鍍鋅圓管其實也會生銹，只是鍍鋅層首先被氧化保護了鋼管不生銹，其使用壽命更長。鍍鉻的鉻層自然條件下不會與空氣中的氧、二氧化碳、水反應(yīng)，也不被弱酸、堿腐蝕，其防銹效果當(dāng)然更好些。如果鍍鋅層夠厚的話按理論是不會生銹的，因為鋼管的表面被一層金屬鋅包裹，與空氣隔離開，所以鋼管是不會生銹的。 </p> <p> 這和安裝的環(huán)境也有關(guān)，環(huán)境如有潮濕、長時間淋雨，慢慢的鍍鋅圓管就會出現(xiàn)氧化、斑點、到就會被腐蝕生銹，如果想要使用壽命長久一些，保持較干燥、盡量選擇室內(nèi)施工，這樣的話使用年期大概在5-10年甚至更久(但不包括一些市面上的劣質(zhì)品)。鋼管鍍鋅以后，表面覆蓋了一層鋅的涂層，使鋼管和大氣隔了開來，避免了大氣對鋼管的直接接觸和銹蝕，得到了保護。而鋅在鋼管表面的涂層，由于鋅的化學(xué)活性比較強，常溫下在空氣中就會形成薄而致密的一層碳酸鋅，保護鋅自身不會繼續(xù)被氧化。昆明官渡區(qū)6分鍍鋅圓管廠家電話鍍鋅圓管廠家現(xiàn)貨供應(yīng)，云南贛僑貿(mào)易供應(yīng)。</p><div

熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進行酸洗，為了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行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強，使用壽命長等優(yōu)點。 </p> <p> 冷鍍鋅管 </p> <p> 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）。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。目前建設(shè)部已正式下文，淘汰技術(shù)落后的冷鍍鋅管，今后不準用冷鍍鋅管作水、煤氣管。
