在各种保护钢基体的涂镀方法中，热浸锌是优良的一种。它是在锌呈液体的状态下，经过了相当复杂的物理、化学作用之后， 在钢铁上不仅镀上较厚的纯锌层，而且还生成一种锌铁合金层。这种镀法，不仅具备了电镀锌的耐腐蚀特点，而且由于具有锌铁合金层。 还具有电镀锌所无法相比拟的强耐蚀性。因此这种镀法特别适用于各种强酸、碱雾气等强腐蚀环境中。 Among various coating methods for protect steel substrate, hot dip zinc is an excellent one.It is in the zinc in a liquid state, after quite complex physical, chemical action, on the steel not only coated with a thick pure zinc layer, but also to produce a zinc ferroalloy layer.This plating method not only has the corrosion resistance characteristics of electroplating zinc, but also due to the zinc ferroalloy layer.It also has a strong corrosion resistance incomparable to electrogalvanizing.Therefore, this plating method is particularly suitable for various strong acid, alkali fog and other strong corrosion environments.
