鍍鋅圓管工藝流程：圓管酸洗→水洗→浸助鍍溶劑→烘干預熱→掛鍍→冷卻→鈍化→清洗→打磨→熱鍍鋅完工。鍍鋅圓管的鍍鋅層厚度均勻，可達30-50um，可靠性好，鍍鋅層與鋼材間是冶金結合，成為鋼表面的一部份，因此鍍鋅圓管的鍍層持久性較為可靠。 </p> <p> 鍍鋅圓管也叫熱浸鍍鋅鍍鋅圓管或熱浸鋅鍍鋅圓管。是將除銹后的鍍鋅圓管浸入500℃左右融化的鋅液中，使鍍鋅圓管表面附著鋅層，從而起到防腐的目的，適用于各種強酸、堿霧氣等強腐蝕環(huán)境中。 </p> <p>

</p>鍍鋅圓管有著很好的性能優(yōu)勢，能夠在工業(yè)建設中發(fā)揮重要作用。一般在進行工程建設的時候都會選擇***產品來保障質量。對此就需要遵守這樣幾點選購標準： <p> 1、鍍鋅圓管選材需要產看材料構成，簡單的來說就是通過成分構成來看其比率，在同類型鋼管中有哪些優(yōu)勢性能，這樣在進行施工建設的時候更加幫助。 </p> <p> 2、在選擇鍍鋅圓管的時候要善于比較，從尺寸、型號、價格等方面來成分了解，根據(jù)作業(yè)環(huán)境來選擇相當有優(yōu)勢的鍍鋅圓管。 </p> <p> 2、很多人在進行建材選料的時候，通常會因為自身經驗導致很多錯誤，這個時候就有待注意。***鍍鋅圓管是要與施工建設需求相溫和的，在不同的工作領域，對于鍍鋅圓管的需求也不一樣，這個時候就需要嚴格區(qū)分開來。 </p> <p>

熱鍍鋅管是使熔融金屬與鐵基體反應而產生合金層，從而使基體和鍍層二者相結合。熱鍍鋅是先將鋼管進行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強，使用壽命長等優(yōu)點。 </p> <p> 冷鍍鋅管 </p> <p> 冷鍍鋅就是電鍍鋅，鍍鋅量很少，只有10－50g/m2，其本身的耐腐蝕性比熱鍍鋅管相差很多。正規(guī)的鍍鋅管生產廠家，為了保證質量，大多不采用電鍍鋅（冷鍍）。只有那些規(guī)模小、設備陳舊的小企業(yè)采用電鍍鋅，當然他們的價格也相對便宜一些。目前建設部已正式下文，淘汰技術落后的冷鍍鋅管，今后不準用冷鍍鋅管作水、煤氣管。 </p> <p> <br />
