熱鍍鋅技術(shù)在鋼材中得以很好的利用。為什么它會(huì)受到那么多人的歡迎呢？接下來(lái)咱就隨冠翔來(lái)簡(jiǎn)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(duì)鋼鐵件防護(hù)要求越來(lái)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(wú)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(huì)形成新的膜層。當(dāng)鋅層破壞嚴(yán)重，危及到鐵基體時(shí)，鋅對(duì)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(shí)鋅作為陽(yáng)極被溶解，鐵作為陰極受到保護(hù)。顯然熱鍍鋅對(duì)基體金屬鐵的抗大氣腐蝕能力優(yōu)于電鍍鋅。
