The commonly used anti-rust process for the poles of street lamps is hot/cold galvanized spraying. After qualified galvanized spraying treatment, the theoretical life of the light pole is 15-20 years, that is to say, the surface paint of the solar street light will not fade or rust. Can this effect really be achieved in use?

After cold/hot-dip galvanizing, the street light pole will hardly rust (except for trachoma during welding), so the factor that affects the beauty of solar street lights is the exterior wall paint. A kind of anti-corrosion coating process after galvanizing the street light pole - spraying. The plastic powder used in spraying is outdoor plastic powder. Outdoor plastic powder has the characteristics of high hardness and strong adhesion. Although the appearance and anti-corrosion effect of the lamp post are further improved after spraying, it is found that the service life of the plastic powder cannot reach 10 years after actual use, let alone 15-202000 years. Take better outdoor high-gloss plastic powder as an example. After spraying the plastic, the surface of the light pole is bright and smooth, but after three years of outdoor use, the gloss on the surface of the light pole will gradually darken, and then begin to discolor and peel off the paint. This is a good plastic powder. Poor quality plastic powder can change in just one year. The disadvantage of outdoor plastic powder is poor aging resistance.

There is a way to extend the life of the solar street light surface paint so that the original color can be maintained for a long time without changing the color or powder. If galvanizing is for rust prevention, plastic spraying is for beauty. If the rust-proof effect is achieved, then the aesthetics are good, then add a protective film. The weather resistance of outdoor powders is poor. If it can be packaged with super weather-resistant exterior wall paint, it can keep the original color for a long time, but the exterior paint is not difficult to find, it is a fluorocarbon paint, fluorocarbon paint has excellent corrosion performance, maintenance-free, strong adhesion, long weather resistance, fluorocarbon paint The paint can play a very good protective role, so that the gloss of the outer paint on the surface is not a problem for more than ten years.
