Paint-residue contamination arises from degraded coatings on surfaces. This contamination, it forms unique irregular patterns, like patchy layers from uneven paint application and environmental weathering. Formation occurs through adhesion of pigments and binders, creating thick, non-uniform deposits that resist initial breakdown.
Removal challenges emerge in laser cleaning. Residue exhibits strong bonding to substrates, thus demands precise energy pulses to avoid substrate damage. On metallic materials, it shows thermal stability and charring tendency, complicating clean detachment. For polymeric surfaces, behavior differs; residue peels in flakes but leaves adhesive traces. Treatment applies laser ablation, and surface already exhibits reduced roughness, though traces still persist in crevices. Analysis confirms these patterns, so adjustment of parameters enhances efficiency.
