Port machinery and equipment is an indispensable and important facility in port logistics, however, because the port machinery and equipment are in a high humidity, high salinity, and dusty environment for a long time, its anti-corrosion work is particularly important. This article will discuss the importance of anti-corrosion of port machinery and equipment, anti-corrosion methods and anti-corrosion coating materials.

First, the importance of anti-corrosion of port machinery and equipment.
Port machinery and equipment is an important part of port logistics, and its operation directly affects the operational efficiency of the port. However, due to the long-term exposure of port machinery and equipment to high humidity, high salinity and dusty environment, the equipment is prone to corrosion. Corrosion will not only affect the appearance of the equipment, but also reduce the performance and service life of the equipment, and even lead to equipment damage and safety accidents in severe cases. Therefore, the anti-corrosion work of port machinery and equipment is very important.
Second, the method of anti-corrosion of port machinery and equipment.
1.Surface treatment.
Surface treatment is an important part of anti-corrosion work, the purpose of which is to remove impurities such as oil, rust and oxides on the surface of the equipment, improve the roughness of the surface, and increase the adhesion between the coating and the substrate. Common surface treatment methods include mechanical cleaning, chemical cleaning, and electrochemical cleaning.
2.Coating protection.
Coating protection is one of the main methods of anti-corrosion of port machinery and equipment. By applying an anti-corrosion coating on the surface of the equipment, the metal surface is isolated from the external environment, so as to achieve the purpose of anti-corrosion. Commonly used anti-corrosion coating materials include paints, anti-rust oils, coatings, etc.
3.Electrochemical protection.
Electrochemical protection is to achieve the purpose of anti-corrosion by changing the electrochemical properties of metals. Commonly used electrochemical protection methods include cathodic protection and anodic protection. Cathodic protection is the cathodic polarization of the metal surface by an applied current, thereby inhibiting the progress of corrosion;Anode protection is the use of an applied current to polarize the metal surface to improve corrosion resistance.
Third, the selection of anti-corrosion coating materials.
When choosing an anti-corrosion coating material, it is necessary to consider its weather resistance, water resistance, corrosion resistance and mechanical properties. Commonly used anti-corrosion coating materials include paints, anti-rust oils, coatings, etc. Paint has good protective properties and decorative properties, and can form a dense paint film on the metal surface, effectively isolating oxygen and moisture in the air, so as to achieve the purpose of anti-corrosion. Anti-rust oil can form a layer of anti-rust film on the metal surface, which has a good anti-rust effect, but has poor weather resistance and decorative properties. Coatings have a variety of types and uses, and the right coating can be selected according to different use environments and requirements.
Fourth, case analysis.
Taking a port terminal as an example, its cargo handling equipment has been in a high humidity, high salt, and dusty environment for a long time, and the equipment is prone to corrosion. To address this issue, the terminal employs a variety of anti-corrosion measures. First of all, the surface of the equipment was thoroughly cleaned and rusted to ensure the cleanliness and roughness of the surface. Secondly, a high-performance anti-corrosion coating is adopted, which has good weather resistance, water resistance and corrosion resistance, and can effectively isolate oxygen and moisture in the air, so as to achieve the purpose of anti-corrosion. In addition, the structure of the equipment is optimized to reduce the stress concentration and fatigue damage of the equipment, thereby improving the durability and reliability of the equipment. Through the implementation of these measures, the cargo handling equipment of the terminal has been effectively protected, the service life of the equipment has been extended, and the operational efficiency of the terminal has also been improved.
V. Conclusions. The anti-corrosion work of port machinery and equipment is one of the important measures to ensure the normal operation of equipment. In practice, it is necessary to select appropriate anti-corrosion measures according to the use environment and requirements of the equipment, including surface treatment, coating protection, electrochemical protection, etc. At the same time, it is also necessary to select the appropriate anti-corrosion coating material according to the actual situation to achieve the best anti-corrosion effect. Through the implementation of scientific and reasonable anti-corrosion measures, it can effectively extend the service life of port machinery and equipment, improve the durability and reliability of equipment, and provide guarantee for the normal operation of the port.
