Irabha yokwenziwa ingenye yezinto ezintathu ezinkulu zokwenziwa futhi isetshenziswa kabanzi ezicini ezihlukahlukene zemboni, ukuvikela izwe, ezokuthutha kanye nempilo yansuku zonke.Irabha yokwenziwa esebenza kahle futhi esebenzayo iwukhiye wezinto eziyisisekelo ezithuthukile ezidingekayo ekuthuthukisweni kwenkathi entsha, futhi iwumthombo wamasu obalulekile wezwe.
Izinto ezikhethekile zenjoloba zokwenziwa zibhekisela ezintweni zenjoloba ezihlukile ezintweni zenjoloba ezivamile futhi ezinezakhiwo ezikhethekile ezifana nokumelana nezinga lokushisa eliphezulu neliphansi, ukumelana nokuguga, ukumelana nokukhipha umoya, nokumelana namakhemikhali, ikakhulukazi irabha ye-nitrile eyi-hydrogenated (HNBR), i-thermoplastic vulcanizate (TPV) , Irabha ye-Silicone, irabha ye-fluorine, irabha ye-fluorosilicone, irabha ye-acrylate, njll. Ngenxa yezindawo zayo ezikhethekile, izinto zenjoloba ezikhethekile ziye zaba izinto ezibalulekile ezidingekayo ekuthuthukisweni kwamasu amakhulu kazwelonke kanye nezinkambu ezisafufusa ezifana ne-aerospace, imboni yezokuvikela kazwelonke kanye nezempi, ulwazi lwe-elekthronikhi, amandla, imvelo, nolwandle.
1. Irabha ye-nitrile enamanzi (HNBR)
Irabha ye-nitrile ene-hydrogenated iyiraba egcwele kakhulu etholwe ngokukhetha i-hydrogenating amayunithi e-butadiene ekeyini yerabha ye-nitrile ngenjongo yokuthuthukisa ukumelana nokushisa kanye nokumelana nokuguga kwerabha ye-nitrile butadiene (NBR)., isici sayo esiyinhloko ukuthi ingasetshenziswa isikhathi eside ku-150 ℃, futhi isengakwazi ukugcina izakhiwo eziphakeme zomzimba nezomshini ekushiseni okuphezulu, okungahlangabezana kahle nezidingo ezikhethekile zokumelana nokushisa okuphezulu kanye nokumelana kwamakhemikhali kwezinto ezitholakala emotweni. , i-aerospace, indawo kawoyela kanye neminye imikhakha.Izidingo, ezisetshenziswa kabanzi, njengezigxivizo zikawoyela wezimoto, izingxenye zesistimu kaphethiloli, amabhande okuhambisa izimoto, amabhokisi okumba ama-piston odaka, amarola erabha okuphrinta nendwangu, izimpawu ze-aerospace, izinto zokumuncwa ukushaqeka, njll.
2. I-Thermoplastic Vulcanisate (TPV)
Ama-Thermoplastic vulcanizates, afushanisiwe njengama-TPV, ayikilasi elikhethekile lama-thermoplastic elastomers akhiqizwa "i-dynamic vulcanization" yenhlanganisela engaqondakali ye-thermoplastics nama-elastomers, okungukuthi ukukhethwa kwesigaba se-elastomer ngesikhathi sokuncibilika kokuxutshwa ne-thermoplastic cross-linking Sexual Cross-linking.Ukwenziwa ngesikhathi esisodwa kwe-vulcanization kwesigaba senjoloba phambi kwe-agent exhumanisayo (okungenzeka ama-peroxides, ama-diamines, ama-accelerators esibabule, njll.) ngesikhathi sokuncibilika kwe-thermoplastics kuphumela ku-dynamic vulcanizate eqhubekayo ye-thermoplastic matrix eyakhiwe ngenjoloba ehlakazekile enqamula izinhlayiyana. i-vulcanization iholela ekwandeni kwe-viscosity yenjoloba, ekhuthaza ukuguqulwa kwesigaba futhi inikeza i-multiphase morphology ku-TPV.I-TPV inakho kokubili ukusebenza okufana nerabha ye-thermosetting kanye nesivinini sokucubungula se-thermoplastics, ebonakala kakhulu ekusebenzeni okuphezulu/intengo isilinganiso, idizayini evumelana nezimo, isisindo esilula, ububanzi bezinga lokushisa lokusebenza, ukucubungula okulula, ikhwalithi yomkhiqizo nokuzinza kobukhulu Futhi iphinda isetshenziswe, kabanzi. esetshenziswa ezingxenyeni zezimoto, ukwakhiwa kwamandla, izimpawu kanye neminye imikhakha.
