Anti rust method, according to the corrosion mechanism of steel, steel rust method is divided into 4 kinds. One is to change the composition of steel. That is, in the process of steel smelting process, such as copper, chromium and other alloy elements to improve the ability to resist rust, this is stainless steel, because the cost is too high, it is difficult to apply in a large number of projects.
Currently only used for small decorative works. Two is the cathodic protection method, the component and the power cathode is connected, so that the electronic components of the lost, the internal steel has always maintained the potential balance without rust.
This method is currently only used for the protection of water or underwater structures. Three is in the component surface with metal coating protection, such as electroplating or hot dip galvanized, etc., generally used for thin plate or small diameter decorative pipe, such as steel pipe.
Four is in the steel surface coating to non-metallic protective layer, cut off the steel in air contact and achieve the purpose of anti rust, this method is convenient, cost is relatively low, so in the engineering application of advertising, single durability is poor, in general a few years later need to re spray.
