A study of particulate matter concentration released during laser paint removal process on car coated substrate

Normalization mass (N) of particulate matter (PM) per one laser shot and 1.0 cm2

released during the laser irradiation were measured on three different types of car coated substrate samples A,

B and C by using DustTrak Aerosol Monitor 8520. The highest N of PM1.0 and PM10.0 were 0.0485 mg/shot/cm2

and 0.0766 mg/shot/cm2

mg/shot/cm2

safe than conventional chemical stripping process in term of health implications prevention and safety
