鍍鋅管，也稱為鍍鋅鋼管，分為熱浸鍍鋅和電鍍鋅。熱浸鍍鋅層厚，涂層均勻，附著力強(qiáng)，使用壽命長。電鍍成本低，表面不光滑，耐腐蝕性比熱浸鍍鋅管差。鍍鋅鋼管：熱鍍鋅鋼管鋼管基板與熔融電鍍液復(fù)合物理、發(fā)生化學(xué)反應(yīng)，形成致密的鋅鐵合金層耐腐蝕結(jié)構(gòu)。合金層與純鋅層、鋼管襯底集成在一起。因此，其耐腐蝕性強(qiáng)。<br /> 鍍鋅鋼管：冷鍍鋅鋼管鋅層是電鍍層，鋅層與鋼管基板分開分層。鋅層很薄，鋅層簡單地附著在鋼管基板上，很容易脫落。因此，其耐腐蝕性差。在新家中，禁止使用冷鍍鋅鋼管作為供水管。</pstyle="margin:0px;padding:0px;color:#666666;text-transform:none;text-indent:0px;letter-spacing:normal;font-family:微軟雅黑;font-size:14px;font-style:normal;font-weight:400;word-spacing:0px;white-space:normal;orphans:2;widows:2;background-color:#ffffff;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;">
