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。鍍鋅方管有熱鍍鋅方管和電鍍鋅方管兩大類。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?，F(xiàn)生產(chǎn)中主要采用干法和氧化還原法，其特點見表。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)上有一定的復雜性，但對單面鍍層，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
