Galvanized steel

The hot-dip galvanized tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickl

Galvanized steel

热镀锌管是使熔融金属与铁基体反应而产生合金层，从而使基体和镀层二者相结合。热镀锌是先将钢管进行酸洗，为了去除钢管表面的氧化铁，酸洗后，通过氯化铵或氯化锌水溶液或氯化铵和氯化锌混合水溶液槽中进行清洗，然后送入热浸镀槽中。热镀锌具有镀层均匀，附着力强，使用寿命长等优点。钢管基体与熔融的镀液发生复杂的物理、化学反应，形成耐腐蚀的结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体。故其耐腐蚀能力强。
