Okugumira ebbugumu Okugumira woyiro Okugumira mmotoka Fluoroelastomer

 Enzimba ya molekyu & Enzikiriziganya y’enkola

Omugongo gwa polimeeri guzimbibwa okuva mu  vinylidene fluoride (VDF) , hexafluoropropylene (HFP)  ne  tetrafluoroethylene (TFE)  mu mugerageranyo omutuufu ogwa 40/30/30, ekivaamu  ekirungo kya fluorine ekisinga obunene ekisangibwa mu FKM ey’ettunzi . Matrix eno eya fluorocarbon enzito ekola  ekiziyiza ky’amasoboza ag’okungulu aga wansi ennyo (< 18 mN m−1)  ekigoba amafuta agatali  ga polar hydrocarbons , polar ester oils ,  n’ebirungo ebikola ennyo  nga methanol oba biodiesel. Enkola ya  peroxide-scavenging bisphenol-AF cure system  emalawo brittle post-cure embrittlement, n’ewa  > 20 MPa amaanyi g’okusika n’amaanyi  g’okukutuka  35 kN m−1  ne bwe wabaawo  1,000 h @ 200 °C . Ekivaamu kye kirungo  ekiwangaala okusinga silikoni ne HNBR 3×  mu nvulopu y’emu ey’ebbugumu ate nga kikuuma  < 3 % volume swell mu IRM903 reference oil.

Spectrum y'okukozesa mmotoka

Enkola za Turbocharger

• Emikutu gy’empewo egy’oku chajingi  n’ebiwujjo  bya vvaalu  ebifuuwa ebilaba  entikko za 260 °C  wansi w’esannyalazo enzibu.

• Wastegate actuator seals  ezigumira  amafuta aga synthetic 5W-30 + enfuufu.

Amafuta & SCR Circuits

• Empeta za O ezikuba empiso obutereevu  ezisiba  amafuta ga dizero aga bbaala 350.

• AdBlue (DEF) injector seals  nga  FKM-65B20 ’s  low extractables  ziziyiza okufuuka crystallization fouling.

Yingini & Transmission

• Gaasikiti ezinyogoza amafuta  nga ziteekeddwa ku  mafuta ga 150 °C + okukankana.

• E-motor housing grommets  mu PHEVs nga  omukka gwa electrolyte  gulumba elastomers eza standard.

Chassis ne Bbuleeki

• ESP hydraulic accumulator bladders  nga zeetaaga  < 0.1 % okuyingira kw’amafuta.

• Ebiwujjo ebiwanirira empewo  ebiziyiza  ozone, omunnyo gw’oku nguudo n’amazzi ga buleeki.
