Wanpela 'corona triater electrode' em i wanpela 'conductive element' we i save 'shape' 'high-voltage field' long 'treating gap'. Ol i save putim 'alternating current' long 10 kHz i go inap 40 kHz namel long 'electrode' na wanpela 'grounded roll', na win insait long spes i save bruk i go insait long wanpela kol plasma bilong ol 'ions', 'electrons' na 'ozone'. Dispela plasma i save bomim pes bilong polima, na brukim ol kabon-haidrojen bon na pasim ol oksijen-bearing fanksenel grup olsem haidroksil, kabonil na kaboksil radikal. Risal bilong en em i wanpela bikpela eneji bilong pes, we ol i save skelim long 'dynes' long wan wan sentimita.
Dispela 'electrode' i no save tromoi 'voltage' i go insait long spes. Seip bilong en i bosim we hap fil i stap long en, hamas bikpela wara i go aut, hamas hat i kamap na hamas tritmen i pundaun long olgeta hap bilong web. Wanpela 'corona triater electrode' we ol i no makim gut i save kamapim 'banding', 'pinholes' na 'backside treatment', na wanpela 'well-'matched i save givim wankain 'dyne level' long arere i go long arere wantaim liklik pawa tru.
