What are the functions of the paint on the pole of the solar LED Outdoor Street lamp?
The key and importance of solar street lights as lighting equipment for public facilities and traffic roads is to ensure driving safety. The top paint on the solar light pole can ensure that the new solar street lights maintain their color in different environments and prevent rust. Ash content is an important factor in choosing the top coat of solar street light poles, so what kind of paint should be used for solar LED Outdoor Street lamp poles?
The commonly used anti-rust technology for solar street lampposts is hot-rolled steel plate + hot/cold galvanized + spraying + protective film:
After cold/hot galvanizing treatment, the solar LED roadway lighting pole will hardly rust (unless there is trachoma welded on the pole), so the only factor that affects the appearance of the street light is the exterior wall paint. After the solar light street pole is galvanized, the last layer of anti-corrosion coating will be sprayed.
Outdoor plastic powder or outdoor glitter plastic for spraying is better, but after actual use, it is found that the service life of outdoor plastic powder cannot reach 10 or even 20 years. Outdoor glitter plastic powder can be used outdoors for 3 years. After that, the luster of 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 on the surface at this time. Galvanizing is to prevent rust. Plastic sandblasting is for aesthetics, rust prevention and improved appearance. Then, adding a protective film is perfect. The outdoor powder has poor weather resistance.
If they can be packaged with super weather-resistant coatings, they can maintain their original color for a long time. However, this paint is not difficult to find. This is a "fluorocarbon coating". Fluorocarbon coatings have excellent corrosion resistance, maintenance-free, strong adhesion and good weather resistance. Fluorocarbon coatings can be applied to the plastic powder outer layer of solar street lamp poles to provide good protection. It is not a problem to maintain the surface gloss for more than ten years.
