Irubha yeFluoro 23: IVinylidene fluoride - trifluorochloropropylene, no.I-1 fluororubber
Irabha yeVinylidene fluoride: IVinylidene fluoride - tetrafluoroethylene -PMVE- sulfide point monomer, Viton GLT
Irabha yePerfluoroether: Tetrafluoroethylene -PMVE- perfluorosulfide point monomer, Kalrez
Tetrafluoroethylene - hydrocarbon propylene, Aflas
I-Fluorine kunye nerubha ye-silicone
I-Phosphone-nitrile fluororubber
Irabha yeNitrofluoro
Okwesibini, i-FKM ilungisa izinto ezibalulekileyo
I-Money viscosity, isantya sokunyanga, ukhuseleko lwe-coke, ukuguquguquka, ukuchithwa
Okwesithathu, iteknoloji ye-FMK eqhelekileyo yokucubungula
1. I-injection molding: ukusetyenziswa kwale nkqubo yerubha ye-fluorine inokusebenzisa i-Mooney viscosity ephantsi kunye ne-mooney viscosity ephakathi (20-60mV), ukhuseleko oluhle lwe-coke kunye ne-brand ye-vulcanization yesantya.
I-2), i-Injection Pressure: ukusetyenziswa kwale nkqubo yerubha ye-fluorine ingasebenzisa i-Mooney viscosity ephantsi kunye ne-mooney viscosity ephakathi (20-60mV), i-brand yokukhusela evuthayo, ukwenzela ukuba ingavelisi i-coke kwinkqubo yokutofa.
3. ipleyiti yokubumba: ukusetyenziswa kwale nkqubo yerubha fluorine angasebenzisa Mooney viscosity eliphezulu (50-90MV), vulcanization isantya brand.
4. ukubunjwa kwe-extrusion: ukusebenzisa le nkqubo yerubha ye-fluorine inokusebenzisa i-Mooney viscosity ephantsi (20-40MV), i-brand yokhuseleko lwe-coke elungileyo.Ukusetyenzwa kwe-AIDS kunokusetyenziswa kwiimeko ezininzi ukuphucula ulwelo kunye nokuphela komphezulu.
5. ukubumba i-coating: i-viscosity yesisombululo inqunywe yi-solvent ekhethiweyo kunye nesixa sokuzalisa.Uzinzo (ubomi bokugcinwa) kwesisombululo yingxaki yokuqala ekufuneka iqwalaselwe.
-- Izigaba ezibini ze-vulcanization: Irabha ekugqibeleni ihlanjululwe kwizigaba ezibini ukwenzela ukusebenza kakuhle.Ubume bobuvulcano obunamanqanaba amabini jikelele yi-230℃ @ 24h.Nangona kunjalo, ixesha kunye nobushushu besigaba sesibini se-vulcanization siyahluka ngemveliso, inkqubo kunye neendleko.Kwezinye izicelo.Izigaba ezibini ze-vulcanization zinokukhutshwa.
Isine, i-Advanteji yeRubber eyahlukileyo
Ubume obahlukileyo be-CARB kunye ne-EPA Fuel Line Hose
Ubume obahlukileyo be-CARB kunye ne-EPA Fuel Line Hose
Isihlanu, ukusetyenziswa kwe-FKM
Imizi-mveliso yeemoto, i-aerospace, i-petrochemical kunye noomatshini ngawona mabala e-fluororubber asetyenziswa kakhulu, kunye ne-60% ~ 70% yerabha ye-fluoro esetyenziswa kushishino lweemoto.
Imimiselo efanelekileyo yeemoto iya kuba nefuthe elinzulu ekusetyenzisweni kwe-fluororubber.Owona mceli mngeni mkhulu kwishishini lemveliso ye-fluoroelastomer kukunceda ishishini leemoto lifumane izixhobo ezingcono nezisezantsi zokungena ukuze kuhlangatyezwane nemigangatho emitsha yokukhupha iimoto.Inkqubo ye-Fuel kunye nabavelisi be-Injini kudala bejolise kwi-fluoroelastomers ye-fuel kunye ne-driveline efana ne-Fuel Hoses, i-Fuel Line, i-injini yokungena kunye ne-oyile-resistant Hose, i-EPA & ne-CARB yeSiqinisekiso se-Fuel Line / i-Fuel Hose, i-Permeation ephantsi (≦2.5g/m2 / ngosuku ) Ukusetyenziswa kwe-Fuel Line / i-Fuel Hose kwi-ATV, izithuthuthu, ii-Generator, iiNjini ze-Off-Road, iiNjini zaseLwandle, oomatshini baseGadini, izixhobo zoMbane zangaphandle, ii-Automobiles.ect.
