What are the anti-corrosion methods for solar street light poles?

With the application of solar energy, the use of solar street lights is becoming more and more extensive. Because the working environment of the solar street light is outdoors, the requirements for supporting the light pole are better. To prevent the light pole from rusting and corroding and reducing the structural strength, it is necessary to carry out anti-corrosion treatment on the solar street light pole. So what are the anti-corrosion methods for solar street light poles?

1. Surface spray treatment

The first good method is to hot-dip galvanize the light pole, the zinc layer of the hot-dip galvanized light pole is firmly combined with the steel pole, the zinc layer does not peel off, and the anti-rust effect is particularly good. Then spray plastic treatment on the surface of the light pole, the color can be specified by the customer, and the outdoor high-quality plastic is used so that the anti-rust time of the light pole can last for more than ten years.

2. High temperature plastic spraying

This is a new technology developed in recent years. The basic working principle is to spray nylon on the surface of the prepared workpiece under the heating and melting of the flame, so as to obtain the required spray coating.

3. Powder electrostatic spraying

Powder electrostatic spraying means that the powder is negatively charged. Under the action of electrostatic force and compressed air, the powder is evenly adsorbed on the workpiece. This method can make the surface of the lamp pole more uniform and flat. Of course, electrostatic spraying also has two methods of painting and spraying.

4. Hot dip galvanizing treatment

The process and method of immersing pre-treated parts in a molten zinc solution to form zinc and zinc-iron alloy coating on the surface. The thickness of the zinc layer is 65-90um. The zinc layer of the galvanized parts should be uniform and smooth, with nodules and excess agglomeration. The zinc layer should be firmly combined with the steel rod, and the zinc layer should not peel off or protrude.
