What is the purpose of the surface paint on solar lamp posts? The importance of solar street lamps as public facilities and traffic road lighting equipment lies in ensuring driving safety. The surface paint on solar lamp posts ensures that the lamps maintain their color in different environments and prevents rust. The ash content is an important factor in choosing the surface paint for solar lamp posts. What type of coating is used for outdoor solar lamp posts? Century Sunshine will share insights.
The most commonly used rust-proof technology for solar street lamp posts is hot-rolled steel plates + hot/cold galvanizing + spraying + protective film.
After cold/hot galvanization, solar street lamp posts are almost impervious to rust, unless there are welds with defects. Therefore, the only factor affecting the appearance of the lamp posts is the exterior coating. After galvanization, the last layer of anti-corrosion coating is sprayed onto the lamp post.
It is better to use outdoor plastic powders or outdoor bright powders for spraying, but practical usage shows that the lifespan of outdoor plastic powder may not reach ten or even twenty years; outdoor bright powder plastic can be used for three years outdoors. After that, the surface gloss of the solar lamp post will gradually darken, change color, and begin to fade. Good quality plastic powder can last longer, while poor-quality plastic powder may require complete replacement within a year. The main disadvantage of outdoor plastic powder is its poor aging resistance.
Therefore, it is necessary to add a protective film to the surface at this point. Galvanization is done to prevent rust. Plastic spraying is intended for aesthetics, rust prevention, and improving appearance. Adding a protective film then completes the process. Outdoor powders tend to have poor weather resistance. If they can be coated with super weather-resistant paint, they can maintain their original color for an extended period. However, this type of paint is not difficult to find. A “fluorocarbon coating” provides excellent corrosion resistance, maintenance-free properties, strong adhesion, and good weather resistance. Fluorocarbon coatings can be applied to the outer layer of the plastic powder on solar street lamp posts, offering good protective effects and maintaining surface gloss for over ten years without issues.
The above is about the usage of surface paints on solar courtyard lamp posts. The safety and reliability of solar street lamps are very important. The maintainability of solar street lamps is also crucial. In various environments, such as fog, rain, and pollution, solar street lamps must meet the safety requirements for road lighting.
