熱鍍鋅技術(shù)在鋼材中得以很好的利用。為什么它會受到那么多人的歡迎呢？接下來咱就隨冠翔來簡單了解一下熱鍍鋅的技術(shù)的原理。 </p> <p> 熱鍍鋅也稱熱浸鍍鋅，是鋼鐵構(gòu)件浸入熔融的鋅液中獲得金屬覆蓋層的一種方法。隨高壓輸電、交通、通訊事業(yè)迅速發(fā)展，對鋼鐵件防護(hù)要求越來越高，熱鍍鋅需求量也不斷增加。 </p> <p> 熱鍍鋅具有很強(qiáng)的防護(hù)性能 </p> <p> 通常電鍍鋅層厚度5～15μm，而熱鍍鋅層一般在35μm以上，甚至高達(dá)200μm。熱鍍鋅覆蓋能力好，鍍層致密，無有機(jī)物夾雜。眾所周知，鋅的抗大氣腐蝕的機(jī)理有機(jī)械保護(hù)及電化學(xué)保護(hù)，在大氣腐蝕條件下鋅層表面有ZnO、Zn(OH)2及堿式碳酸鋅保護(hù)膜，一定程度上減緩鋅的腐蝕，這層保護(hù)膜(也稱白銹)受到破壞又會形成新的膜層。當(dāng)鋅層破壞嚴(yán)重，危及到鐵基體時，鋅對基體產(chǎn)生電化學(xué)保護(hù)，鋅的標(biāo)準(zhǔn)電位-0.76V，鐵的標(biāo)準(zhǔn)電位-0.44V，鋅與鐵形成微電池時鋅作為陽極被溶解，鐵作為陰極受到保護(hù)。顯然熱鍍鋅對基體金屬鐵的抗大氣腐蝕能力優(yōu)于電鍍鋅。

1. 無縫鋼管按生產(chǎn)方法可分為：熱軋無縫管、冷拔管、精密鋼管、熱擴(kuò)管、冷旋壓管和擠壓管等。 </p> <p> 無縫鋼管用優(yōu)異碳素鋼或合金鋼制成，有熱軋、冷軋（拔）之分。 </p> <p> 2.焊接鋼管因其焊接工藝不同而分為爐焊管、電焊（電阻焊）管和自動電弧焊管，因其焊接形式的不同分為直縫焊管和螺旋焊管兩種，因其端部形狀又分為圓形焊管和異型（方、扁等）焊管。 </p> <p> 焊接鋼管是由卷成管形的鋼板以對縫或螺旋縫焊接而成，在制造方法上，又分為低壓流體輸送用焊接鋼管、螺旋縫電焊鋼管、直接卷焊鋼管、電焊管等。無縫鋼管可用于各種行業(yè)的液體氣壓管道和氣體管道等。焊接管道可用于輸水管道、煤氣管道、暖氣管道、電器管道等。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。</p><div

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)。 </p> <p> 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。 </p> <p>
