1. Ubuningi obuphansi nokugcwalisa okuphezulu
Ukuminyana kwerabha ye-ethylene propylene kuwuhlobo lwerabha ephansi, futhi ukuminyana kwayo ngu-0.87.Ngaphezu kwalokho, inani elikhulu lamafutha lingagcwaliswa futhi kufakwe ama-fillers, ngakho-ke izindleko zemikhiqizo yenjoloba zingancishiswa, futhi ubungozi bentengo ephezulu yerabha eluhlaza ye-ethylene-propylene ingenziwa.Ngerabha ye-ethylene-propylene enenani eliphakeme le-Mooney, amandla angokwenyama kanye nemishini angancishiswa ngemva kokugcwalisa okuphezulu.hhayi enkulu.
2. Ukumelana nokuguga
Irabha ye-ethylene-propylene inokumelana okuhle kakhulu kwesimo sezulu, ukumelana ne-ozone, ukumelana nokushisa, ukumelana ne-asidi ne-alkali, ukumelana nomhwamuko wamanzi, ukuzinza kombala, izakhiwo zikagesi, ukugcwaliswa kwamafutha kanye nokushisa kwegumbi.Imikhiqizo yerabha ye-ethylene-propylene ingasetshenziswa isikhathi eside ku-120°C, futhi ingasetshenziswa okwesikhashana noma ngezikhathi ezithile ku-150-200°C.Ukwengeza i-ejenti efanele yokulwa nokuguga kungakhuphula izinga lokushisa layo lesevisi.Irabha ye-EPDM exhunywe nge-peroxide ingasetshenziswa ngaphansi kwezimo ezinzima.Ngaphansi kwezimo zokuhlushwa kwe-ozone ye-50pphm nokwelula kwe-30%, irabha ye-EPDM ingafinyelela ngaphezu kwe-150h ngaphandle kokuqhekeka.
3. Ukumelana nokugqwala
Ngenxa yokuntuleka kwe-polarity kanye nezinga eliphansi le-unsaturation yerabha ye-ethylene-propylene, inokumelana kahle namakhemikhali ahlukahlukene anjenge-alcohol, ama-acids, ama-alkali, ama-oxidants, amafriji, okokuhlanza, amafutha ezilwane nemifino, ama-ketones namafutha, njll. ;Kodwa kuzincibilikisi ze-aliphatic nezinephunga elimnandi (ezifana nophethiloli, benzene, njll.) kanye nokungaqini kahle kuwoyela wamaminerali.Ukusebenza kuzokwehla futhi ngaphansi kwesenzo sesikhathi eside se-asidi egxilile.
4. Ukumelana nomhwamuko wamanzi
Irabha ye-ethylene-propylene inokumelana kahle nomhwamuko wamanzi futhi ilinganiselwa ukuthi ingaphezu kokumelana nokushisa kwayo.Esitiyeni esishisa kakhulu ku-230°C, alukho ushintsho ekubukekeni ngemva cishe kwamahora ayi-100.Ngaphansi kwezimo ezifanayo, i-fluororubber, irabha ye-silicone, irabha ye-fluorosilicone, irabha ye-butyl, irabha ye-nitrile, nerabha yemvelo kuzoba nokuwohloka okusobala ekubukekeni ngemva kwesikhathi esifushane uma kuqhathaniswa.
5. Ukumelana namanzi ashisayo
Irabha ye-ethylene-propylene nayo inokumelana kangcono namanzi ashisayo, kodwa ihlobene eduze nazo zonke izinhlelo ze-vulcanization.Irabha ye-ethylene-propylene ene-dimorpholine disulfide kanye ne-TMTD njengoba uhlelo lwe-vulcanization lunoshintsho oluncane lwezakhiwo zemishini ngemva kokucwiliswa emanzini ashisa kakhulu ku-125 ° C izinyanga ezingu-15, futhi izinga lokunwetshwa kwevolumu liyi-0.3 kuphela%.
6. Izakhiwo zikagesi
Irabha ye-ethylene-propylene inezinto ezinhle kakhulu zokuvala ugesi kanye nokumelana ne-corona, futhi izakhiwo zayo zikagesi ziphakeme noma zisondele kunezo zenjoloba ye-styrene-butadiene, i-chlorosulfonated polyethylene, i-polyethylene kanye ne-polyethylene exhunywe ngokuphambana.
7. Ukuthambekela
Njengoba zingekho izingxenye ze-polar esakhiweni samangqamuzana enjoloba ye-ethylene-propylene, amandla ahlangene e-molecule aphansi, futhi iketango lamangqamuzana lingakwazi ukugcina ukuguquguquka kwezinto ezihlukahlukene, okwesibili kuphela kwerabha yemvelo kanye nerabha ye-butadiene, futhi isengakwazi ukugcina. ezingeni lokushisa eliphansi.
8. Ukunamathela
Ngenxa yokuntuleka kwamaqembu asebenzayo esakhiweni samangqamuzana enjoloba ye-ethylene-propylene, amandla ahlangene aphansi, futhi i-rubber kulula ukuqhakaza, futhi ukunamathela nokunamathelana kubi kakhulu.
I-Hebei CONQI VEHICLE FITTINGS Co., Ltd. yinkampani ezinikezele ukukhiqiza nokusabalalisa ipayipi lerabha elizenzakalelayo, ipayipi le-EPDM, ipayipi lebanga lokudla kanye nepayipi le-pvc njll enolwazi lokukhiqiza olucebile, ubuchwepheshe bokukhiqiza obuphambili kanye nohlelo oluphelele nolwesayensi lokuphatha ikhwalithi.Ngo-2009, inkampani yaqeda inani eliphelele lokuphuma kwezimboni lama-yuan ayizigidi ezingu-10.01 futhi yaqeda intela ye-warehouse engu-250, 000 yuan.Wonke amataniswa nama-OEM asekhaya angaphezu kuka-30 anjengeJinlong, Yutong, Ankai, neZhongtong, kanye namagatsha aphesheya kweVolvo neNdiya, New Zealand, Thailand, Taiwan, Poland, Israel, Britain, Egypt, Spain, Turkey, IBrazil, Singapore, Germany kanye namazwe angaphezu kuka-20 nezifunda bathole izinsiza zokusekela.Ngokunamathela emfundisweni "yokuthuthukiswa okuqhubekayo, ubuhle, ikhwalithi enhle kakhulu, nokwaneliseka kwamakhasimende", sithwebula ngokujulile ubuchwepheshe bamuva bamazwe ngamazwe nolwazi lomkhiqizo, sihlala siklama futhi sakha imikhiqizo emisha, futhi sihlinzeka ngamakhasimende .
