鋼管鍍鋅前要經過鍍前處理酸洗、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。當酸液濃度下降至100g/L時應補充或更換，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鍍效果，昆明鍍鋅方管銷售廠家，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烘干，烘干溫度100~130度，時間一般為6~10分鐘。

</span><span style="font-size:14px;"> 3、鍍鋅層重量：根據需方要求，鍍鋅鋼管可作鋅層重量測定，其平均值應不小于500g/平方米，其中任何試樣不得小于480g/平方米。</span> 昆明鍍鋅方管銷售廠家</p><p
