鍍鋅鋼管的鋅鍍層的使用溫度不得超過2500C,在此溫度上鋅結(jié)晶組織變形，發(fā)脆，耐蝕性下降。有耐蝕，耐熱要求的零件宜用Zn-Ni合金層。鍍鋅電解液可分為堿性和弱酸性兩大類，國內(nèi)外常用的有無氰鋅酸鹽鍍鋅，**鍍鋅，銨鹽鍍鋅，氯化物鍍鋅，昆明官渡區(qū)國標(biāo)鍍鋅圓管哪家好，硫酸鹽鍍鋅等，昆明官渡區(qū)國標(biāo)鍍鋅圓管哪家好。就國內(nèi)而言，無氰鋅酸鹽鍍鋅仍是主流。近年來由于鍍鋅添加劑的性能的改進(jìn)提高，氯化物鍍鋅和低氰光亮鍍鋅發(fā)展較快，昆明官渡區(qū)國標(biāo)鍍鋅圓管哪家好，而銨鹽鍍鋅在繼續(xù)下降。

熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)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(jìn)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(qiáng)，使用壽命長等優(yōu)點(diǎn)。 </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(chǎn)廠家，為了保證質(zhì)量，大多不采用電鍍鋅（冷鍍）。只有那些規(guī)模小、設(shè)備陳舊的小企業(yè)采用電鍍鋅，當(dāng)然他們的價(jià)格也相對便宜一些。目前建設(shè)部已正式下文，淘汰技術(shù)落后的冷鍍鋅管，今后不準(zhǔn)用冷鍍鋅管作水、煤氣管。
