Weathering rust steel plate features
Real rust steel plate/weathering steel: uniform red rust, good color fastness, no peeling, no slag, no rust water flowing in the later period, super corrosion resistance, fake rust steel plate: black color.
Ordinary steel/carbon steel, poor mechanical properties of steel, severe rust in the early stage, peeling, slag, rusty hot metal flow to pollute the environment, service life is super short, and serious corrosion.
The rusted steel plate will change with the change of time, and its color brightness and saturation are higher than that of general structure materials, so it is easy to highlight under the background of garden green plants.
Principle of Steel Rusting
In the early stage of corrosion of weathering steel, the rust layer formed on the surface is denser than carbon steel, and there are relatively few cracks and holes; after 25d, carbon steel and weathering steel are partially delaminated, and there is no difference in corrosion products. The difference is mainly the alloy in the rust layer The role of elements. The precipitation of Cu and Cr alloy elements in the rust layer of weathering steel, which is gathered in the cracks, can resist the intrusion of moisture and harmful ions in the atmosphere and prevent further corrosion of the base metal. So as to achieve the effect of resistance to atmospheric corrosion!
Rust treatment
The rust-stabilizing treatment method is to produce a rust-stabilizing coating on the surface of weather-resistant steel by chemical methods. It is a kind of rust that inhibits the outflow of steel at the initial stage of use and stabilizes it. The installation is very similar, in fact, the general coating is to block the outside air and the outside of the steel to suppress rust, and the rust stabilization treatment method is to promote the rust stabilization. There is a big difference in function. If the coating deteriorates after the coating is applied, it will cause peeling of the paint, which will rust, and it has to be re-painted in order to maintain the beauty.
