The most common anti-rust process for solar street light poles is hot rolled steel plate + hot / cold galvanizing + spray + protective film:
The solar street light pole will hardly rust after cold/hot galvanizing treatment (except for the case of trachoma when the light pole is welded), then the only factor that will affect the appearance of the street light is the exterior paint. After the solar light pole is galvanized The last anti-corrosion coating process will be carried out - spray molding.
Spraying is made of outdoor plastic powder, or better outdoor bright plastic powder, but after actual use, it is found that the service life of outdoor plastic powder can not reach 10 years or even 20 years, while outdoor bright plastic powder is used outdoors for three years. After that, the luster of the surface of the solar lamp post will gradually dim and then start to change color and paint off. This is a good plastic powder. The plastic powder with poor quality can be completely changed in one year. The biggest disadvantage of outdoor plastic powder is that it is very poor in aging resistance.
Therefore, at this time, it is necessary to add a protective film on the surface. The galvanizing is for rust prevention. The plastic blasting is for the sake of beauty, and the rust prevention is achieved. If the appearance is good, then adding a protective film is perfect. Outdoor powders have poor weatherability. If they can be packaged with a super-weatherable paint, they can maintain their true color for a long time. However, this paint is not difficult to find. It is a "fluorocarbon paint". The fluorocarbon paint has excellent anti-corrosion performance, maintenance-free, strong adhesion, long-term weather resistance, etc. The fluorocarbon paint can be applied to the outer layer of the plastic powder rod of solar energy to provide a very good protection effect. It is not a problem that the gloss of the surface of the surface is maintained for more than ten years.
The above is about the use of paint for solar street light poles. The safety and reliability of solar street lights is very important. The maintainability of solar street lights is also very important. In different environments, such as foggy weather, rain, and pollution, solar street lights must meet road lighting safety requirements. The lifespan of solar street light poles is mostly long-term, and the correct quality workmanship will benefit lifelong and once and for all.
