熱鍍鋅方管用處很廣泛，主要運用幕墻、建筑、機械制造、太陽能發(fā)電支架、鋼結(jié)構(gòu)工程等，特別是在幕墻、建筑運用為廣泛。 </p> <p> 市場上一些商家用冷鍍鋅方管充肆熱鍍鋅方管，來牟取暴利。冷鍍鋅方管的防腐效果與熱鍍鋅方管的防腐效果相差甚遠。那么，我們在購買時應該怎么區(qū)分呢? 現(xiàn)在筆者教大家一下幾種點來區(qū)分熱鍍鋅方管與冷鍍鋅方管。 ,看外觀。冷鍍鋅方管外表比較光滑、明亮。熱鍍鋅方管外表與冷鍍鋅方管相比較稍微粗糙。第二,觀顏色。冷鍍鋅方管在與陽光呈一定角度下冷鍍鋅方管顏色泛黃綠色、青白色或者略顯七彩。熱鍍鋅方管在與陽光呈一定角度下顏色呈銀白色。第三,鋅層厚度。 </p></div><p><img

class="khcont">熱鍍鋅方管也稱熱浸鍍鋅方管，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，對鋼鐵件防護要求越來越高，熱鍍鋅方管需求量也不斷增加。[2] <br /> 防護性能<br /> 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200μm。熱鍍鋅方管覆蓋能力好，鍍層致密，無有機物夾雜。眾所周知，鋅的抗大氣腐蝕的機理有機械保護及電化學保護，在大氣腐蝕條件下鋅層表面有ZnO、Zn(OH)2及堿式碳酸鋅保護膜，一定程度上減緩鋅的腐蝕，這層保護膜(也稱白銹)受到破壞又會形成新的膜層。當鋅層破壞嚴重，危及到鐵基體時，鋅對基體產(chǎn)生電化學保護，鋅的標準電位-0.76V，鐵的標準電位-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。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。</div><p><img

鍍鋅方管從生產(chǎn)工藝上是分為熱鍍鋅方管和冷鍍鋅方管的。正是由于這兩種鍍鋅方管的加工不相同也就造就了它們很多不同的物理和化學性質(zhì)?？偟膩碚f它們在強度、韌性和機械性能方面都有很多的區(qū)別。 </p> <p> 熱鍍鋅方管：是在使用鋼板或者是鋼帶卷曲成型后焊接制成的方管，并在這種方管的基礎上將方管置于熱鍍鋅池中經(jīng)過一系列化學反應后又形成的一種方管。熱鍍鋅方管的生產(chǎn)工藝較為簡單，且生產(chǎn)效率是很高的，品種規(guī)格也多，這種方管所需要的設備和資金很少，適合小型鍍鋅方管廠家的生產(chǎn)。但是從強度上來說這種鋼管的強度是遠遠低于無縫方管的。<br /> 而冷鍍鋅方管是在所用的方管上利用冷鍍鋅的原理來使方管具有防腐蝕的性能。與熱鍍鋅不同冷鍍鋅涂料主要通過電化學原理來進行防腐，因此必須保證鋅粉與鋼材的充分接觸，產(chǎn)生電極電位差，所以鋼材表面處理很重要。 </p></div><p></p><div id="trvjtbn" class=imgtipsbox>點擊查看銳鼎鑫金屬材料銷售(義縣分公司)的<a
