1、 Requirements for painting steel

1. Surface cleaning: Before painting steel, the surface of the steel must be thoroughly cleaned without any impurities or dirt, otherwise it will affect the painting effect.

2. Tightness: Steel should be tightly coated with paint to prevent rust. If there is a lack of tightness, it will lead to rusting of the steel.

3. Quality: Painting quality is one of the important standards for judging whether steel is aesthetically pleasing. The painting of steel should be uniform and delicate, and there should be no situation where the coating is too thick or too thin.

4. Viscosity: By selecting appropriate paint materials and brushing them in a suitable environment, the viscosity and internal structure of the paint will be maximized.

5. Glossiness: If the steel surface needs to have glossiness, the paint should be sprayed or rolled multiple times during brushing.

2、 The role of painting steel

1. Rust prevention: After the steel surface is painted, a protective film can be formed to prevent rust. This is very important for the long-term use and operation of steel.

2. Beautification: After painting the surface of steel, it can beautify the appearance of the steel, improve the overall aesthetics of the steel, and also reduce the glossiness of the steel surface, making the visual effect more comfortable.

3. Protection: Brushing paint on the surface of steel can protect its ion layer and microstructure to a certain extent, enhance the corrosion resistance of steel, and improve its service life.

4. Heat resistance: After painting the surface of the steel, it can improve the heat resistance of the steel, making it more stable to operate at higher temperatures.

In short, steel painting is an important processing technology and plays a crucial role in the use of steel. It is necessary to choose appropriate paint materials based on specific steel materials and working environments, paying attention to the requirements of painting, in order to achieve the best rust prevention, beautification, and protection effects.
