其實(shí)鍍鋅圓管的分類并不復(fù)雜，只有熱鍍鋅和電鍍鋅兩種。熱鍍鋅有濕法、干法、鉛鋅法、氧化還原法等，不同熱鍍鋅方法的主要區(qū)別在鋼管酸浸清洗后，用什么方法活化管體表面提高鍍鋅質(zhì)量，現(xiàn)生產(chǎn)中主要采用干法和氧化還原法。電鍍鋅在技術(shù)上有一定的復(fù)雜性，但對(duì)單面鍍層，內(nèi)外表面鍍層厚度不同的雙面鍍層，以及薄壁管鍍鋅等皆須采用此法。 </p> <p> 鋼管應(yīng)在鍍鋅前進(jìn)行處理：即酸洗、清洗、洗滌、浸涂溶劑、干燥。酸洗時(shí)間一般為30-60分鐘；酸洗后，用吊車將鋼管吊至清洗槽進(jìn)行清洗；水滴干燥后，將鋼管吊至溶劑罐中浸泡約一分鐘；為了提高鋼管溶劑中預(yù)鍍的效果，溶劑始終保持弱堿性，然后用吊車吊至干燥爐平臺(tái)，在干燥爐中干燥。干燥溫度為100-130℃，時(shí)間一般為6-10分鐘。<span style="display:none;"></span> </p> <p> 鋼管進(jìn)行鍍鋅處理，目的是提高鋼管的防腐性能，鋅是用來(lái)防銹的，但是是鋅本身也氧化，只是氧化的速度比鐵慢，如果當(dāng)鋼管鍍鋅完畢以后再進(jìn)行防腐處理后的耐久度會(huì)更長(zhǎng)。鍍鋅鋼管防腐處理外壁工藝主要有環(huán)氧煤瀝青防腐、3PE防腐、環(huán)氧樹(shù)脂防腐等，內(nèi)壁防腐工藝有IPN8710、水泥砂漿等工藝。昆明6米鍍鋅圓管多少錢一米鍍鋅圓管廠家供應(yīng)，云南贛僑貿(mào)易供應(yīng)。</p><div

鍍鋅圓管鍍鋅特點(diǎn)要求，鍍鋅圓管鋅鍍層的外觀呈青白色，標(biāo)準(zhǔn)電極電位為-0.76V，易溶于酸，溶于堿，是典型的兩性金屬。鋅在干燥空氣中幾乎不發(fā)生變化，鋅腐蝕的臨界濕度大于70%，因此在潮濕大氣中能與二氧化碳和氧作用生成一層主要由堿式碳酸鋅組成的薄膜，這層膜有一定的緩蝕作用，鋅與硫化氫等含硫化物起反應(yīng)生成硫化鋅﹔鋅易受氯離子浸蝕，故在海水中不穩(wěn)定。 </p> <p> 鍍鋅圓管的鋅在密閉或通風(fēng)不良，空氣潮濕的條件下，與非金屬材料的揮發(fā)物(低分子羧酸，醛，酚，氨等)接觸時(shí)，鋅易遭腐蝕，生成白色疏松的腐蝕產(chǎn)物，俗稱”白霜”。鋅在高溫，高濕，密閉條件下，與膠木，油漆，木材釋放的揮發(fā)物接觸，鋅有生長(zhǎng)細(xì)絲狀單晶的傾向，俗稱”長(zhǎng)毛” 。熱鍍鋅圓管是使熔融金屬與鐵基體反應(yīng)生成合金層，使基體和鍍層結(jié)合在一起。昆明官渡區(qū)6米鍍鋅圓管價(jià)格查詢</p><p style="text-indent:25px">鍍鋅圓管哪家便宜，云南贛僑貿(mào)易供應(yīng)。昆明官渡區(qū)114鍍鋅圓管市場(chǎng)行情</p><p> 熱鍍鋅鋼管 </p> <p> 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)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。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(jiǎn)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。 </p> <p> 鍍鋅鋼管的用途 </p> <p> 常說(shuō)的鍍鋅管，鍍鋅管的用途現(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?jiàn)A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(guò)高，嚴(yán)重危害人體的健康。六七十年代，國(guó)際上發(fā)達(dá)國(guó)家開(kāi)始開(kāi)發(fā)新型管材，并陸續(xù)禁用鍍鋅管。中國(guó)建設(shè)部等四部委也發(fā)文明確從二000年起禁用鍍鋅管，目前新建小區(qū)的冷水管已經(jīng)很少使用鍍鋅管了，有些小區(qū)的熱水管使用的是鍍鋅管。
