What role does paint play in the production of mobile homes?

【1】The effect of shielding

Through superb construction, the paint is covered on the surface of the mobile room, which can effectively block the contact between the light steel structure and the external corrosive environment. That is to say, the paint prevents the corrosion of the container mobile room material by oxygen, water vapor and other corrosive ions in the atmosphere.

【2】Effect of cathode maintenance

Using the cathodic protective effect of zinc powder, the epoxy zinc-rich paint and inorganic silicate zinc-rich paint have good anti-rust effect, and are the first choice for heavy-duty anti-corrosion paint systems. High content of zinc powder is in close contact with the mobile home, because the potential of zinc is lower than that of the light steel structure, the corrosion current will flow from the zinc to the light steel structure, and the zinc powder will be corroded first, thus maintaining the mobile home. Zinc powder is corroded in the atmosphere and turned into soluble alkali salt, which will fill the gap in the coating, so it also has a protective effect.

【3】Effect of corrosion inhibition

The anti-rust effect of paint relies to a large extent on the corrosion inhibition effect of anti-rust pigments. Taking zinc phosphate as an example, it has the function of forming a basic bond, which can further complex with the polar group of the paint base to form a stable bond, which not only enhances the water resistance and adhesion of the paint film, but also in the container The surface of the mobile home material forms a strong iron-zinc-phosphate compound, which prevents the formation and development of rust and reduces the corrosion rate of the container mobile home.
