Pollen Accumulation

Pollen-deposit-contamination, it manifests as irregular organic layers, formed from airborne pollen adhering to surfaces in humid environments. These deposits, they exhibit unique patterns influenced from regional vegetation, creating patchy films that trap moisture and degrade substrates over time. In laser cleaning applications, the contamination persists tenaciously on porous stones, where organic residues carbonize unevenly under beam exposure, complicating complete removal. On metals, it seems that adhesion weakens faster, yet fragments scatter, risking secondary soiling. This layer, dependent from pollen composition, demands pulsed lasers for selective ablation, avoiding substrate damage that demonstrates in varied material behaviors. Shows effectiveness through controlled fluence, leading to cleaner surfaces without residue remnants.
