一般來說，鍍鋅鋼在低碳鋼外面涂有一層鋅，鍍鋅層一般為20um厚。鋅的熔點(diǎn)為419℃，沸點(diǎn)約為908℃。在焊接中，鋅熔化成液體，漂浮在熔池表面或焊縫根部。鋅在鐵中有很大的固體溶解度。液態(tài)鋅將沿著晶界腐蝕焊接金屬，低熔點(diǎn)鋅將形成“液態(tài)金屬脆化”。同時(shí)，鋅和鐵會(huì)在金屬間形成脆性化合物。這些脆性相會(huì)降低焊接金屬的塑性，并在拉伸應(yīng)力下導(dǎo)致裂紋。昆明Q355B熱鍍鋅管規(guī)格必須小心處理凹槽尺寸和附近的鍍鋅層。</p><div

鍍鋅管有什么用? </p> <p> 1、鍍鋅管分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強(qiáng)，使用壽命長等優(yōu)點(diǎn)。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。 </p> <p> 2、鍍鋅管的用途：現(xiàn)在煤氣、結(jié)構(gòu)由鋅，形成致密的四元結(jié)晶體，此結(jié)晶體在鋼板上形成一層屏障，因而有效的防止腐蝕因子穿透。耐腐蝕性來自鋅的障礙層保護(hù)功能強(qiáng)。當(dāng)鋅在切邊、刮痕及鍍層擦傷部份作**保護(hù)時(shí)，鋅便形成不能溶解的氧化物層，發(fā)揮屏障保護(hù)功能。 </p><p
