Hot dip galvanizing is a coating process that covers metal zinc on the surface of the substrate and is often used to protect metal materials from corrosion and oxidation. The following will introduce the characteristics and advantages of hot dip galvanizing.
1. Corrosion resistance: hot dip galvanizing can prevent metal materials from being damaged by oxidation and corrosion. Zinc has a wide range of corrosion resistance and can form a water-insoluble protective layer in the presence of oxygen and water to protect the substrate from the erosion of the external environment.
2. Uniform and stable coating: hot dip galvanizing can form a uniform, dense and high adhesion zinc layer on the surface of the substrate. This coating is not easy to flake or drop, and can protect the substrate stably.
3. Good adaptability of coating: hot dip galvanizing is suitable for various metal materials, such as iron, steel, aluminum and so on. Not only can be plated on flat materials, but also can be plated on complex shape of the workpiece, such as wire, pipe and so on.
4. Significant aesthetic effect: hot dip galvanizing can bring bright and glossy surface to metal materials, making it more beautiful and increasing its value. Therefore, hot dip galvanizing is often used on outdoor equipment and building structures for landscape decoration and corrosion protection.
5. The thickness of the coating is highly controllable: by adjusting the process parameters of hot dip galvanizing, the thickness of the zinc layer can be controlled to meet the requirements of different applications. This makes the hot-dip galvanizing process more flexible and adaptable.
6. Hot-dip galvanized wire has self-healing properties: when the metal is scratched or damaged, the zinc will spontaneously oxidize to produce zinc oxide, and form a dense oxide layer, which plays the role of repair and protection, and prevents the zinc lower metal from being exposed to the environment.
7. Easy detection: Compared with other anti-corrosion coatings, hot-dip galvanizing has the advantage of easy detection. The quality and adhesion of hot-dip galvanized coatings can be tested by means of appearance inspection, electrochemical analysis or thermoluminescence.
8. The coating and the substrate have a good metallurgical combination: hot dip galvanizing is a metallurgical connection method, the coating and the substrate formed a metallurgical combination, with high adhesion and resistance to spalling.
9. Extend the service life: By providing protection for metal materials, hot-dip galvanizing can extend the service life of metal materials and reduce the cost of maintenance and replacement.
