Ngokukhula okuqhubekayo kwesidingo samandla amasha, kulindeleke ukuthi imakethe yaseChina ye-filimi capacitor iphinde ingene esikhathini sokukhula okuphezulu eminyakeni embalwa ezayo.Ifilimu ye-polypropylene, into ewumgogodla wama-capacitor amafilimu, iyaqhubeka nokwandisa igebe layo lokuhlinzekwa kanye nesidingo ngenxa yokwanda okusheshayo kwesidingo kanye nokukhululwa kancane kwamandla okukhiqiza.I-athikili yaleli sonto izobheka izinto eziwumongo zefilimu yama-capacitors- ifilimu ye-polypropylene (ifilimu ye-PP).

Ngasekupheleni kweminyaka yawo-1960, ifilimu kagesi ye-polypropylene yaba ngelinye lamafilimu amakhulu amathathu kagesi ngenxa yezici zayo ezihlukile zikagesi nokucubungula nokusebenza kwezindleko ezinhle kakhulu, futhi yasetshenziswa kabanzi embonini ye-power capacitor.Ekuqaleni kwawo-1980, ukukhiqizwa kwama-capacitor amafilimu e-polypropylene enziwe ngensimbi kwase kuqalile kakade emazweni athuthukile eYurophu naseMelika, kuyilapho i-China yayisesigabeni sokuthuthukiswa kwama-capacitor efilimu enziwe nge-polypropylene.Kuphela ngokwethulwa kobuchwepheshe bokukhiqiza ifilimu ye-polypropylene eyinsimbi kanye nemishini ebalulekile lapho saba ne-metallised polypropylene film capacitor ngomqondo wangempela.

Ake sijwayelane nokusetshenziswa kwefilimu ye-polypropylene kuma-capacitor wefilimu kanye nesingeniso esifushane.I-polypropylene film capacitor ingeyesigaba se-organic film capacitor, i-medium yayo ifilimu ye-polypropylene, i-electrode inohlobo lwe-metal host kanye nohlobo lwefilimu yensimbi, umnyombo we-capacitor usongwe nge-epoxy resin noma umbozwe ngepulasitiki nensimbi.I-polypropylene capacitor eyenziwe nge-electrode yefilimu yensimbi ibizwa nge-metallized polypropylene film capacitor, eyaziwa kakhulu ngokuthi ifilimu capacitor.Ifilimu ye-polypropylene iyi-resin ye-thermoplastic eyenziwe nge-polymerizing propylene.Ivamise ukushuba, iqine, futhi inamandla aphakeme okuqina, futhi ingasetshenziselwa amafilimu e-greenhouse, izikhwama ezithwala umthwalo, njll. I-Polypropylene ayinabo ubuthi, ayinaphunga, ayinambitheki, imhlophe njenge-milky, i-polymer ecwebe kakhulu enobuningi kuphela. 0. 90-0.91g/cm³.Ingenye yezinhlobo ezilula kakhulu kuwo wonke amapulasitiki atholakalayo.Izinzile ikakhulukazi emanzini, izinga lokumunca amanzi emanzini liyi-0.01% kuphela, isisindo samangqamuzana esingaba ngu-80,000-150,000.

Ifilimu ye-polypropylene iyisici esiyinhloko sama-capacitor wefilimu.Indlela yokukhiqiza ye-filimi capacitor ibizwa ngefilimu eyi-metalized, eyenziwa nge-vacuum vaporizing ungqimba oluncane lwensimbi kufilimu yepulasitiki njenge-electrode.Lokhu kunganciphisa umthamo weyunithi ye-capacitor, ngakho-ke ifilimu kulula ukwenza ama-capacitor amancane, aphezulu.Ukuphakama kwefilimu capacitor ikakhulukazi kuhlanganisa isisekelo sefilimu, i-foil yensimbi, intambo, ukupakishwa kwangaphandle, njll. Phakathi kwazo, ifilimu eyisisekelo iwumgogodla we-raw material, futhi umehluko wezinto ezibonakalayo uzokwenza ama-capacitor amafilimu abonise ukusebenza okuhlukile.Ifilimu yesisekelo ngokuvamile ihlukaniswe i-polypropylene ne-polyester.Uma ifilimu yesisekelo iba nkulu, kulapho i-voltage engakwazi ukumelana nayo iphakeme, futhi okuphambene nalokho, i-voltage engakwazi ukumelana nayo iyancipha.Ifilimu eyisisekelo ifilimu ye-elekthronikhi yezinga likagesi, njengoba i-dielectric yama-capacitor yefilimu iyimpahla eluhlaza ebaluleke kakhulu ekhuphuka nomfula, enquma ukusebenza kwama-filimi capacitor futhi ithatha u-60% -70% wezindleko zempahla.Mayelana nephethini yemakethe, abakhiqizi baseJapan banokuhola okucacile ezintweni zokusetshenziswa zama-capacitor amafilimu asezingeni eliphezulu, kanti iToray, iMitsubishi neDuPont zingabahlinzeki befilimu abasezingeni eliphezulu emhlabeni.

Amafilimu e-polypropylene kagesi ezimoto zamandla amasha, amandla e-photovoltaic namandla omoya agxiliswe kakhulu phakathi kwama-microns angu-2 no-4, futhi umthamo wokukhiqiza wehliswe ngaphezu kwengxenye esikhathini esifanayo uma kuqhathaniswa nama-microns angu-6 kuya kwangu-8 wezinto ezivamile zasendlini, okuholele ekutheni ekwehleni okuphawulekayo kokukhiqizwa okuphelele kanye nokuguqulwa kokuhlinzekwa kwemakethe kanye nesidingo.Ukunikezwa kwefilimu ye-polypropylene kagesi kuzonqunyelwa eminyakeni ezayo.Njengamanje, imishini eyinhloko yefilimu ye-polypropylene kagesi yomhlaba wonke ikhiqizwa eJalimane, eJapane nakwamanye amazwe, futhi umjikelezo wokwakhiwa komthamo omusha yizinyanga ezingu-24 kuya kwezingu-40.Ngaphezu kwalokho, izidingo zokusebenza zamafilimu amasha ezimoto zamandla ziphezulu, futhi izinkampani ezimbalwa kuphela ezikwazi ukuzinzisa ukukhiqizwa kwenqwaba yamafilimu amasha kagesi we-polypropylene kagesi, ngakho-ke emhlabeni jikelele, ngeke kube namandla amasha okukhiqiza ifilimu ye-polypropylene ngo-2022. Okunye ukutshalwa kwezimali ku- imigqa yokukhiqiza ingaphansi kwezingxoxo.Ngakho-ke, kungase kube negebe elikhulu lamandla embonini yonke ngonyaka ozayo.
