A588 weather-resistant steel plate has many outstanding features such as corrosion resistance, high strength and toughness, and durability. It is an alloy steel that has undergone special pretreatment, corrosion resistance, and rust resistance. In order to make the A588 weathering steel plate corrosion resistant, a special coating process is used. Here we introduce the coating process of A588 weathering steel plate.
First, surface treatment is employed. Usually, it is necessary to remove the rust and scale on the surface of the steel plate. Abrasive cleaning and chemical cleaning are usually used. The surface of the steel plate must be cleaned to make it smooth and remove dirt or other impurities on the surface.
Secondly, welding repair process is adopted to repair the welding defects of the steel plate. This process is mainly to remove the welding defects and make the steel plate surface smooth and uniform. Welding repair is generally electro-slag welding, argon arc welding and other methods.
The third is to use electrolytic degreasing process. This process is to remove excess oil, grease and other organic matter on the surface of the steel plate. Degreasing is carried out in an electrolytic cell containing a special degreasing agent, and the steel plate passes through the electrolytic cell with direct current.
Fourthly, pickling treatment process is needed. It is mainly used to clean the steel plate surface, remove oxide skin and other harmful substances. This step is to remove rust, oxide and other impurities on the steel plate surface by immersing the steel plate in the pickling bath.
Fifthly, spraying paint process is adopted. This process is to coat the surface of the steel plate with a layer of paint to prevent corrosion and increase the corrosion resistance of the steel plate. The spraying paint process is mainly to mix the paint with a mixture of binders, pigments, and curing agents, and spray the paint onto the steel plate with a sprayer.
Sixthly, the finishing process is adopted. This process is mainly to smooth the surface of the steel plate. The finishing process is mainly to use polishing wheels to smooth the surface of the steel plate. The whole surface of the steel plate can be made into a smooth and bright surface.
Finally, a passivation process is adopted. The purpose of this process is to form a protective layer on the surface of the steel plate to prevent rust. Commonly used passivation processes include electrochemical passivation, dipping passivation and spray passivation.
The above coating process is used to coat the A588 weathering steel plate. Through these processes, A588 weather-resistant steel plate has the characteristics of corrosion resistance and long shelf life. It plays an important role in protecting the steel plate from any wear and tear.
