镀锌角钢是怎么进行镀锌的呢?

钢材本身就是一种非常优质的产品,这主要是因为镀锌角钢没有办法自然应对人类加诸在环境中的种种污染,因此它需要一层保护膜,用来保护里面的材料,镀锌角钢的镀锌层是锌在高温液态下,分三个步骤形成的:

Steel itself is a very high quality product, mainly because the galvanized angle steel does not naturally respond to all kinds of pollution in the environment, so it needs a layer of protective film to protect the material. The galvanized layer of the galvanized angle steel is formed by three steps of zinc in the high temperature liquid.

1、将除锈后的槽钢浸入440~460℃左右融化的锌液中,铁基表面被锌液溶解形成锌—铁合金相层;

  1. The channel steel after derusting is immersed in molten zinc at about 440~460 degrees, and the iron base surface is dissolved by zinc solution to form a zinc ferroalloy phase.

2、合金层中的锌离子进一步向基体扩散形成锌铁互溶层;

2. The zinc ions in the alloy layer further diffuse to the matrix to form a zinc iron miscible layer.

3、合金层表面包络着锌层。

3, the surface of the alloy layer is covered with zinc layer.

济南镀锌管在镀锌角钢的涂镀方法中,热浸锌是非常优良的一种。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。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。

Hot dip galvanizing is a very good method for the galvanizing of galvanized steel in Ji'nan. It is in the state of zinc liquid, after a fairly complex physical and chemical action, it is not only plated with a thick zinc layer on the steel, but also a zinc iron alloy layer. It has a zinc - iron alloy layer. It also has a strong corrosion resistance which can not be compared with that of zinc plating. Therefore, this plating method is especially suitable for strong corrosive environments such as strong acids and alkali fogs.
