而冷鍍鋅方管是在所用的方管上利用冷鍍鋅的原理來(lái)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(guò)電化學(xué)原理來(lái)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。 </p> <p> 方管生產(chǎn)廠家有熱鍍鋅方管和電鍍鋅方管兩大類(lèi)，昆明鍍鋅方管生產(chǎn)廠家，昆明鍍鋅方管生產(chǎn)廠家。熱鍍鋅方管有濕法、干法、鉛鋅法、氧化還原法等。不同熱鍍鋅方法的主要區(qū)別在鋼管酸浸清洗后，用什么方法活化管體表面提高鍍鋅質(zhì)量，昆明鍍鋅方管生產(chǎn)廠家。現(xiàn)生產(chǎn)中主要采用干法和氧化還原法，其特點(diǎn)見(jiàn)表。電鍍鋅的鋅層表面十分光滑致密、組織均勻；具有良好的力學(xué)性能和抗腐蝕能力;鋅耗比熱鍍鋅低60%～75%。電鍍鋅在技術(shù)上有一定的復(fù)雜性，但對(duì)單面鍍層，內(nèi)外表面鍍層厚度不同的雙面鍍層，以及薄壁管鍍鋅等皆須采用此法。

1.防腐功能：因?yàn)樗怯蓪こ５暮附臃焦?在它的表面進(jìn)行熱鍍鋅或許冷鍍鋅的工藝進(jìn)行處理的,不妨預(yù)防和空氣直接接觸,如此的話(huà)發(fā)生氧化的可能性就會(huì)降低很多,耐腐蝕功能就不妨升高很多. </p> <p> 2.強(qiáng)度特點(diǎn)：鍍鋅方管是始末多種工藝進(jìn)行加工制作的管材,擁有其余的管材不具備的輕度,從強(qiáng)度上面而言,遠(yuǎn)遠(yuǎn)高于無(wú)縫鋼管,所以運(yùn)用在建筑業(yè)和產(chǎn)業(yè)上面是對(duì)照不錯(cuò)的. </p> <p> 鍍鋅板較大的特點(diǎn)肯定即是它的外觀,通常而言管材都是圓形,可是鍍鋅方管是方形的,運(yùn)用的場(chǎng)面愈加的獨(dú)特,是別的管材無(wú)法替代的。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明鍍鋅方管生產(chǎn)廠家" src="http://tyunfile.71360.com/UploadFile/ynmaoxuan/637203121509306640/893429.jpg"></div><p> <span style="font-size:14px;"> 鋼材力學(xué)性能是保證鋼材**終使用性能（機(jī)械性能）的重要指標(biāo)，它取決于鋼的化學(xué)成分和熱處理制度。在鋼管標(biāo)準(zhǔn)中，根據(jù)不同的使用要求，規(guī)定了拉伸性能（抗拉強(qiáng)度、屈服強(qiáng)度或屈服點(diǎn)、伸長(zhǎng)率）以及硬度、韌性指標(biāo)，還有用戶(hù)要求的高、低溫性能等。</span> </p> <p> <span style="font-size:14px;"> 1、鍍鋅層的均勻性：鋼管試樣在硫酸銅溶液中連續(xù)浸漬5次不得變紅（鍍銅色）。</span> </p> <p> <span style="font-size:14px;"> 2、表面質(zhì)量：鍍鋅鋼管的表面應(yīng)有完整的鍍鋅層，不得有未鍍上的黑斑和氣泡存在，允許有不大的粗糙面和局部鋅瘤存在。</span> </p> <p> <span style="font-size:14px;"> </span><span style="font-size:14px;"> 3、鍍鋅層重量：根據(jù)需方要求，鍍鋅鋼管可作鋅層重量測(cè)定，其平均值應(yīng)不小于500g/平方米，其中任何試樣不得小于480g/平方米。</span> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
