Background
The building steel has the advantages of high strength, good plasticity and toughness, light dead weight, simple manufacture, short construction period, suitability for large span, high height, heavy load and the like, and the steel is widely applied in the building industry. However, the steel has poor corrosion resistance and rust resistance, the economic loss caused by corrosion is about 4% of the total national economic yield each year, the corrosion of the steel structure not only causes economic loss, but also brings hidden danger to the safety of the structure, and engineering accidents caused by steel rust are also frequent. Therefore, the corrosion protection treatment of steel structures is of great economic and social importance.
In the prior art, the steel structure needs to be subjected to corrosion protection treatment, generally, the corrosion protection treatment is carried out by adopting a treatment mode of coating an anti-corrosion layer, and the anti-corrosion layer generally comprises the following steps:
1. Surface treatment, including polishing rust removal and preheating treatment;
2. detecting the surface of the steel structure, and performing anti-corrosion treatment after the detection is qualified;
3. forming a bottom anti-corrosion layer on the surface of the steel structure through a spraying machine or an electrochemical mode;
4. After the bottom anti-corrosion layer is solidified, an anti-corrosion film is adhered to form an intermediate anti-corrosion layer (in some steel structure anti-corrosion treatments, the intermediate anti-corrosion layer is also formed by sampling spraying or electrochemical mode);
5. and after the intermediate layer anticorrosive layer is solidified, spraying to form an outer anticorrosive layer.
