Ukuze kuhlangatshezwane nesidingo Sokuvuthwa Kwamafutha Aphansi ngaphansi komthetho we-CARB kanye ne-EPA ezimakethe zaseMelika, i-FKM isetshenziswa kabanzi ekwenzeni i-CARB ne-EPA ehambisana ne-Low Permeation Fuel Line Hose ekusebenziseni i-ATV, Izithuthuthu, Amajeneretha, Izinjini Ezingekho Emgwaqweni. , Izinjini Zasolwandle, Imishini Yengadi, Izinsiza Zamandla Zangaphandle, njll.
Okokuqala, ukuhlukaniswa kwe-Fluoro Rubber (FKM)
Irabha ye-Fluoro 26: I-Vinylidene fluoride - hexafluoropropylene, Viton A, No. 2 fluororubber
I-Fluororubber 246: I-Vinylidene fluoride - i-tetrafluoroethylene - i-hexafluoropropylene, i-Viton B, i-rubber engu-3 ye-fluoro
Irabha ye-Fluoro 23: I-Vinylidene fluoride - trifluorochloropropylene, no.1 i-fluororubber
Irabha ye-Vinylidene fluoride: Vinylidene fluoride - tetrafluoroethylene -PMVE- sulfide point monomer, Viton GLT
Irabha yePerfluoroether: Tetrafluoroethylene -PMVE- perfluorosulfide point monomer, Kalrez
I-Tetrafluoroethylene - i-hydrocarbon propylene, i-Aflas
Irabha ye-fluorine ne-silicone
I-Phosphone-nitrile fluororubber
Irabha yeNitrofluoro
Okwesibili, i-FKM icubungula izinto ezibalulekile
I-Mooney viscosity, isivinini sokuphulukisa, ukuphepha kwe-coke, uketshezi, ukudiliza
Okwesithathu, ubuchwepheshe obujwayelekile be-FMK bokucubungula
1. Ukubunjwa komjovo: ukusetshenziswa kwale nqubo yerabha ye-fluorine kungasebenzisa i-Mooney viscosity ephansi kanye ne-Mooney viscosity ephakathi (20-60mV), ukuphepha okuhle kwe-coke kanye nomkhiqizo wejubane lokuvuvukala.
2), I-Injection Pressure: ukusetshenziswa kwale nqubo yenjoloba ye-fluorine kungasebenzisa i-Mooney viscosity ephansi kanye ne-Mooney viscosity ephakathi (20-60mV), uhlobo oluhle lokuphepha oluvuthayo, ukuze lingakhiqizi i-coke ngesikhathi sokujova.
3. ukubunjwa kwepuleti: ukusetshenziswa kwale nqubo yenjoloba ye-fluorine kungasebenzisa i-Mooney viscosity ephezulu (50-90MV), uhlobo lwesivinini se-vulcanization.
4. ukubunjwa kwe-extrusion: ukusebenzisa le nqubo yerabha ye-fluorine kungasebenzisa i-Mooney viscosity ephansi (20-40MV), uphawu oluhle lokuphepha kwe-coke.Ukucubungula ingculazi kungasetshenziswa ezimweni eziningi ukuze kuthuthukiswe uketshezi kanye nokuqedwa kwendawo.
5. ukubunjwa kokugqoka: i-viscosity yesisombululo inqunywa yi-solvent ekhethiwe kanye nenani lokugcwalisa.Ukuzinza (impilo yesitoreji) yesixazululo inkinga yokuqala okufanele icatshangelwe.
-- Izigaba ezimbili: Irabha ekugcineni ifakwa engozini ngezigaba ezimbili ukuze isebenze kahle.Isimo se-vulcanization sezigaba ezimbili esijwayelekile ngu-230℃ @ 24h.Kodwa-ke, isikhathi kanye nezinga lokushisa kwesigaba sesibili se-vulcanization kuyahlukahluka ngomkhiqizo, inqubo kanye nezindleko.Kwezinye izinhlelo zokusebenza.Izigaba ezimbili ze-vulcanization zingasatshalaliswa.
Okwesine, Inzuzo Yerabha Ehlukile
Ukuma Okuhlukile kwe-CARB ne-EPA Fuel Line Hose
Ukuma Okuhlukile kwe-CARB ne-EPA Fuel Line Hose
Eyesihlanu, ukusetshenziswa kwe-FKM
Izimboni zezimoto, i-aerospace, petrochemical kanye nemishini yizimboni ze-fluororubber ezisetshenziswa kakhulu, kanye no-60% ~ 70% werabha ye-fluoro esetshenziswa embonini yezimoto.
Imithethonqubo efanelekile yezimoto izoba nomthelela omkhulu ekusetshenzisweni kwe-fluororubber.Inselele enkulu yomkhakha wokukhiqiza we-fluoroelastomer ukusiza imboni yezimoto ukuthi ithole izinto zokungena ezingcono neziphansi ukuze ihlangabezane namazinga amasha aqinile wokuphuma kwezimoto.Isistimu yesibaseli kanye nabakhiqizi beNjini sekuyisikhathi eside begxile kuma-fluoroelastomers ukuze uthole uphethiloli kanye ne-driveline efana namaHhosi Amafutha, Ulayini Wezibaseli, Izimbobo zenjini kanye neHose ukumelana nowoyela, i-EPA & CARB Certificated Fuel Line/Fuel Hose, Low Permeation(≦2.5g/m2/usuku ) Ukusetshenziswa kwe-Fuel Line/Fuel Hose ku-ATV, Izithuthuthu, Amajeneretha, Izinjini Ezingekho Emgwaqweni, Izinjini Zasolwandle, Imishini Yengadi, Izisetshenziswa Zamandla Zangaphandle, Izimoto.ect.
