Nekuwedzera kuri kuramba kuchiita kudiwa kwesimba idzva, zvinotarisirwa kuti musika weChina wemagetsi ekugadzira mafirimu uchapinda munguva yekukura kukuru zvakare mumakore mashoma anotevera. Firimu rePolypropylene, iro riri chinhu chikuru chemagetsi ekugadzira mafirimu, riri kuramba richiwedzera musiyano wekupa uye kudiwa nekuda kwekuwedzera kuri kuita kudiwa uye kuburitswa zvishoma nezvishoma kwesimba rekugadzira. Chinyorwa chevhiki rino chichatarisa zvinhu zvikuru zvemagetsi ekugadzira mafirimu - firimu repolypropylene (firimu rePP).

Mukupera kwema1960, firimu remagetsi repolypropylene rakava rimwe remafirimu matatu makuru emagetsi nekuda kwehunhu hwaro hwakasiyana hwemagetsi uye hwekugadzirisa uye mashandiro akanaka emutengo, uye raishandiswa zvakanyanya muindasitiri yemagetsi emagetsi. Mukutanga kwema1980, kugadzirwa kwemacapacitor efirimu repolypropylene resimbi kwakanga kwatotanga munyika dzakabudirira muEurope neAmerica, nepo China ichiri muchikamu chekugadzirwa kwemacapacitor efirimu repolypropylene resimbi. Kuburikidza nekuunzwa kwetekinoroji yekugadzira macapacitor efirimu repolypropylene resimbi uye zvishandiso zvakakosha, ndipo patakazova nemacapacitor efirimu repolypropylene resimbi mupfungwa chaiyo.

Ngatizivei mashandisirwo efirimu repolypropylene mumacapacitor efirimu uye mamwe mashoko mapfupi. Macapacitor efirimu repolypropylene ndeekirasi yecapacitor yefirimu reorganic, nzira yaro ifirimu repolypropylene, electrode ine mhando yesimbi uye mhando yefirimu resimbi, pakati pecapacitor pakaputirwa ne epoxy resin kana kuti yakavharirwa mupurasitiki nesimbi. Iyo capacitor yepolypropylene yakagadzirwa neelectrode yefirimu resimbi inonzi metallized polypropylene film capacitor, iyo inowanzozivikanwa secapacitor yefirimu. Polypropylene film ipurasitiki inogadzirwa nepolymerizing propylene. Inowanzova yakakora, yakasimba, uye ine simba rakawanda rekusunga, uye inogona kushandiswa kumafirimu egreenhouse, mabhegi anotakura mutoro, nezvimwewo. Polypropylene ipolymer isina chepfu, isina hwema, isina kuravira, chena ine mukaka, ine crystalline yakawanda ine density ye 0.90-0.91g/cm³ chete. Ndiyo imwe yemhando dzakareruka dzepurasitiki dzese dziripo. Yakasimba zvakanyanya kumvura, mwero wekunyudzwa kwemvura mumvura i0.01% chete, huremu hwemamorekuru hunosvika 80,000-150,000.

Firimu rePolypropylene ndiro chinhu chikuru chemacapacitor efirimu. Nzira yekugadzira firimu inonzi metallized film, iyo inogadzirwa ne vacuum vaporizing simbi yakatetepa pafirimu repurasitiki se electrode. Izvi zvinogona kuderedza huwandu hwe capacitor unit capacitor, saka firimu iri nyore kugadzira ma capacitor madiki, ane simba rakawanda. Pamusoro pe firimu recapacitor rinonyanya kusanganisira base film, metal foil, waya, outer packaging, nezvimwewo. Pakati pazvo, base film ndiyo chinhu chikuru chemarara, uye musiyano wezvinhu uchaita kuti ma capacitor efirimu aratidze mashandiro akasiyana. Base film inowanzo kamurwa kuita polypropylene ne polyester. Kana base film yakakora, voltage yakakwira, uye zvinopesana, voltage yainogona kumira yakaderera. Base film ndiyo electrical grade electronic film, sezvo dielectric yema capacitor efirimu ndiyo inonyanya kukosha kumusoro, iyo inosarudza mashandiro ema capacitor efirimu uye inotora 60%-70% yemutengo wezvinhu. Panyaya yemusika, vagadziri vekuJapan vane hutungamiriri hwakajeka mukugadzira macapacitor emhando yepamusoro emafirimu, Toray, Mitsubishi neDuPont dziri ivo vatengesi vemafirimu emhando yepamusoro pasi rose.

Mafirimu emagetsi epolypropylene emotokari itsva dzinoshandisa simba, photovoltaic uye simba remhepo anonyanya kuunganidzwa pakati pe2 ne4 microns, uye kugona kwekugadzira kwaderedzwa neanopfuura hafu munguva imwe chete zvichienzaniswa ne6 kusvika 8 microns yemidziyo yemumba yakajairika, zvichikonzera kudzikira kukuru kwekugadzirwa kwese uye kudzoserwa kwekuwanikwa kwemusika nekudiwa. Kuwanikwa kwefirimu remagetsi repolypropylene kuchave kushoma mumakore anotevera. Parizvino, michina mikuru yefirimu remagetsi repasi rose repolypropylene inogadzirwa muGermany, Japan nedzimwe nyika, uye kutenderera kwekuvaka kwesimba idzva kwemwedzi 24 kusvika 40. Pamusoro pezvo, zvinodiwa zvekushanda kwemafirimu matsva emotokari zvine simba zvakakwirira, uye makambani mashoma chete anokwanisa kudzikamisa kugadzirwa kwemafirimu matsva emagetsi epolypropylene, saka pasi rose, hapazovi nekukwanisa kwekugadzira mafirimu matsva epolypropylene muna 2022. Kumwe kudyara mari mumitsetse yekugadzira kuri kutaurwa. Nokudaro, pangave nemukana mukuru wesimba reindasitiri yese gore rinouya.
