Analysis Of Three Effects Of Using Paint in Container Houses

The main effects of using paint on the materials of prefabricated houses include corrosion inhibition, cathodic maintenance, and shielding.
1. Corrosion inhibition effect: The rust prevention effect of paint largely relies on the corrosion inhibition effect of anti rust pigments. Taking zinc phosphate as an example, it has the ability to form a basic complex, which can further complex with the polar groups of the paint base to form a stable cross-linking complex. This not only enhances the water resistance and adhesion of the paint film, but also forms a strong iron zinc phosphate complex on the surface of the light steel layout color steel panel room, hindering the formation and development of corrosion and reducing the corrosion rate of the light steel layout color steel panel room.
2. The effect of cathodic maintenance: The cathodic maintenance effect of using zinc powder, resulting in epoxy zinc rich paint and inorganic silicate zinc rich paint, has good rust prevention effect and is a primer in heavy-duty anti-corrosion coating systems. The high content of zinc powder closely contacts the layout of light steel because the potential of zinc is lower than that of light steel layout, and the corrosion current will flow from zinc to light steel layout. Zinc powder is mainly corroded, thus maintaining the layout of light steel. The corrosion products of zinc powder in the atmosphere are awkwardly soluble in alkaline salts, which will fill the empty space in the coating, so they also have maintenance effects.
3. Shielding effect: The paint, through outstanding construction, covers the surface of the light steel layout, effectively blocking the contact between the light steel layout and the external corrosive environment. That is to say, paint hinders the corrosion of oxygen, water vapor, and other corrosive ions in the atmosphere on the materials of light steel layout color steel panel houses.
