style="text-indent:25px">熱鍍鋅管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(zhǎng)等優(yōu)點(diǎn)。鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。</p><p

硫酸鹽鍍鋅的比較大優(yōu)點(diǎn)是電流效率高達(dá)****，沉積速度快，是其他鍍鋅工藝無(wú)法比擬的。由于涂層結(jié)晶度差、分散性差、鍍深能力差，只適用于幾何形狀簡(jiǎn)單的管材和線材的鍍覆。硫酸鹽鍍鋅鐵合金工藝優(yōu)化了傳統(tǒng)的硫酸鹽鍍鋅工藝。只有主鹽硫酸鋅被保留，其余成分被丟棄。在新工藝配方中加入適量鐵鹽，使原來(lái)的單一金屬鍍層形成鋅鐵合金鍍層。該工藝的重組不僅發(fā)揮了原工藝電流效率高、沉積速度快的優(yōu)點(diǎn)，而且很大程度上提高了分散性和深鍍能力。過去，復(fù)雜零件不能電鍍，但現(xiàn)在簡(jiǎn)單和復(fù)雜零件都可以電鍍，保護(hù)性能比單一金屬高3-5倍。生產(chǎn)實(shí)踐表明，涂層晶粒比原涂層晶粒更細(xì)、更亮，沉積速度更快。涂層厚度可在2-3分鐘內(nèi)滿足要求。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管相差很多。昆明Q355B熱鍍鋅管報(bào)價(jià)</p><p
