style="text-indent:25px">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。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。昆明鍍鋅圓管哪家好鍍鋅管鍍銅屬于連續(xù)電鍍，但電鍍設(shè)備不同。</p><div
