济南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。

The galvanized pipe in Ji'nan is to make molten metal react with the iron substrate to produce alloy layer, so that the substrate and the two layers of the coating are combined. The hot dip galvanizing is first to wash the steel tube, in order to remove the iron oxide on the surface of the steel tube. After pickling, it is cleaned by the solution of ammonium chloride or zinc chloride or ammonium chloride and zinc chloride in the mixed solution tank, and then sent into the hot dip bath.

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。

There is complex physical and chemical reaction between the steel tube matrix and the molten bath, forming a corrosion resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel tube substrate. Therefore, its corrosion resistance is strong.

锌层是电镀层,锌层与钢管基体独立分层。锌层较薄,锌层简单附着在钢管基体上,容易脱落。故其耐腐蚀性能差。在新建住宅中,禁止使用冷镀锌钢管作为给水管。

The zinc layer is an electroplating layer, and the zinc layer is separately separated from the steel tube substrate. The zinc layer is thin, and the zinc layer is simply attached to the steel tube substrate, so it is easy to fall off. Therefore, its corrosion resistance is poor. In new buildings, cold galvanized steel pipes are not allowed to be used as water pipes.
