Chiyembekezo cha Msika wa Ma Filimu Ochepa Ndiabwino, Kuyendetsa Kukula kwa Msika Kufunika Kwa Mafilimu Ochepa a Ma Capacitors

Polyester yomwe imagwiritsidwa ntchito nthawi zambiri imakhala yamagetsi amtundu wa polyethylene terephthalate (polyester yamagetsi yamagetsi, PET), yomwe imakhala ndi mawonekedwe amagetsi apamwamba kwambiri, kulimba kwamphamvu komanso mphamvu zamagetsi zamagetsi.

Filimu ya capacitor imatanthawuza filimu ya pulasitiki yamagetsi yamagetsi yomwe imagwiritsidwa ntchito ngati dielectric material for film capacitors, yomwe ili ndi zofunikira zapadera pamagetsi amagetsi, monga mphamvu ya dielectric yapamwamba, kutayika kochepa, kukana kutentha kwapamwamba, crystallinity yapamwamba ndi zina zotero. Ma capacitor opyapyala opangidwa ndi filimu yopyapyala ngati zida zopangira ali ndi mwayi wokhala ndi mphamvu yokhazikika, kutayika kochepa, kukana kwambiri kwamagetsi, kukana kwamphamvu kwambiri, mawonekedwe abwino pafupipafupi komanso kudalirika kwakukulu, ndipo amagwiritsidwa ntchito kwambiri pamagetsi, zida zapanyumba, kulumikizana, mphamvu yamagetsi, kuyatsa kwa LED, mphamvu zatsopano ndi zina.

Makanema a capacitor nthawi zambiri amakhala a polypropylene ndi poliyesitala ngati zida zopangira, zomwe polypropylene nthawi zambiri imakhala yamagetsi amtundu wa homopolymer polypropylene (high gauge homopolymer PP), yokhala ndi chiyero chambiri, kukana kutentha kwambiri, kutchinjiriza, kukhazikika kwamankhwala, kukana mphamvu ndi zina. Polyester yomwe imagwiritsidwa ntchito nthawi zambiri imakhala yamagetsi amtundu wa polyethylene terephthalate (polyester yamagetsi yamagetsi, PET), yomwe imakhala ndi mawonekedwe amagetsi apamwamba kwambiri, kulimba kwamphamvu komanso mphamvu zamagetsi zamagetsi. Kuphatikiza apo, zinthu za filimu ya capacitor zimaphatikizansopo polystyrene yamagetsi yamagetsi, polycarbonate, polyimide, polyethylene naphthalate, polyphenylene sulfide, ndi zina zambiri, ndipo kuchuluka kwa zinthu izi ndizochepa kwambiri.

M'zaka zaposachedwa, ndi kusintha kwa mphamvu ya sayansi ndi luso lamakono la China, mabizinesi ambiri adutsa pang'onopang'ono zolepheretsa kukula kwa mafakitale, panthawi imodzimodziyo, kufunika kwa filimu ya capacitor ku China kukupitiriza kukula, boma lakhazikitsanso ndondomeko zolimbikitsa ndikuthandizira chitukuko cha mafakitale cha filimu ya capacitor ndi ntchito zake. Pokopeka ndi zomwe zikuyembekezeka pamsika komanso motsogozedwa ndi mfundo zolimbikitsa, mabizinesi omwe alipo akupitiliza kukulitsa masikelo opangira ndikuyala mizere yopangira mafilimu opangira ma capacitor, ndikupititsa patsogolo kuchulukira kwaukadaulo wopanga makanema aku China. Malinga ndi "Research Report on the Market Monitoring and future Development Prospects of China's Capacitor Film Industry mu 2022-2026" yotulutsidwa ndi Xinsijia Industry Research Center, kuyambira 2017 mpaka 2021, kuchuluka kwamakampani opanga mafilimu aku China kudakwera kuchokera matani 167,000 mpaka 2000.
