Werksbeginsel van 'n plasmaskoonmaker

Plasma cleaners use plasma discharge to generate a high-energy oxidation reaction. Using oxygen or a mixed gas (such as oxygen + hydrogen) in the discharge zone, they form an ion plasma (energy range 5-15 eV). The high-energy electrons and radiation from these plasmas decompose surface contaminants (organic matter oxidation rate >90%), wat gasvormige of oplosbare produkte produseer. Hierdie tegnologie bied chemiese-vrye, nie-kontakskoonmaak, wat dit geskik maak vir oppervlakbehandeling van metale (soos vlekvrye staal en aluminium) en polimere (soos PTFE), en is besonder goed-geskik vir die skoonmaak van presisie elektroniese komponente en mediese toestelle.

Wat skoonmaakdoeltreffendheid betref, wissel tipiese behandelingstye van 2-10 minute per bondel. Dit kan nanoskaal kontaminante (deeltjiegrootte) verwyder<100 nm), reduce surface contact angles by over 40°, and significantly improve material adhesion. Important operating parameters: maintain power between 50-1000W, air pressure between 10-100 Pa, and avoid overheating the substrate (temperature <150°C).
