I-DuPont isungule ubuchwepheshe obunelungelo lobunikazi bokuhlanganiswa nokucutshungulwa kwezinsalela zegwebu ze-fluoropolymer.Inqubo yegwebu ihilela ukujova okuqhubekayo kwegesi efana ne-nitrogen ngqo ku-extruder egcwele inhlaka encibilikisiwe.Isikulufu se-extruder esiklanywe ngokukhethekile sivame ukusetshenziselwa ukudala ingxube yegesi ye-polymer ngephakheji ye-nucleating engasebenzi equkethwe ku-resin ukusiza ukukhuthaza ukukhula kweseli.Amagwebu afinyelela ku-60% we-void abonisiwe ngokusebenzisa le nqubo.
Izicelo ze-Melt Probleable Perfluorinated Resins
I-FEP kanye ne-PFA perfluorinated resins inama-viscosity ancibilikayo aphansi ngokwanele ukuze acutshungulwe kuma-extruder ancibilikayo.Ukwengeza, i-FEP ne-PFA zikufanelekela kahle ukwenza amagwebu e-extrusion ngenkathi zigcina izici zazo eziphansi ze-dielectric ezingaguquki neziphansi, zombili ezidingekayo kumapheya asontekile kanye namakhebula angama-coaxial.
Izintambo zedatha zisetshenziswa ekudluliseni amasignali e-elekthronikhi kuzilungiselelo nezinhlelo zokusebenza ezahlukahlukene.Izakhiwo zikagesi ezibalulekile ezidingekayo kulezi zintambo zihlanganisa i-dielectric constant ephansi kanye nesici esiphansi sokulahla.Lezi zakhiwo zingathuthukiswa ngokufaka amagwebu ku-insulation.Kuye nge-resin esetshenzisiwe, izintambo ezine-insulation enegwebu zivumela ukwenziwa kancane kwekhebula, ukunciphisa isisindo somkhiqizo wokugcina, kanye nokudluliselwa kwamasignali acacile kagesi wekhwalithi ephezulu ngesivinini samasignali.
Izintambo ezinegwebu ezenziwe ngama-resin e-DuPont fluoropolymer sezidume kakhulu ekukhiqizeni amakhompyutha nasekufakweni kwezinhlelo zenethiwekhi.Amakhebuli enziwe nge-FEP noma i-PFA anelangabi eliphansi kanye nezici zentuthu ephansi.Lezi zintambo zingahanjiswa kuma-plenum nakwamanye amapayipi okubamba umoya, okunciphisa isidingo sokufakwa okumba eqolo komsele kagesi.
Isakhiwo kanye Nezakhiwo ze-Fluoropolymers
Ukutholwa kwe-PTFE yi-DuPont kwenzeka ngawo-1930, kodwa ngaleso sikhathi, inhlaka entsha ene-perfluorinated yayingakwazi ukuncibilika ikhishwe.Ucwaningo olwengeziwe olwenziwa yi-DuPont ekuguqulweni kwe-polymer architecture luholele ekwakhiweni kochungechunge lwama-fluoropolymer ancibilikayo ancibilika njenge-FEP, PFA, ne-ETFE, kwaqinisa i-DuPont njengomholi womhlaba ocwaningweni lwe-fluoropolymer.
Ikhono lokuncibilika likhipha lawa ma-polymer, ahlanganiswe nezici ezifana ne-dielectric ephansi engaguquki kanye nokuvutha okuphansi kwenza i-FEP ne-PFA yafaneleka kahle ukusetshenziswa kwezintambo nezintambo.
