Painting Process: Building a Basic Protective Barrier
- A widely used basic surface treatment method that isolates external corrosive media through protective paint application.
- Special anti-corrosion paint is evenly applied through high-pressure spraying, forming a dense paint film on the fuel tank surface.
- Weather-resistant and oil-resistant paint resists rain, oil, and atmospheric corrosion while enhancing appearance.
- Surface must be degreased and derusted before application to ensure paint adhesion and prevent peeling or flaking.
2
Electroplating Process: Enhancing Wear and Corrosion Resistance
- Electroplating significantly improves surface wear resistance and corrosion resistance through electrolytic metal coating application.
- Commonly used coating materials possess excellent chemical stability, effectively isolating air and moisture to prevent steel corrosion.
- Electroplated surfaces have higher hardness, resisting minor impacts and friction damage during use.
- Suitable for complex operating conditions, especially for applications with high protection requirements.
3
Phosphating Process: Foundation for Enhanced Adhesion
- Often used as a base treatment, providing a good adhesion foundation for subsequent coatings.
- A uniform phosphate film is formed through chemical reaction on the fuel tank surface.
- The porous structure of the phosphate film enhances adhesion of subsequent paint or electroplating layers, preventing separation from the substrate.
- Phosphating film itself provides initial corrosion resistance, blocking corrosive media penetration and improving overall protective effect.

Shot Blasting Process: Optimizing Surface Cleanliness
- Primarily used for surface cleaning and strengthening through high-speed impact treatment.
- High-speed shot impacts remove impurities such as rust, scale, and oil, resulting in a clean but rough surface.
- Process induces plastic deformation on the surface, creating residual compressive stress and improving steel fatigue resistance.
- Treated surface is more conducive to subsequent protective processes, indirectly enhancing overall protection stability and durability.