3. Irabha ye-Silicone
Irabha ye-Silicone iwuhlobo olukhethekile lwenjoloba yokwenziwa eyenziwe nge-polysiloxane ewumugqa exutshwe nezigcwalisi eziqinisayo, izigcwalisi ezisebenzayo nezithasiselo, futhi iba i-elastomer efana nenethiwekhi ngemuva kokuvuthwa ngaphansi kwezimo zokushisa nengcindezi.Inokumelana okuhle kakhulu namazinga okushisa aphezulu naphansi, ukumelana nesimo sezulu, ukumelana ne-ozone, ukumelana ne-arc, ukwahlukanisa ugesi, ukumelana nomswakama, ukungena komoya okuphezulu kanye ne-inertia ye-physiological.Inezinhlobonhlobo zezinhlelo zokusebenza embonini yesimanje, i-elekthronikhi kanye nekagesi, izimoto, ezokwakha, ezokwelashwa, ukunakekelwa komuntu siqu kanye neminye imikhakha, futhi isiphenduke into ebaluleke kakhulu yokusebenza okuphezulu kwe-aerospace, imboni yezokuvikela kanye nezempi, ukukhiqiza okuhlakaniphile neminye imikhakha. .
4. Irabha ye-Fluorine
Irabha ye-fluorine isho into yerabha ene-fluorine equkethe ama-athomu e-fluorine kuma-athomu ekhabhoni eketango elikhulu noma amaketango aseceleni.Izakhiwo zayo ezikhethekile zinqunywa izici zesakhiwo sama-athomu e-fluorine.Irabha ye-fluorine ingasetshenziswa ku-250°C isikhathi eside, futhi izinga lokushisa eliphezulu lesevisi lingafinyelela ku-300°C, kuyilapho izinga lokushisa elilinganiselwe lesevisi ye-EPDM yendabuko kanye nerabha ye-butyl ingu-150°C kuphela.Ngaphezu kokumelana nezinga lokushisa eliphezulu, i-fluororubber inokumelana nowoyela okuhle kakhulu, ukumelana namakhemikhali, ukumelana ne-asidi ne-alkali, futhi ukusebenza kwayo okuphelele kungcono kakhulu kuzo zonke izinto zerabha elastomer.Isetshenziswa kakhulu ukumelana nowoyela wamarokhethi, imicibisholo, izindiza, imikhumbi, izimoto nezinye izimoto.Izinkambu ezinezinjongo ezikhethekile ezifana nokuvala uphawu namapayipi amelana nowoyela ziyizinto ezibalulekile emnothweni wezwe kanye nezimboni zezokuvikela kazwelonke nezempi.
5. Irabha ye-Acrylate (ACM)
Irabha ye-Acrylate (ACM) i-elastomer etholwe yi-copolymerization ye-acrylate njenge-monomer eyinhloko.Iketango layo eliyinhloko iketango lekhabhoni eligcwele, futhi amaqembu ayo aseceleni angamaqembu e-polar ester.Ngenxa yesakhiwo sayo esikhethekile, inezici eziningi ezinhle kakhulu, njengokumelana nokushisa, ukumelana nokuguga, ukumelana nowoyela, ukumelana ne-ozone, ukumelana ne-UV, njll., izakhiwo zayo zomshini nezici zokucubungula zingcono kunerabha ye-fluororubber ne-silicone, nokumelana nokushisa kwayo. , ukumelana nokuguga nokumelana nowoyela kuhle kakhulu.ku-nitrile rubber.I-ACM isetshenziswa kabanzi ezindaweni ezihlukene ezisezingeni eliphezulu nezimelana nowoyela, futhi isiphenduke into yokuvala ethuthukiswe futhi yakhuthazwa imboni yezimoto eminyakeni yamuva.
