Izici |
Inokumelana okuhle kakhulu namazinga okushisa aphezulu naphansi, ukumelana nokugqwala kwamakhemikhali aqinile, ukumelana kahle nokuguga kanye nokumelana nesimo sezulu, ukusebenza okuthembekile kokuvala uphawu, ukumelana kahle nesethi yokucindezelwa unomphela, nokusebenza kahle kokufakwa kwe-insulation kanye nokubambezeleka komlilo. |
Izigxivizo ze-Fluororubber zinezinzuzo ezibalulekile ngaphezu kwezinye izimpawu kulezi zici ezilandelayo:
Ukumelana namakhemikhali: Ingakwazi ukumelana nemithombo yezindaba egqwala kakhulu njengama-asidi aqinile, ama-alkali aqinile, ama-oxidant aqinile, nophethiloli wendiza, kuyilapho irabha ye-nitrile ijwayele ukuguguleka emithonjeni yezindaba egqwala kakhulu.
-Ukumelana nezinga lokushisa eliphezulu: Izinga lokushisa-elide lesevisi lingafinyelela -ku-20℃kuya ku-260℃, futhi lingakwazi ukumelana nezinga lokushisa eliphakeme lesikhashana elingu-300℃. Nakuba irabha ye-silicone iphinde imelane namazinga okushisa aphezulu naphansi, ukuzinza kwayo kwamakhemikhali emazingeni okushisa aphezulu akufani naleyo ye-fluororubber.
Ukumelana nokuguga: Iguga kancane ezindaweni ezifana ne-ozone, imisebe ye-ultraviolet, kanye nomswakama, futhi inempilo ende yesevisi, ephakeme kunejubane lokuguga lerabha ye-chloroprene nezinye izinto endaweni yangaphandle.
Isethi yokuminyanisa encane: Ngaphansi kwesenzo-sesikhathi eside sezinga lokushisa eliphezulu nokucindezela okuphezulu, isengakwazi ukugcina ukunwebeka okuhle nokusebenza kokuvala. Irabha ye-Nitrile nezinye zinamasethi amakhulu okucindezela ngaphansi kwezimo zokusebenza ezifanayo.
Inezinhlobonhlobo zezimo zokusebenza ezisebenzayo: Ingasebenza ngokuzinza ezimeni zokusebenza ezinzima kakhulu njengemikhumbi yokusabela ngamakhemikhali, izinjini ze-aero, namathuluzi e-downhole petroleum. Ezinye izingxenye zokuvala zithola kunzima ukuhlangabezana nezimo eziningi ezimbi kakhulu ngesikhathi esisodwa.
