鍍鋅鋼管防腐鋅比鐵有還負(fù)的電極電位，當(dāng)鋅和鐵構(gòu)成微電池時(shí)，鋅為陽極，鐵為陰極，在遭到腐蝕時(shí)，鋅溶解而鐵不受危害。鍍鋅層有小的裂紋或損壞時(shí)，鋅將以獻(xiàn)身陽極的形式以免繼續(xù)裂紋或損壞處的鋼鐵生銹，這是鍍鋅層比其他涂鍍層不錯(cuò)的主要特點(diǎn)。熱鍍鋅鋼管浸鍍鋅時(shí)，鋅鐵合金層與鋼鐵基體、鋅層之間均為冶金結(jié)合，比漆類與鋼鐵的結(jié)合還結(jié)實(shí)。 </p> <p> 鍍鋅鋼管防腐鋅層對(duì)鋼鐵有屏蔽保護(hù)作用。鋅在大氣或其它環(huán)境下在鋼鐵基體外表形成屏蔽層。鋅的腐蝕過程增加了其形成屏蔽層的能力，這是因?yàn)殇\和空氣中的氧、二氧化碳、潮氣等反應(yīng)，生成一種抗腐蝕副產(chǎn)物堿式碳酸鋅膜。 </p> <p> 介于基體與純鋅層之間的鋅鐵合金層含鋅在90%，對(duì)鋼有與鋅近似的電化學(xué)保護(hù)作用;鍍層越厚，經(jīng)用年限也越長，經(jīng)用年限與厚度基本成正比。昆明Q345C鍍鋅方管廠家鍍鋅其防護(hù)作用更強(qiáng)，抗腐蝕能力強(qiáng)。</p><div style="width:100%;text-align: center;"><img

在鍍鋅20#無縫方距管[1]的第壹層焊縫時(shí)，盡量使鋅層熔化并使之汽化、蒸發(fā)而逸出焊縫，可很大程度上減少液體鋅留在焊縫中。在焊角焊縫時(shí)，同樣在第壹層盡量使鋅層熔化并使之汽化、蒸發(fā)而逸出焊縫，其方法是先將焊條端部向前移出約5~7mm左右，當(dāng)使鋅層熔化后再回到原來位置繼續(xù)向前施焊。再橫焊和立焊時(shí)，如選用短渣焊條如J427，咬邊傾向會(huì)很?。蝗绻捎们昂笸颠\(yùn)條技術(shù)，更可以得到無缺點(diǎn)的焊接質(zhì)量。 </p> <p> 焊接工藝控制鍍鋅20#無縫方距管的焊前準(zhǔn)備與一般的低碳鋼是相同的，需要注意的是要認(rèn)真處理好坡口尺寸和附近的鍍鋅層。為了焊透，坡口尺寸要適當(dāng)，一般60~65°，要留有一定的間隙，一般為1.5~2.5mm;為了減少鋅對(duì)焊縫的滲透，在焊之前，可將坡口內(nèi)的鍍鋅層清理以后再焊。在實(shí)際監(jiān)理工作中，采用了集中打坡口，不留鈍邊工藝進(jìn)行集中控制，兩層焊接工藝，減少了未焊透的可能性<span

鍍鋅方矩管生產(chǎn)工藝:生產(chǎn)過程中由于不進(jìn)行加熱，所以不存在熱軋矩管常出現(xiàn)的麻點(diǎn)和氧化鐵皮等缺點(diǎn)，表面質(zhì)量好、光潔度高。皮等缺點(diǎn)，表面質(zhì)量好、光潔度高。而且冷軋產(chǎn)品的尺寸精度高且冷軋產(chǎn)品的尺寸精度高，產(chǎn)品的性能和組織能滿足一些特殊的使用要求，和組織能滿足一些特殊的使用要求，如電磁性能、深沖性能等。電磁性能、深沖性能等。

電鍍鋅成本低，表面不是很光滑，其本身的耐腐蝕性比熱鍍鋅方管相差很多。冷鍍鋅工藝用于保護(hù)金屬防止腐蝕，為此利用了鋅填料的涂料.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明Q345C鍍鋅方管廠家,鍍鋅方管"

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不相同也就造就了它們很多不同的物理和化學(xué)性質(zhì)?？偟膩碚f它們?cè)趶?qiáng)度、韌性和機(jī)械性能方面都有很多的區(qū)別。熱鍍鋅方管熱鍍鋅方管：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(chǔ)上將方管置于熱鍍鋅池中經(jīng)過一系列化學(xué)反響有形成的一種方管。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(shè)備和資金很少，適合小型鍍鋅方管廠家的生產(chǎn)。但是從強(qiáng)度上來說這種鋼管的強(qiáng)度是遠(yuǎn)遠(yuǎn)低于無縫方管的。冷鍍鋅方管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(xué)原理來進(jìn)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。昆明Q345C鍍鋅方管廠家</p><p
