Session 12: Advances in Surface Finishing
Removing hazardous coatings can be costly, complicated, and time-consuming. Lead, Hex Chrome, and other hazardous coatings can easily cause health concerns if not removed appropriately. Laser cleaning offers a solution to this issue by creating a clean work environment where the operator is safe from high exposure levels while also removing the coatings efficiently.
Advances in Surface Finishing Technology
General Surface Finishing
The nature of this study is to explore the use of laser cleaning on lead paint, hex chrome, nuclear decontamination, and other hazardous coatings. Laser cleaning of hazardous material prevents harmful impacts to operator and environment the coating needs to be removed from. The study shows cases using handheld cleaning lasers on hazardous paints and other coatings on metallic substrates. The hazardous coating is ablated into a vaporous form and extracted immediately into a filter system, preventing the operator from being exposed to harmful levels of hazardous material. Alpha and Beta particles were measured before and after laser cleaning to get an understanding of contamination removal.
