What are the functions of the paint on the solar street light pole?

The key and importance of solar street lights as public facilities and traffic road lighting equipment is to ensure driving safety. The top coat on the solar light pole can ensure that the solar street light maintains its color in different environments and prevents it from rusting. The ash content is an important factor in choosing the finish paint of solar light poles, so what kind of coating is used for solar light poles?

The commonly used anti-rust technology for solar street light posts is hot-rolled steel plate + hot/cold galvanizing + spraying + protective film:

After cold/hot galvanizing treatment, the solar street light pole will hardly rust (unless there are trachoma welded on the light pole), so the only factor that affects the appearance of the street light is the exterior wall paint. After the solar light pole is galvanized, the last layer of anti-corrosion coating will be sprayed.

It is better to use outdoor plastic powder or outdoor bright powder plastic for spraying, but after actual use, it is found that the service life of outdoor plastic powder cannot reach 10 or even 20 years, and outdoor bright powder plastic powder can be used outdoors for 3 years. After that, the luster on the surface of the solar lamp post will gradually darken, then change color and start to color. This is a good plastic powder. Inferior plastic powder can be completely replaced within one year. The biggest disadvantage of outdoor plastic powder is its poor aging resistance.

Therefore, it is necessary to add a protective film to the surface at this time. Galvanized to prevent rust. Plastic sandblasting is for aesthetics, rust prevention and improved appearance. Then, adding a protective film is perfect. Outdoor powder has poor weather resistance. If they can be packaged with super weather-resistant paint, they can keep their original color for a long time. However, this paint isn’t hard to find. This is a “fluorocarbon coating”. Fluorocarbon coatings have excellent corrosion resistance, maintenance-free, strong adhesion, and good weather resistance. Fluorocarbon coating can be applied to the plastic powder outer layer of the solar street light pole to provide good protection effect. It is not a problem to maintain the surface gloss for more than ten years.
