Structural Parts Pre-treatment

Short Description:

Structural parts pre-treatment is a fundamental and critical stage in the coating process, primarily applied to steel structures, aluminum alloys, and welded components to clean and activate the surface by removing oil, oxides, welding residues, and other contaminants, while forming a uniform chemical conversion layer. The process typically includes degreasing, spray cleaning, water rinsing, surface conditioning, and phosphating. Through multi-stage chemical treatment and precise process control, it significantly improves surface cleanliness and coating adhesion. In addition, the pre-treatment system is equipped with circulation filtration and automatic control of temperature and chemical concentration, ensuring bath stability and process consistency. This provides a high-quality substrate for subsequent coating processes and enhances overall corrosion resistance and service life of the coating system.
