑→熱空氣烘干→熱浸鍍鋅→內(nèi)外吹→冷卻→鈍化和漂洗→卸料→檢驗(yàn)、修整→打字標(biāo)識→包裝入庫、運(yùn)輸。鍍鋅線管是**穿線管，鍍鋅鋼管是水煤氣鋼管。</p><div
