The method of anti-corrosion of iron tower paint
The tower is one of the important infrastructures in the power system, which is exposed to natural factors such as wind, rain and sun exposure for a long time, and is prone to corrosion. In order to prolong the service life of the tower, anti-corrosion treatment is required. Paint anti-corrosion is a commonly used method, and this article will introduce the method of anti-corrosion of iron tower paint.

1. Preparations.
Before the anti-corrosion treatment of the tower paint, the following preparations need to be made:
1.Clean the surface of the tower: clean the dirt, dust, rust, etc. on the surface of the tower to ensure that the surface is dry and free of oil.
2.Inspect the surface of the tower: Check the surface of the tower for cracks, holes and other defects, and repair them if necessary.
3.Prepare the paint: Choose the appropriate anticorrosive paint according to your needs, and prepare auxiliary materials such as thinners and hardeners.
4.Tool preparation: Prepare painting tools such as spray guns, brushes, rollers, etc.
Second, paint anti-corrosion treatment method.
The method of anti-corrosion treatment of tower paint mainly includes the following steps:
1.Primer coating: Primer is applied to the surface of the tower, and the role of the primer is to seal surface defects, improve adhesion and increase the thickness of the coating. Commonly used primers are epoxy zinc-rich primer, iron red primer, etc. When applying the primer, it needs to be evenly applied and there are no omissions.
2.Topcoat coating: After the primer has dried, the topcoat is applied. The role of the topcoat is to provide long-term protection against corrosion. Commonly used topcoats are acrylic topcoats, polyurethane topcoats, etc. When coating the topcoat, it needs to be evenly coated, the color and luster are consistent, and there is no sagging.
3.Coating thickness inspection: After the coating is completed, the coating thickness needs to be tested to ensure that the coating thickness meets the requirements. Commonly used detection methods include thickness gauge detection method, magnetic detection method, etc. If the coating thickness is found to be insufficient, it needs to be reapplied.
4.Coating protection: After the coating is completed, the coating needs to be protected to avoid bumps, scratches and other phenomena. Commonly used protective measures include coating covering protective film, waxing of the coating surface, etc.
3. Precautions.
When carrying out the anti-corrosion treatment of tower paint, the following matters need to be paid attention to:
1.Choose high-quality paint: High-quality paint can provide better corrosion protection, so you need to choose the right paint brand and model according to your needs.
2.Control the coating environment: The coating environment has a great impact on the coating effect, so it is necessary to control the ambient temperature, humidity and other factors to ensure the coating quality.
3.Coating in strict accordance with the technological process: Coating in strict accordance with the technological process can ensure the quality of coating and improve the anti-corrosion effect.
4.Pay attention to safety: Paint contains flammable and explosive substances, so you need to pay attention to safety to avoid accidents such as fires.
