M'nkhani yapitayi tinayang'ana pa imodzi mwa njira ziwiri zosiyana zodzichiritsira muzitsulo za filimu za metalised: kutulutsa kudzichiritsa, komwe kumadziwikanso kuti kuchiritsa kwamphamvu kwambiri.M'nkhaniyi tiona mtundu wina wa kudzichiritsa, electrochemical kudzichiritsa, komanso nthawi zambiri amatchedwa low-voltage kudzichiritsa.

Kudzichiritsa kotereku nthawi zambiri kumachitika mu aluminium metalised filimu capacitors pamagetsi otsika.Njira yodzichiritsa yokha ili motere: ngati pali vuto mu filimu ya dielectric ya capacitor ya metalised filimu, voteji itatha kuwonjezeredwa ku capacitor (ngakhale votejiyo ili yochepa kwambiri), padzakhala kutayikira kwakukulu. panopa kudzera chilema, chimene chimasonyezedwa ngati kutchinjiriza kukana capacitor ndi otsika kwambiri kuposa mtengo wotchulidwa mu mikhalidwe luso.Mwachiwonekere, pali mafunde a ionic komanso mafunde amagetsi omwe akutuluka.Chifukwa mitundu yonse ya mafilimu achilengedwe imakhala ndi kuchuluka kwa mayamwidwe amadzi (0.01% mpaka 0.4%) komanso chifukwa ma capacitor amatha kukhala ndi chinyezi panthawi yopanga, kusungirako ndikugwiritsa ntchito, gawo lalikulu la ionic pano lidzakhala O2- ndi H-ion. mafunde obwera chifukwa cha madzi opangidwa ndi electrolysed.O2-ion ikafika ku AL metalised anode, imaphatikizana ndi AL kuti ipange AL2O3, yomwe pang'onopang'ono imapanga wosanjikiza wa AL2O3 pakapita nthawi kuti aphimbe ndikupatula chilemacho, motero amawonjezera kukana kwa capacitor ndikukwaniritsa kudzichiritsa.

Ndizodziwikiratu kuti kuchuluka kwa mphamvu kumafunikira kuti mukwaniritse kudzichiritsa nokha kwa metalised organic film capacitor.Pali magwero awiri a mphamvu, mmodzi amachokera ku magetsi ndipo winayo amachokera ku okosijeni ndi nitriding exothermic reaction ya zitsulo mu gawo lachilema, mphamvu yofunikira yodzichiritsa nthawi zambiri imatchedwa mphamvu yodzichiritsa yokha.

 
Kudzichiritsa nokha ndi chinthu chofunikira kwambiri cha ma capacitor a filimu opangidwa ndi zitsulo ndipo phindu lomwe limabweretsa ndi lalikulu.Komabe, pali zovuta zina, monga kuchepa kwapang'onopang'ono kwa mphamvu ya capacitor yomwe imagwiritsidwa ntchito.Ngati mphamvu ikugwira ntchito ndi kudzichiritsa kochuluka, kumayambitsa kuchepa kwakukulu kwa mphamvu zake ndi kukana kutchinjiriza, kuwonjezeka kwakukulu kwa mbali yotayika komanso kulephera kwachangu kwa capacitor.

Ngati muli ndi chidziwitso pazinthu zina za kudzichiritsa nokha kwa metalised film capacitor, chonde kambiranani nafe.
