Why weather resistant rust steel landscape sun no wind and rain close rust?

Go out often to play, in some scenic spots in some may see the fair scenery, where they establish long-term, wind and rain no color of the sun rust steel plate pattern, do you know why?

This is a natural rust, rust steel landscape is known as rust steel (also known as rust steel), the addition of phosphorus ordinary steel, copper, chromium, nickel and steel surface density and strong adhesion after the protective film and other trace elements, hinder the development of corrosion and diffusion within, protect the rust layer to the underlying substrate to slow down the corrosion rate. High corrosion resistance, because of the rust steel plate in the natural environment, in general rust steel plate from a new plate, in order to produce a stable, dense red rust protective layer required 1? A dry area of 2 years can also be a longer part. In order to generate even simple homogeneous yellow rust, we need about 1 month. During this process, the color component changes uncontrollably, from blue-black to orange-red, then to rusty red, reddish-brown, and finally, violently, uniformly.

In view of this situation can slow down the promotion of rust, the principle is a series of physical and chemical processes, accelerate the corrosion process, the workpiece has reached a relatively stable state of color to complete the first stage of the week, although the process of the state will produce color changes in the future, but the change is very mild and gradual.

Rust steel plate manufacturers together to experience the study of rust steel plate learn from Japan JFE steel company rust stabilization technology, through the deformation of the coating example, increase the oxygen permeability of the coating, the coating can be so slow down the rust cambium, the coating will be added to some of the corrosion resistance of the rust layer enrichment elements. Because the coating holes are nanoscale holes, the outflow of corrosion products can be prevented to prevent the occurrence of rust losses. The rust plate coating of the dense rust layer that has been formed has shed a certain number of service years, and after this time under the coating, the rust will not be lost again.
