Ngokunyuka okuqhubekayo kwemfuno yamandla amatsha, kulindeleke ukuba imakethi yaseTshayina yefilimu ye-capacitor ingene kwixesha lokukhula okuphezulu kwakhona kwiminyaka embalwa ezayo.Ifilimu yePolypropylene, eyona nto ingundoqo yee-capacitors zefilimu, iyaqhubeka nokwandisa unikezelo kunye ne-gap yemfuno ngenxa yokwanda ngokukhawuleza kwemfuno kunye nokukhululwa okucothayo komthamo wemveliso.Inqaku lale veki liza kujonga izinto ezingundoqo zefilimu capacitors- ifilimu ye-polypropylene (ifilimu ye-PP).

Ngasekupheleni kweminyaka yoo-1960, ifilimu yombane ye-polypropylene yaba yenye yeefilimu ezintathu ezinkulu zombane ngenxa yeempawu zayo ezizodwa zombane kunye neempawu zokusetyenzwa kunye nokusebenza kweendleko ezigqwesileyo, kwaye yayisetyenziswa ngokubanzi kwishishini le-capacitor yamandla.Ekuqaleni kweminyaka yee-1980, ukuveliswa kwee-capacitors zefilimu ezine-polypropylene sele kuqalile kumazwe aphuhlileyo eYurophu naseMelika, ngelixa i-China yayisekwinqanaba lophuhliso lwee-metallised polypropylene film capacitors.Kuphela ngokungeniswa kwe-metallised polypropylene film capacitor technology kunye nezixhobo eziphambili siye sane-metallised polypropylene film capacitors ngokwenyani.

Makhe siqhelane nokusetyenziswa kwefilimu ye-polypropylene kwii-capacitors zefilimu kunye nesingeniso esifutshane.I-polypropylene film capacitors iyingxenye yeklasi ye-organic film capacitor, i-medium yayo yifilimu ye-polypropylene, i-electrode inohlobo lwe-metal host kunye nohlobo lwefilimu yensimbi, ingundoqo ye-capacitor ihlanganiswe ne-epoxy resin okanye ifakwe kwiplastiki kunye necala lensimbi.I-polypropylene capacitor eyenziwe nge-electrode yefilimu yensimbi ibizwa ngokuba yi-metallized polypropylene film capacitor, eyaziwa ngokuba yifilimu capacitor.Ifilimu yePolypropylene yintlaka ye-thermoplastic eyenziwe nge-polymerizing propylene.Idla ngokuba ngqindilili, yomelele, kwaye inamandla aphezulu okuqina, kwaye ingasetyenziselwa iifilimu zegreenhouse, iingxowa ezithwele umthwalo, njl. njl. Ipolypropylene ayiyotyhefu, ayinavumba, ayinancasa, imhlophe yobisi, ipholima eyikristale kakhulu enoxinano kuphela. 0. 90-0.91g/cm³.Yenye yezona ntlobo zikhaphukhaphu kuzo zonke iiplastiki ezikhoyo.Uzinzile ngokukodwa kumanzi, izinga lokufunxa amanzi emanzini li-0. 01% kuphela, ubunzima be-molecular malunga ne-80,000-150,000.

Ifilimu yePolypropylene iyona nto ingundoqo yefilimu capacitors.Indlela yokwenziwa kwefilimu capacitor ibizwa ngokuba yifilimu enesinyithi, eyenziwa ngokufunxa umaleko obhityileyo wesinyithi kwifilimu yeplastiki njenge electrode.Oku kunokunciphisa umthamo womthamo weyunithi ye-capacitor, ngoko ke ifilimu ilula ukwenza i-capacitors encinci, ephezulu.Ukunyuka kwe-capacitor yefilimu ngokuyinhloko kubandakanya isiseko sefilimu, i-foil yensimbi, ucingo, ukupakishwa kwangaphandle, njl.Ifilimu yesiseko ihlukaniswe ngokubanzi kwi-polypropylene kunye ne-polyester.Ukuqina kwefilimu yesiseko, iphezulu i-voltage enokumelana nayo, kwaye ngokuchaseneyo, i-voltage ephantsi inokumelana nayo.Ifilimu yesiseko yifilimu ye-elektroniki yebakala lombane, njengoko i-dielectric ye-capacitors yefilimu iyona nto ibaluleke kakhulu enyukayo, emisela ukusebenza kwee-capacitors zefilimu kwaye ithatha i-60% -70% yeendleko eziphathekayo.Ngokubhekiselele kwipateni yemarike, abavelisi baseJapan banesikhokelo esicacileyo kwimathiriyeli ekrwada ye-high-end capacitors ifilimu, kunye neToray, iMitsubishi kunye neDuPont zingababoneleli befilimu abakumgangatho ophezulu wehlabathi.

Iifilimu zepolypropylene zombane zezithuthi zamandla amatsha, i-photovoltaic kunye namandla omoya zigxininiswe ikakhulu phakathi kwe-2 kunye ne-4 microns, kwaye umthamo wemveliso uncitshiswe ngaphezu kwesiqingatha ngexesha elifanayo xa kuthelekiswa ne-6 ukuya kwi-8 microns kwizixhobo eziqhelekileyo zasekhaya, okubangele. ekwehleni okubonakalayo kwimveliso epheleleyo kunye nokuguqulwa kobonelelo lwemarike kunye nemfuno.Ukunikezelwa kwefilimu ye-polypropylene yombane iya kulinganiselwa kwiminyaka ezayo.Okwangoku, izixhobo eziphambili zefilimu ye-polypropylene yomhlaba jikelele ziveliswa eJamani, eJapan nakwamanye amazwe, kwaye umjikelezo wokwakhiwa komthamo omtsha kwiinyanga ezingama-24 ukuya kwe-40.Ukongezelela, iimfuno zokusebenza kweefilimu zemoto zamandla amatsha ziphezulu, kwaye iinkampani ezimbalwa kuphela ziyakwazi ukuzinzisa ukuveliswa kwemveliso yamandla amatsha eefilimu ze-polypropylene zombane, ngoko kwihlabathi jikelele, akuyi kubakho amandla okuvelisa ifilimu ye-polypropylene kwi-2022. Olunye utyalo-mali kwi imigca yemveliso iphantsi kothethathethwano.Ke ngoko, kunokubakho umsantsa omkhulu womthamo kulo lonke ishishini kunyaka ozayo.
