Nekuwedzera kuri kuita simba idzva kudiwa, zvinotarisirwa kuti musika weChina wemufirimu capacitor uchapinda munguva yekukura yakakwira zvakare mumakore mashoma anotevera.Polypropylene firimu, iyo yakakosha zvinhu zvemafirimu capacitors, iri kuenderera mberi nekuwedzera iyo yekugovera uye yekuda gaka nekuda kwekukurumidza kuwedzera kwekudiwa uye kunonoka kuburitswa kwesimba rekugadzira.Chinyorwa chesvondo rino chichatarisa pane zvakakosha zvemufirimu capacitors- polypropylene firimu (PP firimu).

Mukupera kwema1960, firimu remagetsi repolypropylene rakave rimwe remafirimu matatu makuru emagetsi nekuda kwekusiyana kwemagetsi nekugadzirisa maitiro uye kuita kwemutengo wakanaka, uye raishandiswa zvakanyanya muindasitiri yemagetsi capacitor.Mukutanga kwema1980, kugadzirwa kwemetallized polypropylene film capacitors kwakange kwatotanga munyika dzakabudirira muEurope neAmerica, uku China yaive ichiri mudanho rekusimudzira remetallized polypropylene film capacitors.Kuburikidza chete nekuunzwa kwemetallicized polypropylene film capacitor kugadzira tekinoroji uye kiyi midziyo yatakaita metallized polypropylene film capacitors mupfungwa chaiyo.

Ngatizivei nezvekushandiswa kwepolypropylene firimu mumafirimu capacitors uye imwe sumo pfupi.Polypropylene film capacitors ndeye organic film capacitor class, yepakati i polypropylene film, electrode ine metal host type uye metal film type, musimboti wecapacitor wakaputirwa ne epoxy resin kana kuvharirwa mupurasitiki nesimbi kesi.Iyo polypropylene capacitor yakagadzirwa nesimbi firimu electrode inonzi metallized polypropylene film capacitor, iyo inowanzozivikanwa sefirimu capacitor.Polypropylene film is thermoplastic resin yakagadzirwa ne polymerizing propylene.Kazhinji yakakora, yakasimba, uye ine simba repamusoro, uye inogona kushandiswa ku greenhouse films, mabhegi anotakura zvinhu, etc. Polypropylene is a non-chepfu, hainhuhwi, isinganakidze, milky white, very crystalline polymer ine density of only. 0. 90-0.91g/cm³.Ndiyo imwe yemhando dzakareruka pamapurasitiki ese aripo.Inonyanya kugadzikana kumvura, chiyero chemvura mumvura inongova 0. 01%, molecular uremu hunenge 80,000-150,000.

Polypropylene firimu ndiyo yakakosha zvinhu zvemufirimu capacitors.Iyo nzira yekugadzira yefirimu capacitor inonzi metallized film, iyo inogadzirwa nevacuum vaporizing chidimbu chesimbi papurasitiki firimu se electrode.Izvi zvinogona kuderedza vhoriyamu ye capacitor unit simba, saka iyo firimu iri nyore kuita diki, yakakwirira-capacitor capacitors.Kukwidza kwemufirimu capacitor kunonyanya kusanganisira firimu rekutanga, simbi foil, waya, kunze kwekuputira, nezvimwewo. Pakati pavo, firimu rekutanga ndiro raw material, uye kusiyana kwezvinhu kuchaita kuti mafirimu capacitors aratidze kushanda kwakasiyana.Iyo firimu yepasi inowanzo kupatsanurwa kuita polypropylene uye polyester.Iyo yakakora iyo base firimu iri, iyo yakakwirira iyo voltage inogona kumira, uye zvinopesana, iyo yakaderera voltage iyo inogona kumira.Base firimu ndiyo yemagetsi giredhi remagetsi firimu, sezvo dielectric yefirimu capacitors ndiyo inonyanya kukosha kumusoro kwemvura mbishi, iyo inotaridza kuita kwemafirimu capacitor uye inotora 60% -70% yemutengo wezvinhu.Panyaya yemaitiro emusika, vagadziri veJapan vane kutungamira kwakajeka muzvigadzirwa zvemafirimu epamusoro-ekupedzisira capacitor, Toray, Mitsubishi neDuPont vari ivo vepamusoro mhando yepasi rose vatengesi vemafirimu.

Magetsi polypropylene mafirimu emagetsi matsva emagetsi, photovoltaic uye simba remhepo anonyanya kuiswa pakati pe 2 ne 4 microns, uye huwandu hwekugadzira hwakaderedzwa neinodarika hafu munguva imwe chete yenguva zvichienzaniswa ne6 kusvika ku8 microns yemidziyo yakajairika yemumba, zvichikonzera. mukuderera kukuru mukugadzirwa kwese uye kudzoreredzwa kwemusika wekupa uye kudiwa.Kupihwa kwemagetsi polypropylene firimu kuchave kushoma mumakore anotevera.Parizvino, iyo huru michina yepasi rose yemagetsi polypropylene firimu inogadzirwa muGermany, Japan nedzimwe nyika, uye kutenderera kwekuvaka kwehunyanzvi hutsva ndeye 24 kusvika 40 mwedzi.Pamusoro pezvo, zvinodiwa zvemafirimu emagetsi emagetsi matsva zvakakwirira, uye makambani mashoma chete anokwanisa kudzikamisa kugadzirwa kwemazhinji emagetsi emagetsi epolypropylene mafirimu, saka pasi rose, hapazove nehunyanzvi hwekugadzira firimu repolypropylene muna 2022. Imwezve mari mukati mitsara yekugadzira iri pasi pekutaurirana.Naizvozvo, panogona kunge paine gomba rakakura rekugona indasitiri yese gore rinouya.
