镀锌管，又被称为镀锌钢管，主要用于输送煤气、暖气，一般分为热镀锌和电镀锌两种。镀锌管表面的锌层可以避免腐蚀溶液直接接触钢基体，起到保护底材的作用。镀锌管作为工业生产的重要组成部分，在其表面涂装防腐漆，可延长镀锌管的使用寿命，一般选择环氧锌黄底漆。

Galvanized pipe, also known as galvanized steel pipe, is mainly used for conveying gas and heating, which is generally divided into hot-dip galvanizing and electro galvanizing. The zinc coating on the surface of galvanized pipe can prevent the corrosion solution from directly contacting with the steel substrate, which can protect the substrate. Galvanized pipe as an important part of industrial production, coating anticorrosive paint on its surface can extend the service life of galvanized pipe, generally choose epoxy zinc yellow primer.

无论是热镀锌还是电镀锌，镀锌管一旦经过镀锌处理，表面就会变得异常光滑。因此，一般的防腐漆根本无法粘附在其表面，即使附着上，也非常容易脱落。而环氧锌黄底漆可以说是镀锌管专用漆，该产品具有强的附着力，应对光滑的镀锌管表面毫无压力。

Whether it is hot-dip galvanizing or electro galvanizing, the surface of galvanized pipe will become extremely smooth once it is galvanized. Therefore, the general anti-corrosion paint simply can not adhere to its surface, even if attached, it is very easy to fall off. The epoxy zinc yellow primer can be said to be a special coating for galvanized pipe, which has strong adhesion and no pressure on the smooth surface of galvanized pipe.

很多人表示，镀锌管本就镀有一层锌，可以起到保护底材的作用，为什么还要多刷一层防腐漆呢？没错，镀锌的目的是为了防腐，但仅仅镀一层锌是远远不够的。尤其是对于腐蚀较为严重的工业场所来说，为镀锌管提供双重保护是很有必要的。

Many people say that the galvanized pipe is already coated with a layer of zinc, which can protect the substrate. Why should we brush an extra layer of anticorrosive paint? Yes, the purpose of galvanizing is to protect against corrosion, but only one layer of zinc is not enough. It is very necessary to provide double protection for galvanized pipe, especially for industrial places with serious corrosion.

环氧锌黄底漆不仅具有优异的防腐作用，还有比较好的装饰效果。该产品呈锌黄色，漆膜光亮饱满，呈现的视觉效果非常美观。如此，可以为对装饰效果要求较高的用户提供更加便利的选择。

Epoxy zinc yellow primer not only has excellent anti-corrosion effect, but also has good decorative effect. The product is zinc yellow, the film is bright and full, the visual effect is very beautiful. In this way, it can provide a more convenient choice for users who have higher requirements for decorative effect.
