Benefits of using top coat

The most commonly used anti-rust process used by street lamp manufacturers is hot-rolled steel plate + hot/cold galvanized + plastic spraying. The theoretical life of the lamp pole after qualified galvanizing and plastic spraying is 15-20 years, that is to say at least 15 years The surface paint of the street lamp will not fade or rust. The theory is the theory after all. Can this effect be achieved in actual use? The street lamp poles of street lamp manufacturers will hardly rust after being cold/hot galvanized (except for trachoma during lamp pole welding), then the only factor that affects the appearance of the street lamp is the exterior paint, and the street lamp pole is galvanized After that, the last anti-corrosion coating process will be carried out-plastic 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 light pole after spraying is in The appearance and anti-corrosion effect have been further improved, but after actual use, it is found that the service life of plastic powder cannot reach 10 years, let alone 15-20 years. Take a better outdoor high-gloss plastic powder as an example. The surface of the light pole after spraying is bright and smooth, but after three years of outdoor use, the luster of the light pole surface will gradually dim and then begin to change color and peel off the paint. This is a good plastic powder, and poor quality plastic powder will change completely within a year. The biggest disadvantage of outdoor plastic powder is its poor aging resistance. There is a way to extend the life of street lamp surface paint, so that it can maintain the original color for a long time without changing color and chalking. If galvanizing is for rust prevention, then plastic spraying is for beauty. If rust prevention is achieved, the beauty is good, then adding a layer of protective film will be perfect. The weather resistance of outdoor powder is very poor. If it can be encapsulated with an outer paint with super weather resistance, it can keep its original color for a long time. However, this kind of outer paint is not difficult to find, it is 'fluorocarbon paint' , Fluorocarbon paint has excellent anti-corrosion performance, maintenance-free, strong adhesion, long weather resistance, etc., coating the fluorocarbon paint on the plastic powder outer layer of the light pole can play a very good protective effect, making it It is not a problem to maintain the gloss of the exterior paint on the surface for more than ten years. The service life of street light poles is mostly long-term, and the use of correct and high-quality workmanship will benefit for life, once and for all.
