Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing, and in particular to a method for protecting a surface coating of an oil tank shell based on electronic data processing. Background Art

[0002] With the rapid development of new energy vehicle technology, the fuel tank shell still plays an important role in these vehicles. Although new energy vehicles use electricity as the main power source, in extended-range hybrid vehicles and fuel cell vehicles, the fuel tank shell is usually used to store coolant, lubricating oil or other special-purpose working fluids. In order to improve the corrosion resistance and long-term reliability of these fuel tank shells, a protective coating is usually applied to their surface. In the actual operating environment of new energy vehicles, the surface coating of the fuel tank shell faces more complex challenges. For example: High temperature and high humidity environment: During the operation of new energy vehicles, components such as motors and batteries will release a lot of heat, causing the temperature of the surrounding environment of the fuel tank to rise. Combined with high humidity conditions, it is easy to accelerate the aging and corrosion of the coating. Frequent vibration and impact: The vibration during vehicle operation and the impact of the external environment may cause fine cracks in the coating, thereby reducing the protective effect of the coating. Chemical corrosion: Since the liquids used in some new energy vehicles (such as coolant or electrolyte) have strong chemical activity, once they leak or evaporate and contact the fuel tank shell, the corrosion rate of the coating may be aggravated.

[0003] The existing protection methods for the coating of the fuel tank shell are mainly focused on the following aspects: extending the coating life by enhancing the corrosion resistance and physical properties of the material, but being unable to respond to new problems in a dynamic environment in real time, and using a fixed thickness of protective agent to cope with complex environments, which lacks flexibility and intelligence. Therefore, there is an urgent need for a surface coating protection method for the fuel tank shell of a new energy vehicle based on electronic data processing, which combines real-time data collection, intelligent analysis and automated coating technology to provide an accurate coating protection solution for complex environments.
