Egwyddor Gweithio Glanhawr Plasma

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%), yn cynhyrchu cynhyrchion nwyol neu hydawdd. Mae'r dechnoleg hon yn cynnig glanhau cemegol, di-gyswllt, sy'n ei gwneud yn addas ar gyfer trin wynebau metelau (fel dur di-staen ac alwminiwm) a pholymerau (fel PTFE), ac mae'n arbennig o addas ar gyfer glanhau cydrannau electronig manwl gywir a dyfeisiau meddygol.

O ran effeithlonrwydd glanhau, mae amseroedd triniaeth nodweddiadol yn amrywio o 2-10 munud fesul swp. Gall gael gwared ar halogion nanoscale (maint gronynnau<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).
