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(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。

鋼管鍍鋅前要經(jīng)過鍍前處理酸洗、清洗、沖洗、浸涂溶劑、烘干。焊管由行車吊至酸洗槽中進行酸洗(每吊2噸左右)。26%左右的鹽酸溶液進行酸洗，為了防止過分酸洗和酸霧揮發(fā)，在酸洗液中添加0.5~1.0g/L的緩蝕劑和抑霧劑，常溫進行酸洗，酸洗時間一般為30~60分鐘，為使鋼管能均勻酸洗，在酸洗過程中采用吊車將鋼管起吊2~3次，以提高酸洗效果。當(dāng)酸液濃度下降至100g/L時應(yīng)補充或更換，含鐵量達到220~260g/L作為廢酸排放。酸洗后的鋼管由行車吊至清洗槽進行清洗以去除酸洗后積聚在鋼管表面的殘酸和鐵鹽，然后吊至沖洗臺架用0.7~0.8Mpa的清水沖洗，待水滴干后，將鋼管吊至溶劑槽中浸涂，浸蘸時間約一分鐘，溶劑采用600~650g/L氯化鋅和80~100g/L氯化銨以及1~2g/L的OP-10表面活性劑。為提高鋼管的溶劑中預(yù)鍍效果，溶劑始終保持弱堿性，然后由行車吊至干燥爐臺架進入干燥爐內(nèi)烘干，烘干溫度100~130度，時間一般為6~10分鐘。 </p> <p> 硫酸鹽鍍鋅的優(yōu)化硫酸鹽鍍鋅管比較大優(yōu)點是電流效率高達****，沉積速率快，這是其他鍍鋅工藝無可比擬的 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明鍍鋅方管便宜"
