What is the role of solar street light pole varnish?
The key and importance of solar street lights as public facilities and traffic road lighting equipment is to ensure traffic safety. The top coat on solar light poles ensures that the solar street lights maintain their color in different environments and prevent rusting. Ash content is essential in choosing the topcoat for solar light poles, so what kind of paint is used for solar street light poles? Here is what we share.
The standard anti-rust technology for solar street light poles is hot rolled steel + hot/cold galvanizing + spraying + protective film.
After cold/hot galvanizing treatment, solar street light poles will hardly rust (unless sand holes are welded on the pole), so the only factor affecting the appearance of street lights is the exterior coating. After galvanizing, the solar poles will be sprayed with a final anti-corrosion coating.
Spraying with outdoor plastic powder or outdoor glossy plastic is better. Still, after actual use, it is found that the service life of outdoor plastic powder cannot reach ten years or even 20 years, and outdoor glossy plastic powder can be used outdoors for three years. After that, the surface of the solar lamp post will gradually become darker, change color, and start to bloom. This is a perfect plastic powder. The poor-quality plastic powder can deteriorate entirely within one year. The most significant disadvantage of outdoor plastic powder is its poor resistance to aging.
Therefore, it is necessary to add a protective coating on the surface.
Galvanization is to prevent rusting. Plastic sandblasting is for aesthetics, rust prevention, and appearance improvement. Then, the protective film is added to protect such a perfect effect. Outdoor powders have poor weathering properties. If they could be packaged with super weathering paint, they could retain their original color for a long time. Fortunately, such stains are not difficult to find. It is a “fluorocarbon paint.” Fluorocarbon paint has excellent corrosion resistance, is maintenance-free, has strong adhesion, and has good weather resistance. Fluorocarbon coating can be applied to the outer layer of plastic powder of solar street light poles to provide reasonable protection. Keeping the surface gloss for more than ten years is not a problem.
