The anti-corrosion and rust prevention methods for BV Ah36 and Eh32 marine steel plates mainly include the following:

 

Coating protection:

 

Anticorrosive paint coating: This is the most common protection method. Applying anticorrosive paint on the surface of the steel plate can effectively isolate the steel plate from the outside air, water, and electrolyte solution to prevent corrosion. The selection of anticorrosive paint should be determined according to the ship's operating environment and requirements. For example, in a seawater environment, anticorrosive paint with good seawater corrosion resistance is needed. At the same time, regularly inspect and maintain the coating and promptly repair damaged areas to ensure the integrity and protection effect of the coating.

Special coatings: In addition to ordinary anticorrosive paint, there are some special coatings that can be used for the anti-corrosion and rust prevention of marine steel plates, such as hydrophobic coatings and antifouling coatings. Hydrophobic coatings can make the surface of the steel plate hydrophobic, reducing the adhesion of water on the steel plate surface and thus reducing the possibility of corrosion. Antifouling coatings can prevent marine organisms from adhering to the steel plate surface and avoid corrosion and fouling caused by biological adhesion.

 

Metal plating protection:

 

Hot-dip galvanizing: Immerse the steel plate in high-temperature zinc liquid to make the zinc liquid adhere to the steel plate surface and form a zinc coating. The electrode potential of zinc is lower than that of iron. In a corrosive environment, zinc will be corroded before iron, thereby protecting the steel plate from corrosion. Hot-dip galvanized coatings have good corrosion resistance and adhesion and are suitable for marine steel plates exposed to the marine environment for a long time.

Electroplating: Plate a layer of metal such as zinc, nickel, or chromium on the steel plate surface by electrolysis. The electroplated coating can improve the corrosion resistance and wear resistance of the steel plate, but during the electroplating process, attention should be paid to controlling the thickness and quality of the coating to ensure the protection effect.

 

Cathodic protection method:

 

Sacrificial anode cathodic protection: Connect a metal more active than iron, such as zinc or aluminum, as a sacrificial anode on the steel plate. In a corrosive environment, the sacrificial anode will be corroded first, and the released electrons will flow to the steel plate, making the steel plate a cathode and thus being protected. This method is simple and easy to implement and has low cost. It is suitable for small ships and local anti-corrosion.

Impressed current cathodic protection: Apply a certain current to the steel plate through an external power source to make the steel plate a cathode and thus inhibit the occurrence of corrosion. This method requires professional equipment and technology and is suitable for large ships and areas with high anti-corrosion requirements.

Controlling environmental factors:

 

Keep dry: Minimize the contact time between the steel plate and water and avoid the steel plate being in a humid environment for a long time. In the design and construction of ships, the drainage system should be reasonably arranged to ensure that the water on the steel plate surface can be discharged in time.

Control seawater quality: Regularly treat seawater to remove impurities and corrosive substances in seawater and reduce the corrosiveness of seawater. For example, seawater filters and seawater desalination equipment can be used.

 

Regular maintenance and inspection:

 

Regularly maintain and inspect ships to promptly discover and deal with corrosion problems of steel plates. For corroded areas, rust removal and repair should be carried out in time to prevent further expansion of corrosion.

Establish a complete maintenance record and file to track the corrosion situation and protection effect of the steel plate so that anti-corrosion measures can be adjusted in time.
