</p> <p> 一般情況下，殘次的鍍鋅方管是呈現(xiàn)一個折疊狀態(tài)的，而這種折疊狀態(tài)的鍍鋅方管的外表，昆明鍍鋅方管批發(fā)，是構(gòu)成了這種折線的主要原因，這種缺點，往往就是貫穿著整個產(chǎn)物的縱向，而發(fā)生折疊的緣由，就可能是由于一些達不到要求的生產(chǎn)廠家，過于追求高的效率，而這樣在壓下量偏大的時候，就會產(chǎn)生這種折疊，而如果使用這種折疊的鍍鋅方管，進行折彎之后可能會出現(xiàn)開裂，這樣的鋼材強度并不大。 </p> <p> 而一些殘次的鍍鋅方管，在表面上面還會出現(xiàn)麻面的現(xiàn)象，而這些麻面，昆明鍍鋅方管批發(fā)，是可能因為生產(chǎn)廠家，所使用的生產(chǎn)設(shè)備的表面，不規(guī)則和高低不平而引起的，這樣因為殘次的鍍鋅方管，往往會讓生產(chǎn)設(shè)備超支，所以外表就會出現(xiàn)麻面的現(xiàn)象。而往往質(zhì)量不是很好的鍍鋅方管，昆明鍍鋅方管批發(fā)，還是會容易產(chǎn)生結(jié)疤，因為一般質(zhì)量不高的鍍鋅方管，所生產(chǎn)的原材料都大多不是很均勻，其中所含的雜志比較高。并且低質(zhì)量的的生產(chǎn)設(shè)備，也大多非常的簡陋，很容易就會造成粘鋼等問題，這樣就會在生產(chǎn)出來的鍍鋅方管，上面出現(xiàn)***。

(2)硫是鋼中的有害雜質(zhì)。硫含量高的鋼在高溫高壓下加工容易產(chǎn)生裂紋，通常稱為熱脆性。 </p> <p> (3)磷能使鋼的塑性和韌性明顯降低，特別是在低溫下，這種現(xiàn)象稱為冷脆。在質(zhì)量鋼中，應(yīng)嚴(yán)格控制硫和磷。另一方面，低碳鋼中硫、磷含量高，易切削，有利于提高鋼的機械加工性能。 </p> <p> (4)錳;能提高鋼的強度，能削弱和消除硫的不利影響，提高鋼的淬透性。高錳含量的高合金鋼(高錳鋼)具有良好的耐磨性和其他物理性能。 </p> <p> (5)硅;它能提高鋼的硬度，但塑性和韌性降低。電工用鋼中含有一定量的硅，可以改善其軟磁性能。 </p> <p> (6)鎢;能提高鋼的紅硬度和熱強度，提高鋼的耐磨性。 </p> <p> (7)鉻，可以提高鋼的淬透性和耐磨性，提高鋼的耐腐蝕性和抗氧化性。 </p> <p> 為了提高耐腐蝕性，對普通鋼管(黑管)進行鍍鋅處理。鍍鋅鋼管分為熱鍍鋅和電工鋼鍍鋅。熱鍍鋅層厚，鍍鋅成本低，可選用鍍鋅鋼管。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明鍍鋅方管批發(fā)" src="http://tyunfile.71360.com/UploadFile/ynmaoxuan/637203121507939453/987274.jpg"></div><p> 鍍鋅方管的分類 </p> <p> 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它們在強度、韌性和機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)。但是從強度上來說這種鋼管的強度是遠遠低于無縫方管的。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。
