DuPont yakagadzira tekinoroji ine patent yekubatanidza uye kugadzirisa efluoropolymer foam resin.Kuita kwefuro kunosanganisira kuenderera mberi kwejekiseni regesi senitrogen rakananga muextruder yakazadzwa neresin yakanyungudutswa.Iyo yakanyatsogadzirwa extruder screw inowanzo shandiswa kugadzira iyo polymer gasi musanganiswa ine inert nucleating package iri muresin kubatsira kusimudzira sero kukura.Mafuro anosvika 60% voids akaratidzwa kuburikidza nekushandiswa kwemaitiro aya.
Zvikumbiro zveMelt Processable Perfluorinated Resins
FEP uye PFA perfluorinated resins ine melt viscosities yakaderera zvakakwana kuti igadziriswe mu melt extruders.Pamusoro pezvo, FEP nePFA zvakanyatsokodzera kuburitsa furo uku ichichengetedza yakaderera dielectric kugara uye yakaderera dissipation zvinhu, zvese zvinodiwa kune akamonyoroka maviri uye coaxial tambo insulation.
Tambo dze data dzinoshandiswa mukufambiswa kwezviratidzo zvemagetsi mumhando dzakasiyana siyana uye maapplication.Izvo zvakakosha zvemagetsi zvinodikanwa kune aya tambo zvinosanganisira yakaderera dielectric nguva dzose uye yakaderera dissipation chinhu.Izvi zvivakwa zvinogona kukwidziridzwa nekupupa iyo insulation.Zvichienderana neresin inoshandiswa, tambo dzine furo insulation dzinobvumira tambo miniaturization, kudzikisa huremu hwechigadzirwa chekupedzisira, uye kutapurirana kwemagetsi akajeka emhando yepamusoro pakumhanya kwechiratidzo.
Tambo dzine furo dzakagadzirwa kubva kuDuPont fluoropolymer resin dzave nemukurumbira zvakanyanya mukugadzira komputa uye kuisirwa network masisitimu.Matambo akagadzirwa neFEP kana PFA ane yakaderera-moto uye yakaderera-utsi hunhu.Tambo idzi dzinogona kufambiswa nemumaplenum nemamwe madhiri ekufambisa mhepo, zvichideredza kudiwa kwekuiswa kunodhura kwepombi yemagetsi.
Chimiro uye Zvivakwa zveFluoropolymers
Kuwanikwa kwePTFE neDuPont kwakaitika muma1930, asi panguva iyoyo, resin itsva yeperfluorinated yaisakwanisa kunyungudutswa.Imwezve tsvakiridzo yakaitwa neDuPont mukugadziridzwa kwepolymer architecture yakatungamira mukugadzirwa kweakatevedzana anonyunguduka anogona kunyunguduka mafluoropolymers akadai seFEP, PFA, uye ETFE, ichisimbisa DuPont semutungamiri wenyika mukutsvagisa fluoropolymer.
Iko kugona kunyungudusa extrude mapolymers aya, akasanganiswa nehunhu hwakadai seyepasi dielectric inogara uye kushomeka kwemoto yakaita FEP nePFA inonyatso kuenderana newaya uye tambo yekushandisa.
