When it comes to epoxy zinc-rich primers, most readers may feel unfamiliar. Don't understand it at all. In fact, it has been widely used. In order to let more people understand it, let's talk about the advantages of epoxy zinc-rich primer and the matters needing attention during construction. I hope all friends will take a look.

Inventory the advantages and precautions of epoxy zinc-rich primer?

Epoxy zinc-rich primer But from its name, many people do not know what it is. In fact, it is composed of zinc powder, epoxy resin, solvent and additives. The zinc powder in it mainly plays the role of anti-rust pigment and anti-corrosion. To say that it has many advantages, the most obvious one is that it has cathodic protection. According to the electrochemical anti-corrosion mechanism, it can better protect the steel when it is used, and it also has a corrosion inhibition effect, because the zinc powder inside The chemical properties of the zinc salt produced by the corrosive medium will become very stable and the structure will be very compact, which will block the corrosion, and its salt spray resistance is also very strong, because the higher the zinc content, the salt resistance. The fog is getting stronger. These are its advantages.

After we know the advantages of epoxy zinc-rich primer, we also need to understand some things that need to be paid attention to during construction. When using epoxy zinc-rich primer, the steel should be sandblasted, and it must reach Sa2.5 level rust removal Standard, the roughness is also to reach 30-70μm. When using the main paint and curing agent, it must be added in strict accordance with the ratio, and it needs to be used up within the specified time. And during construction, its temperature should be controlled at 5-40 °C, and the temperature of the substrate should be 3 °C higher than the dew point temperature. When the interval between the primer and the next paint is more than 7 days, the primer needs to be brushed during application, and the zinc salt on the surface should also be removed. Construction workers must remember to avoid contact with acids and alkalis.

The mechanism of anti-corrosion coatings

Anti-corrosion coatings can be divided into corrosion-resistant coatings, which require acid or alkali resistance, and acid and alkali resistance can be alternated or performed simultaneously. The pH value of the corrosion medium can be corroded from 1 to 12. The coating has low alkali resistance, acid aging resistance and good adhesion of the anti-corrosion layer. The anti-corrosion principle of anti-corrosion coating mainly includes three aspects: electrochemical action, chemical principle and physical principle.
