Mu nkhani yapitayi tinayang'ana kwambiri pa imodzi mwa njira ziwiri zosiyana zodzichiritsira mu ma capacitor a filimu opangidwa ndi zitsulo: kudzichiritsa kodzichiritsa, komwe kumadziwikanso kuti kudzichiritsa kwamphamvu kwambiri. Munkhaniyi tiona mtundu wina wa kudzichiritsa, kudzichiritsa kwamagetsi, komwe nthawi zambiri kumatchedwa kudzichiritsa kwamphamvu kwambiri.

Kudzichiritsa Kokha ndi Ma Electrochemical

Kudzichiritsa kotereku kumachitika nthawi zambiri mu ma capacitor a aluminiyamu okhala ndi magetsi otsika. Njira yodzichiritsira yokha ndi iyi: ngati pali cholakwika mu filimu ya dielectric ya capacitor ya filimu ya metalised, magetsi atawonjezeredwa ku capacitor (ngakhale magetsi ali otsika kwambiri), padzakhala mphamvu yayikulu yotuluka kudzera mu vutolo, lomwe limafotokozedwa chifukwa kukana kwa insulation kwa capacitor kuli kotsika kwambiri kuposa mtengo womwe wafotokozedwa mu mikhalidwe yaukadaulo. Mwachiwonekere, pali ma ionic currents ndipo mwina ma electronic currents mu leakage current. Chifukwa mitundu yonse ya mafilimu achilengedwe ali ndi kuchuluka kwa kuyamwa kwa madzi (0.01% mpaka 0.4%) ndipo chifukwa ma capacitor amatha kukhala ndi chinyezi panthawi yopanga, kusunga ndi kugwiritsa ntchito, gawo lalikulu la mphamvu ya ionic lidzakhala ma O2- ndi H-ion currents omwe amachokera ku madzi omwe amasinthidwa ndi magetsi. Pambuyo poti O2-ion ifike pa anode ya AL metalised, imasakanikirana ndi AL kuti ipange AL2O3, yomwe pang'onopang'ono imapanga gawo loteteza AL2O3 pakapita nthawi kuti iphimbe ndikupatula cholakwikacho, motero imawonjezera kukana kwa kutetezera kwa capacitor ndikupangitsa kuti idzichiritse yokha.

N'zoonekeratu kuti mphamvu inayake imafunika kuti chipangizo choyeretsera cha organic film capacitor chidzichiritse chokha. Pali magwero awiri a mphamvu, imodzi imachokera ku magetsi ndipo inayo imachokera ku okosijeni ndi nitriding exothermic reaction ya chitsulo chomwe chili m'gawo la chilema, mphamvu yomwe imafunika kuti munthu adzichiritse nthawi zambiri imatchedwa mphamvu yodzichiritsira yokha.

 
Kudzichiritsa ndi chinthu chofunikira kwambiri pa ma capacitor a filimu yachitsulo ndipo ubwino wake ndi waukulu. Komabe, pali zovuta zina, monga kuchepa pang'onopang'ono kwa mphamvu ya capacitor yomwe imagwiritsidwa ntchito. Ngati mphamvuyo ikugwira ntchito ndi kudzichiritsa kwambiri, izi zipangitsa kuti mphamvu yake ndi kukana kutentha zichepe kwambiri, kuwonjezereka kwakukulu kwa ngodya yotayika komanso kulephera kwachangu kwa capacitor.

Ngati muli ndi chidziwitso cha zinthu zina zokhudza mphamvu ya ma capacitor a filimu opangidwa ndi zitsulo, chonde tiuzeni.
